SwitchApp is an FPGA-based feature available on Arista’s 7130LB-Series and 7132LB-Series platforms. 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 userguide on the Arista Support site.

A QoS Policy-maps policer is said to be shared when “set-policer” action is present under the qos features ( qos ip, qos ipv6, qos mac ) of a TCAM profile. When such shared QoS policy-map with policer action is configured on multiple interfaces, the policer instance is shared among all the interfaces, the policy-map is applied on. If in case, a unique policer instance is required per interface, a duplicate policy-map needs to be created for each interface, which will require additional TCAM resources.

Unicast Reverse Path Forwarding (uRPF) can help limit malicious IPv4/IPv6 traffic on a network. uRPF works by enabling the router to verify reachability (routing) of the source IP address (SIP) in the packet being forwarded. If the SIP is determined to be an invalid address, the packet is dropped.

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 is accomplished by incorporating MAC address learning, flooding, and forwarding functions in the context of pseudowires that connect these individual LANs across the packet switched network. LDP signaling is used for the setup and teardown of the mesh of pseudowires that constitute a given VPLS instance.

The feature will provide the ability to error disable local interfaces in a BGP VPWS pseudowire when the remote interface is shutdown or whenever we do not receive a response from BGP.
