Enabling the FDP and Reading Cisco Discovery

Using FDP

FDP enables HP Routing Switches to advertise themselves to other HP Routing Switches on the network. When
you enable FDP on an HP device, the device periodically advertises information including the following:
• Hostname (device ID)
• Product platform and capability
• Software version
• VLAN and Layer 3 protocol address information for the port sending the update. IP, IPX, and AppleTalk
Layer 3 information is supported.
An HP device running FDP sends FDP updates on Layer 2 to MAC address 01-E0-52-CC-CC-CC. Other HP
devices listening on that address receive the updates and can display the information in the updates. HP devices
can send and receive FDP updates on Ethernet.
FDP is disabled by default.
NOTE: If FDP is not enabled on an HP device that receives an FDP update or the device is running a software
release that does not support FDP, the update passes through the device at Layer 2.

Configuring FDP

The following sections describe how to enable FDP and how to change the FDP update and hold timers.
Enabling FDP Globally
To enable an HP device to globally send FDP packets, enter the following command at the global CONFIG level of
the CLI:
HP9300(config)# fdp run
Syntax: [no] fdp run
The feature is disabled by default.
Enabling FDP at the Interface Level
Starting in software release 07.6.04, you can enable FDP at the interface level by entering commands such as the
following:
HP9300(config)# int e 2/1
