I upgraded my CRS125 switch from 6.37.5 to 6.39.2 and the vlan I have on it stops working. I can no longer see layer 2 neighbours either. If i downgrade back to 6.37.5 the vlan works again and I can see devices on that vlan in neighbours again. Anybody know how to fix this please?
I had same problem on 6.38.5 and if VLAN on bridge disable RSTP. on 6.39.2 not see any problem.
