A switch port can be configured to be a Layer 3 routed port and behave like a regular router interface. Specifically, a routed port:
- Is not associated with a particular VLAN.
- Can be configured with a Layer 3 routing protocol.
- Is a Layer 3 interface only and does not support Layer 2 protocol.
Configure routed ports by putting the interface into Layer 3 mode with the no switchport interface configuration command. Then assign an IP address to the port. That's it!
