Traffic Management

Traffic Management Conceptual Overview

Traffic is managed through policy maps that apply data shaping methods to specific data streams. A policy map is a data structure that identifies specific data streams and then defines shaping parameters that modify packets within the streams. The switch defines three types of policies:
  • Control Plane Policies: Control plane policy maps are applied to the control plane.
  • QoS Policies: QoS policy maps are applied to Ethernet and port channel interfaces.
  • PBR Policies: PBR policy maps are applied to Ethernet interfaces, port channel interfaces and switch virtual interfaces (SVIs).
  • PDP Policies: PDP policy maps are assigned to Ethernet interfaces.
Note: PDP is available only in eos versions 4.19.0F and above.
A policy map consists of classes. Each class contains an eponymous class map and traffic resolution commands.
  • A class map is a data structure that defines a data stream by specifying characteristics of data packets that comprise that stream. Each class map is typed as either QoS, control plane, PBR, or PDP and is available only to identically typed policy maps.
  • Traffic resolution commands specify data handling methods for traffic that matches a class map. Traffic resolution options vary by policy map type.

Data packets that enter an entity to which a policy map is assigned are managed with traffic resolution commands of the first class that matches the packets.

Control Plane Policies

The switch defines one control plane policy map named copp-system-policy. The copp-system-policy policy map is always applied to the control plane and cannot be removed from the switch. Other control plane policy maps cannot be added. Copp-system-policy consists of preconfigured classes, each containing a static class map and traffic resolution commands. Preconfigured classes cannot be removed from copp-system-policy.

Static class maps are provided by the switch and cannot be modified or deleted. The naming convention of static class maps is copp-system- name, where name differentiates the class maps. Static class maps have pre-defined internal conditions, are not based on ACLs, and are only listed in running-config as components of copp-system-policy. The sequence of static class maps in the policy map is not significant. Traffic resolution commands define minimum (bandwidth) and maximum (shape) transmission rates for data streams matching the corresponding class map.

Copp-system-policy can be modified through the following steps:
  • Add classes consisting of an eponymous dynamic class map and traffic resolution commands.

Dynamic class maps are user created, can be edited or deleted, filter traffic with a single IPv4 ACL, and are listed in running-config.

  • Change traffic resolution commands for a preconfigured class.

QoS Policies

QoS policy maps are user defined. The switch does not provide preconfigured QoS policy maps and in the default configuration, policy maps are not applied to any Ethernet or port channel interface. Policy maps and class maps are created and applied to interfaces through configuration commands.

A QoS policy map is composed of one or more classes. Each class contains an eponymous dynamic class map and traffic resolution commands. Dynamic class maps are user created, can be edited or deleted, filter traffic with a single IPv4 ACL, and are listed in running-config.

QoS traffic resolution commands perform one of the following:
  • Set the Layer 2 CoS field
  • Set the DSCP value in the ToS byte
  • Specify a traffic class queue
The last class in all QoS policy maps is class-default, which is composed as follows:
  • The class-default class map matches all traffic except IPv4 or IPv6 traffic and is not editable.
  • By default, class-default class contains no traffic resolution commands. Traffic resolution commands can be added through configuration commands.

Data packets that enter an interface to which a policy map is assigned are managed with traffic resolution commands that correspond to the first class that matches the packet.

PBR Policies

Policy-Based Routing (PBR) allows the operator to specify the next hop for selected incoming packets on an L3 interface, overriding the routing table. Incoming packets are filtered through a policy map referencing one or more ACLs, and matching packets are routed to the next hop specified.

A PBR policy map is composed of one or more classes and can include next-hop information for each class. It can also include single-line raw match statements, which have the appearance and function of a single line from an ACL. Each class contains an eponymous class map. Class maps are user-created, can be edited or deleted, filter traffic using IPv4 ACLs, and are listed in running-config.

PDP Policies

Note: PDP is available only in eos versions 4.19.0F and above.

Per-port Denial-of-service Protection (PDP) is a new, specialized, port-level packet classification and policing service, similar to the existing port-level QoS policy service, targeted specifically at identifying and rate limiting potential denial of service traffic.

Default policies and shared-policy support vary by platform:

Arad and Jericho platforms only shared policies are supported.

FM6000 and XP only unshared policies are supported

Trident II, Tomahawk, and Helix4 both shared and unshared policies are supported.

Creating a PDP policy and assigning it to an interface uses procedures similar to those for QoS, but with the following commands.

Traffic Management configuration Arad Platform Switches

Traffic policies are implemented by policy maps, which are applied to the control plane, or to L3 interfaces for Policy-Based Routing (PBR). Policy maps contain classes, which are composed of class maps and traffic resolution commands.

Traffic Management Conceptual Overview describes traffic policies.

Configuring Control Plane Traffic PoliciesArad Platform Switches

Default control plane traffic policies are implemented automatically without user intervention. These policies are modified by associating traffic resolution commands with static classes that comprise the control plane policy map.

Static Class Maps

Control plane traffic policies utilize static class maps, which are provided by the switch, are not editable, and cannot be deleted.

Editing the Policy Map

The only control plane policy map is copp-system-policy, which cannot be deleted. In its default form, copp-system-policy consists of the classes listed in copp-system-policy default classes: Arad Platform Switches. Although the underlying class map of each class cannot be edited, the traffic resolution commands can be adjusted. The default classes cannot be removed from the policy map and their sequence within the policy map is not editable.

Policy maps are modified in policy-map configuration mode. The policy-map type copp command enters policy-map configuration mode.

Example

This command enters policy-map configuration mode for editing copp-system-policy.
switch(config)#policy-map type copp copp-system-policy
switch(config-pmap-copp-system-policy)#

The class (policy-map (control-plane) Arad) command enters policy-map-class configuration mode, where traffic resolution commands are modified for the configuration mode class.

Example

This command enters policy-map-class configuration mode for the copp-system-lacp static class.
switch(config-pmap-copp-system-policy)#class copp-system-lacp
switch(config-pmap-c-copp-system-policy-copp-system-lacp)#

Two traffic resolution commands determine bandwidth parameters for class traffic:

Example

These commands configure a bandwidth range of 2000 to 4000 kilobits per seconds (kbps) for traffic filtered by the copp-system-lacp class map:
switch(config-pmap-c-copp-system-policy-copp-system-lacp)#bandwidth kbps 2000
switch(config-pmap-c-copp-system-policy-copp-system-lacp)#shape kbps 4000
switch(config-pmap-c-copp-system-policy-copp-system-lacp)#

Policy-map and policy-map-class configuration modes are group-change modes. Changes are saved with the exit command or discarded with the abort command. The show active command displays the saved version of policy map. The show pending command displays the modified policy map.

Example

These commands exit policy-map-class configuration mode, display the pending policy-map, then exit policy-map configuration mode, which saves the altered policy map to running-config.
switch(config-pmap-c-copp-system-policy-copp-system-lacp)#exit
switch(config-pmap-copp-system-policy)#show pending
policy-map type copp copp-system-policy
class copp-system-bpdu

class copp-system-lldp

class copp-system-lacp
shape kbps 4000
bandwidth kbps 2000

class copp-system-l3ttl1

class copp-system-l3slowpath


switch(config-pmap-copp-system-policy)#exit
switch(config)#

Applying Policy Maps to the Control Plane

The copp-system-policy policy map is always applied to the control plane. No commands are available to add or remove this assignment.

Displaying Policy Maps

The show policy-map interface type qos command displays the configured values of the policy maps classes and the number of packets filtered and dropped as a result of the class maps.

Example

These commands exit policy-map-class configuration mode, display the pending policy-map, then exit policy-map configuration mode, which saves the altered policy map to running-config.
switch(config)#show policy-map copp copp-system-policy
Service-policy input: copp-system-policy

Configuring QoS Traffic Policies Arad Platform Switches.

QoS traffic policies are implemented by creating class maps and policy maps, then applying the policy maps to Ethernet and port channel interfaces.

