We currently have a catalyst 4503. We are going to upgrade to a 4506. Not sure of the correct terminology, but I want internet connectivity on both switches while I convert the cat runs and patch cables from the 4503 to the 4506. Is it as simple as patching in a cable to the gig port on the 4503 to a gig port on the 4506. If it makes a difference, we dont have a router. Is there any special cmds or config on the 4506 to make this work. If this sound unclear or if you need more info, let me know. Thanks in advance.
