1030 | AirGroup Dell Networking W-Series ArubaOS 6.4.x| User Guide
l Provides and maintains seamless connectivity of clients and services across VLANs and SSIDs. It minimizes
the mDNS traffic across the wired and wireless network, thereby preserving wired network bandwidth and
WLAN airtime.
With AirGroup:
l An AirGroup operator—an end user such as a student can register personal devices. The devices registered
by the operator can then automatically be shared with each other.
l Each user can create a user group, such as friends and roommates with whom the user can share the
registered devices.
l AirGroup administrators can register and manage an organization’s shared devices such as printers or
conference room Apple TV. The administrator can grant global access to each device, or limit access based
on user name, role, or location.
This chapter provides configuration information for network administrators to enable AirGroup on a Dell
controller and CPPM and to register devices with ClearPass Guest.
AirGroup also enables context awareness for services across the network:
l AirGroup is aware of personal devices. An Apple TV in a dorm room, for example, can be associated with the
student who owns it.
l AirGroup is aware of shared resources, such as an Apple TV in a meeting room, a printer available to multiple
users, or AirPlay in a classroom where a laptop screen is projected on HDTV monitor.
l AirGroup is aware of the location of services—for example, an iPad is presented with the closest printer
location instead of all the printers in the building. If a user in a conference room wants to use an Apple TV
receiver to project a MacBook screen on an HDTV monitor, the location-aware controller shows the Apple
TV that is closest to that user.
AirGroup Services
The AirGroup supports zero configuration services. The services are pre configured and are available as part of
the factory default configuration. The administrator can also enable or disable individual services by using the
controller WebUI.
The following services are enabled by default on the controller:
l AirPlay — Apple AirPlay allows wireless streaming of music, video, and slide shows from your iOS device to
Apple TV and other devices that support the AirPlay feature.
l AirPrint — Apple AirPrint allows you to print from an iPad, iPhone, or iPod Touch directly to any AirPrint
compatible printers.
l DIAL — Wi-Fi-enabled streaming devices like Google Chromecast, Roku, Amazon FireTV, and more advertise
the Discovery and Launch (DIAL) protocol for clients to search for an available device on a wireless network.
Once a device is discovered, the protocol synchronizes information on how to connect to the device. The
streaming device connects to a television through an HDMI port to wirelessly stream video and music
content to the TV screen from smart phone (both Android and Apple iOS), tablet, laptop or desktop
computer devices.
The following services are disabled by default on the controller:
l iTunes — iTunes service is used by iTunes Wi-Fi sync and iTunes home-sharing applications across all Apple
devices. For best practices, see the Apple iTunes Wi-Fi Synchronization and File Sharing on page 1041.
l RemoteMgmt — Use this service for remote login, remote management, and FTP utilities on Apple devices.
l Sharing — Applications such as disk sharing and file sharing, use the service ID that are part of this service
on one or more Apple devices. For best practices, see the Apple iTunes Wi-Fi Synchronization and File
Sharing on page 1041.
l Chat — The iChat (Instant Messenger) application on Apple devices uses this service.
