No switchport trunking?

Can you setup a switch port to be both a "no switchport" to allow you to assign it an IP number AND enable it as a trunk to route VLAN traffic over the same interface?


If so...how would you go about setting this up? It seems if you issue a no switchport, then assign an IP you can't then enable trunking on the same port.

The "no switchport" command turns the port into a L3 routed port. If it is a L3 routed port it can't at the same time be a L2 trunk port.


So no you can't have the same port as both a routed port and a trunk port. What are you trying to achieve ? - remember that you can use SVI's to allocate IP addresses.

Jon,


I didn't think this was possible. Thanks for the confirmation.
