I'm seeing a ridiculous amount of Xmit errors on a port that are showing up as Excess Defer frames:

Deferred frames are called out as:
The issue is because the traffic load destined for the switch is excessive and causes the frames to be discarded. Normally the deferred frames are the number of frames that have been transmitted successfully after waiting for the media, because the media was busy. This is usually seen in half duplex environments where the carrier is already in use when it tries to transmit a frame. But in full duplex environments the issue occurs when the excessive load is destined for the switch.
Would switchport nonegotiate cause this issue, or is there something else I should be looking for? I can't seem to find much information on this specific error.
