Enabling the Foundry Discovery Protocol (FDP) and Reading
Cisco Discovery Protocol (CDP) Packets
Table 117 lists individual Dell PowerConnect switches and the discovery protocols they support.
Using FDP
The Foundry Discovery Protocol (FDP) enables Dell PowerConnect devices to advertise themselves
to other Dell PowerConnect devices on the network. When you enable FDP on a Dell PowerConnect
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 Dell PowerConnect device running FDP sends FDP updates on Layer 2 to MAC address
01-E0-52-CC-CC-CC. Other Dell PowerConnect devices listening on that address receive the
updates and can display the information in the updates. Dell PowerConnect devices can send and
receive FDP updates on Ethernet interfaces.
FDP is disabled by default.
NOTE
If FDP is not enabled on a Dell PowerConnect 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 Dell PowerConnect device to globally send FDP packets, enter the following command
at the global CONFIG level of the CLI.
