Introduction
The Aruba 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 AP 60/61 provides tr ansparent,
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 AP
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.
OTE: Installing the Aruba AP 60/61 requires setting the antenna power, which
N
requires professional training. The Aruba AP 60/61 installer must be
trained to perform this configuration.

The Aruba AP Setup Process
Setting up an Aruba AP typically consists of four stages:
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 separate ly ).
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 Appendix 2, “Provisioning Access Points.”
AP Deployment—Once provisioned, the AP can be physically installed at its
intended place of operation.
AP deployment is covered in Chapter 3, “AP Deployment”.
AP Configuration—The administrator defines the operational behavior for each
Aruba AP, such as RF characteristics and security fea tures.
For AP configuration information, refer to the ArubaOS User Guide.
6 Aruba AP 60/61 0500160
Installation Guide December 2005
Provisioning Access Points
Access Points are ra dio 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 th e 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:
z Plug and Play—Also known as the Aruba Discovery Protocol. This is the easi-
est 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.
z AP Provisioning—Using this AP programming mode, AP configuration parame-
ters are defined on the Mobility Controller (using the CLI or Web interface) and
then uploaded to the APs.
2
This method can be used for adding Aruba APs to a highly customized
network, or greatly simplified for the most common provisioning.
z Manual Provisioning—APs can be individually provisioned using a serial con-
sole 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 Mobility Controller.
OTE: Manual provisioning is intended for use when no Aruba Mobility
N
Controller is available, and is not gener ally recommended as the
primary method of AP provisioning. Plug and play or AP
programming mode are the preferred provisioning methods.
Aruba AP 60/61 7
Installation Guide
Provisioning Access Points
Chapter 2
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.
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.
Maintenance > Program AP > Re-Provision.
Aruba Discovery Protocol
Aruba Discovery Protocol (ADP) is a plug and play provisioning tool for Arub a 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 equiv alent 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 V endor Specific Options in DHCP. T o fac ilitate
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 whe n the DHCP re sponse
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
8 Aruba AP 60/61 0500160
Installation Guide December 2005
Provisioning Access Points
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 Con troller 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
OTE: If you have location-specific configurations for your Access Points, you
N
will need to apply this configuration information using AP Reprovisionin g.
Refer to the ArubaOS User Guide for details on AP Reprovisioning and
see the feature description below.
Chapter 2
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.

5. Specify the Aruba AP 60/61-specific parameters.
Configure the gain value appropriate for the location in which this AP will be
deployed. (See Table 3-1 for appropriate antenna gain values.)
OTE: If the AP being provisioned is a model with detachable antenna ca pability
N
(such as an Aruba AP-60), enter the antenna gain in dBi(e.g ., 4.0). This is
mandatory for all detachable antenna models as the AP will not 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 selec ted
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 f ollowing 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 Pr ogress. to P
(Provisioned).
OTE: Check that the configured parameters are reflected in the AP list entry.
N
OTE: Aruba Networks recommends that you provision each AP for a unique
N
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 reduc e 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.
OTE: Disable AP Provisioning after all the required APs are provisioned. Ports
N
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
12. Reboot the AP so the AP will come up with the new configured parameters.
Use the Reprovisioning tab for APs which are already deployed but need to be
reconfigured. See the ArubaOS User Guide for information on reprovisioning.

The LAN connection is optional unless POE is being used to power the AP.
For convenience, the adapter kit includes an FE coupler to connect RJ-45
cable ends together.
4. Connect power to the Aruba AP 60/61.
CAUTION: Be sure to comply with electrical grounding standards
during all phases of installation and operation of the AP.
Do not allow the Aruba AP 60/61 or optional power
adapter (if used) to be connected to or make contact with
metal or power outlets on a different electrical ground
than the device to which it is connected. Also, never
connect the AP to external storm grounding sources.
The Aruba AP 60/61 can receive electrical power using the following options:
z POE–If connecting the Aruba AP 60/61 to a device that supplies IEEE 802.3af
compliant POE, no additional power connection is necessary.
z Power Outlet
OTE: When the Aruba AP 60/61 is installed in an air-handling space, as
N
described in NEC (2002) Article 300.22(C), POE must be used instead
of a power outlet.
If local regulations and practices permit, connect the optional AC power
adapter (not included) to the DC power socket on the rear panel of the Aruba
AP 60/61 and plug it into an appropriate power outlet.
CAUTION: To prevent personal injury or damage to equipment,
use only the AC power adapter certified for this device
in the country where it is used.
OTE: The indicator LEDs on the Aruba AP 60/61 will remain dark during this
N
procedure.

Setting Aruba AP 60/61 Parameters
1. From the apboot prompt, config ure the host information, if necessary.
In order to provide centralized management of the APs, each Aruba AP
downloads its software image and configuration files from a master Mobility
Controller.
Setting the correct host information depends on the following:
z Does your network use direct IP addresses or DNS with host names?
z If using host names, is aruba-master acceptable for the master Mobility Con-
troller, or do you need to define a different name?
Depending on your answers, select one of the following steps:
z My network uses DNS and the aruba-master host name is acceptable.
This is the default. It requires your DNS to be configured to resolve
“aruba-master” to the IP address of the master Mobility Controller. Unles s
your system has been previously configured for different settings, you
can skip to Step 2.
Otherwise, if your system was previously configured for a different
setup, manually set the servername environment variable to the default
host name:
Chapter 2
apboot> setenv servername aruba-master
OTE: The master and serverip environment variables also affect how AP
N
source files are selected and should be cleared when using this
approach. To clear a variable, enter the setenv variable command with
no host name or address value:
apboot> setenv master
apboot> setenv serverip
When finished, proceed to Step 2.
z My network uses DNS, but I will use a different host name for the
Mobility Controller.
This requires that the servername variable be c onfigured with y our chosen
host name for the master Mobility Controller. It also requires that your
DNS be configured to resolve the specified host name to the IP address
of the master Mobility Controller.
To manually set the host name, use the following command:
apboot> setenv servername
<Mobility Controller host name>
