Chapter 7 Configuring the Cisco Discovery Protocol

Enabling CDP

The following running-configuration example shows the results of entering the commands in Table 7-1.

!*************************** GLOBAL ***************************

cdp run

cdp holdTime 255 cdp timer 120

Enabling CDP

By default, CDP is disabled for the CSS. Use the cdp run global configuration command to enable CDP transmissions from the CSS to other neighboring Cisco CDP-compatible devices on the network.

For example:

(config)# cdp run

To disable CDP transmissions on the CSS, enter:

(config)# no cdp run

Setting the CDP Hold Time

The CDP hold time is the amount of time a receiving device retains the CDP information sent by the CSS (time-to-live information) before discarding this information. If a neighboring device does not receive a CDP message before the hold time expires, the neighboring device drops the CSS as a neighbor. By default, the hold time is 180 seconds. To specify the hold time, use the cdp holdTime global configuration command. Valid entries are 10 to 255 seconds.

To specify a CDP hold time of 255 seconds for the receiving device, enter:

(config)# cdp holdTime 255

To reset the CDP hold time back to the default value of 180 seconds, enter:

(config)# no cdp holdTime
