Could someone explain what happens to a network flow that encounters an output overrun?
I had a report of a file copy between 2 servers in the same 6509 chassis was slow over the weekend. It took 14 hours to copy where it usually takes 4. I see that there are 32 overruns with 10 queue drops. It looks like this is a case where the NIC on the server couldn't keep up but what effect does that have on the overall network performance? Does flow control start chopping the window size? Is 32 a high number?
Thanks in advance,
