— Manual provisioning is intended for use when no Aruba Mobility Controller is
available, and is not generally recommended as the primary method of AP pro-
visioning. Plug and play or AP programming mode are the preferred provision-
ing methods.
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
Maintenance > Program AP >
Re-Provision
. See the ArubaOS User Guide for more information on
reprovisioning existing APs.
Aruba Discovery Protocol
Aruba Discovery Protocol (ADP) is a plug and play provisioning tool for
AP60/61 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
network 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
C
AUTION
—
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.
