I have a strange situation on one of my customer´s Data Centers:
There are some servers connected to a C6509 switch via GigabitEthernet links set up at 1000/FD. I have observed the next difference regarding the throughput:
- If flow-control is disabled on both the switch ports and server ports the maximum throughput is 200Mbps.
- If flow-control is enabled on both the switch ports and server ports the maximum throughput is 900Mpbs.
Taking in count there are no capacity/congestion problems on the switch and all the ports are error free and they have no packet drops, is there any reason why this difference exist?
