Multi-Switch AirGroup Cluster
AOS-W supports multiple switches running AirGroup to form a cluster. This feature enables iPad users on one
switch to discover Apple TV available on another switch, if both switches are part of the same cluster.
Multi-Switch AirGroup Cluster—Terminologies
AirGroup Domain
An AirGroup domain is a set of switches that are part of an AirGroup cluster. An administrator can configure
multiple AirGroup domains for a site-wide deployment. Individual local switches can independently select
relevant multiple AirGroup domains to form a multi-switch AirGroup cluster.
AirGroup Cluster
One or several AirGroup domains can form an AirGroup cluster. AirGroup cluster can have 100 AirGroup
domains. An AirGroup domain can include a list of likely switches which may participate in the multi-switch
AirGroup cluster. Figure 223 shows the AirGroup cluster and domain relationship:

Active-Domain
AirGroup allows one or more AirGroup domains to be a part of the AirGroup active-domain list on a switch. A
master or local switch may participate in one or more AirGroup clusters based on its active-domain list. The
switch must set the corresponding domain as active for the switch to be part of the AirGroup cluster.
In Figure 223, Switch 1, 2, and 3 belong to AirGroup Domain 1.
Sample AirGroup Cluster Topology
Figure 224 shows a typical master-local multi-switch deployment. In this topology, four local switches
terminate on a single master switch.
