Changing the FDP update timer
By default, a Brocade 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.
device(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 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.
device(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.
Displaying FDP information
You can display the following Foundry Discovery Protocol (FDP) information:
• FDP entries for Brocade neighbors
• Individual FDP entries
• FDP information for an interface on the device you are managing
• FDP packet statistics
NOTE
If the Brocade device has intercepted CDP updates, then the CDP information is also displayed.
Displaying neighbor information
To display a summary list of all the Brocade neighbors that have sent FDP updates to this Brocade
device, enter the show fdp neighbor command.
device# show fdp neighbor
