Enabling the Foundry Discovery Protocol (FDP) and Reading
Cisco Discovery Protocol (CDP) Packets

In this chapter

This chapter discusses the Discovery Protocol (FDP) – a protocol used by Brocade devices to
advertise themselves to other Brocade devices, and Cisco Discovery Protocol (CDP) – a protocol
used by Cisco devices to advertise themselves to other Cisco devices. Brocade devices use this
protocol to learn device and interface information for Cisco devices in the network.

Using FDP

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:
•
•
•
•
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.
FDP is disabled by default.
NOTE
If FDP is not enabled on a BigIron RX 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 Brocade device to globally send FDP packets, enter the following command at the
global CONFIG level of the CLI.
BigIron RX(config)# fdp run
Syntax: [no] fdp run
