Neighbors only works when is connected to my machine / router. The device with damaged label is in the tower and can't be removed. I can access the device remotely only via Winbox / browser. Wireshark don't work here. Any idea?Can you see that mac in Winbox -> Neighbors -> Refresh ???
Also Wireshark should helps
Nope. It works if you have L2 connection, no matter how far you are. Same for mac telnet. If your traceroute shows 0 hops between your pc and device - it is L2 connection. if you have access to every single device between you and router - you can create your own vlan or EoIP/VPLS tunnel and get L2 connection between your PC and your router.
