Enabling the Foundry Discovery Protocol and Reading Cisco
Discovery Protocol Packets
Using FDP
The Foundry Discovery Protocol (FDP) enables Dell devices to advertise themselves to other
devices on the network. When you enable FDP on a 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.
A device running FDP sends FDP updates on Layer 2 to MAC address 01-E0-52-CC-CC-CC. Other
devices listening on that address receive the updates and can display the information in the
updates. Devices can send and receive FDP updates on Ethernet interfaces.
FDP is disabled by default.
NOTE
If FDP is not enabled on a 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 a device to globally send FDP packets, enter the following command at the global
CONFIG level of the CLI.
PowerConnect(config)# fdp run
Syntax: [no] fdp run
The feature is disabled by default.
Enabling FDP at the interface level
By default, FDP is enabled at the interface level after FDP is enabled on the device.
When FDP is enabled globally, you can disable and re-enable FDP on individual ports.
Disable FDP by entering commands such as the following:
PowerConnect(config)# int e 1
