Lee,

Liberty University also uses Airwave in "monitor-only" mode for our Aruba 
controllers.

In the Aruba controller architecture, there is typically one "master" 
controller & several "local" controllers.

The master (This can be an HA pair) allows you to control most of the 
configuration from a central location. This controller also collects the RF 
information from the local controllers & performs the AP radio management 
decisions.  Some of this database can be offloaded to Airwave.

Vlan interface ip addresses, etc. need to be setup on each local controller.

If you have too many controllers for one master,( I don't remember the number, 
but I can check if you wish) I believe Aruba has an appliance that can 
centralize the configuration for multiple masters.

In our environment, the vast majority of toe configuration & AP provisioning is 
performed on the master controller. When you save the configuration, it is 
pushed out to the local controllers.

Subject: Big Aruba Environments- Management of multiple controllers

Wondering how bigger Aruba shops are centrally managing multiple controllers? 
From what I can tell right now, AirWave is pretty much an effective graphical 
monitoring tool, but is pretty anemic at configuration of Aruba. Am I missing 
something?
