Hello,

do you have a switch module installed in the router ? Can you post the output of 'show version' ?

As already noted by Gpauwen, unless there's a switch module installed in the router, the router doesn't by default support "switching".

However, possibly it will support bridging (L2) between its routed ports.

Additionally, if you have a switch to connect to the router, a routed port can be configured with subinterfaces that will work with a switch's trunk port (i.e. supporting multiple VLAN interfaces).
