I want to create a new VLAN and just want to be sure that my thought process for this is correct. I first need to create the VLAN on our switch, and then need to create the sub interfaces on the Router's ethernet inteface for the VLAN's. Does the port on the switch that the Routers Ethernet interface is connected need to be configured as a trunk ports as well
Yes. You would create the subinterface on the router and then assign it a vlan "encapsulation dot1q ". The switch will need to be set to form a trunk on the interface also. If I remember correctly router subinterfaces won't participate in DTP so you would need to manually create the trunk on the switch side.
