i am getting output drops on switch actually i have ethercannel bundleing 4 ports and those are connecting to our hyperV server. We have schedule mirror images to one of our another server everyday So whenever transfer start we get alert from our Opmanager that discard rates of interface reaching to 80% File transfer is quite big i have checked interface cournters and i see output drops is also too high
here are some show commands results
