This feature adds support for the front panel Ethernet (Et) interface counters on the platforms listed below and enables the Et interfaces to dynamically adopt the counter values (packet and error)1 of interfaces (Switch, App interfaces etc.) related to the currently running FPGA application, based on user or default configuration. All Arista FPGA applications are supported. Both the receive and transmit packet counters can be independently configured for each interface, as desired. Counters are supported for interfaces of any speed including agile ports.

Generic UDP Encapsulation (GUE) is a general method for encapsulating packets of arbitrary IP protocols within a UDP tunnel. GUE provides an extensible header format with optional data. In this release, decap capability of GUE packets of variant 1 header format has been added. This variant allows direct encapsulation using the UDP header without the GUE header. The inner payload could be one of IPv4, IPv6, or MPLS.

This feature introduces the support for IPv4 ACL configuration under GRE and IPsec tunnel interfaces and IPv6 ACL configuration under GRE tunnel interfaces. The configured ACL rules are applied to a tunnel terminated GRE packet i.e. any IPv4/v6-over-GRE-over-IPv4 that is decapsulated by the GRE tunnel-interface on which the ACL is applied, or a packet terminated on IPsec tunnel i.e, IPv4-over-ESP-over-encrypted-IPv4 packet that is decapsulated and decrypted by the IPsec tunnel interface on which the ACL is applied.

Hardware Table Capacity Monitoring is a new feature to keep track of the capacity and utilization of various hardware forwarding resources and generate alerts/syslogs when the utilization exceeds a threshold value. Users can keep track of the current usage statistics using a single show command, and also configure thresholds on a per-resource basis, to be notified about any high-utilization upfront, before reaching any resource limits. The Main use-case would be for troubleshooting in overflow situations and avoid overflows altogether by taking corrective actions on high utilization.

This feature introduces support for scaling both IPv4 and IPv6 hosts on our devices. Existing MDB profiles offer a maximum host scale of 128k with unique MAC rewrites. However, if hosts share the MAC rewrites, the scale can reach up to 204k. To address this issue, we are introducing a new MDB profile that will support a host scale of up to 192k when each host has a unique MAC rewrite. If hosts share the MAC rewrites, the scale can reach up to 256k.

This is an extension to BGP EVPN VPNs that allow us to use iBGP as the PE-CE protocol. This feature also provides a way to isolate the customer’s network BGP attributes from the SP backbone’s attributes, by saving them into a special attribute called ATTR_SET, code 128. This separation introduces a “route server” model that allows the customer’s BGP path attributes to be stored in the SP backbone along with the VPN-IPv4/v6 paths.

Prior to this feature, these updates (on a VXLAN setup) are synchronized by sending an UDP packet (one packet per update) containing the IP/MAC/VLAN information from the MLAG peer where the ARP/ND packet is received to the other MLAG peer.

When IP in IP decapsulation is configured, incoming packets with an outer IP header having IpProto=4 (IP in IP) and IpDest matching the one configured will be decapsulated, meaning that the outer IP header will be removed from the packet and all subsequent forwarding decisions will be based on the inner IP header.
