Chapter 7 Configuring the Cisco Discovery Protocol

Setting the CDP Transmission Rate

Setting the CDP Transmission Rate

By default, the frequency at which the CSS transmits CDP packets to all receiving CDP-compatible devices is 60 seconds. To specify the frequency at which the CSS transmits CDP packets to all receiving CDP-compatible devices, use the cdp timer global configuration command. Valid entries are 5 to 254 seconds.

To change the CDP transmission rate for the CSS to 120 seconds, enter:

(config)# cdp timer 120

To reset the CDP timer to the default rate of 60 seconds, enter:

(config)# no cdp timer

Showing CDP Information

Use the show cdp command to display and verify CDP information for the CSS, such as frequency of transmissions and the hold time for transmitted CSS CDP information.

For example: (config)# show cdp

Global CDP information:

Sending CDP packets every 60 seconds

Sending a holdtime value of 16 seconds

TimeLastCdpSent: 0 days 00:00:30

The following example illustrates the CDP output on a Cisco Catalyst 8540 router using the Cisco IOS show cdp neighbors command.
