Scenario:
You are configuring a Standalone Aruba Mobility Controller, using ArubaOS 8.x.
All items have been addressed; you are online, APs are configured, on the air and accepting clients.
Because it is a standalone, you know it does not support Air Match so you are creating and tweaking the default radio, ARM, and HT profiles.
But it does not work.
No matter where you look in the WebGUI, you can’t find the linkages to apply these profiles that you have created.
This article is about how to enable “Show Advanced Profiles”. You must do this before you can apply the changes.
Read the section, in particular that starts “If you're looking to change profiles per AP-group, “.
NOW you are able to change and apply the new default radio, ARM, HT profiles.
