AirGroup Features
AirGroup supports the following features:
l Sends unicast responses to mDNS or DLNAqueries and reduces the traffic footprint.
l Ensures cross-VLAN visibility and availability of AirGroup devices and services.
l Allows or blocks AirGroupservices for all users.
l Allows or blocks AirGroup services based on user roles.
l Allows or blocks AirGroup services based on VLANs.
l Matches devices to their closest services such as printers
AirGroup also enables context awareness for services across the network:
l AirGroup is aware of personal and shared devices. For example, an Apple TV in a dorm room can be
associated with the student who owns it or an Apple TV in a meeting room or a printer in a supply room that
is available to certain users, such as the marketing department.
l AirGroup is aware of the location of services when CPPM support is enabled. For example, depending on
proximity, a user would be presented with the closest printer instead of all the printers in the building.
l When configured, AirGroup enables a client to perform a location-based discovery. For example, when a
client roams from one Instant cluster to another, it can discover devices available in the new cluster to which
the client is currently connected.
The following figure shows an example of a higher-education environment with shared, local, and personal
services available to mobile devices.