Creating Class Maps

QoS traffic policies utilize dynamic class maps that are created and modified in class-map configuration mode. The class-map type qos command enters class-map configuration mode.

Example

  • This command enters class-map configuration mode to create QoS class map named Q-CMap_1.
    switch(config)#class-map type qos match-any Q-CMap_1
    switch(config-cmap-Q-CMap_1)#

A class map contains one IPv4 access control list (ACL). The match ip access-group command assigns an ACL to the class map. Subsequent match commands replace the existing match command. Class maps filter traffic only on ACL permit rules. Deny ACL rules are disregarded.

Example

  • This command adds the IPv4 ACL named ACL_1 to the class map.
    switch(config-cmap-Q-CMap_1)#match ip access-group ACL_1
    switch(config-cmap-Q-CMap_1)#

Class-map configuration mode is a group-change mode. Changes made in a group-change mode are saved by exiting the mode. The show active command displays the saved version of class map. The show pending command displays the unsaved class map.

Example

  • The show active command indicates that the configuration mode class map is not stored in running-config. The show pending command displays the class map to be stored upon exiting class-map configuration mode.
    switch(config-cmap-Q-CMap_1)#show active
    switch(config-cmap-Q-CMap_1)#show pending
    class-map type qos match-any Q-CMap_1
     match ip access-group ACL_1
    
    switch(config-cmap-Q-CMap_1)#

The exit command returns the switch to global configuration mode and saves pending class map changes. The abort command returns the switch to global configuration mode and discards pending changes.

Example

  • This command exits class-map configuration mode and stores pending changes to running-config.
    switch(config-cmap-CP-CMAP_1)#exit
    switch(config)#show class-map type control-plane CP-CMAP_1
    Class-map: CP-CMAP_1 (match-any)
    Match: ip access-group name ACLv4_1
    switch(config)#

Creating Policy Maps

Policy maps are created and modified in policy-map configuration mode. The policy-map type quality-of-service command enters policy-map configuration mode.

Example

  • This command places the switch in policy-map configuration mode and creates a QoS policy map named Q-PMAP_1.
    switch(config)#policy-map type quality-of-service Q-PMAP_1
    switch(config-pmap-Q-PMAP_1)#

Policy map are edited by adding or removing classes. A class automatically contains its eponymous class map; traffic resolution commands are added or edited in policy-map-class configuration mode. The below command adds a class to the configuration mode policy map and places the switch in policy-map-class configuration mode, where traffic resolution commands are added to the class.

Example

  • This command adds the Q-CMap_1 class to the Q-PMAP_1 policy map and places the switch in policy-map-class configuration mode.
    switch(config-pmap-Q-PMAP_1)#class Q-CMap_1
    switch(config-pmap-c-Q-PMAP_1-Q-CMap_1)#

The set cos commands configure traffic resolution methods for data that passes the class map:

  • set cos sets the layer 2 CoS field.
  • set dscp sets the DSCP value in the ToS byte.
  • set traffic class specifies a traffic class queue.

Example

  • These commands configure the policy map to set the CoS field to 7 on packets filtered by the class map, then assigns those packets to traffic class 4.
    switch(config-pmap-c-Q-PMAP_1-Q-CMap_1)#set cos 7
    switch(config-pmap-c-Q-PMAP_1-Q-CMap_1)#set traffic-class 4
    switch(config-pmap-c-Q-PMAP_1-Q-CMap_1)#

Policy-map and policy-map-class configuration modes are group-change modes. Changes are saved with the exit command or discarded with the abort command. The show active and show pending commands display the saved and modified policy map versions, respectively.

Example

  • These commands exit policy-map-class configuration mode, display the pending policy-map, then exit policy-map configuration mode to save the altered policy map to running-config.
    switch(config-pmap-c-Q-PMAP_1-Q-CMap_1)#exit
    switch(config-pmap-Q-PMAP_1)#show pending
    policy-map type quality-of-service Q-PMAP_1
    class Q-CMap_1
    set cos 7
    set traffic-class 4
    
    class class-default
    
    switch(config-pmap-Q-PMAP_1)#exit
    switch(config)#

The last class in all QoS policy maps is class-default. The class-default class map matches all traffic except IPv4 or IPv6 traffic and provides no traffic resolution commands. The class-default class map is not editable; traffic resolution commands can be added to the class-default class.

To modify traffic resolution commands for the class-default class, enter policy-map-class configuration mode for the class, then enter the desired set commands.

Example

  • These commands enter policy-map-class configuration mode for class-default, configures the stream to enter traffic class 2, and saves the altered policy map to running-config.
    switch(config)#policy-map type quality-of-service Q-PMap_1
    switch(config-pmap-Q-PMap_1)#class class-default
    switch(config-pmap-c-Q-PMap_1-class-default)#set traffic-class 2
    switch(config-pmap-c-Q-PMap_1-class-default)#exit
    switch(config-pmap-Q-PMap_1)#exit
    switch(config)#show policy-map type qos Q-PMap_1
    Service-policy Q-PMap_1
    
    Class-map: Q-CMap_1 (match-any)
    Match: ipv6 access-group name ACLv6_1
     set cos 7
     set traffic-class 4
    
    Class-map: class-default (match-any)
     set traffic-class 2
    
    switch(config)#

Applying Policy Maps to an Interface

The service-policy type qos (Interface mode) command applies a specified policy map to the configuration mode interface.

  • These commands apply PMAP-1 policy map to Ethernet interface 8.
    switch(config)#interface ethernet 8
    switch(config-if-Et8)#show active
    switch(config-if-Et8)#service-policy input PMAP-1
    switch(config-if-Et8)#show active
    interface Ethernet8
     service-policy type qos input PMAP-1
    switch(config-if-Et8)#

Configuring PBR Policies Arad Platform Switches

Policy-Based Routing (PBR) is implemented by creating class maps and policy maps, then applying the policy maps to Ethernet interfaces, port channel interfaces or switch virtual interfaces (SVIs).

Creating PBR Class Maps

PBR policies utilize class maps that are created and modified in class-map configuration mode. The class-map type pbr command enters class-map configuration mode.

Example

This command enters class-map configuration mode to create a PBR class map named CMAP1.
switch(config)#class-map type pbr match-any CMAP1
switch(config-cmap-PBR-CMAP1)#

A class map contains one or more access control lists (ACLs). The match (policy-map (pbr)) command assigns an ACL to the class map. Subsequent match commands add additional ACLs to the class map. Class maps filter traffic only on ACL permit rules. Deny ACL rules are disregarded; if a class map includes ACLs with deny rules, the configuration reverts to its previous state.

Example

  • This command adds the ACL named ACL1 to the class map.
    switch(config-cmap-PBR-CMAP1)#match ip access-group ACL1
    switch(config-cmap-PBR-CMAP1)#

Class-map configuration mode is a group-change mode. Changes made in a group-change mode are saved by exiting the mode. The show active command displays the saved version of class map.

  • The show active command indicates that the configuration mode class map is not stored in running-config.
    switch(config-cmap-PBR-CMAP1)#show active
    switch(config-cmap-PBR-CMAP1)#

The exit command returns the switch to global configuration mode and saves pending class map changes. The abort command returns the switch to global configuration mode and discards pending changes.

Example

This command exits class-map configuration mode and stores pending changes to running-config.
switch(config-cmap-PBR-CMAP1)#exit
switch(config)#show class-map type pbr CMAP1
class-map type pbr match-any CMAP1
 10 match ip access-group ACL1
switch(config)#

Creating PBR Policy Maps

Policy maps are created and modified in policy-map configuration mode. The policy-map type pbr command enters policy-map configuration mode.

Example

This command enters policy-map configuration mode for creating a PBR policy map named PMAP1.
switch(config)#policy-map type pbr PMAP1
switch(config-pmap-PMAP1)#

Policy map are edited by adding or removing classes. A class automatically contains its eponymous class map; next-hop commands are added or edited in policy-map-class configuration mode. The class (policy-map (pbr)) command adds a class to the configuration mode policy map and places the switch in policy-map-class configuration mode, where next-hop commands are added to the class.

