    Our speaker Sajin was kind enough to also share the AirMatch troubleshooting commands listed in the webinar- access them below or share the attached document with your teams/ colleagues:

     

     

    Troubleshooting commands:

    ========================

     

     

     

     

    Enable debugging:

    ===============

     

    (ArubaMM) *[mynode] #configure t

    Enter Configuration commands, one per line. End with CNTL/Z

     

    (ArubaMM) *[mynode] (config) #logging system level debugging
