Hi NHFarmer, I face the same problem since monday on different sites. Just recognized that this error is just showing up on switches with the current firmware MS 17.2.1.1 and not on switches with MS 16.9. But i can not see any real problems. All information seems to be ok.  Also no problems in the old view. Edit: also got the problems now on MS 16.9, so it looks like a GUI bug. Best regards René ... View more

Hi, I just want to give a short feedback on my first update results. I updated the last days 44 switches from 16.9 to 17.2.1. Most of them are MS225 and some MS120. In general everything was running smoothly except of one MS225. Uplink on SFP ports was not working any more and the stacking ports were also not working. Could not bring the switch online again, so i did a reset but still the sfp ports and stacking ports are not working.  Switch is now connected via a copper port which is working well and case is already created. Maybe it is related to following open topic, but not sure: In rare circumstances MS225 switches may encounter a software crash that results in a reboot Just for your information, if you face similar problems.