Example

  • This command adds the CMAP1 class to the policy map and places the switch in policy-map-class configuration mode.
    switch(config-pmap-PMAP1)#class CMAP1
    switch(config-pmap-c-PMAP1-CMAP1)#

The set nexthop (policy-map-class pbr) command configures the next hop for data that passes the class map.

  • This command configures the policy map to set the next hop to 10.12.0.5 on packets filtered by the class map.
    switch(config-pmap-c-PMAP1-CMAP1)#set nexthop 10.12.0.5
    switch(config-pmap-c-PMAP1-CMAP1)#

The set nexthop-group (policy-map-class(pbr) Arad) command configures a nexthop group as the next hop for data that passes the class map.

  • These commands configure the policy map PMAP1 to set the next hop to a nexthop group named GROUP1 for traffic defined by class map CMAP1.
    switch(config)#policy-map type pbr PMAP1
    switch(config-pmap-PMAP1)#class CMAP1
    switch(config-pmap-c-PMAP1-CMAP1)#set nexthop-group GROUP1
    switch(config-pmap-c-PMAP1-CMAP1)#

Policy-map and policy-map-class configuration modes are group-change modes. Changes are saved with the exit command or discarded with the abort command. The show active command displays the currently saved map version.

Example

These commands exit policy-map-class configuration mode, then exit policy-map configuration mode to save the altered policy map to running-config.
switch(config-pmap-c-PMAP1-CMAP1)#exit
switch(config-pmap-PMAP1)#exit
switch(config)#

Applying a PBR Policy Map to an Interface

The service-policy type pbr (Interface mode) command applies the specified PBR policy map to the configuration mode interface. Only one PBR service policy is supported per interface.

  • These commands apply the PMAP1 PBR policy map to Ethernet interface 8.
    switch(config)#interface ethernet 8
    switch(config-if-Et8)#service-policy type pbr input PMAP1
    switch(config-if-Et8)#

Hardware Decapsulation

When hardware decapsulation takes place, PBR policy maps on Arad platform switches match on outer packet headers (i.e., they match based on the attributes of the packet before it is decapsulated).

Traffic Management configuration FM6000 Platform Switches

Traffic policies are implemented by policy maps, which are applied to the control plane or an interface. Policy maps contain classes, which are composed of class maps and traffic resolution commands. Traffic Management Conceptual Overview describes traffic policies.

FM6000 platform switches support the following traffic policies:
  • Control plane policies manage control plane traffic.
  • QoS traffic policies manage traffic on Ethernet and port channel interfaces.

Configuring Control Plane Traffic PoliciesFM6000 Platform Switches

Default control plane traffic policies are implemented automatically without user intervention. These policies are modified by associating traffic resolution commands with static classes that comprise the control plane policy map.

Static Class Maps

Control plane traffic policies utilize static class maps, which are provided by the switch, are not editable, and cannot be deleted.

Editing the Policy Map

The only control plane policy map is copp-system-policy, which cannot be deleted. In its default form, copp-system-policy consists of the classes listed in copp-system-policy default classes: FM6000 Platform Switches. Although the underlying class map of each class cannot be edited, the traffic resolution commands can be adjusted. The default classes cannot be removed from the policy map and their sequence within the policy map is not editable.

Policy maps are modified in policy-map configuration mode. The policy-map type copp command enters policy-map configuration mode.

Example

  • This command enters policy-map configuration mode for editing copp-system-policy.
    switch(config)#policy-map type copp copp-system-policy
    switch(config-pmap-copp-system-policy)#

The class (policy-map (control-plane) FM6000) command enters policy-map-class configuration mode, where traffic resolution commands are modified for the configuration mode class.

Example

  • This command enters policy-map-class configuration mode for the copp-system-arp static class.
    switch(config-pmap-copp-system-policy)#class copp-system-arp
    switch(config-pmap-c-copp-system-policy-copp-system-arp)#

Two traffic resolution commands determine bandwidth parameters for class traffic:

Example

  • These commands configure a bandwidth range of 2000 to 4000 packets per seconds (pps) for traffic filtered by the copp-system-arp class map:
    switch(config-pmap-c-copp-system-policy-copp-system-arp)#bandwidth pps 2000
    switch(config-pmap-c-copp-system-policy-copp-system-arp)#shape pps 4000
    switch(config-pmap-c-copp-system-policy-copp-system-arp)#

Policy-map and policy-map-class configuration modes are group-change modes. Changes are saved with the exit command or discarded with the abort command. The show active command displays the saved version of policy map. The show pending command displays the modified policy map.

Example

  • These commands exit policy-map-class configuration mode, display the pending policy-map, then exit policy-map configuration mode, which saves the altered policy map to running-config.
    switch(config-pmap-c-copp-system-policy-CP-CMAP_1)#exit
    switch(config-pmap-copp-system-policy)#show pending
    policy-map type copp copp-system-policy
    class CP-CMAP_1
    shape pps 4000
    bandwidth pps 2000
    
    class copp-system-bpdu
    
    class copp-system-lldp
    
    class copp-system-lacp
    
    class copp-system-arp
    
    
    
    class copp-system-arpresolver
    
    class copp-system-default
    
    switch(config-pmap-copp-system-policy)#exit
    switch(config)#

Applying Policy Maps to the Control Plane

The copp-system-policy policy map is always applied to the control plane. No commands are available to add or remove this assignment.

Configuring QoS Traffic Policies FM6000 Platform Switches

QoS traffic policies are implemented by creating class maps and policy maps, then applying the policy maps to Ethernet and port channel interfaces.

Creating Class Maps

QoS traffic policies utilize dynamic class maps that are created and modified in class-map configuration mode. The class-map type qos command enters class-map configuration mode.

Example

This command enters class-map configuration mode to create QoS class map named Q-CMap_1.
switch(config)#class-map type qos match-any Q-CMap_1
switch(config-cmap-Q-CMap_1)#

A class map contains one IPv4 access control list (ACL). The match (class-map (qos) FM6000) command assigns an ACL to the class map. Subsequent match commands replace the existing match command. Class maps filter traffic only on ACL permit rules. Deny ACL rules are disregarded.

Example

This command adds the IPv4 ACL named ACL_1 to the class map.
switch(config-cmap-Q-CMap_1)#match ip access-group ACL_1
switch(config-cmap-Q-CMap_1)#

Class-map configuration mode is a group-change mode. Changes made in a group-change mode are saved by exiting the mode. The show active command displays the saved version of class map. The show pending command displays the unsaved class map.

Example

The show active command indicates that the configuration mode class map is not stored in running-config. The show pending command displays the class map to be stored upon exiting class-map configuration mode.
switch(config-cmap-Q-CMap_1)#show active
switch(config-cmap-Q-CMap_1)#show pending
class-map type qos match-any Q-CMap_1
 match ip access-group ACL_1

switch(config-cmap-Q-CMap_1)#

The exit command returns the switch to global configuration mode and saves pending class map changes. The abort command returns the switch to global configuration mode and discards pending changes.

Example

This command exits class-map configuration mode and stores pending changes to running-config.
switch(config-cmap-CP-CMAP_1)#exit
switch(config)#show class-map type control-plane CP-CMAP_1
Class-map: CP-CMAP_1 (match-any)
Match: ip access-group name ACLv4_1
switch(config)#

Creating Policy Maps

Policy maps are created and modified in policy-map configuration mode. The policy-map type quality-of-service command enters policy-map configuration mode.

Example

This command places the switch in policy-map configuration mode and creates a QoS policy map named Q-PMAP_1.
switch(config)#policy-map type quality-of-service Q-PMAP_1
switch(config-pmap-Q-PMAP_1)#

Policy map are edited by adding or removing classes. A class automatically contains its eponymous class map; traffic resolution commands are added or edited in policy-map-class configuration mode. The class (policy-map (qos) FM6000) command adds a class to the configuration mode policy map and places the switch in policy-map-class configuration mode, where traffic resolution commands are added to the class.

