I prefer to disable cdp when not explicitly required. However I am currently building a 3750 switch stack. The manual states "cdp discovers the switch stack... The switch stack sends CDP messages to neighboring network devices when there are changes to the switch stack membership, such as stack members being added or removed"
I have seen on several non-Ciscp forums that people seem to disable cdp on such switch stacks and do not mention any issues, but given the above I am sceptical.
My current thoughts are to leave cdp globally enabled but disable on the individual switch interfaces to minimise exposure.
What are others thoughts on this?
