This will sound stupid and I'm probably missing something obvious. I'm mapping a very old segment for my company for moving the segment to a new location.
Using a combination of MAC-add tables and arp tables, I have found all the connections...except two.
They have mac addresses very similar to each other and I believe they are for old equipment that hasn't been there for two years or more. When I search the configs of the devices, one f them has the ip for that device.
Shouldn't that ip and mac have disappeared by now? I tried pinging the IP and it doesn't respond (but then again, it could have been an old ASA.
I'm baffled. Any ideas? Thanks Joe W
