EOS 4.26.1F TOI

The 7170 load balancer is a layer 4 load balancer providing high packet processing throughput.

802.1X is an IEEE standard protocol that prevents unauthorized devices from gaining access to the network.

The BGP-LS extension to be obsoleted allows IGP (OSPF/IS-IS) link state database information to be injected into BGP. This is typically used in deployments where some external component, (like a controller or Path Computation Engine) can do centralized path computations by learning the entire IGP topology through BGP-LS. The controller can then communicate the computed paths based on the BGP-LS updates to the head end device in the network. 

RPKI provides a mechanism to validate the originating AS of an advertised prefix. EOS support

Remove Private AS Ingress is a feature used for removing and replacing private AS numbers from inbound AS paths, so

EOS 4.26.1F release  added a platform configuration command to modify the dynamic MAC learning limit threshold on

This feature allows the user to have a custom COS To TC map per subinterfaces. By default,

This feature can be divided into 3 parts. Enable support for different threshold per Color per TX queue  We

This feature allows configuration of hash seed and hash fields used for LAG and ECMP hash computation.  This offers a

ECMP Hash visibility CLI determines the output interface for an ECMP set based on the flow parameters supplied by the

Normally the ingress router in the following diagram has no control over an autonomous system border router’s

In the Centralized Anycast Gateway configuration, the Spines are configured with EVPN IRB and are used as the IP

This feature is available when configuring Layer2 EVPN or EVPN IRB. As described in RFC7432 section 15

Forwarding destination prediction enables visibility into how a packet is forwarded through the switch and allows

This feature introduces the support for IPv4 ACL configuration under GRE and IPsec tunnel interfaces. The

The Segment security feature provides the convenience of applying policies on segments rather than interfaces or subnets. Hosts/networks are classified into segments based on prefixes. Grouping prefixes into segments allows for definition of policies that govern flow of traffic between segments. Policies define inter-segment or intra-segment communication rules, e.g. segment A can communicate with segment B but hosts in segment B can not communicate with each other.

In rare circumstances, a Single Event Upset may cause an underflow in the free list of buffers of a switch chip. This can

The document describes the support for dedicated and group ingress policing on interfaces without using QoS policy-maps to match on the traffic and apply policing.

IP Locking is an EOS feature configured on an Ethernet Layer 2 port.  When enabled, it ensures that a port will only

This feature enables IPv6 neighbor discovery (ND) proxies for IPv6 subnets on routed ports and L3 subinterfaces.

This feature provides support for multiple IS IS instances in the default VRF.  Multiple IS IS instances are only

Route redistribution is a process that allows a network to use a routing protocol to dynamically route traffic based

IS IS SR feature provides knobs to configure various types of segments which are distributed as part of IS IS LSPs (Link

The L2EVPN MPLS feature is available when configuring BGP in the multi agent routing protocol model.

As of EOS 4.22.0F, EVPN all active multihoming is supported as a standardized redundancy solution. For effective

Normally, a switch traps L2 protocol frames to the CPU. However, certain use-cases may require these frames to be forwarded.

LSPs formed by LDP normally follow IGP routing. The LDP speaker selects the downstream LSR for a particular prefix as

Media Access Control Security (MACsec) is an industry standard encryption mechanism that protects all traffic

Starting with the 4.26.1F release, EOS supports active mixed speed members in a port channel, allowing different

The TCP MSS clamping feature involves clamping the maximum segment size (MSS) in the TCP header of TCP SYN packets if it exceeds the configured MSS ceiling limit for the interface. Clamping MSS value helps in avoiding IP fragmentation in tunnel scenarios by ensuring that MSS is small enough to accommodate the extra overhead of GRE and tunnel outer IP headers.

This feature provides the ability to interconnect EVPN VXLAN domains. Domains may or may not be within the same data

Multipath color is a new multicast multipath mode for controlling PIM RPF selection. In the default multipath

In an OSPFv3 Area Border Router (ABR), area filters may be used to prevent specific prefixes from being announced by an

A pseudowire is usually transported over a single network path in order to preserve the packet ordering of each

This feature terminates GRE packets on a TapAgg switch by stripping the GRE header and then letting the decapped packets go through the normal TapAgg path. With this feature, we can use an L3 GRE tunnel to transit tapped traffic to the TapAgg switch over an L3 network. That would widely extend the available use cases for TapAgg.

This feature adds support for viewing the Digital Optical Monitoring (DOM) parameters for the optics that support
