FDP Overview 7

To change the FDP update timer, enter a command such as the following at the global CONFIG level of the CLI.

Brocade(config)# fdp timer 120

Syntax: [no] fdp timer <secs>

The <secs> parameter specifies the number of seconds between updates and can be from 5 – 900 seconds. The default is 60 seconds.

Changing the FDP hold time

By default, a Brocade ICX 6650 device that receives an FDP update holds the information until one of the following events occurs:

•The device receives a new update.

•180 seconds have passed since receipt of the last update. This is the hold time. Once either of these events occurs, the device discards the update.

To change the FDP hold time, enter the fdp holdtime command at the global CONFIG level of the CLI.

Brocade(config)# fdp holdtime 360

Syntax: [no] fdp holdtime <secs>

The <secs> parameter specifies the number of seconds a Brocade device that receives an FDP update can hold the update before discarding it. You can specify from 10 – 255 seconds. The default is 180 seconds.
