isdp holdtime
The isdp holdtime command configures the hold time for ISDP packets that
the switch transmits. The hold time specifies how long a receiving device
should store information sent in the ISDP packet before discarding it. The
range is given in seconds. Use the no form of this command to reset the
holdtime to the default.

User Guidelines
This command specifies the amount of time the partner device should
maintain the ISDP information. The local device uses the hold time in
packets received from the partner device. Configuring the hold time locally
does not change the amount of time displayed by the show isdp command.
Configure the hold time on the partner device to change the amount of time
the switch maintains the partner information.
Example
The following example sets isdp holdtime to 40 seconds.
console(config)#isdp holdtime 40
