Overruns on CSS326-24G-2S+RM

Thu Nov 02, 2017 12:24 pm

Rx Overruns on CSS326-24G-2S+RM > 1000 for 1 hour on the uplink port. Traffic is a maximum of 40Mbps on this port. On other ports, traffic is less than 3Mbps and it is all going to the uplink port (all computers work only with the Internet - they do not communicate with each other).
Can the frame buffer size not be enough? What is the frame buffer size? The characteristics are not indicated. Can it be without a buffer?
In the test results, the throughput is 33-43Gbps depending on the size of the packets.
That is 1000 times more than in our mode of operation. Why appear Rx Overruns I do not understand.

I got the same problem! rx-overruns on the trunk port
i'm running with the latest version (2.7)



Example:
The trunk port is running at 1G full duplex connected to a RB1100Dx4
i'm connected direct to a random port running at 100Mbps
if i ran a btest from another device on a different port running at 100Mbps
on my device... i cant get more than 2Mbps

i tried with flow-control on and off
same thing..
