Dear patacca,

First, thank you for running a relay!

Second, great advice from fatal here:

I will add:  You are seeing some frame errors, which could point to a
bad cable or switch port.  I would contact the provider and ask them
two things:

1. What is the duplex setting on the switch port?  Full?  Auto?  Half?
 If they are willing to hard-set it to full, which you then mimic on
your end, all the better.

2. Are they seeing errors on input or output on the switch port?  If
so, ask them to replace the cable.  If that doesn't do it, ask them to
move you to a new switch port.

Good luck!

Be well,
Rabbi Rob.
