Hi, On pg 178 of http://public.dhe.ibm.com/software/dw/linux390/docu/les3dd03.pdf there is a section on using tcpdump or wireshark to do traces on the hypersocket . That said, As others have explained it is not likely an issue unless you are seeing huge amount of Tx errors as I understand it.
Hope that helps, Peter PS It is SUSE now :-) SuSE was an artifact of an obscure German law, which is now no longer in effect.... for 10 years now. I won't bore the list with the gory details ;-) >>> Ron Foster <ron.fos...@baldor.abb.com> 7/25/2013 6:18 AM >>> Carsten, Do you know where I would start looking for causes of the transmit errors on Hipersockets? The error is occurring on SLES11 SP2 systems. We are not having it on our SLES10 SP4 systems. Do I need to open a problem with the SuSe folks?

Ah, you're right - that would be accouned as dropped, not TX error. Forget about my reply then, time to look at other causes for that TX error.
