Usage Guidelines

Note

Examples

CDP is enabled by default at the global level and on each supported interface in order to send or receive CDP information. However, some interfaces, such as ATM interfaces, do not support CDP.

The cdp enable, cdp timer, and cdp run commands affect the operation of the IP on demand routing feature (that is, the router odr Global configuration command). For more information on the router odr command, see the “On-Demand Routing Commands” chapter in the Cisco IOS Command Reference, Volume 2 of 3: Routing Protocols document.

In the following example, CDP is disabled on the Ethernet 0 interface only.

Router# show cdp

Global CDP information

Sending CDP packets every 60 seconds

Sending a holdtime value of 180 seconds

Sending CDPv2 advertisements is enabled

Router# config terminal

Router(config)# interface ethernet 0

Router(config-if)# no cdp enable