Example

This command adds the Q-CMap_1 class to the Q-PMAP_1 policy map and places the switch in policy-map-class configuration mode.
switch(config-pmap-Q-PMAP_1)#class Q-CMap_1
switch(config-pmap-c-Q-PMAP_1-Q-CMap_1)#

set (policy-map-class (qos) FM6000) commands configure traffic resolution methods for data that passes the class map:

  • set cos sets the layer 2 CoS field.
  • set dscp sets the DSCP value in the ToS byte.
  • set traffic class specifies a traffic class queue.

Example

These commands configure the policy map to set the CoS field to 7 on packets filtered by the class map, then assigns those packets to traffic class 4.
switch(config-pmap-c-Q-PMAP_1-Q-CMap_1)#set cos 7
switch(config-pmap-c-Q-PMAP_1-Q-CMap_1)#set traffic-class 4
switch(config-pmap-c-Q-PMAP_1-Q-CMap_1)#

Policy-map and policy-map-class configuration modes are group-change modes. Changes are saved with the exit command or discarded with the abort command. The show active and show pending commands display the saved and modified policy map versions, respectively.

Example

These commands exit policy-map-class configuration mode, display the pending policy-map, then exit policy-map configuration mode to save the altered policy map to running-config.
switch(config-pmap-c-Q-PMAP_1-Q-CMap_1)#exit
switch(config-pmap-Q-PMAP_1)#show pending
policy-map type quality-of-service Q-PMAP_1
class Q-CMap_1
set cos 7
set traffic-class 4

class class-default

switch(config-pmap-Q-PMAP_1)#exit
switch(config)#

The last class in all QoS policy maps is class-default. The class-default class map matches all traffic except IPv4 or IPv6 traffic and provides no traffic resolution commands. The class-default class map is not editable; traffic resolution commands can be added to the class-default class.

To modify traffic resolution commands for the class-default class, enter policy-map-class configuration mode for the class, then enter the desired set commands.

Example

These commands enter policy-map-class configuration mode for class-default, configures the stream to enter traffic class 2, and saves the altered policy map to running-config.
switch(config)#policy-map type quality-of-service Q-PMap_1
switch(config-pmap-Q-PMap_1)#class class-default
switch(config-pmap-c-Q-PMap_1-class-default)#set traffic-class 2
switch(config-pmap-c-Q-PMap_1-class-default)#exit
switch(config-pmap-Q-PMap_1)#exit
switch(config)#show policy-map type qos Q-PMap_1
Service-policy Q-PMap_1

Class-map: Q-CMap_1 (match-any)
Match: ipv6 access-group name ACLv6_1
 set cos 7
 set traffic-class 4

Class-map: class-default (match-any)
 set traffic-class 2

switch(config)#

Applying Policy Maps to an Interface

The service-policy type qos (Interface mode) command applies a specified policy map to the configuration mode interface.

  • These commands apply PMAP-1 policy map to Ethernet interface 8.
    switch(config)#interface ethernet 8
    switch(config-if-Et8)#show active
    switch(config-if-Et8)#service-policy input PMAP-1
    switch(config-if-Et8)#show active
    interface Ethernet8
     service-policy type qos input PMAP-1
    switch(config-if-Et8)#

Configuring PBR Policies FM6000 Platform Switches

Policy-Based Routing (PBR) is implemented by creating class maps and policy maps, then applying the policy maps to Ethernet interfaces, port channel interfaces or switch virtual interfaces (SVIs).

Creating PBR Class Maps

PBR policies utilize class maps that are created and modified in class-map configuration mode. The class-map type pbr command enters class-map configuration mode.

Example

  • This command enters class-map configuration mode to create a PBR class map named CMAP1.
    switch(config)#class-map type pbr match-any CMAP1
    switch(config-cmap-PBR-CMAP1)#

A class map contains one or more IPv4 access control lists (ACLs). The match (policy-map (pbr)) command assigns an ACL to the class map. Subsequent match commands add additional ACLs to the class map. Class maps filter traffic only on ACL permit rules. Deny ACL rules are disregarded; if a class map includes ACLs with deny rules, the configuration reverts to its previous state.

On FM6000 platform switches, counters are not supported, so a counters per-entry (ACL configuration modes) command in an ACL is ignored.

Example

  • This command adds the IPv4 ACL named ACL1 to the class map.
    switch(config-cmap-PBR-CMAP1)#match ip access-group ACL1
    switch(config-cmap-PBR-CMAP1)#

Class-map configuration mode is a group-change mode. Changes made in a group-change mode are saved by exiting the mode. The show active command displays the saved version of class map.

  • The show active command indicates that the configuration mode class map is not stored in running-config.
    switch(config-cmap-PBR-CMAP1)#show active
    switch(config-cmap-PBR-CMAP1)#

The exit command returns the switch to global configuration mode and saves pending class map changes. The abort command returns the switch to global configuration mode and discards pending changes.

Example

  • This command exits class-map configuration mode and stores pending changes to running-config.
    switch(config-cmap-PBR-CMAP1)#exit
    switch(config)#show class-map type pbr CMAP1
    class-map type pbr match-any CMAP1
     10 match ip access-group ACL1
    switch(config)#

Creating PBR Policy Maps

Policy maps are created and modified in policy-map configuration mode. The policy-map type pbr command enters policy-map configuration mode.

Example

  • This command enters policy-map configuration mode for creating a PBR policy map named PMAP1.
    switch(config)#policy-map type pbr PMAP1
    switch(config-pmap-PMAP1)#

Policy map are edited by adding or removing classes. A class automatically contains its eponymous class map; next-hop commands are added or edited in policy-map-class configuration mode. The class (policy-map (pbr)) command adds a class to the configuration mode policy map and places the switch in policy-map-class configuration mode, where next-hop commands are added to the class.

Example

  • This command adds the CMAP1 class to the policy map and places the switch in policy-map-class configuration mode.
    switch(config-pmap-PMAP1)#class CMAP1
    switch(config-pmap-c-PMAP1-CMAP1)#

The set nexthop (policy-map-class pbr) command configures the next hop for data that passes the class map.

  • This command configures the policy map to set the next hop to 10.12.0.5 on packets filtered by the class map.
    switch(config-pmap-c-PMAP1-CMAP1)#set nexthop 10.12.0.5
    switch(config-pmap-c-PMAP1-CMAP1)#

Policy-map and policy-map-class configuration modes are group-change modes. Changes are saved with the exit command or discarded with the abort command. The show active command displays the currently saved map version.

Example

  • These commands exit policy-map-class configuration mode, then exit policy-map configuration mode to save the altered policy map to running-config.
    switch(config-pmap-c-PMAP1-CMAP1)#exit
    switch(config-pmap-PMAP1)#exit
    switch(config)#

Applying a PBR Policy Map to an Interface

The service-policy type pbr (Interface mode) command applies the specified PBR policy map to the configuration mode interface. Only one PBR service policy is supported per interface.

  • These commands apply the PMAP1 PBR policy map to Ethernet interface 8.
    switch(config)#interface ethernet 8
    switch(config-if-Et8)#service-policy type pbr input PMAP1
    switch(config-if-Et8)#

Hardware Decapsulation

When hardware decapsulation takes place, PBR policy maps on FM6000 platform switches match on outer packet headers (i.e., they match based on the attributes of the packet before it is decapsulated).

Traffic Management configuration Petra Platform Switches

Traffic policies are implemented by policy maps, which are applied to the control plane. Policy maps contain classes, which are composed of class maps and traffic resolution commands. QoS traffic policies are not supported on 7500 Series switches.

Traffic Management Conceptual Overview describes traffic policies.

Configuring Control Plane Traffic PoliciesPetra Platform Switches

Default control plane traffic policies are implemented automatically without user intervention. These policies are modified by associating traffic resolution commands with static classes that comprise the control plane policy map.

Static Class Maps

Control plane traffic policies utilize static class maps, which are provided by the switch, are not editable, and cannot be deleted.

