I contacted Mikrotik support and they agreed this issue. Promised to fix it in next updates.

Hello!

I think i have the same issue. At the moment you activate vlan you can't see any romon clients. I have seen this since more firmeware versions..

Same problem with Switches CRS326/328 !!!
Romon stopped passing through vlans via trunk ports
It does not work with this

but it does work with this

I have tried/tested it on the several different networks. I see that problem only on the switches CRS 3xx series.
And it was working fine on RouterOS 6

After upgrading from 6.49.5 to 7.2 almost all neighbours on RoMon list disappeared. In our environment there are almost 100 devices and we can see only 10 of them. Ingress filtering is unchecked and frame types is set to admit all. It worked fine before the update. Any help would be appreciated.

This is a bug in the latest firmwares that caused if you have admin defined mac address for bridge.
In this case you need to manually define the ID RoMON parameter, which must be equal to the MAC address of any ethernet port (even if not connected).
I got this idea from viewtopic.php?t=181936#p904664

I have the same problem, but setting RoMON ID didn't help. The only solution I have found is to use hybrid ports between switches - it seems like RoMON (and also Neighbors Discovery) frames are sent as untagged.
