Foundry Discovery Protocol (FDP) and Cisco Discovery
Protocol (CDP) Packets
Table 77 lists individual Brocade switches and the discovery protocols they support. These features
are supported in the Layer 2, base Layer 3, edge Layer 3, and full Layer 3 software images, except
where explicitly noted.
FDP Overview
The Foundry Discovery Protocol (FDP) enables Brocade devices to advertise themselves to other
Brocade devices on the network. When you enable FDP on a Brocade 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 Brocade device running FDP sends FDP updates on Layer 2 to MAC address 01-E0-52-CC-CC-CC.
Other Brocade devices listening on that address receive the updates and can display the
information in the updates. Brocade devices can send and receive FDP updates on Ethernet
interfaces.
FDP is disabled by default.
NOTE
If FDP is not enabled on a Brocade 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.
