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 00-00-00-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.
