Enabling CDP on an Interface
CDP is enabled by default on all supported interfaces to send and to receive CDP information.
Switch clusters and other Cisco devices (such as Cisco IP Phones) regularly exchange CDP messages.
Disabling CDP can interrupt cluster discovery and device connectivity.
Note
CDP bypass is not supported and may cause a port go into err-disabled state.Note
Follow these steps to enable CDP on a port on which it has been disabled.
Before You Begin
CDP must be disabled on the port that you are trying to CDP enable on, or it cannot be enabled.
