Reading CDP 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 BigIron RX drops the packets. As a result, Cisco
devices will no longer receive the packets.

Enabling interception of CDP packets globally

To enable the BigIron RX to intercept and display CDP packets, enter the following command at the
global CONFIG level of the CLI.
BigIron RX(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.
BigIron RX(config)# int e 2/1
BigIron RX(config-if-e10000-2/1)# cdp enable
Syntax: [no] cdp enable
By default, the feature is enabled on an interface once CDP is enabled on the device.
