Another dumb question. Router is a Mikrotik RB3011. I need to determine what port a specific MAC address is connected to so I can track down what it is. I have set up MAC reservations on all known devices and still have 3 IP’s (and there MAC addresses that I can not find on my network. Currently only using port 10 going to a switch for all devices (not a smart switch). I am thinking that if I split up to different ports on the 3011 that it might help isolate the area to look. To do that, I need to be able to determine what specific port the IP or MAC address is connected to. Thanks in advance for any help. Bob Ivey
IP>ARP may be your friend here. Very useful unless all your ports are in a bridge.
If ports are bridged, go to Bridge > Hosts in Winbox to see mac address database.
If ports are switched, go to Switch > Host.
In cli:
/interface bridge host print
and
/interface ethernet switch host print
This gets me part of the way there. When I go to Bridge, is shows the different MAC’s going to ether2-master and ether6-master. Port 1 is for the WAN. I see that in the Interfaces menu I can change ports 2 and 6 to none instead of under master port setting instead of ether2-master and ether6-master. Would this approach create any issues or problems and would I then be able to see the exact port that the specific MAC addresses in question are on. Thanks so much for your vary valuable help.
