Thank you for sharing this info.
In the last two days it occurred on about 10 AP's overall. Question
: Is anything common between these AP's, like same POE switch, same location, subnet etc? Have these APs rebooted more than once since upgrade?
Our switches does support 802.3 atQuestion
: Have you seen any fluctuation in the power budget.
I can set up a test zone, but we need the new version for our R730Answer
: vSZ allows us to create multiple zones and in case you have upgraded the vSZ (as you did), it allows us to choose different firmware versions for each zone.
I have checked internally and there are no such issues reported of AP reboot due to power cycle. So best way to investigate is to move these AP's to the older version and monitor their behavior. And if they run stable, then you can open a support case to investigate this further.
