RX Drop on ether1 (RB850gx2)

RouterOS General

Hi,

I’m seeing weird RX packet drop on ether1 when ehter1 is removed from switch chip (switch all ports=false).

Plugging ether1 to switch chip (switch all ports=true) stops the RX drop.

These packet drops doesnt affect cpu nor RAM usage, also network seems to be stable.

Any idea what that might be or is this normal with rb850gx2?

So what is your traffic speed and what is your CPU usage? It sounds like the bandwidth of your traffic may be overwhelming the CPU, whereas when it is offloaded through the switch chip, it works fine.

Hi,

My traffic is pretty low, I have set up for one vlan=6 passthrough from ether1 to ether5 using bridges, and it is usually about 15Mbps (IPTV). This is also happening even when traffic is super low, 1Mbps. CPU usage is also low, 1-3% max.

Today I’ve reseted configuration and tested, same thing happening. Almost 0 traffic but RX Drops counter on WAN spinnig if I remove it from switch