Editing the Policy Map

The only control plane policy map is copp-system-policy, which cannot be deleted. In its default form, copp-system-policy consists of the classes listed in copp-system-policy default classes: Petra Platform Switches. Although the underlying class map of each class cannot be edited, the traffic resolution commands can be adjusted. The default classes cannot be removed from the policy map and their sequence within the policy map is not editable.

Policy maps are modified in policy-map configuration mode. The policy-map type copp command enters policy-map configuration mode.

Example

This command enters policy-map configuration mode for editing copp-system-policy.
switch(config)#policy-map type copp copp-system-policy
switch(config-pmap-copp-system-policy)#

The class (policy-map (control-plane) Petra) command enters policy-map-class configuration mode, where traffic resolution commands are modified for the configuration mode class.

Example

  • This command enters policy-map-class configuration mode for the copp-system-lldp static class.
    switch(config-pmap-copp-system-policy)#class copp-system-lldp
    switch(config-pmap-c-copp-system-policy-copp-system-lldp)#

Two traffic resolution commands determine bandwidth parameters for class traffic:

Example

These commands configure a bandwidth range of 2000 to 4000 kilobits per seconds (kbps) for traffic filtered by the copp-system-arp class map:
switch(config-pmap-c-copp-system-policy-copp-system-lldp)#bandwidth kbps 2000
switch(config-pmap-c-copp-system-policy-copp-system-lldp)#shape kbps 4000
switch(config-pmap-c-copp-system-policy-copp-system-lldp)#

Policy-map and policy-map-class configuration modes are group-change modes. Changes are saved with the exit command or discarded with the abort command. The show active command displays the saved version of policy map. The show pending command displays the configured policy map.

Petra platform switches do not support all discrete rate values. When a bandwidth or shape command specifies a value that is not supported, the switch converts the rate to the next highest discrete value that it supports. The show policy-map interface type qos command displays the converted rate and not the user configured rate.

Example

These commands exit policy-map-class configuration mode, display the pending policy-map, then exit policy-map configuration mode, which saves the altered policy map to running-config.
switch(config-pmap-c-copp-system-policy-copp-system-lacp)#exit
switch(config-pmap-copp-system-policy)#show pending
policy-map type copp copp-system-policy
class copp-system-bpdu

class copp-system-lldp
shape kbps 4000
bandwidth kbps 2000

class copp-system-lacp

switch(config-pmap-copp-system-policy)#exit
switch(config)#

Changes are saved with the exit command or discarded with the abort command. The show active command displays the saved version of policy map. The show pending command displays the modified policy map.

Displaying Policy Maps

The show policy-map interface type qos command displays the traffic resolution rates of the policy maps classes and the number of packets filtered and dropped as a result of the class maps. The shape and bandwidth rates may differ from configured values, because the switch does not support all discrete rate values.

Example

These commands exit policy-map-class configuration mode, display the pending policy-map, then exit policy-map configuration mode, which saves the altered policy map to running-config.
switch(config)#show policy-map copp copp-system-policy
Service-policy input: copp-system-policy

Applying Policy Maps to the Control Plane

The copp-system-policy policy map is always applied to the control plane. No commands are available to add or remove this assignment.

Configuring QoS Traffic Policies – Petra Platform Switches

QoS traffic policies are not supported on Petra platform switches.

Configuring PBR Policies – Petra Platform Switches

PBR policies are not supported on Petra platform switches.

Traffic Management configuration Trident Platform Switches

Traffic policies are implemented by policy maps, which are applied to the control plane or an interface. Policy maps contain classes, which are composed of class maps and traffic resolution commands. Traffic Management Conceptual Overview describes traffic policies.

Trident platform switches support the following traffic policies:
  • Control plane policies manage control plane traffic.
  • QoS traffic policies manage traffic on Ethernet and port channel interfaces.

Configuring Control Plane Traffic PoliciesTrident Platform Switches

Default control plane traffic policies are implemented automatically without user intervention. These policies are modified by creating class maps and editing the policy map to include the new class maps.

Creating Class Maps

Control plane traffic policies utilize static and dynamic class maps. Static class maps are provided by the switch, are not editable, and cannot be deleted. Dynamic class maps are created and modified in class-map configuration mode. The class-map type copp command enters class-map configuration mode.

Example

This command enters class-map configuration mode for creating or editing a control plane dynamic class map named CP-CMAP_1.
switch(config)#class-map type copp match-any CP-CMAP_1
switch(config-cmap-CP-CMAP_1)#

Class maps contain one IPv4 or IPv6 access control list (ACL). The match (class-map (control-plane) Trident) command assigns an ACL to the class map. Subsequent match commands replace the existing match command. Class maps filter traffic only on ACL permit rules. Deny ACL rules are disregarded.

Example

This command assigns the IPv4 ACL named ACLv4_1 to the class map.
switch(config-cmap-CP-CMAP_1)#match ip access-group ACLv4_1
switch(config-cmap-CP-CMAP_1)#

Class-map configuration mode is a group-change mode. Changes are saved by exiting the mode. The show active command displays the saved version of class map. The show pending command displays the unsaved class map.

Example

The show active command indicates that the configuration mode class map is not stored in running-config. The show pending command displays the class map to be stored upon exiting class-map configuration mode.
switch(config-cmap-CP-CMAP_1)#show active
switch(config-cmap-CP-CMAP_1)#show pending
class-map type copp match-any CP-CMAP_1
 match ip access-group ACLv4_1

switch(config-cmap-CP-CMAP_1)#

The exit command returns the switch to global configuration mode and saves pending class map changes. The abort command returns the switch to global configuration mode and discards pending class map changes.

Example

This command exits class-map configuration mode and stores pending changes to running-config.
switch(config-cmap-CP-CMAP_1)#exit
switch(config)#show class-map type control-plane CP-CMAP_1
Class-map: CP-CMAP_1 (match-any)
Match: ip access-group name ACLv4_1
switch(config)#

Editing the Policy Map

The only control plane policy map is copp-system-policy, which cannot be deleted. In its default form, copp-system-policy consists of the classes listed in copp-system-policy default classes: Trident Platform Switches. Although the underlying class map of each class cannot be edited, the traffic resolution commands can be adjusted. The default classes cannot be removed from the policy map and their sequence within the policy map is not editable.

Policy maps are modified in policy-map configuration mode. The policy-map type copp command enters policy-map configuration mode.

Example

This command enters policy-map configuration mode for editing copp-system-policy.
switch(config)#policy-map type copp copp-system-policy
switch(config-pmap-copp-system-policy)#

Dynamic classes are inserted in front of the static classes. Classes automatically contain their eponymous class map; traffic resolution commands are created or edited in policy-map-class configuration mode. The class (policy-map (control-plane) Trident) command adds a class to the policy map and places the switch in policy-map-class configuration mode, where traffic resolution commands are added to the class.

Example

This command adds the CP-CMAP_1 class to the copp-system-policy policy map and places the switch in policy-map-class configuration mode.
switch(config-pmap-copp-system-policy)#class CP-CMAP_1
switch(config-pmap-c-copp-system-policy-CP-CMAP_1)#

Two traffic resolution commands determine bandwidth parameters for class traffic:

Example

These commands configure a bandwidth range of 2000 to 4000 packets per seconds (pps) for traffic filtered by the CP-CMAP_1 class map:
switch(config-pmap-c-copp-system-policy-CP-CMAP_1)#bandwidth pps 2000
switch(config-pmap-c-copp-system-policy-CP-CMAP_1)#shape pps 4000
switch(config-pmap-c-copp-system-policy-CP-CMAP_1)#

Example

Policy-map and policy-map-class configuration modes are group-change modes. Changes are saved with the exit command or discarded with the abort command. The show active command displays the saved version of policy map. The show pending command displays the modified policy map.

Example

These commands exit policy-map-class configuration mode, display the pending policy-map, then exit policy-map configuration mode, which saves the altered policy map to running-config.
switch(config-pmap-c-copp-system-policy-CP-CMAP_1)#exit
switch(config-pmap-copp-system-policy)#show pending

switch(config)#

Example

To modify traffic resolution commands for a static class, enter policy-map-class configuration mode for the class, then enter the desired bandwidth and shape commands.

