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).
