The following example describes the user Alice is the member of Mathematics group and hence cannot
discover the 00:1e:65:2d:ae:44 appleTv (specified in the example above) as it is not shared with the
Mathematics group. Similarly, the user Bob can view the appleTv as it is shared with the Physics group.

Bluetooth-Based Discovery and AirGroup
Apple devices support Bluetooth-based device discovery mechanism, which allows an Apple device to discover
an Apple TV that is within the Bluetooth range.
AirGroup supports only mDNS-based device discovery and does not support Bluetooth-based device discovery
mechanism.
AirGroup mDNS Static Records
AirGroup processes mDNS packets advertised by servers and creates the relevant cache entries. When a query
comes from a user, AirGroup responds with the appropriate cache entries with the relevant policies applied.
Starting with ArubaOS 6.4, AirGroup provides the ability for an administrator to add the mDNS static records
to cache, when a server is:
l not mDNS compliant.
l connected to a VLAN that is not trunked to the AirGroup supported controller.
The administrator can add these records manually to the cache using CLI commands for the servers that
adhere to the above conditions.
Important Points to Remember
Remember the following points when you create mDNS static records and add them to the cache:
l The mDNS static records do not expire as there is no cache refresh for static records. These static records
can be deleted by an administrator.
l The Administrator needs to ensure that the relevant records are updated manually, when the IP address of
a server is changed.
l The Disallow role policy configured on the CLI is accepted for static records. The Disable service policy is
accepted while responding to a query. Administrator has the privilege to configure static records of a
disabled service. Disallow vlan is not applicable for static records.
l ClearPass Policy Manager policies work with static servers.
Creating mDNS Static Records on a Controller
The Administrator can create the static records using the following methods:
l Group mDNS static records
