We have a catalyst 5500 with supervisor IIIG and RSFC (NOT RSM). We need to route TCP/IP traffic between ethernet and token ring VLANs on this switch. I see in the CCO documentation that the RSFC does not support token ring. Do we have to use an external router or RSM to route between the token ring and ethernet, or is there a version of code for the sup IIIG that supports this?
