What are the consequences of changing a port that is trunked to a routed port? I have a port that is trunked, and it's connected to our router (3745). Is there any benefit of changing it, or any major problems of changing it?
They do 2 different things.
A trunked port allows multiple vlans to travel down it and is seen as L2. Usually if connected to a router then you would use subinterfaces to route between the vlans.
A routed port will make the link between your switch and the router a routed link. If you change it to a routed port then you need to make sure you are routing for your vlans somewhere else.
Assuming this is a follow on from previous posts your inter-vlan routing will be done on the L3 switch and then you can have a routed P2P link between the L3 switch and the router. The router will now need to know how to get to the vlans on the L3 so either add a static route on the router pointing to the IP of the routed port on the L3 switch or exchange routes between the L3 switch and the router with a dynamic routing protocol.
