Re: Technical Webinar- Recording + Slides - What does AirMatch do differently?

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
