RB433AH - Packet loss on bridge-interface

Patrick987 · December 23, 2008, 3:24pm

Hello @ all,

I have a RB433AH, newest firmware 2.18 and RouterOS v3.17 installed. I added ether2 and ether3 to the brigde that i created earlyer. Now I connected the RB433AH in the uplink channel of our XDSL serverroom. there are around 150 users online and produce at the moment a traffic of around 5 to 10Mbits with 500 too 1000 packets per second.
The Problem is, that a lot packet losses are now on the line. without mikrotik ther are 0%. I do nothing else, no mangle and firewalling yet.

any suggestions what i can do? Have you had also such problems in the past?

thanks a lot for your reply,
Patrick

Enable RSTP on all bridges in the network and assign admin-mac to the bridge manually from one of the bridge ports.

It is possible that packet loss happen because of mac-address change or some loop.
