CHAPTER 1
Introduction
The Aruba 60/61 (also known as the AP 60/61) is part of a comprehensive wireless network
solution. The device works in conjunction with the Aruba WLAN Switch and can act as a
wireless access point or air monitor.
As a wireless Access Point (AP), the Aruba 60/61 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 60/61
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 AP 60/61 requires setting the antenna power, which requires profes-
sional training. The AP60/61 installer must be trained to perform this configura-
tion.

location. To secure the Aruba 60/61, 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 WLAN Switch. 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.

4 AP Configuration—The administrator defines the operational behavior for each Aruba
AP, such as RF characteristics and security features.
For AP configuration information, refer to the Aruba AirOS User Guide.

Provisioning Access Points 7
Chapter 2
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 AirOS User Guide.
Provisioning provides the AP with initial network settings that allow it to locate the host Aruba
WLAN Switch. 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 configuration parameters are
defined on the WLAN switch (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.

8Aruba60/61 Part 0500034-05
Installation Guide October 2004
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,
manual provisioning can be used in almost any scenario, with or without access to the
WLAN switch.
Note Manual provisioning is intended for use when no Aruba WLAN Switch
is available, and is not generally recommended as the primary
method of AP provisioning. Plug and play or AP programming mode
are the preferred provisioning 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 AirOS 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 WLAN switch 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 switch 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 switch using the
Vendor Specific Options in DHCP. To facilitate ADP, Aruba APs include this Vendor Specific
CAUTION—When an AP60 powers up for the first time, the WLAN switch
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 AirOS User Guide for
instructions on manually setting antenna gain.

Provisioning Access Points 9
Chapter 2
Option in the requested Option list, and if the DHCP server is configured to return the IP
address of the Master switch, 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 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
(using the adp discovery enable command).
If multicast routing is enabled in the IP network between the AP and the Master switch
(which can be any one or more Aruba WLAN switches in the network), the IGMP-Join option
should be enabled on the Aruba WLAN switch (using the adp igmp-join enable
command). If multicast routing is not enabled on the network, the Aruba WLAN switches
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 WLAN switch.
Once these discovery prerequisites are met, the switch 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 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.
Refer to the AirOS 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 AirOS User Guide.
