collision counter

RouterOS General
1

Hi,

I’ve performance issues with RB500 routing 2 Ethernet Segments.
I assume it has to do with collisions. But I cant find a counter
or indication in ROS. The switch is dumb so no numbers too.

Any hints where to find collision counter?

There are no collisions on full duplex ethernet.

You can query the snmp for the NIC to get the error counts and other useful data though. Typically a auto-negotiation issue will cause certain problems, fixing them at 100 full to see if that helps.

There are however, things like CRC Errors, Frame Errors, etc etc etc…

I’d definately second a call for counters inside MT…

The stats are there, they just aren’t accessable outside of snmp.
