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.
