EOS 4.29.1F TOI

Access Control Lists (ACL) use packet classification to mark certain packets going through the packet processor pipeline and then take configured action against them. Rules are defined based on various fields of packets and usually TCAM is used to match packets to rules.

This feature introduces hardware forwarding support of IPv4 multicast traffic over IPv4 GRE tunnel interfaces in Arista Switches.

SWIM (SWI Modularized) is a change to the format of EOS.swi. It is a feature that is mostly internal, but has a few customer visible side-effects one should be mindful of.

SwitchApp is an FPGA based feature available on Arista’s 7130LB-Series and 7132LB-Series platforms. It performs ultra low latency Ethernet packet switching. The port to port latency is a function of the selected SwitchApp profile. Detailed latency measurements are available in the userguide on the Arista Support site.

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

Virtual Private LAN Service (VPLS) appears in (almost) all respects as an Ethernet type service to customers of a Service Provider (SP). A VPLS glues together several individual LANs across a packet switched network to appear and function as a single bridged LAN.

This document describes the VRF selection policy and VRF fallback feature. A VRF selection policy contains match rules that specify certain criteria (e.g. DSCP, IP protocol) as well as a resulting action to select a VRF in which to do the FIB lookup.
