Need solution for topic title. Have CCR1009 router but with such issue. Routeros 6.37.1 and firmware 3.33. Did upgrade to 6.37.2 but same problem.Cant use these group of ports as after some time period they just decide to not let traffic pass thru.
I’ve seen the same on a CRS125-24G-1S recently, this was fixed after a configuration reset (I suspect the /switch configuration was changed in a previous ROS version and did not get updated properly when upgrading).
