EOS 4.27.1F TOI

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.

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. Multicast source traffic can reach the receivers which are separated by an IP cloud which is not configured for IP multicast routing by utilizing a GRE tunnel.

SwitchApp is an FPGA-based feature available on compatible Arista 7130 devices. It performs ultra low latency Ethernet packet switching. Its packet switching feature set, port count, and port to port latency are a function of the selected SwitchApp profile. Detailed latency measurements are available in the user guide 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
