Wireless Access

At the end of the "show ap association ap-group XXXXXX"  You get an output of "Band steer moves (T/S).  What does the output mean (T/S)?  Example :  996/779

Why are you doing 80mhz channels?  I know it is the default, but....

I am using the 80 because it is on by default.  What should I be doing? And how do I change it?  I do have a very dense deployment not by my choice.  Is there some documentation I can read?

In your ARM profile, you should change the "Allowed Bands for 40mhz channels" to "None" and uncheck 80mhz support:

http://www.arubanetworks.com/techdocs/ArubaOS_6.4.4.x_WebHelp/Web_Help_Index.htm#ArubaFrameStyles/ARM/ARM_Profiles.htm?

If you do show ap active right now, your channels will have an E, meaning 80 mhz.  There are only two channels in the 80mhz spectrum if you are not doing DFS and 4 channels if you allow DFS, but that is still not enough.  If you change "allowed" to "none" and uncheck 80mhz channels, that would give you 9 non-overlapping channels to play with, and improve your performance.

Thanks for the feedback.  After reading the articles and the post.  I better understand the out put of the CLI command.  The output makes more sense to me now.  I am a K12 with very dense AP installed.  There is an AP in the hallway 1 per 2 rooms and now an AP in every classroom.  I am in the process of adding Air Monitors and Spectrum monitors in all 150 schools.  I am not sure if this should be per site or allow the controllers to set the Air Monitors.

Quick question, why are you looking to place Air monitors?
