Setting the CDP Transmission Rate
7-4
Cisco Content Services Switch Routing and Bridging Configuration Guide
OL-4580-01
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.
