			= Switch - Routed Ports =
			A routed port is a physical port that acts similarly to an interface on a router. Unlike an access port, a routed port is not associated with a particular VLAN. A routed port behaves like a regular router interface. Also, because Layer 2 functionality has been removed, Layer 2 protocols, such as STP, do not function on a routed interface. However, some protocols, such as LACP and EtherChannel, do function at Layer 3. Routed ports on a switch do not support sub-interfaces and are used for point-to-point links.

			(if-config)# '''no switchport''' !issued in interface configuration mode on a multilayer switch
