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.

Unicast Reverse Path Forwarding (uRPF) can help limit malicious IP traffic on a network. uRPF works by enabling the

This feature introduces hardware forwarding support of IPv4 multicast traffic over IPv4 GRE tunnel interfaces in

SwitchApp is an FPGA based feature available on Arista’s 7130LB-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.   SwitchApp application in the FPGA provides L2 forwarding functionality including 802.1Q VLANs, STP, IGMP Snooping, and other features. More forwarding functionality is available with application software extension update. The specific set of forwarding features supported depends on the SwitchApp profile. Please see below for details regarding the features in profile.
