  • 1.  IAPs reboot after master election

    Posted Nov 21, 2019 08:18 AM

    Hi,

     

    I have noticed something... sometimes, IAPs reboot after master election:

    Another IAP, the same day:

     

    Nov 20 16:23:53 KERNEL(AP-7628@172.31.16.13): [ 49.860637] ip_time_handler: Got ip and packets on bond0 Started master election 149-0, rand 17

    I don't understand the "power loss" message, there is no errors on the switch (HP 5130 PoE HI).

    On the switch, cable test is ok on both:

     

    [SW-02-GigabitEthernet3/0/7]virtual-cable-test
    Cable status: normal, 45 metre(s)

    [SW-02-GigabitEthernet3/0/8]virtual-cable-test
    Cable status: normal, 72 metre(s)

     

    I'm running firmware 6.5.4.13 (MODEL: 315).

     

    Can you help me?

     

    Thank you

    it looks like a power loss but perhaps it is better to use the the newer Instant firmware versin like 8.3.0.10 if you only have IAP-315s, your version is very old.

    Hi Ariyap,

     

    I also have IAP-305. Should I upgrade with the lastest version 8.6.0.0 ?

    I have updated IAP with 8.6.0.0 but I still have the problem.
