CHAPTER 1

Introduction

The Aruba 70 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 70 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 70 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 70 requires setting the antenna power, which requires professional

training. The AP 70 installer must be trained to perform this configuration.

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.

Installation Guide October 2004

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.

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 AP 70 such that only authorized network administrators can change these settings. Once an administrator changes the antenna gain configuration, the Aruba software automatically adjusts the power level to the appropriate setting. For more information on Access Point configuration, refer to the User Guide. For information on setting the antenna gain, see Figure 2-2.

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:

z Plug 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.

z AP 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.

Provisioning Access Points 9

Chapter 2

z Manual 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 User Guide for more information on reprovisioning existing APs.

CAUTION—When an AP 70 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 (in Maintenance > WLAN > Program AP > Provision) before the AP 70 can function as an Access Point. Until the antenna gain is set, the AP 70 with detachable antennas will function as an Air Monitor but will not process wireless packets as an Access Point. Refer to the User Guide for instructions on manually setting antenna gain.

Aruba Discovery Protocol

Aruba Discovery Protocol (ADP) is a plug and play provisioning tool for AP 70 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 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

10 Aruba 70 Part 0500044

Installation Guide October 2004

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 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 User Guide.

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.)

4 Enter the required information and click Enable.The Port Range screen displays.

FIGURE 2-2 Port Range Screen

5 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.

6Click the Refresh link (not the browser Refresh option) to see if the AP entry has

displayed.(This might take a moment.)

If you cannot see the entry after 1-2 minutes, click Refresh again.

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.

7 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.

8 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.

9 After a few seconds, click the Refresh link again and the State will have changed 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 go into 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.

14 Aruba 70 Part 0500044

Installation Guide October 2004

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

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 AirOS User Guide for information on reprovisioning.
