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.

• FDP entries for Brocade neighbors
• Individual FDP entries
• FDP information for an interface on the device you are managing
