Airwave automatic controller reboots when SNMP Down

Hi all,

 

i've got an issue where i think Airwave is rebooting my controllers when it fails to poll the device using SNMP. Is there something i can turn off in airwave to prevent this occuring?

 

This is my controller log:

 

Oct 3 11:13:25 :315382:  <CRIT> |fpapps|  Reboot Cause: User reboot.

 

This is my airwave log:

 

Thu Oct  3 11:17:57 2013SystemUp
Thu Oct  3 11:17:56 2013SystemDevice rebooted while marked as down: Device uptime value changed (current: 5 mins 28 secs, calculated: 18 hrs 46 mins 5 secs)
Thu Oct  3 11:13:10 2013SystemStatus changed to 'ICMP ping failed (after SNMP get failed)'
Thu Oct  3 11:13:10 2013SystemDown
Thu Oct  3 11:12:08 2013System

Error in SNMP polling: Timeout(thin_ap_status)

Are you managing the controller using Airwave ? but of course even in that case that shouldn't happen .

 

 

Thank you

Re: Airwave automatic controller reboots when SNMP Down

The log just shows that the controller was down due to no snmp response, then confirmed down due to no ping, and then when the controller came up, AMP reports that the controller had rebooted due to the change in uptime.  This is not the same as AirWave sending a reboot command to the controller.  To verify the behavior, check the device logs in /var/log/ap/<id of controller>.  There should be an event log that is the same as what you included originally, and then the audit log (used during config audits), and then a telnet_cmds log which would have any reboot command.

 

For instance, my controller's URL:

http://robs_amp/ap_monitoring?id=1234

this corresponds to CLI directory: /var/log/ap/1234

 

# cd /var/log/ap/1234

# grep -i reboot *

event.log:Tue Oct 1 12:09:24 2013 Device has rebooted: Device uptime value changed (current: 3 mins 52 secs, calculated: 5 days 14 hrs 18 mins 12 secs) System

 

This tells me that my controller had rebooted, but it was not initialized by AMP since I didn't see the reboot command in the outgoing telnet_cmds log.

Re: Airwave automatic controller reboots when SNMP Down

Thanks everyone, looks like i'd misunderstood what was happening.

 

no commands were sent to the controller.
