This TOI supplements the Ingress Traffic Policy applied on ingress interfaces. Please refer to that document for a description of Traffic Policies and field-sets. This TOI explains the Traffic Policies as applied in the egress direction on interfaces

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. For example, there can be a rule to match the packet source IP address against a list of IP addresses, and drop the packet if there is a match.

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

L3 subinterface counters do not count GRE terminated (decap) packets and other tunnel types packets such as decap

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

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.

TAP Aggregation support for the DCS 7280R3 and DCS 7500R3 series is documented below, including the release in which a
