All electronic devices are subject to interference from cosmic radiation. Arista products use a combination of

Arista MLAG supports STP for Layer 2 loop detection. In fact, most customers enable STP in their MLAG(s) to ensure no

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

Subinterfaces divide a single ethernet or port channel interface into multiple logical L2 or L3 interfaces based on the 802.1q or 802.1ad tags of incoming traffic. Subinterfaces are commonly used in the L2/L3 boundary device, but they can also be used to isolate traffic with 802.1q tags between L3 peers by assigning subinterfaces to different VRFs or different L2 bridging domains.

This document describes the Bgp Peer Flap Damping feature which allows session damping for peers with bfd enabled.

This article describes Dynamic NAT profile options that are configurable in EOS on DCS 7050X3 and CCS 720XP systems.

IPv4 Unicast Reverse Path Forwarding (uRPF) can help limit malicious IPv4 traffic on a network. uRPF works by enabling the router to verify reachability (routing) of the source IP address (SIP) in the packet being forwarded. If the SIP is determined to not be a valid address, the packet is dropped.

The multicast route counters count packets and bytes per group, source and vrf. Every multicast route will be counted when the feature is turned on if there are sufficient hardware counter resources available. 

Multicast NAT is a feature that performs NAT translations on multicast traffic. It can be configured under SVIs,

ARP and IPv6 Neighbor Discovery use a neighbor cache to store neighbor address resolutions.  The capacity of the

This document describes the OSPFv2 feature that allows the setting of “Down” (DN) bit in type-5 and type-7 LSAs. The DN Bit is a loop prevention mechanism implemented when OSPF is used as CE - PE IGP protocol. Its usage in OSPF is explained by RFC4576. By default, OSPF honors the DN-bit in type-3, type-5 or type-7 LSAs in non-default VRFs.

Traffic steering is an existing Tap Aggregation feature that supports redirection of traffic based on configurable

A VLAN-Aware bundle MAC-VRF allows multiple L2 domains to be advertised by a single MAC-VRF. The Ethernet Tag ID (ETID) as described in RFC7432 identifies the L2 domain within an EVPN instance corresponding to each route.

The VxLAN VTEP counters feature allows the device to count VxLAN packets received and sent by the device on a per VTEP
