Installation and Basic Configuration Guide
NOTE: When you enable interception of CDP packets, the HP device drops the packets. As a result, Cisco
devices will no longer receive the packets.

To enable the HP device to intercept and display CDP packets, enter the following command at the global
CONFIG level of the CLI:
HP9300(config)# cdp run
Syntax: [no] cdp run
The feature is disabled by default.

Enabling Interception of CDP Packets on an Interface

Starting with software release 07.6.04, you can disable and enable CDP at the interface level.
You can enter commands such as the following:
