Scanning for VoIP-Aware ARM
ARM scanning on an AP during a call affects the voice quality. You can pause the ARM scanning on the AP when
a call is active by turning on the VoIP-Aware ARM Scanning support to avoid voice quality issues.
You can use the WebUI or CLI to enable VoIP-aware ARM scanning in the ARM profile.
In the WebUI
1. Navigate to the Configuration > AP Configuration page. Select either the AP Group or AP Specific.
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.
2. In the Profiles list, Expand the RF Management section.
3. Select Adaptive Radio Management (ARM) Profile.
4. Select a profile instance from the drop-down menu to edit that profile.
5. Select the VoIP Aware Scan option.
6. Click Apply.
For additional information on configuring an Adaptive Radio Management profile, see Configuring ARM Profiles

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.
2. Under Profiles, select Wireless LAN, then select Virtual AP. In the Virtual AP list, select the appropriate
virtual AP instance.
3. Select AAA profile. Select the 802.1x Authentication Profile to display in the Profile Details section.
4. Scroll down and deselect the Disable rekey and reauthentication for clients on call check box.
