Configuring CDP

This section describes how to configure CDP.

Enabling or Disabling CDP Globally

CDP is enabled by default. You can disable CDP and then reenable it.
CDP must be enabled on the device before you enable CDP on any interfaces. If CDP is disabled globally
and you enable CDP on specified interfaces, CDP will not be active on those interfaces. The system does not
return an error message when this occurs.
