CDP packets
Cisco Discovery Protocol (CDP) packets are used by Cisco devices to advertise themselves to other
Cisco devices. By default, Brocade devices forward these packets without examining their
contents. You can configure a Brocade 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.
Brocade 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.
Brocade(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.
Brocade(config)# interface ethernet 1/1/1
Brocade(config-if-e10000-1/1/1)# cdp enable
Syntax: [no] cdp enable
By default, the feature is enabled on an interface once CDP is enabled on the device.
