features are supported in full Layer 3 software images, except where explicitly noted.
FDP Overview
The Foundry Discovery Protocol (FDP) enables Brocade ICX 6650 devices to advertise themselves
to other Brocade devices on the network. When you enable FDP on a Brocade ICX 6650 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 ICX 6650 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.
