General AirGroup Limitations
The AirGroup feature has the following limitations:
l AirGroup is supported only in tunnel and decrypt-tunnel forwarding modes.
l If you use CPPM to define AirGroup users, the shared user and role lists, and location attributes cannot
exceed 1000 characters.
l The RTSP protocol does not support AirPlay on an Apple TV receiver if you enable NAT on the user VLAN
interface.
l The location-based access feature only supports AP FQLNs (Fully Qualified Location Names) configured in
the format <ap name>.floor <number>.<building>.<campus>. The AP names cannot contain periods.
l AirGroup’s DLNA discovery works across VLANs, however, media streaming from Windows Media Server
does not work across VLANs. This limitation is because of Digital Rights Management (DRM) support in
Windows Media Server, which restricts media sharing across VLANs. Media streaming works only when both
client and server are connected to the same VLAN.
l Android devices cannot discover media server while using the native music and video player applications
and when they are connected across VLANs. For example, Samsung Tab 3 cannot discover the media server
on Samsung Galaxy S4 while using the native music and video player applications. Android devices can
discover media server when they are connected in the same VLAN. This restriction is forced by Samsung
devices.
l Xbox cannot be added as an extender to the Windows clients using the Windows Media Center application
with the AirGroup feature enabled. You need to disable the AirGroup feature to add Xbox as an extender.
l Wireless Clients such as iPad and iPhone running the Sonos Controller application cannot discover Sonos
music system with the AirGroup is enabled.
Integrated Deployment Model
In the integrated deployment model, AirGroup features are integrated with the WLAN controller that
terminates all APs and provides WLAN services. This deployment model also supports optional integration with
CPPM. When you implement AirGroup in an integrated deployment, upgrade the controller to ArubaOS 6.4 or
later, and trunk all VLANs with wired devices (such as printers) to the AirGroup controller.
If your deployment requires ClearPass Policy Manager integration, complete the procedures described in ClearPass
Policy Manager User Guide and ClearPass Guest Deployment Guide before performing the steps described in this
section.
Master-Local Controller Synchronization
You can configure AirGroup from the master controller to ease the deployment. The master controller then
synchronizes the AirGroup configuration elements on all associated local controllers it manages. AirGroup
configurations can belong to any of the following categories:
Master — These commands must be configured from a master controller. The master controller pushes the
AirGroup configurations to all the applicable local controllers.
l AirGroup custom service definition. For more information, see Integrated Deployment Model on page
1045.
l AirGroup disallow user-role (service filtering) definition. For more information, see Configuring the disallow-
role for an AirGroup Service on page 1050.
l AirGroup disallow VLAN (service filtering) definition. For more information, see Restricting AirGroup Servers
on a VLAN based on an AirGroup Service on page 1050.
