Hello,
We are using Mikrotik routeros v7.5 netpower 16P(arm) and we face packet drops issue on daily basis which leads to loosing access of the mikrotik.
Our config is really simple with all the ports are in the bridge and RSTP is enabled on the bridge and HW-Offload is also enabled on the ports. Moreover, one management vlan is also part of the bridge.
I went through the STP/RSTP config in this device and the devices connected to it but config is okay and I am unable to understand why we are facing packet drops issue which leads to loosing the mikrotik device’s access.
I monitor logs as well and there are some bridge RX loop packets recorded on ether3 (airfiber 24 antenna is connected) very often but the thing which confuses me is that the occurrence of these bridge loop packets and loosing the mikrotik access are not same. We loose access even when there are no bridge loop packets recorded in the logs.
I would be immensely grateful if any of the experts could guide me in this regards as I am trying to resolve the issue since sometime now.
Please have a look at the logs.
