EOS 4.20.5F introduces support for encryption of control plane for OSPFv3 neighbors. OSPFv3 encryption provides

One of the steps in the BGP best path selection algorithm compares the IGP cost of the BGP next hop, preferring the path

This release adds support for mapping 802.1Q tags to VNIs on a per port basis through OVSDB when using the Hardware

Prior to this feature, Strata platforms (Please see Platform compatibility) used to support only destinationMac

The PHY test pattern CLI can be used to check the quality of the physical layer for an Ethernet interface. This is done by

This document describes how PIM non stop forwarding (NSF) works and its limitations. PIM supports non stop

The "Ping and Traceroute Source Configuration" feature provides the ability to configure a source interface for the

Prior to EOS 4.20.5, port channel min links feature evaluated minimum links in the following scenarios:

This feature removes an ARP entry when the physical port, on which the ARP entry's MAC address is learned, goes down.


This feature adds support for "sequential" processing of route-map 'set ext/community' clauses. This feature is enabled via a configuration knob and there is no change in behavior without enabling this knob. The default route-map processing behavior can be summarized as "add then delete".

Ingress PFC rates: The rate of these frames per port, per tx queue would be stored at the path given below, and the

This feature allows for setting BGP path attribute Multi Exit Discriminator for IGP routes advertised by BGP. This

Identity tagging is an existing Tap Aggregation feature that allows a 802.1Q header to be added to packets sent by tool ports with a configurable identity value.

This article describes user defined TCAM (Ternary Content Addressable Memory) profiles usage in Tap Aggregation.

This article describes the TAP Aggregation Traffic Steering features provided by the Extended TCAM Profile. This

This article describes the VXLAN header stripping feature for TAP Aggregation mode. The purpose of this feature is to remove the outer L2 and VXLAN headers on a selected tap port, with the inner frame forwarded to the associated tool port(s).
