Access Control Lists (ACL) use packet classification to mark certain packets going through the packet processor pipeline and then take configured action against them. Rules are defined based on various fields of packets and usually TCAM is used to match packets to rules.

The MPLS LFIB counters feature was enhanced to add support for counting labels that correspond to VRF termination labels. The full details of the MPLS LFIB counters feature can be found in the original

This feature introduces a flag to indicate to a gNMI client that the FIB (forwarding information base) or IPv4/IPv6 unicast AFT (abstract forwarding table) have converged and the snapshot is consistent with the device.

This feature allows IP FIB (Forwarding Information Base) export through the OpenConfig AFT YANG models.

SwitchApp is an FPGA based feature available on Arista’s 7130LB-Series and 7132LB-Series platforms. It performs ultra low latency Ethernet packet switching. The port to port latency is a function of the selected SwitchApp profile. Detailed latency measurements are available in the userguide on the Arista Support site.

Synchronous Ethernet (SyncE) provides support for frequency synchronization over Ethernet between devices traceable to an external frequency reference, like a primary reference clock, as specified in ITU G.8261.

Support for independently editing packets copied to multiple tool interfaces

This article describes a set of CLI commands to create TCAM profiles. The profile is composed of a set of TCAM features, with each feature having customized lookup key, actions and packet types to hit.

Virtual Private LAN Service (VPLS) appears in (almost) all respects as an Ethernet type service to customers of a Service Provider (SP). A VPLS glues together several individual LANs across a packet switched network to appear and function as a single bridged LAN.

This article describes the support of a VLAN filter for IP, IPV6 and MAC ACLs on the ingress ports. The users will be able to filter the packets by specifying a VLAN id in the ACL rule. VLAN id specified in the ACL rule is internal broadcast domain VLAN id.
