I reviewed some run-configuration of our switches and found there are not DG configured in them. A little confusion, could someone please let me know it is no necessary to configure a DG for a switch or not? Thank you.

I have a ready Cat4506, which will be for testing, including its hardware and configuration. Could someone let me know the procedures? Thanks.     David

How to replace Catalyst 4000E to 4506E? What's the basic processing steps? Any suggestion? Thanks.
