Introduction. PIM Static Source Discovery (PIM SM SSD) is a feature implemented as part of PIM SM. Familiarity with

PIM VRF feature adds VRF support to these existing multicast protocols: PIM SM, PIM BSR, IGMP and MSDP.

Ingress policing on front panel ports is supported on DCS 7010X and DCS 7050X since EOS4.14.0F. When ingress policing

Traffic is managed through policy maps that apply data shaping methods to specific data streams. A policy map is a data

QoS profiles have been applicable on fabric and front panel ports across all platforms from EOS 4.17.0F release

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

Port Security: Protect mode (PortSec Protect) is newly added to the Port Security feature and is designed to restrict

Port Channel member status logging on Arista switches allows logging of Ethernet interfaces joining or leaving a

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.

This feature makes ARP and ND packets use a higher priority output queue when software forwarded on the switch. Doing

Since, now there can be multiple inputs, conflicts may arise. Non conflicting configurations are when non default

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

Forward Error Correction (FEC) is required with some QSFP100 media to achieve error free operation of the link when

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

With the 13.0 release, CloudVision Cognitive Unified Edge (CV-CUE) can redirect onboarding clients to a dynamic URL defined by the RADIUS. If the  RADIUS access-accept request has a role and a redirection URL for a client, access points (AP) can redirect such client’s HTTP or HTTPS requests. 

Some data plane features on some switch platforms may require packets to be recirculated through the switch chip in

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

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

In the 14.0 release, CloudVision Cognitive Unified Edge (CV-CUE) introduces a new Report, WiFi-Radios Instantaneous.

Arista WM gathers a wealth of data about the wireless deployment. The data gathered includes Wireless Intrusion

Equal Cost Multi path (ECMP) provides the ability to load share traffic across multiple next hops.

The transmit power configured on UI is now treated as EIRP (Equivalent Isotropically Radiated Power) instead of

The BGP labeled unicast (LU) RFC is used to advertise BGP routes with a stack of MPLS labels, thereby allowing

This feature provides support for advertising IPv4 unicast Network Layer Reachability Information (NLRI) with

EOS 4.17.0F adds support for IPv4 address family in OSPFv3 (multiple address family support) based on RFC5838.

This feature allows routing traffic across two Vrf domains on the same switch using an external loopback cable

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

With the 13.0 release, you can integrate SAML SSO with a captive portal for authentication. The SAML integration functionality is only available for captive portals hosted on the Arista Cloud. It is not available if the captive portal is hosted on third-party servers or on the access point.

Sampled Mirroring is an extension of the Mirroring feature and sampling is a property of the
