I know 3 applications for the CDP protocol:

1.

You can use the 'show cdp neighbors' to see what devices are connected to your local device and what are the local and remote ports.

The 'show cdp neighbor detail' command will also display an ip address from the neighbor. You can use it to telnet to the neighbor devices.

This way you can discover your network without physically seeing it.

2. Cisco switches discover Cisco IP phones connected to the switch using the CDP protocol. Switches then make a decision about CoS trusting depending on the configuration of the specific switch port.

3. You can use CDP to configure On-demand routing (ODR) in simple hub-and spoke topologies.

Hi,

What application / scription language you are using for accessing the Cisco device for running the commands?

OR to rephrase the question... how is your application connecting to the cisco device.
