Discovery of the serverip and master variables is necessary when the DHCP response does not
include the Vendor Specific option. The AP attempts to discover an Aruba Master switch by
sending multicast packets and broadcast packets on its subnet. To use the ADP discovery
method, the ADP discovery mechanism needs to be enabled on the Aruba Master Switch

If multicast routing is enabled in the IP network between the AP and the Master switch

Once these discovery prerequisites are met, the switch will respond to APs with the IP address

To enable ADP on an Aruba WLAN switch, enter:
(A5000) (config) #adp discovery enable
To enable IGMP-Join on an ADP multicast group on an Aruba WLAN switch, enter:
(A5000) (config) #adp igmp-join enable
Note If you have location-specific configurations for your Access Points, you will
need to apply this configuration information using AP Reprovisioning.

AP Reprovisioning
AP Reprovisioning is the process by which APs are assigned, for example, location codes.
Location codes are important for recalibration and triangulation. For details on AP
Reprovisioning, see the User Guide.
