850E and cnMatrix

Has anyone else experienced an issue with a remote end of the 850E and cnMatrix TX2012 switches port keeping going up and down? I have one that keeps doing this. it will be fine for weeks then all of a sudden it will go up and down for days on end. I am running version 11.9.0.0.0.320 on the PTP850e and 4.1.3-r1 on the TX Switch.

We’re using a PTP850e with a TX2020R-P without issues. Sounds like maybe there’s a cabling issue? Is it collocated near high power FM radio? ALSO, take a look at the attached guide and make sure that you’re using the right settings and bank on your switch.
