CDP packets are sent with a time to live, or hold time, value. The receiving device will discard the CDP
information in the CDP packet after the hold time has elapsed. You can set the hold time lower than the
default setting of 180 seconds if you want the receiving devices to update their CDP information more
rapidly. The CDP hold time must be set to a higher number of seconds than the time between CDP
transmissions, which is set using the cdp timer command.
Examples
The following example sets the CDP holdtime:
SFS-7000P(config)# cdp holdtime 120
