Displaying Fdp Information - HP ProCurve 9304M Installation And Configuration Manual

Installation and Basic Configuration Guide
HP9300(config-if-2/1)# fdp enable
Syntax: HP9300HP9300[no] fdp enable
By default, the feature is enabled on an interface once FDP is enabled on the device.
Changing the FDP Update Timer
By default, an HP 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:
HP9300(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, an HP 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:
HP9300(config)# fdp holdtime 360
Syntax: [no] fdp holdtime <secs>
The <secs> parameter specifies the number of seconds an HP 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.
