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 ho ld time is 180 seconds. To specify the ho ld 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
