Hi!
I'm running some ping monitoring from my CRS106 and I see some pings are dropping. When I see these drops they are on several devices not just one and the devices themselves that go through the CRS does not experience any drops. So I started to think these drops are caused inside the CRS.
To confirm this I disabled hardware offload on the bridge ports forcing traffic into the CPU with the bridge working in software mode (this is low throughput anyway, about 50kbit/s through the switch) and now I get drops even on the traffic through the switch. For me this seems to confirming the dropps happen between switch chip and CPU? Routeros 7.8 but I had this problem for a while so it is not connected to this very latest version.
Any idea why this happens?
