  • 1.  IAP 215 Reboots After Failed Attempt To Take Over The Master Role

    Posted Feb 27, 2020 12:02 PM

    Hello everyone,

     

    I have a cluster of 35  IAP 215's. They use a virtual controller and one AP is set via the "Preferred Master" setting. They are currently on 8.5.0.6_74058 firmware. This problem has been happening for about a month now and I have run out of ideas.

     

    This is the string of errors that happen leading up to the misbehaving AP reboot.

     

    To add some context to the posted log. RM-26-Ceiling is NOT supposed to be the master its RM-01

     

    Error Log:

    The show ver command always shows this entry:

     

    Reboot Time and Cause: AP rebooted Thu Feb 27 00:30:41 UTC 2020; System cmd at uptime 0D 0H 4M 56S: Preempted by provisioned master (b4:5d:50:c0:77:1c 10.23.1.81) uptime from boot: 4 minutes 55 seconds; uptime from being master: 40 seconds

     

    I have tried downgrading to the 6.5 firmware train to see if it was a problem with the firmware. That was not the case.

     

    I have factory reset the AP and added back into the cluster along with outright replacing it. I tested all physical variables, wiring, placement, switch port. The APs are connected to Cisco Catalyst Switches. There has been no power interruptions from the PoE side of things either.

     

    I hope this is enough information to work with. Thanks in advance.

    Can you check the IP of the offending AP, and see if it is the same as the VC IP? This may cause issues.

    The IP of the offending AP is different than the VC. Both are static reservations.

    Hi, I was wondering if you'd managed to find a resolution to this issue? I'm encountering a similar issue so just thought i'd check.

    Many thanks
