ISR Series Cards and Modules

The ports on these modules work as routed Layer 3 ports. Layer 2 switching between local ports on the module or between ports on the module and other ports within the router system is not supported. The port terminates Layer 2 trunks from externally connected switches, and Layer 2 trunk and VLAN information is not switched onto other ports in the system. The host router routes all traffic entering these modules.   Cisco Gigabit Ethernet WAN Modules do not support Power over Ethernet (PoE).
