Arista switches provide several mirroring features. Filtered mirroring to CPU adds a special destination to the mirroring features that allows the mirrored traffic to be sent to the switch supervisor. The traffic can then be monitored and analyzed locally without the need of a remote port analyzer. Use case of this feature is for debugging and troubleshooting purposes.

In an MLAG setup, routing on a switch (MLAG peer) is possible using its own bridge/system MAC, VARP MAC or VRRP MAC. When a peer receives an IP packet with destination MAC set to one of the aforementioned MACs, the packet gets routed if the hardware has enough information to route the packet. Before introducing this feature, if the destination MAC is peer’s bridge MAC, the packet is L2 bridged on the peer-link and the routing takes place on the peer. This behavior to use the peer-link to bridge the L3 traffic to the peer is undesirable especially when the MLAG peers can route the packets themselves.

With this feature, IPv4 routes may be resolved via MPLS-over-GRE next-hop group to be able to push one MPLS label and then GRE encapsulate the resulting labelled IPv4 packet before sending out of the egress interface.

Nexthop group counters provide the ability to count packets and bytes associated with each tunnel nexthop, irrespective of the number of times it appears in one or more nexthop groups. In other words, if a nexthop group entry shares a tunnel resource with another entry, they will also share the same counter.
