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 ClearPass Policy Manager support is enabled. For
example, depending on the 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.
