Introduction 1
CHAPTER 1
Introduction
The Aruba AP60/61 (also known as the AP 60/61) is part of a
comprehensive wireless network solution. The device works in
conjunction with the Aruba Mobility Controller and can act as a
wireless access point or air monitor.
As a wireless Access Point (AP), the Aruba AP60/61 provides
transparent, secure, high-speed data communications between
wireless network devices (fixed, portable, or mobile computers
with IEEE 802.11a or IEEE 802.11b/g wireless adapters) and the
wired LAN.
As a wireless Air Monitor (AM), a feature unique to Aruba
products, the Aruba AP60/61 enhances wireless networks by
collecting statistics, monitoring traffic, detecting intrusions,
enforcing security policies, balancing wireless traffic load,
self-healing coverage gaps, and more.
NOTE—Installing the Aruba 60/61 requires setting the antenna
power, which requires professional training. The Aruba
60/61 installer must be trained to perform this configura-
tion.

This slot is compatible with a Kensington MicroSaver Security Cable (not
included) which can be used to prevent the unauthorized removal of the Aruba
AP60/61 from its installed location. To secure the Aruba AP60/61, wrap a
security cable around an immovable object, insert the cable’s lock into the
Kensington Security Slot, and turn the key.
NOTE—The serial number and model number are on the bottom of the unit.
The Aruba AP Setup Process
Setting up an Aruba AP typically consists of four stages:
1 WLAN Planning—The administrator determines how many Aruba APs will
be needed for their wireless network strategy and where they will be
deployed. This can be easily accomplished using Aruba’s automated RF
Plan site-survey software (available separately).
2 AP Provisioning—Provisioning provides each Aruba AP with initial settings
that allow it to locate the host Aruba Mobility Controller. Depending on the
network topology and services, AP provisioning can be performed manually
for each AP or plug-and-play for batches of APs.
AP provisioning is discussed in Chapter 2.
3 AP Deployment—Once provisioned, the AP can be physically installed at its
intended place of operation.
AP deployment is covered in Chapter 3.

Provisioning Access Points 9
CHAPTER 2
Provisioning Access Points
Access Points are radio broadcast devices and as such are
subject to governmental regulation. Network administrators
responsible for the configuration and operation of Access Points
must comply with local broadcast regulations. Specifically,
Access Points must use channel assignment and antenna gain
settings (for detachable antennas) appropriate to the location in
which the Access Point will be used. Aruba Networks, in
compliance with governmental requirements, has designed the
AP60 and AP61 such that only authorized network administrators
can change these settings. For more information on Access Point
configuration, refer to the ArubaOS User Guide.
Provisioning provides the AP with initial network settings that
allow it to locate the host Aruba Mobility Controller. The following
provisioning methods (listed in the order of preference
recommended by Aruba Networks) are available:
zPlug and Play—Also known as the Aruba Discovery Protocol.
This is the easiest method for AP provisioning. With plug and
play, Aruba APs can be connected to the network and brought
into operation automatically. Although plug and play requires
no manual intervention for the APs, this method does require
specific services to be configured on your network in advance.
zAP Provisioning—Using this AP programming mode, AP con-
figuration parameters are defined on the Mobility Controller
(using the CLI or Web interface) and then uploaded to the APs.
This method can be used for adding Aruba APs to a highly
customized network, or greatly simplified for the most common
provisioning.
zManual Provisioning—APs can be individually provisioned
using a serial console terminal connected to the AP. Although
this method is complex and requires considerable care, man-
ual provisioning can be used in almost any scenario, with or
without access to the Mobility Controller.

Aruba AP60/61: Installation Guide
10 Part 0500034-05 May 2005
NOTE—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:
zObtains the IP address of the TFTP server from which it downloads the AP
boot image
zIt 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
CAUTION—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.

Provisioning Access Points 11
Chapter 2
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 enabled on the network, the Aruba Mobility
Controllers need to be on the same broadcast domain as the AP or an “IP
Helper” must be configured to direct the broadcast ADP packets to the Aruba
Mobility Controller.
Once these discovery prerequisites are met, the Mobility Controller will
respond to APs with the IP address of the Master Aruba switch. The APs can
then obtain their image and configuration.
To enable ADP on an Aruba Mobility Controller, enter:
(A5000) (config) #adp discovery enable
To enable IGMP-Join on an ADP multicast group on an Aruba Mobility
Controller, 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. Refer to the ArubaOS User Guide for
details on AP Reprovisioning and see the feature description below.
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 ArubaOS User Guide.
AP Provisioning
AP Provisioning is useful for brand new APs with default configurations. To
perform AP Provisioning from the GUI:
1. Go to Maintenance > Program AP.
On this window, there are two tabs: Provisioning and Reprovisioning. The
Provisioning tab is selected by default.

2 Configure the APs Subnet and Netmask.
This is the subnet from which the AP gets an IP during provisioning. (This is not
the IP address the AP will use when deployed. The provisioning subnet should
be not be the same as an existing subnet on Mobility Controller.)
3 Select the Port or Port range for provisioning.
To set the Port Range, select the first and the last ports of your range. All the
ports in between are automatically selected. (Ports have to be sequentially
assigned.)

5 Specify the Aruba 60/61-specific parameters.
Configure the gain value appropriate for the location in which this AP will be
deployed. (See Tab l e 3- 1 for appropriate antenna gain values.)
NOTE—If the AP being provisioned is a model with detachable antenna capability (such as an Aruba
AP-60) enter the antenna gain in dBi, for example 4.0. This is mandatory for all detachable
antenna models as the AP will not will bring up its radio interface or function as an AP without
it.
Complete specifying Master Discovery and IP Settings and click Apply.

6 Plug the AP into one of the ports configured for provisioning.
If your AP is already plugged into the port, unplug it and plug it in again.
If AP is connected through POE, enter (in interface mode) no poe followed by
poe.
The AP will come up with an IP from the provisioning subnet
After the AP comes up it should be in the provisioning list. Provisioning list
shows the list of APs which are plugged into the provisioning ports.
7 The Clear Table button appears after an entry in the list appears.
To erase all the table entries, click Clear Table. (You cannot clear selected
entries.) If a number of APs are provisioned and you click Clear Table, only the
entries which come up afterwards can be provisioned.
If the entry does not show up in the AP list, check network connectivity. Go to
the AP console and verify if the AP has come up with the IP from the
provisioning subnet.
8 After the entry shows up on the page, configure the location, Host
IP/Name, Master IP address.
If AP is going to be assigned a static IP, click Use the following IP Address and
enter the IP address, Netmask, Gateway IP.
If the AP is going to obtain an IP address using DHCP, click Use IP Address
Using DHCP.
9 After configuring the required parameters, select the entry from the list (AP
to which the configuration has to be applied) and click Apply.
The State field changes from U(Unprovisioned) to In Progress. to P
(Provisioned).
NOTE—Check that the configured parameters are reflected in the AP list entry.
NOTE—Aruba Networks recommends that you provision each AP for a unique location as suggested
by site-survey planning. Label each AP with this location information and place the AP in its
proper location. Failure to place APs in the location for which they were provisioned will reduce
the effectiveness of such RF features as triangulation.
10 Click Back to return to the previous page
We can see that the Subnet is still configured and Port/s are selected.
11 When finished provisioning APs, click Disable to disable AP Provisioning.
NOTE—Disable AP Provisioning after all the required APs are provisioned. Ports that are enabled for
provisioning do not handle traffic. Therefore plugging an already provisioned AP into a port still
set to provisioning mode will prevent that AP from functioning.
Now the AP is configured with the Parameters given
