Aruba AP 105s failing to communicate with the controller

  • 1.  Aruba AP 105s failing to communicate with the controller

    Posted Apr 17, 2015 11:04 AM

    2 Aruba 105s are unable to reach the controller anymore (ArubaOS Version 6.3.1.13).

    Both power and ethernet lights are green, radio lights not coming on - the Power led is blinking red after a few minutes due to rebooting. It has been working for just under a year but suddenly failing for both APs. Using it on POE, and verfified that the switch is working. Tested both APs in another building and both work fine.They have been disconnected from the ethernet port and reconnected but still unable to reach the controller, any ideas?

     

    Thanks...

    You really need to get a console cable connected to them to see the messages on bootup. You can also escape out of the boot process immediately and run the dhcp command to make sure it is getting a proper IP address.

    On the controller side of things run the following command and it may show what's going on :
    show log system 100

    Pull network cable out of one of the APs and plug it into your laptop. Do you get an IP address? Is it in the correct VLAN?

     

    Cheers

    Problem resolved, there was an issue with one of the switches that indirectly connects which lost connectivity via snmp. Fixed via a cold restart

    It was a neighbouring switch device which was not sending snmp traffic...It was restarted which resolved the issue
