I have a pair of 5548UP Nexus switches connected to a 2232PP FEX. Some of the FEX ports are connected to HP Flex Fabric modules, and I'm seeing lots of "TX pause" frames. Can anyone explain exactly what this counter means? Is my FEX telling the connected device to pause their transmission, or does this mean that the connected device is sending pause frames to my FEX telling the FEX to pause?
