Each of these three methods is explained in the following sections. Use these 
procedures for initial provisioning of APs. To change the configuration for APs 
that have already been provisioned, go to

See the ArubaOS User Guide for more information on reprovisioning existing APs.

Aruba Discovery Protocol (ADP) is a plug and play provisioning tool for Aruba AP 
60/61 Access Points. ADP performs two tasks:

z

Obtains the IP address of the TFTP server from which it downloads the AP 
boot image 

z

It discovers the IP address of the master Aruba Mobility Controller in the net-
work from which the AP can download its configuration.

The address of the TFTP server that ADP discovers is the equivalent of the 
BOOTROM environment variable 

serverip. The IP address of the Aruba master 

Mobility Controller is the equivalent of the environment variable 

master.

ADP can discover these values using DHCP or by discovery. In the case of DHCP, 
ADP relies on a DHCP server which is configured to return the IP address of the 
Master Mobility Controller using the Vendor Specific Options in DHCP. To facilitate 
ADP, Aruba APs include this Vendor Specific Option in the requested Option list, 
and if the DHCP server is configured to return the IP address of the Master 
Mobility Controller, the IP address will be a part of the DHCP response. This is 
used by the AP to get its image as well as its configuration.

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 Mobility Controller 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 Mobility Controller (using 
the 

adp discovery enable command).

If multicast routing is enabled in the IP network between the AP and the Master 
Mobility Controller (which can be any one or more Aruba Mobility Controllers in 
the network), the IGMP-Join option should be enabled on the Aruba Mobility 
Controller (using the 

adp igmp-join enable command). If multicast routing is not 

When an AP60 powers up for the first time, the Mobility 
Controller will recognize that it is detachable-antennas 
capable. The network administrator must set the antenna 
gain manually before the AP60 can function as an Access 
Point. Until the antenna gain is set, the AP60 with 
detachable antennas will function as an Air Monitor but 
will not process wireless packets as an Access Point. 
Refer to the ArubaOS User Guide for instructions on 
manually setting antenna gain.
