2100 switch port counters?
-
HI
Is there any way to diagnose if a sg-2100 switchport is dropping TX packets? Cli commands to see stats for all switch ports fx?
I have noticed that doing an iPerf test transmitting from a remote Gbit host to a 100Mbit client on a sg-2100 port, results in lots of retries and I can't get it to max out 100Mbit throughput.
Since the speed stepdown will require the switch to buffer quite a few packets in a 128Kb iPerf TCP session, I was wondering if the Built in marvell switch cannot handle that and drops the packets?

Not from the switch chip directly. The only access to it is via
etherswitchcfgwhich doesnt show that information.Technically you can read/write the switch registers directly using that but you'd need to know exactly what to read.
Maybe a flow control mismatch?

@stephenw10 Thanks for clarifying. I'll look into flow control again, but I could not change the results by enabling/disabling it on the client.
Since I cannot modify flow control in the switch I have very little control. -
Does the 2100 switch correctly show it's linked at 100M?

@stephenw10 Yes
