With Airgroup 1.0 version, part of earlier InstantOS release, when a client roams from Cluster-1 to Cluster-2 it cannot discover the devices present in the Cluster-2, because the client was anchored to the home cluster. It would not discover the devices present in the foreign cluster.
With Airgroup 1.1 version, part of InstantOS 126.96.36.199-188.8.131.52, we have introduced location priority, where the roamed clients could discover the devices present in the connected cluster.
We need to disable "Airgroup across mobility domains" knob inorder to make use of Airgroup services in the foreign clusters when the client roams.
Moving across Instant Clusters i.e from Home Cluster to Foreign CLuster is L3 roaming.
Environment : This article applies to Aruba Instant Access Point running Aruba InstantOS 184.108.40.206-220.127.116.11 or later.

When a client roams from Cluster-1 to Cluster-2 and if it cannot discover the devices present in the Cluster-2, then below commands would help to understand the status of the Airgroup and troubleshoot accordingly.
# Show airgroup cache <Client Mac-address>
This command displays airgroup cache details for the IAP client.
#Show airgroup servers
List of Airgroup server details would be listed out with the above command.
#Show airgroup users
Shows the list of airgroup users
#Show airgroup vlan | include <vlan-id>
This command shows if the particular vlan is allowed for airgroup.
|(NOTE: Do not execute "show airgroup vlan" command, as it continues to shows the status for all the 4094 Vlans and it would therefore take much time)|
# show airgroup debug statistics
