To view just the interfaces that are in Layer 2 mode, use the show interfaces switchport command in EXEC Privilege mode or EXEC mode. To tag frames leaving an interface in Layer 2 mode, you must assign that interface to a port-based VLAN to tag it with that VLAN ID. To tag interfaces, follow these steps: Step Task Command Syntax Command Mode 1 Access the interface vlan vlan-id INTERFACE VLAN mode of the VLAN to which you want to assign the interface.
