Question:  How do I stop ARM scanning to improve application performance other than voice traffic?

 

Product and Software: This article applies to all Aruba controllers with ArubaOS 3.1 and later.
Earlier releases of ArubaOS have a functionality called voice aware ARM. This functionality stops ARM scanning while a voice call is in progress. If the AP continues to scan during a voice call, excessive jitter and packet loss causes poor voice quality.
The same reasoning can be applied to any mission-critical protocol, such as hand-held scanning and video traffic. So, beginning with ArubaOS 3.1, you can configure the type of traffic that will stop the APs from scanning. This functionality is part of the PEF license.
(config) #ip access-list session arm
(config-sess-arm)#any any svc-important permit disable-scanning

The AP where a client is connected will stop scanning for as long as this important type of traffic is present.
