For some time, the main problem in my network is the situation like in the attached image.
GSP uptime: about 100d.
reboot, changing settings on the QRT ethernet does nothing. (but ethernet is UP 1Gbit/s)
Changing the power settings on GSP (auto/always on) - nothing.
It is necessary to physically reboot everything.
The first time I noticed the situations when I started to deploy QRT+GSP.
I used to happened occasionally 2-3 times a month
But this week I had such a situation in 3 different points.
If replace gsp with hex POE everything goes back to normal.
