I have a few catalyst 3560's that i will be replacing some crappy dell switches. I want to set the switches to a domain so i wont have to config all respectively. These switches are going to be setup as a ring. feeding the ring will be my catalyst 6509. The current vlans on my 6509 need not be infulenced by this. can i set a trunk on my 6509 that is on the vtp domain and the vlans that reside there not be affected? Or is this not the approach i should take with this?
