Filtering Packets Received on an Interface Set Overview
You can configure a standard stateless firewall filter term that matches packets tagged for a specified interface set. An interface set groups two or more physical or logical interfaces into a single interface-set name. You can filter packets received on an interface set for protocol-independent, IPv4, IPv6, MPLS, VPLS, or bridging traffic.
You can also configure a standard stateless firewall filter term or a service filter term that matches on packets tagged for a specified interface group. For more information, see Filtering Packets Received on a Set of Interface Groups Overview.
