Message of the Day: Every day is a lesson!
I just found that show cdp entry command supports wildcard search. I am a frequent user of this command, and it usually happens when I first execute show cdp neighbors to find a neighbor of interest, followed by a show cdp entry <name> to find its management IP address. I usually copy/paste the full name of the neighbor, until just now. A short example will tell you the rest…
