Additional notes
Disable flow control on the devices at each end of the link.

If the above is not possible,  please note:

Disabling flowcontrol does not stop pause frames.

If there is a port with a pauseframe issue and you want to try and stop the pauseframes, you need to run the command
clear port advertise port.x.x pause
A warning, if you run this command on a up link port then there will be a topology change
