4.26.0F Duplicate IP

In older EOS releases the ingress interface was always included in LAG hash calculations input together with other

LAG Hashing 4.26.0F

This feature allows a Data Center (DC) operator to incrementally migrate their VXLAN network from IPv4 to IPv6

Ipv6 EVPN VXLAN 4.26.0F

ALPM (Algorithmic Longest Prefix Management) is a scheme in which the route prefix is split and stored across DEFIP

4.26.0F ALPM Flexible UFT

Multihoming in EVPN allows a single customer edge (CE) to connect to multiple provider edges (PE or tunnel endpoint).

There are use cases where all broadcast, multicast  and unknown MAC traffic are not needed to be flooded into the


The  Inband Network Telemetry eXport Data (INT XD) feature is used to gather flow, queue, drop telemetry

Telemetry 4.26.0F INT-XD

4.26.0F adds Latency ANalyZer (LANZ) support to the Arista 7170 series. LANZ monitors the egress queue usage through

4.22.1 4.26.0F 4.21.0

The `ptp forward-v1` command configures the switch to forward Precision Time Protocol version 1 packets as regular multicast traffic. By default, when PTP is enabled and PTPv1 packets are received on the PTP enabled interfaces, these packets are trapped by the CPU, logged and discarded.

Ptp 4.26.0F PTPv1

In EOS, BGP creates different update groups based on the outbound configuration. Different route maps or Routing

When an interface is overloaded with packets and goes beyond its buffering capabilities, packet drops become

This feature adds support for streaming the output of the following show command in Octa:. The

OpenConfig Octa 4.26.0F

This feature adds TLS support to the existing syslog logging mechanism. With the new added CLI commands, the user can

This article describes how to customize TCAM ( Ternary Content Addressable Memory ) lookup for each feature which uses TCAM.

This feature allows selecting Differentiated Services Code Point (DSCP) and Traffic Class (TC) values for packets at VTEPs along VXLAN encapsulation and decapsulation directions respectively. DSCP is a field in IP Header and TC is a tag associated with a packet within the switch, both influence the Quality of Service the packet receives. This feature can be enabled via configuration as explained later in this document.