Example

These commands enter policy-map-class configuration mode for copp-system-bpdu class, change the bandwidth range for the class, then save the altered policy map to running-config.
switch(config)#policy-map type copp copp-system-policy

Applying Policy Maps to the Control Plane

The copp-system-policy policy map is always applied to the control plane. No commands are available to add or remove this assignment.

Configuring QoS Traffic Policies Trident Platform Switches

QoS traffic policies are implemented by creating class maps and policy maps, then applying the policy maps to Ethernet and port channel interfaces.

Creating Class Maps

QoS traffic policies utilize dynamic class maps that are created and modified in class-map configuration mode. The class-map type qos command enters class-map configuration mode.

Example

  • This command enters class-map configuration mode to create QoS class map named Q-CMap_1.
    switch(config)#class-map type qos match-any Q-CMap_1
    switch(config-cmap-Q-CMap_1)#

A class map contains one IPv4 or IPv6 access control list (ACL). The match (class-map (qos) Trident) command assigns an ACL to the class map. Subsequent match commands replace the existing match command. Class maps filter traffic only on ACL permit rules. Deny ACL rules are disregarded.

Example

  • This command adds the IPv6 ACL named ACLv6_1 to the class map.
    switch(config-cmap-Q-CMap_1)#match ipv6 access-group ACLv6_1
    switch(config-cmap-Q-CMap_1)#

Class-map configuration mode is a group-change mode. Changes made in a group-change mode are saved by exiting the mode. The show active command displays the saved version of class map. The show pending command displays the unsaved class map.

Example

  • The show active command indicates that the configuration mode class map is not stored in running-config. The show pending command displays the class map to be stored upon exiting class-map configuration mode.
    switch(config-cmap-Q-CMap_1)#show active
    switch(config-cmap-Q-CMap_1)#show pending
    class-map type qos match-any Q-CMap_1
     match ipv6 access-group ACLv6_1
    
    switch(config-cmap-Q-CMap_1)#

The exit command returns the switch to global configuration mode and saves pending class map changes. The abort command returns the switch to global configuration mode and discards pending class map changes.

Example

  • This command exits class-map configuration mode and stores pending changes to running-config.
    switch(config-cmap-CP-CMAP_1)#exit
    switch(config)#show class-map type control-plane CP-CMAP_1
    Class-map: CP-CMAP_1 (match-any)
    Match: ip access-group name ACLv4_1
    switch(config)#

Creating Policy Maps

Policy maps are created and modified in policy-map configuration mode. The policy-map type quality-of-service command enters policy-map configuration mode.

Example

  • This command enters policy-map configuration mode for creating a QoS policy map named Q-PMAP_1.
    switch(config)#policy-map type quality-of-service Q-PMAP_1
    switch(config-pmap-Q-PMAP_1)#

Policy maps are edited by adding or removing classes. A class automatically contains its eponymous class map; traffic resolution commands are added or edited in policy-map-class configuration mode. The class (policy-map (qos) Trident) command adds a class to the configuration mode policy map and places the switch in policy-map-class configuration mode, where traffic resolution commands are added to the class.

Example

  • This command adds the Q-CMap_1 class to the Q-PMAP_1 policy map and places the switch in policy-map-class configuration mode.
    switch(config-pmap-Q-PMAP_1)#class Q-CMap_1
    switch(config-pmap-c-Q-PMAP_1-Q-CMap_1)#

The set (policy-map-class (qos) Trident) command configures traffic resolution methods for data that passes the class map:

  • set cos sets the layer 2 CoS field.
  • set dscp sets the DSCP value in the ToS byte.
  • set traffic class specifies a traffic class queue.

Example

  • These commands configure the policy map to set the CoS field to 7 on packets filtered by the class map, then assigns those packets to traffic class 4.
    switch(config-pmap-c-Q-PMAP_1-Q-CMap_1)#set cos 7
    switch(config-pmap-c-Q-PMAP_1-Q-CMap_1)#set traffic-class 4
    switch(config-pmap-c-Q-PMAP_1-Q-CMap_1)#

Policy-map and policy-map-class configuration modes are group-change modes. Changes are saved with the exit command or discarded with the abort command. The show active and show pending commands display the saved and modified policy map versions, respectively.

Example

  • These commands exit policy-map-class configuration mode, display the pending policy-map, then exit policy-map configuration mode to save the altered policy map to running-config.
    switch(config-pmap-c-Q-PMAP_1-Q-CMap_1)#exit
    switch(config-pmap-Q-PMAP_1)#show pending
    policy-map type quality-of-service Q-PMAP_1
    class Q-CMap_1
    set cos 7
    set traffic-class 4
    
    class class-default
    
    switch(config-pmap-Q-PMAP_1)#exit
    switch(config)#

The last class in all QoS policy maps is class-default. The class-default class map matches all traffic except IPv4 or IPv6 traffic and provides no traffic resolution commands. The class-default class map is not editable; traffic resolution commands can be added to the class-default class.

To modify traffic resolution commands for the class-default class, enter policy-map-class configuration mode for the class, then enter the desired set commands.

Example

  • These commands enter policy-map-class configuration mode for class-default, configures the stream to enter traffic class 2, and saves the altered policy map to running-config.
    switch(config)#policy-map type quality-of-service Q-PMap_1
    switch(config-pmap-Q-PMap_1)#class class-default
    switch(config-pmap-c-Q-PMap_1-class-default)#set traffic-class 2
    switch(config-pmap-c-Q-PMap_1-class-default)#exit
    switch(config-pmap-Q-PMap_1)#exit
    switch(config)#show policy-map type qos Q-PMap_1
    Service-policy Q-PMap_1
    
    Class-map: Q-CMap_1 (match-any)
    Match: ipv6 access-group name ACLv6_1
     set cos 7
     set traffic-class 4
    
    Class-map: class-default (match-any)
     set traffic-class 2
    
    switch(config)#

Applying Policy Maps to an Interface

The service-policy type qos (Interface mode) command applies a specified policy map to the configuration mode interface.

Example

  • These commands apply PMAP-1 policy map to Ethernet interface 8.
    switch(config)#interface ethernet 8
    switch(config-if-Et8)#show active
    switch(config-if-Et8)#service-policy input PMAP-1
    switch(config-if-Et8)#show active
    interface Ethernet8
     service-policy type qos input PMAP-1
    switch(config-if-Et8)#

Configuring PBR Policies Trident Platform Switches

Policy-Based Routing (PBR) is implemented by creating class maps and policy maps, then applying the policy maps to Ethernet interfaces, port channel interfaces or switch virtual interfaces (SVIs).

Creating PBR Class Maps

PBR policies utilize class maps that are created and modified in class-map configuration mode. The class-map type pbr command enters class-map configuration mode.

Example

This command enters class-map configuration mode to create a PBR class map named CMAP1.
switch(config)#class-map type pbr match-any CMAP1
switch(config-cmap-PBR-CMAP1)#

A class map contains one or more access control lists (ACLs). The match (policy-map (pbr)) command assigns an ACL to the class map. Subsequent match commands add additional ACLs to the class map. Class maps filter traffic only on ACL permit rules. Deny ACL rules are disregarded; if a class map includes ACLs with deny rules, the configuration reverts to its previous state.

Examples

  • This command adds the ACL named ACL1 to the class map.
    switch(config-cmap-PBR-CMAP1)#match ip access-group ACL1
    switch(config-cmap-PBR-CMAP1)#

Class-map configuration mode is a group-change mode. Changes made in a group-change mode are saved by exiting the mode. The show active command displays the saved version of class map.

  • The show active command indicates that the configuration mode class map is not stored in running-config.
    switch(config-cmap-PBR-CMAP1)#show active
    switch(config-cmap-PBR-CMAP1)#

The exit command returns the switch to global configuration mode and saves pending class map changes. The abort command returns the switch to global configuration mode and discards pending changes.

