Reading CDP packets

Clearing FDP and CDP statistics

To clear FDP and CDP statistics, enter the following command.

TurboIron#clear fdp counters

Syntax: clear fdp counters

Reading CDP packets

Cisco Discovery Protocol (CDP) packets are used by Cisco devices to advertise themselves to other
Cisco devices. By default, devices forward these packets without examining their contents. You
can configure a device to intercept and display the contents of CDP packets. This feature is useful
for learning device and interface information for Cisco devices in the network.

Devices support intercepting and interpreting CDP version 1 and version 2 packets.

NOTE

The Brocade device can interpret only the information fields that are common to both CDP version
1 and CDP version 2.

NOTE

When you enable interception of CDP packets, the Brocade device drops the packets. As a result,
Cisco devices will no longer receive the packets.

Enabling interception of CDP packets globally

To enable the device to intercept and display CDP packets, enter the following command at the
global CONFIG level of the CLI.

TurboIron(config)#cdp run

Syntax: [no] cdp run

The feature is disabled by default.

Enabling interception of CDP packets on an interface

You can disable and enable CDP at the interface level.

You can enter commands such as the following.

TurboIron(config)#int e 1

TurboIron(config-if-1)#cdp enable

Syntax: [no] cdp enable

By default, the feature is enabled on an interface once CDP is enabled on the device.

Displaying CDP information

You can display the following CDP information:
