Arista switches use the hashing algorithm to load balance traffic among LAG (Link Aggregation Group) members

This solution allows delivery of both IPv4 and IPv6 multicast traffic in an IP-VRF using an IPv6 multicast in the underlay network. The protocol used to build multicast trees in the underlay network is IPv6 PIM-SSM.

The IPv6 Neighbor Discovery protocol performs Neighbor Unreachability Detection (NUD) in order to determine if two

With this feature, IPv4 and IPv6 packets matching a static nexthop-group route can be encapsulated within an IP-in-IP tunnel and forwarded

Policy-Based Routing (PBR) provides the flexibility of routing according to custom-defined policies

With this, IPv6 routes can be configured pointing to a static Nexthop group of 2 types:. Type

IPv6 Router Advertisement Consistency Logging, when enabled, allows for notification through syslogging of

The document describes an extension of the decap group feature, that allows IPv6 addresses to be configured and used as part of a group. IP-in-IP packets with v6 destination matching a configured decap group IP will be decapsulated and forwarded based on the inner header. That will allow any IP-to-IP packet type to be decapsulated, i.e. IPv4 in IPv4, IPv4 in IPv6, IPv6 in IPv4 and IPv6 in IPv6.

This feature adds IPv6 VRF support to Open Shortest Path First(OSPF) Protocol version 3. It allows for OSPFv3

EOS 4.15.0F is introducing support of IPv6 management capabilities inside a VRF. This means existing management

This feature adds the support for IPv6 unicast in a VRF context in EOS. This entails static routing and dynamic

IS IS adjacency uptime describes the uptime or downtime of neighbors since the last state change.

Bidirectional Forwarding Detection(BFD) is a low overhead protocol designed to provide rapid detection of

The difference between the two forms of authentication is in the level of security provided. In case of clear text authentication, the password is specified as text in the authentication TLV, making it possible for an attacker to break the authentication by sniffing and capturing IS-IS PDUs on the network.

IS IS Graceful Restart adds support for Restart Signaling for IS IS, IETF RFC 5306. When IS IS is used

By default if there's a hostname configured on the switch, it is used as the IS IS hostname. It is also possible to

An IS IS router can be configured as Level 1 2 which can form adjacencies and exchange routing information with both

IS IS Multi Topology support enables an IS IS router to compute a separate topology for IPv4 and IPv6 links in the

This feature enables an Arista switch to run the IS IS routing protocol over a tunnel interface to another IS IS

Segment Routing provides mechanism to define end-to-end paths within a topology by encoding paths as sequences of sub-paths or instructions. These sub-paths or instructions are referred to as “segments”. IS-IS Segment Routing (henceforth referred to as IS-IS SR) provides means to advertise such segments through IS-IS protocol.

Level 1 2 routers set attached bit in their Level 1 LSPs to indicate their reachability to the rest of the network. A

SPF Timers can be used in IS-IS to throttle the frequency of shortest-path-first (SPF) computations. In networks with a lot of churn, using these timers will help in containing the effect of network disruptions arising out of frequent SPF runs.

The default behavior of a level 1 router running IS IS is to install a default route to a level 1 2 router present in a

This feature adds Intermediate System to Intermediate System (IS IS) support for IP version 6 (IPv6) address family

This feature provides a way to export non ISIS routes into level 1, level 2 or both by using route map's set clause. The

This feature extends the IS IS set overload bit command to support wait for BGP option. In scenarios

At a high level, L1 profiles are a set of configurations which allow EOS users to change the numbering scheme and default L1 configurations of all front panel interfaces across their network switch. On Arista network switches, front panel transceiver cages are exposed as ports which are numbered sequentially: 1, 2, 3, 4, etc. These identifiers are usually marked on the front panel to allow for easier identification.

L2 protocol packets - LLDP, LACP and STP are trapped to the CPU by default. This feature allows for disabling the per protocol trap on a given set of interfaces.

In our current implementation, on a switch with default startup config or no config, all ports come up in access

This feature is used to connect a Layer 3 EVPN VXLAN network to an Adaptive Virtual Topology (AVT) WAN network using dynamic path selection (DPS) tunnels. One or a pair of WAN routers are configured to serve as the VXLAN gateway. On the control plane, the configured VXLAN gateway handles EVPN IP-PREFIX route exchanges between the VXLAN network and the WAN network. On the data plane, the configured VXLAN gateway decapsulates the VXLAN packets received from the VXLAN network and encapsulates them into the DPS tunnels and sends them to the AVT WAN network. 

This feature is available when configuring BGP in the multi agent routing protocol model. Ethernet

L3 interface ingress counters can be used to count routable traffic coming into the box on sub interfaces and vlan

LACP on Loopback Interfaces allows for Active Port Channels on one or more interfaces whose link endpoints terminate

LACP State Transition Event Monitoring on Arista switches allows for quick and filterable viewing of LACP state

LAGs are allocated hardware resources on transition from one member (software LAG) to two members (hardware LAG) and

Switches can now use two LAG partitions (A and B) to support double the number of available Port Channels dictated by the chosen LAG mode. This is useful if the selected LAG mode does not allow the creation of the desired number of Port Channels on a single partition.

Arista switches use the hashing algorithm to load balance traffic among LAG (Link Aggregation Group) members

This document describes the current status of LANZ on DCS 7500R, DCS 7280R and DCS 7020R, for both polling and

LANZ on 7160S 32CQ, 7160 48YC6 and 7160 48TC6 adds support for monitoring congestion on front panel ports with Start,

Loop protection is a loop detection and prevention method which is independent of Spanning Tree Protocol (STP) and is not disabled when the switch is in switchport backup mode or port is in discarding state. The LoopProtect agent has a method to detect loops and take action based on the configuration by the user. In order to find loops in the system, a loop detection frame is sent out periodically on each interface that loop protection is enabled on. The frame carries broadcast destination MAC address, bridge MAC source address, OUI Extended EtherType 0x88b7 as well as information to specify the origins of the packet.

The Label Distribution Protocol (LDP) is a protocol in the Multiprotocol Label Switching (MPLS) context that allows

The LDP pseudowire feature provides support for emulating Ethernet connections over a Multiprotocol Label

Leaf Smart System Upgrade (SSU) provides the ability to upgrade the EOS image with minimal traffic disruption.Note: It is possible that SSU shutdown and bootup are not supported in the same image. If a product has shutdown support in image A and bootup support in a later image B, then SSU upgrade cannot be performed from image A to any images earlier than image B, including image A itself. However, upgrading from image A to image B onwards is allowed.

Line system commands are used to apply configuration and query the status of line system modules in EOS. The supported line system modules are the OSFP-AMP-ZR and the QSFP-AMP-ZR.

Link Fault Signalling (LFS) is a mechanism by which remote link faults are asserted over a link experiencing

Local Authentication (also known as authentication survivability) is the ability of access points (AP) to authenticate and onboard clients to the network using root CA certificates through the integrated EAP server of the AP. Use Local Authentication when the RADIUS servers are not reachable to authenticate the clients. It is typically a temporary authentication mechanism; avoid using it as a primary authentication. If there are certificate chains, you must upload the root CA certificate along with the certificate chain.

With the 14.0 release, CloudVision Cognitive Unified Edge (CV-CUE) removes the Wireless Manager(WM) UI dependency for login and for applying the service license. You will no longer be redirected to WM and can now directly login to CV-CUE from the UI.
