How to identify the UAC of a client?

What command within the CLI (or how to navigate to this within the GUI) can be run to identify the user anchor controller, and the standby, of a client, within the cluster?

When clicking on the number of clients on the MM in the GUI, click on "Customize Columns" to select the "Active Controller"  column and the "Standby Controller" column.

Re: How to identify the UAC of a client?

From the MM CLI you can do the following

 

(MM) [mynode] #show global-user-table list

 

which will display all users

 

or

 

(MM) [mynode] #show global-user-table list mac-addr xx:xx:xx:xx:xx:xx

 

which will display a specific user

 

The output of each will display a column "Current switch" which is the UAC

 

I hope this helps,

This post has some really good information/discussion on how UAC/S-UAC works from cjoseph, westcott, and jgoff - https://community.arubanetworks.com/t5/Wireless-Access/UAC-Assignment-After-Client-Leaves-User-Table/m-p/537082#M91626

From that same post from jgoff you can run two commands to show "active UAC/S-UAC assignments" and even cooler a command to "predict/calculate" what a client's UAC/S-UAC will be based on the current cluster-bucket-map-calculations for a client not in the User-Table.
