Cdp And Switch Stacks - Cisco 3032 Software Configuration Manual

Configuring CDP

CDP and Switch Stacks

A switch stack appears as a single switch in the network. Therefore, CDP discovers the switch stack, not
the individual stack members. 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.
