Aruba 5412R zl2 is restarting - Reason for system reboot: Watchdog reset

    Posted Sep 03, 2017 11:27 AM

    Hi,

     

    I have an Aruba 5412R zl2 switch. For the last two days, the switch reboots about every 8 hours. It has two management modules, but the issue exists with either of them connected or with both of them connected. After each reboot the log shows something like this:

     

    I 09/02/17 11:15:30 00062 system: AM1: System went down without saving crash information
    I 09/02/17 11:15:30 03006 system: AM1: Reason for system reboot: Watchdog reset
     
    Is there any possibility to disable the watchdog to avoid the restart?
     
    Thank you,
    Florin

    A watchdog is something that checks the functioning of your system, and restart the system when components stop responding (properly). This is done in the hope that after a restart, things will be better.

     

    Restarts due to watchdog timeout indicate a serious issue with your hardware/software. And periodic watchdog issues should be investigated by Techsupport.

     

    Please contact Aruba Techsupport/TAC. Contact details are in my signature.

    I did that, but they are moving slowly. Until then, I am trying to disable this watchdog. So, is there any possibility to do this?

    I'm not sure on that; TAC should be able to help you with that question for a workaround.

     

    If you believe TAC should be moving quicker, feel free to use the escalation procedure described here, as having a network interruption every 8 hours seems unacceptable to me.

    Was this ever resolved?  Our brand new 5412R is throwing several Watchdog Reset errors and subsequent management Module failover.  Did you have a bad media module (SFP or Ethernet)  Support has no idea why it's malfunctioning.   We have another 5412R in our environment...same firmware and modules...works perfect!  Extremely frustrating...

    This happened to one of my switches as well, but i don't have redundant management modules. first time occurrence. 

     

    running 16.08.0006. will probably attempt an update to 16.10

    I meant to post this a little while ago, but the root cause for the WDR's is a 5400R Series switch running with routing enabled and also running ip directed-broadcast.  As soon as ip directed-broadcast was disabled, the WDR's stopped.  Aruba is hoping to have this bug resolved in the upcoming firmware update in the month of June or early July.  Hope that helps.
