Interconnections with CDP disabled

Hi all,

We have a Ciscoworks LMS 3.0 implementation with one of our clients, problem is, part of their security policy is to disable CDP on ports. Is their any way we can show the interconnections of devices in Campus Manager with CDP disabled? We have tried Ping Sweep on IP Range as the module setting in discovering devices instead of Cisco Discovery Protocol, but still no interconnections were seen.

Really appreciate your feedback on this. Thanks!

Re: Interconnections with CDP disabled

Sorry, but CDP is integral to CDP's representing an accurate view of the interconnections. This was also noted by Joe Clarke yesterday ("While Campus can still manage device that do not have CDP enabled, the devices will all appear as disconnected on the Topology Map.")

I suggest advocating a change to the security policy. Some organizations have such a policy in place due to the guidance in an NSA hardening document that advocates disabling CDP for security purposes. The context of that recommendations, however, was for publicly accessible networks. If your devices are properly firewalled or otherwise shielded/disconnected for public access, running CDP should not be a problem. It will allow you to exploit the full functionality of Campus Manager, among other things.

Hope this helps. Please rate this post if it does.
