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.
Enabling Interception of CDP Packets Globally
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:
HP 9300 series(config)# int e 2/1
HP 9300 series(config-if-2/1)# cdp enable
Syntax: HP 9300 seriesHP 9300 series[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:
•
Cisco neighbors
•
CDP entries for all Cisco neighbors or a specific neighbor
•
CDP packet statistics
Displaying Neighbors
To display the Cisco neighbors the HP device has learned from CDP packets, enter the following command:
HP9300# show fdp neighbors
