Debugs/Show cli's/Control path captures to figure out failed association attempts from the APs

  • 1.  Debugs/Show cli's/Control path captures to figure out failed association attempts from the APs

    Posted Jan 22, 2017 03:44 AM

    Dear Folks,


    Are there any handy debugs/cli's or the control path packet captures that could be enabled in Aruba Controller that helps us list out the APs that are having failed attempts to register with the controller and the reason for failed association?


    In my network, few of the APs successfully gets IP address but they fail to register with the controller. Need to find out the ways to conclude after obtaining an IP address, where the discovery request from these APs are even reaching the controller and the associated debugs to interpret the reason of failed association.

     

    Best Regards,

    Adnan

    What discovery method are you using for the AP to reach the controller?  Typically you want to connect to the AP's console port and watch the bootup cycle..

    Thanks Joseph,

    Consoling the AP is not a feasible option as the AP is mounted at high height.

     

    I am using the default discovery method, "Host-Controller name", PFA.

    Do you have a DNS a-record defined for aruba-master.<your domain>?

    Is the DHCP server that is providing ip addresses to the subnet your AP is on providing the domain field?
