Prior to EOS 14.15.0F, if a single packet hit both a PBR and an ACL rule, then only the hardware counters corresponding

Permitting traffic during ACL updates has been available for traffic steering in tap aggregation mode since EOS

Policy Based Routing (PBR) is a feature that is applied on routable ports, to preferentially route packets.  This is

Starting EOS 4.15.0F, a BGP route reflector can preserve the BGP attributes (next hop, local preference and metric)

This document describes the enhancements to Arista's IEEE 1588 PTP implementation introduced in EOS 4.15.0F.

QSFP+ modules that support TX power DOM will now display the reported TX power value via show interfaces transceiver.

RACL divergence enables the optimization of the utilization of hardware resources by installing ACLs only on the

TCAM sharing between different VLAN Interfaces when they have same ACL attached : Configurable via CLI

This feature allows to advertise routes learnt via BGP into IS IS network or IS IS routes into BGP network. It also

In an MLAG setup, routing on a switch (MLAG peer) is possible using its own bridge/system MAC, VARP MAC or VRRP MAC.

On 7500E, sFlow output interface feature enables sFlow to use the hardware provided output interface and

Source ARP with a virtual IP is a new VARP feature. The purpose of this feature is to change the ARP request header's sender IP and sender MAC address to the virtual IP and virtual MAC addresses. This change occurs for all the ARP request packets originating from the router that match a configured virtual subnet.

This is an infrastructure that provides management of SSL certificates, keys and profiles. SSL/TLS is an application-layer protocol that provides secure transport between client and server through a combination of authentication, encryption and data integrity. SSL/TLS uses certificates and private-public key pairs to provide this security.

Static ARP inspection is a security feature that verifies the source IP and the source MAC addresses of each received

A number of L4 7 appliances use the same MAC address to load balance services across two or more appliances that form the

Packet counters for Static and Twice NAT connections are now supported on the DCS 7150 series. This is a debug

The existing storm control interface configuration mode CLI commands have been extended to support the new

Subinterfaces are logical L3 interfaces that enable the division of a single Ethernet or Port-channel interface into multiple logical L3 interfaces based on the incoming 802.1q tag.  They are commonly used in the L2/L3 boundary.  They can also be used in the context of VRF-lite, by configuring each subinterface in a different VRF.

This feature adds support for standard BGP GSHUT (0xFFFF0000) community. GSHUT community is the community used in

For modular systems operating under the SSO redundancy policy, if  the system database agent (Sysdb) on the

This article describes the Tap Aggregation MPLS Pop feature. The purpose of this feature is to support tools that do not parse MPLS labels and therefore need the switch to remove (pop) the MPLS header.

The traffic steering policies used in tap aggregation mode allow steering traffic from tap to tool ports using ‘set

This TOI briefs the commands related to the traffic steering policies used in Tap Aggregation. These commands

As of EOS 4.15.0F, there are two general enhancements to Tap Aggregation on the 7500E platform in 4.15.0F:

As of 4.15.0F, tap aggregation can be configured in conjunction with other switching and routing features.  This

The Tap Aggregation Manager (TAM) is a GUI front end for configuring and monitoring Tap Aggregation features of

Packets which exceed the L2 Maximum Transmission unit (MTU) in EOS are dropped. The value of the L2 MTU is configurable for each Ethernet or Port-channel interface.

The VLAN mapping or translation feature provides the ability to map an arbitrary VLAN tag to a particular bridging VLAN on the switch. This mapping can be either bidirectional or applied only in one direction (incoming/outgoing).

The VXLAN Control Service (VCS) provides a mechanism by which hardware VTEPs share states between each other in order

MLAG provides Layer2 active/active redundancy. VXLAN is supported over an MLAG setup by having the two switches
