This feature adds support for offloading BFD Transmit path to hardware (ASIC) for specific types of BFD sessions. This will improve accuracy of transmit timer implementations for BFD (especially with fast timers like 50 ms) and relieve pressure on the main CPU in scenarios of scale.

EOS-4.24.0 adds support for hardware-accelerated sFlow on R3 systems. Without hardware acceleration, all sFlow processing is done in software, which means performance is heavily dependent on the capabilities of the host CPU. Aggressive sampling rates also decrease the amount of processing time available for other EOS applications.

IP Locking is an EOS feature configured on an Ethernet Layer 2 port. When enabled, it ensures that a port will only permit IP and ARP packets with IP source addresses that have been authorized. As of EOS-4.25.0F release update, IP Locking can run in two modes - IPv4 Locking (which will be referred to as IP Locking) and IPv6 Locking, which can be configured using the commands mentioned in the below sections. IP Locking prevents another host on a different interface from claiming ownership of an IP address through either IP or ARP spoofing.

Ethernet VPN (EVPN) is an extension of the BGP protocol introducing a new address family: L2VPN (address family number 25) / EVPN (subsequent address family number 70). It is used to exchange overlay MAC and IP address reachability information between BGP peers using type-2 routes, but additionally, EVPN supports the exchange of layer 3 IPv4 and IPv6 overlay routes through the extensions described in (type 5 EVPN routes).

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.

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.
