The following table describes the advanced mirroring features that are currently supported with links to their respective TOIs.

This document presents Arista Macro-Segmentation Service - Firewall (MSS-FW) deployment in a network with multiple Virtual Routing and Forwarding (VRF) instances.

This feature introduces the hardware forwarding support for IPv4 over IPv4, GRE-Tunnel interfaces on Arista Switches. A GRE-Tunnel interface acts as a logical interface which performs the GRE encapsulation or decapsulation. IPv6 payload over IPv4 GRE-Tunnel interfaces is supported with limitations (see Limitation section).

MRU (maximum receive unit) enforcement provides the ability to drop frames that exceed a configured threshold on the ingress interface.

In a symmetric network topology, for the same ECMP (Equal Cost Multi Path) route programmed at different devices in a switch layer, the various devices can program ECMP next hops in the FEC (Forwarding Equivalence Class) for that route in varying orders.

Network administrators require access to flow information that passes through various network elements, for the purpose of analyzing and monitoring their networks. This feature provides access to IP flow information by sampling traffic flows in ingress and/or egress directions on the interfaces on which it is configured. The samples are then used to create flow records, which are exported to the configured collectors in the IPFIX format. Egress Flow tracking is supported from EOS-4.29.0F on the DCS-7170B-64C series and supported on 7280, 7500 and 7800 series platforms from EOS-4.31.1".

Private VLAN is a feature that segregates a regular VLAN broadcast domain while maintaining all ports in the same IP subnet. There are three types of VLAN within a private VLAN
