Hi,
I have a question regarding accesspoints changing controllers and rebooting.
2 times this month we have recieved alerts that a number of accesspoints(arround 50-60 out of 1700) have gone offline, rebooted and sometimes changed controller from Master to Local.
After a while they all return to normal. We have a 2 WLC (master and local) setup with arround 1700 accesspoints. We fail to find a reasson to this behaviour. No other network equipment experience any issues during these brief episodes.
Some of the alerts in Airwave looks like this:
Aruba AP 105 XXXXXXXX AP's associated controller is changed from XXXX-ARUBA-MASTER-7240 to XXXXX-ARUBA-LOCAL01-7240
The timeline is:
1st a log that says the AP changed Controller
then a log that says the AP is up
and then lastly a log saying that the AP is status "OK".
Any input is apreciated. Thank you.
