What the deal with my CDPs

[ase2dais]

Hello Forum !

Initially my first config, CDP neighbors was working.
during the course of time, for security reason, I did a
"no cdp run" on it.

I enable it back with "cdp run" and my cdp neighbors is showing incomplete.

Make sure that you have CDP enabled on teh interfaces..

Sometimes when you do the &quot;no cdp run&quot; it also applies a command to your interfaces..