Example

This command exits class-map configuration mode and stores pending changes to running-config.
switch(config-cmap-PBR-CMAP1)#exit
switch(config)#show class-map type pbr CMAP1
class-map type pbr match-any CMAP1
 10 match ip access-group ACL1
switch(config)#

Creating PBR Policy Maps

Policy maps are created and modified in policy-map configuration mode. The policy-map type pbr command enters policy-map configuration mode.

Example

  • This command enters policy-map configuration mode for creating a PBR policy map named PMAP1.
    switch(config)#policy-map type pbr PMAP1
    switch(config-pmap-PMAP1)#

Policy map are edited by adding or removing classes. A class automatically contains its eponymous class map; next-hop commands are added or edited in policy-map-class configuration mode. The class (policy-map (pbr)) command adds a class to the configuration mode policy map and places the switch in policy-map-class configuration mode, where next-hop commands are added to the class.

Example

  • This command adds the CMAP1 class to the policy map and places the switch in policy-map-class configuration mode.
    switch(config-pmap-PMAP1)#class CMAP1
    switch(config-pmap-c-PMAP1-CMAP1)#

The set nexthop (policy-map-class pbr) command configures the next hop for data that passes the class map.

  • This command configures the policy map to set the next hop to 10.12.0.5 on packets filtered by the class map.
    switch(config-pmap-c-PMAP1-CMAP1)#set nexthop 10.12.0.5
    switch(config-pmap-c-PMAP1-CMAP1)#

Policy-map and policy-map-class configuration modes are group-change modes. Changes are saved with the exit command or discarded with the abort command. The show active command displays the currently saved map version.

  • These commands exit policy-map-class configuration mode, then exit policy-map configuration mode to save the altered policy map to running-config.
    switch(config-pmap-c-PMAP1-CMAP1)#exit
    switch(config-pmap-PMAP1)#exit
    switch(config)#

Applying a PBR Policy Map to an Interface

The service-policy type pbr (Interface mode) command applies the specified PBR policy map to the configuration mode interface. Only one PBR service policy is supported per interface.

  • These commands apply the PMAP1 PBR policy map to Ethernet interface 8.
    switch(config)#interface ethernet 8
    switch(config-if-Et8)#service-policy type pbr input PMAP1
    switch(config-if-Et8)#

Hardware Decapsulation

When hardware decapsulation takes place, PBR policy maps on Trident platform switches match on inner packet headers (i.e., they match based on the attributes of the decapsulated packet).

Traffic Management configuration Trident II Platform Switches

Traffic policies are implemented by policy maps, which are applied to the control plane or an interface. Policy maps contain classes, which are composed of class maps and traffic resolution commands. Traffic Management Conceptual Overview describes traffic policies.

Trident platform switches support the following traffic policies:
  • Control plane policies manage control plane traffic.
  • QoS traffic policies manage traffic on Ethernet and port channel interfaces.

Configuring Control Plane Traffic PoliciesTrident II Platform Switches

Default control plane traffic policies are implemented automatically without user intervention. These policies are modified by associating traffic resolution commands with static classes that comprise the control plane policy map.

Static Class Maps

Control plane traffic policies utilize static class maps, which are provided by the switch, are not editable, and cannot be deleted.

Editing the Policy Map

The only control plane policy map is copp-system-policy, which cannot be deleted. In its default form, copp-system-policy consists of the classes listed in copp-system-policy default classes: Trident II Platform Switches. Although the underlying class map of each class cannot be edited, the traffic resolution commands can be adjusted. The default classes cannot be removed from the policy map and their sequence within the policy map is not editable.

Policy maps are modified in policy-map configuration mode. The policy-map type copp command enters policy-map configuration mode.

Example

This command enters policy-map configuration mode for editing copp-system-policy.
switch(config)#policy-map type copp copp-system-policy
switch(config-pmap-copp-system-policy)#

Example

The class (policy-map (control-plane) Trident II) command enters policy-map-class configuration mode, where traffic resolution commands are modified for the configuration mode class.

Example

This command enters policy-map-class configuration mode for the copp-system-lacp static class.
switch(config-pmap-copp-system-policy)#class copp-system-lacp
switch(config-pmap-c-copp-system-policy-copp-system-lacp)#

Two traffic resolution commands determine bandwidth parameters for class traffic:

Example

These commands configure a bandwidth range of 2000 to 4000 packets per seconds (pps) for traffic filtered by the copp-system-lacp class map:
switch(config-pmap-c-copp-system-policy-copp-system-lacp)#bandwidth pps 2000
switch(config-pmap-c-copp-system-policy-copp-system-lacp)#shape pps 4000
switch(config-pmap-c-copp-system-policy-copp-system-lacp)#

Example

Policy-map and policy-map-class configuration modes are group-change modes. Changes are saved with the exit command or discarded with the abort command. The show active command displays the saved version of policy map. The show pending command displays the modified policy map.

Example

These commands exit policy-map-class configuration mode, display the pending policy-map, then exit policy-map configuration mode, which saves the altered policy map to running-config.
switch(config-pmap-c-copp-system-policy-copp-system-lacp)#exit

Guidelines

Petra does not support all discrete rate values. When a specified discrete value is not supported, the switch converts the rate to the next highest discrete value that it supports. The show command displays the converted rate and not the user-configured rate.

Example

  • These commands configure a minimum bandwidth of 500 kbps for data traffic specified by the class map copp-system-lldp of the default control-plane policy map. Because the switch does not support the discrete value of 500 kbps, it converts the bandwidth up to 651 kbps.

class (policy-map (control-plane) Arad)

The class command places the switch in policy-map-class (control plane) configuration mode, which is a group change mode for changing bandwidth and shape parameters associated with a specified class. All changes in a group change mode edit session are pending until the end of the session.

A policy map is an ordered list of classes. The control plane policy map contains 20 static classes. Each class contains an eponymous class map and may contain bandwidth and shape commands.

  • The class map identifies a data stream.
  • bandwidth command defines the streams minimum transmission rate through the control plane.
  • shape command defines the streams maximum transmission rate through the control plane.

Static class maps identify a data stream by definition. Each data packet is managed by commands of the first class whose map matches the packets content. Dynamic classes are not supported for control plane policing on Arad platform switches.

Each class corresponds to a transmission queue. Queue scheduling is round-robin until bandwidth rate for a queue is exceeded. Scheduling becomes strict-priority with CPU queue number determining priority until the shape rate is reached. Packets are dropped after the shape rate is exceeded.

The exit command returns the switch to policy-map configuration mode. Saving policy-map-class changes also require an exit from policy-map mode, which saves pending policy-map-class and policy-map changes to running-config and returns the switch to global configuration mode. The abort command discards pending changes, returning the switch to global configuration mode.

The no class and default class commands remove policy-map-class commands for the specified class assignment from the policy map.

class (policy-map (control-plane) Trident)

The class command places the switch in policy-map-class (control plane) configuration mode, which is a group change mode for changing bandwidth and shape parameters associated with a specified class. The command adds the specified class to the policy map if it was not previously included. All changes in a group change mode edit session are pending until the end of the session.

A policy map is an ordered list of classes. The control plane policy map contains 18 static classes and up to 30 dynamic classes. Dynamic classes contain an eponymous class map. All classes may contain bandwidth and shape commands.

  • The class map identifies a data stream.
  • bandwidth command defines the streams minimum transmission rate through the control plane.
  • shape command defines the streams maximum transmission rate through the control plane.

Dynamic class maps identify a data stream with an ACL assigned by match (class-map (control-plane) Trident). Static class maps identify a data stream by definition. Each data packet is managed by commands of the first class whose map matches the packets content.

Static classes are provided with the switch and cannot be removed from the policy map or modified by the class command. Dynamic classes are user defined and added to the policy map by this command. Dynamic classes are always placed in front of the static classes. Bandwidth and shape parameters are editable for all classes.

Each class corresponds to a transmission queue. Queue scheduling is round-robin until bandwidth rate for a queue is exceeded. Scheduling becomes strict-priority with CPU queue number determining priority until the shape rate is reached. Packets are dropped after the shape rate is exceeded.

