I have a trunk that is showing output drops more in one side than the other. What could be the cause?
Here is what I did but without much success:
1. Change the cable...now only one side was dropping packets.
2. Moved the trunk to a different port on both switches, still one side was dropping packets.
3. Disconnected the cable to only use one trunk because they were two trunks. Now the original side that was dropping more packets is dropping.
So the problem is not limited to one switch. Help!!!
4. I rebooted one switch but the problem still there.
One thing that will say is that the packets are being dropped on the forwarding port in the STP. I tried to only allowed some specific VLAN but without much success.
