Policer and Filter on pseudowire subscriber logical interface

Policer and Filter are supported on the services side of an MPLS pseudowire subscriber logical interface. Policer defines a set of traffic rate limits and sets consequences for traffic that does not conform to the configured limits. Firewall filters restrict traffic destined for the Routing Engine based on its source, protocol, and application. Also, firewall filters limit the traffic rate of packets destined for the Routing Engine to protect against flood or denial-of-service (DoS) attacks.
