Using FDP
2
NOTE
FDP is not supported on VPLS/VLL endpoints. By removing FDP from the configuration, the no fdp
enable will stay in the configuration.
Changing the FDP update timer
By default, a device enabled for FDP sends an FDP update every 60 seconds. You can change the
update timer to a value from 5 – 900 seconds.
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 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 a command such as the following at the global CONFIG level of
the CLI.
Brocade(config)# fdp holdtime 255
Syntax: [no] fdp holdtime secs
The secs parameter specifies the number of seconds a 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.
Displaying FDP information
You can display the following FDP information:
• FDP entries for neighbors
• FDP entries for individual devices
• FDP information for an interface on the device you are managing
• FDP packet statistics
NOTE
If the device has intercepted CDP updates, the CDP information is also displayed.
