We have been seeing "pause output" on our 6509 interfaces on devices that have high traffic throughput.
I have seen two different descriptions of waht is telling the source port to pause.
My understanding is that the device that has the pause output is trying to send traffic to a device that has full buffers or is congested and the target end is telling the port to pause sending traffic.
The question is , what is telling the source port to pause, is it the 6509 port that the target device is connect to, or is it the target device itself?
enabling flow control is a possible workaound for those linecards like some 48GE linecards also on C6500 that have a ratio 8:1 n:1 in general where not all ports can be line rate at the same time (the ports share the same ASIC hardware resource)
If anyone can answer these questions, I too would love to see them. I am having a lot of PAUSE output notices on an otherwise unconfigured port that is connected to my SAN and servers. I am getting high latentcy on those same servers. I think these answers would help me out a lot with my own troubleshooting.
