Enabling Mobile IP Home Agent Assignment
When you enable IP mobility in a mobility domain, the proxy mobile IP module determines the home agent for
a roaming client. An option related to voice clients that you can enable allows on-hook phones to be assigned a
new home agent to load balance voice client home agents across controllers in the mobility domain. See IP
Mobility on page 647 for more information about mobility.
Scanning for VoIP-Aware ARM

l If you selected the AP Group tab, click Edit by the name of the AP group with the ARM profile you want
to configure.
l If you selected the AP Specific tab, click Edit by the name of the AP with the ARM profile you want to
configure.

Disabling Voice-Aware 802.1X
The Voice-Aware 802.1X support is deprecated for ArubaOS 5.0 and later releases.
Although reauthentication and rekey timers are configurable on a per-SSID basis, an 802.1X transaction during
a call can affect voice quality. If a client is on a call, 802.1X reauthentication and rekey are disabled by default
until the call is completed. You disable or re-enable the “voice aware” feature in the 802.1X authentication
profile.
In the WebUI
1. Navigate to the Configuration > AP Configuration page. Select either AP Group or AP Specific.
l If you select AP Group, click Edit for the AP group name for which you want to disable voice awareness
for 802.1X.
l If you select AP Specific, select the name of the AP for which you want to disable voice awareness for
802.1X.
