Could you do a network capture on the ubuntu? tcpdump -i YOUR_INTERRACE -s 1500 -w dump.pcap and then try both with and without -n in mactelnet in another terminal. And give me the dump file?

Hello, based on your suggestion, I performed network capture on Ubuntu and executed the 'mactelnet' command

dump.zip

Only a Mikrotik hosted on a VMWare is present on that interface it seems. Are you sure this is captured from the correct interface where the RB952Ui whould be? The mikrotik neither answers any packets for d4:01:c3:78:f0:53 or announces itself on the network with either cdp, lldp or mndp like the vmware does. So it seems like this is on another network interface.
