Virtual Trunking Protocol (VTP) shouldn't be in the discussion
. I know LLDP deals with Network Discovery, along the same lines of CDP. I may have described VTP, my point being is that I do not want either a Cisco Protocol (CDP) or an open-source Protocol (LLDP) telling my VoIP device which vLAN is which.
and v2win: it helps also when people move ports thinking they can without calling the Helpdesk first
, that way when the port dies, and i can point out that they moved ports without telling IT they get very bashful. I have sites in Utah, Idaho, etc, I can't just walk over and move the port back.
