Usage Guidelines
Use the cdp enable command to enable the Cisco Discovery Protocol (CDP) feature at the switch level
or at the interface level. Use the no form of this command to disable this feature. When the interface link
is established, CDP is enabled by default
CDP version 1 (v1) and version 2 (v2) are supported in Cisco MDS 9000 Family switches. CDP packets
with any other version number are silently discarded when received.
Examples The following example disables the CDP protocol on the switch. When CDP is disabled on an interface,
one packet is sent to clear out the switch state with each of the receiving devices.
