Cisco Gigabit Ethernet WAN Modules bring high-density Small Form-Factor Pluggable (SFP) and copper (RJ-45) 1 Gigabit and 10 Gigabit Ethernet (GE) connectivity to the Cisco 4000 Series Integrated Services Routers (ISRs). Providing maximum flexibility, the modules accelerate applications such as Ethernet WAN access, inter-VLAN routing, and high-speed connectivity to LAN switches and servers.
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.