The exit command returns the switch to policy-map configuration mode. Saving policy-map-class changes also require an exit from policy-map mode, which saves pending policy-map-class and policy-map changes to running-config and returns the switch to global configuration mode. The abort command discards pending changes, returning the switch to global configuration mode.

The no class and default class commands remove policy-map-class commands for the specified class assignment from the policy map. The class is removed from the policy map if it is a dynamic class.

class (policy-map (pbr))

The class (policy-map (pbr)) command places the switch in policy-map-class (pbr) configuration mode, which is a group change mode that modifies the specified class of the configuration mode Policy-Based Routing (PBR) policy map. The command adds the class to the policy map if it was not previously included in the policy map. All changes in a group change mode edit session are pending until the mode is exited, and can be canceled by using the abort command.

A PBR policy map is an ordered list of classes. Each class contains an eponymous class map and can contain set commands to specify next hop. Classes without set commands translate to no action being performed on that class of packets.

  • The class map identifies a data stream through ACLs. Class maps are configured in class-map (pbr) configuration mode.
  • Set commands can be used to specify the next hop for a given class. Set commands are configured in policy-map-class (pbr) configuration mode.

PBR policy maps can also contain one or more raw match statements which filter incoming traffic without using ACLs. Data packets are managed by commands of the first class or raw match statement matching the packets contents.

The exit command returns the switch to policy-map (pbr) configuration mode. However, saving policy-map-class changes also requires an exit from policy-map (pbr) configuration mode. This saves all pending policy map and policy-map-class changes to running-config and returns the switch to global configuration mode. The abort command discards pending changes, returning the switch to global configuration mode.

The no class and default class commands remove the class assignment from the configuration mode policy map by deleting the corresponding class configuration from running-config.

Example

  • This command creates the control plane class map named CP-MAP-1 and places the switch in class-map configuration mode.
    switch(config)#class-map type copp match-any CP-CMAP-1
    switch(config-cmap-CP-CMAP-1)#

class-map type pbr

The class-map type pbr command places the switch in class-map (pbr) configuration mode for the specified class map, and creates the class map if one does not already exist. Class-map (pbr) configuration mode is a group change mode that modifies a class map for Policy-Based Routing (PBR). PBR class maps contain one or more match statements which filter incoming traffic using ACLs. PBRs can then use these class maps to set next-hop IP addresses for the traffic that matches them. (Classes without set commands translate to no action being performed on that class of packets.)

The exit command saves pending class map changes to running-config, then returns the switch to global configuration mode. Class map changes are also saved by directly entering a different configuration mode. The abort command discards pending changes and returns the switch to global configuration mode.

The no class-map type pbr and default class-map type pbr commands delete the specified class map by removing the corresponding class-map type pbr command and its associated configuration.

    switch(config-cmap-MAP1)#

class-map type qos

The class-map type qos command places the switch in Class-Map (qos) configuration mode, which is a group change mode that modifies a QoS dynamic class map. A dynamic class map is a data structure that uses access control lists (ACLs) to define a data stream by specifying characteristics of data packets that comprise that stream. QoS policy maps use class maps to specify the traffic (to which the policy map is assigned) that is transformed by policy map criteria.

The exit command saves pending class map changes to running-config, then returns the switch to global configuration mode. Class map changes are also saved by entering a different configuration mode. The abort command discards pending changes and returns the switch to global configuration mode.

The no class-map type qos and default class-map type qos commands delete the specified class map by removing the corresponding class-map type qos command and its associated configuration. The class-map and class-map type qos commands are equivalent.

service-policy type pbr (Interface mode)

The service-policy pbr command applies the specified Policy-Based Routing (PBR) policy map to the configuration mode interface. A PBR policy map is a data structure that consists of class maps that identify specific packets and the next hops for those packets. Policy maps are applied to Ethernet or port channel interfaces to manage traffic. Only one service policy is supported per interface.

The no service-policy pbr and default service-policy pbr commands remove the service policy assignment from the configuration mode interface by deleting the corresponding service-policy pbr command from running-config.

Command Mode

Interface-Ethernet configuration

Interface-port-channel configuration

Interface-VLAN configuration

Command Syntax

service-policy type pbr TRAFFIC_DIRECTION map_name

no service-policy type pbr TRAFFIC_DIRECTION map_name

default service-policy type pbr TRAFFIC_DIRECTION map_name

Parameters

  • TRAFFIC_DIRECTION IP address or peer group name. Values include:
    • input Policy map applies to inbound packet streams.
  • map_name Name of policy map.

Guidelines

A policy map that is attached to a port channel interface takes precedence for member interfaces of the port channel over their individual Ethernet interface configuration. Members that are removed from a port channel revert to the policy map implementation specified by its Ethernet interface configuration.

Related Commands

Example

  • This command applies the PBR policy map PMAP1 to Ethernet interface 8.
    switch#config
    switch(config)#interface ethernet 8
    switch(config-if-Et8)#service-policy type pbr input PMAP1
    switch(config-if-Et8)#

service-policy type pdp (Interface mode)

The service-policy pdp command assigns the specified Per-port Denial-of-service (PDP) policy map to the configuration mode interface.

The no service-policy pdp and default service-policy pdp commands remove the service policy assignment from the configuration mode interface by deleting the corresponding service-policy pdp command from running-config.

Note:

PDP is available only in eos versions 4.19.0F and above.

Command Mode

Interface-Ethernet configuration

Command Syntax

service-policy type pdp input map_name

no service-policy pdp input map_name

default service-policy pdp input map_name

Parameters

  • map_name name of policy map.

Example

  • This command assigns the PDP policy map PMAP1 to Ethernet interface 8.
    switch#config
    switch(config)#interface ethernet 8
    switch(config-if-Et8)#service-policy type pdp input PMAP1
    switch(config-if-Et8)#

service-policy type qos (Interface mode)

The service-policy command applies a specified policy map to the configuration mode interface. A policy map is a data structure that identifies data traffic through class maps, then specifies actions to classify the traffic (by setting the traffic class), mark the traffic (by setting the cos and dscp values), and police the traffic (by setting the police rate) through data packet field modifications.

The no service-policy and default service-policy commands remove the service policy assignment from the configuration mode interface by deleting the corresponding service-policy command from running-config.

Command Mode

Interface-Ethernet configuration

Interface-port-channel configuration

Interface-VLAN configuration

Command Syntax

service-policy [type qos] TRAFFIC_DIRECTION map_name

no service-policy [type qos] TRAFFIC_DIRECTION map_name

default service-policy [type qos] TRAFFIC_DIRECTION map_name

Parameters

  • type qos Parameter has no functional effect.
  • TRAFFIC_DIRECTION Direction of data stream to which command applies. Options include:
    • input Policy map applies to inbound packet streams.
  • map_name Name of policy map.

Guidelines

A policy map that is attached to a port channel interface takes precedence for member interfaces of the port channel over their individual Ethernet interface configuration. Members that are removed from a port channel revert to the policy map implementation specified by its Ethernet interface configuration.

DCS-7500E and DCS-7280E limitations:

  • A maximum of 31 QoS service policies per chip may be applied on L3 interfaces.
  • Applying different QoS service policies to an SVI and its member interfaces causes unpredictable behavior.
  • When an SVI on which QoS service policies are applied experiences partial failure due to limited hardware resources, a forwarding agent restart will cause unpredictable behavior.
  • Policy-map programming may fail when QoS service policies are applied on two SVIs if an event causes a member interface to switch membership from one to the other. To change the VLAN membership of an interface in this case, remove the interface from one VLAN before adding it to the other.
  • Outgoing COS rewrite is not supported.
  • QoS policy-map counters are not supported.

DCS-7010, DCS-7050, DCS-7050X, DCS-7250X, and DCS-7300X limitations:

  • When the same policy map is applied to multiple SVIs, TCAM resources are not shared.
  • A policy map applied to an SVI will result in TCAM allocation on all chips whether SVI members are present or not.
  • Applying different QoS service policies to an SVI and its member interfaces causes unpredictable behavior.
