CHAPTER 1

Introduction

The OmniAccess OAW-AP70 is part of a comprehensive wireless network solution. The device works in conjunction with the Alcatel Wireless LAN Switch and can act as a wireless access point or air monitor.

As a wireless Access Point (AP), the OmniAccess OAW-AP70 (also referred to as the AP AP70) 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 Alcatel products, the OmniAccess OAW-AP70 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 Alcatel AP70 requires setting the antenna

power, which requires professional training. The Alcatel AP70 installer must be trained to perform this configuration.

These vents promote proper air circulation for cooling the device. Do not allow these vents to be obstructed by mounting equipment, network cables, or any other material.

Fold-Out Internal Antenna

This fold-out antenna allows the OmniAccess OAW-AP70 to be used upright on a table, shelf, ceiling, or wall. If you are configuring external antennas, the internal antenna can be left closed.

NOTE—The serial number and the model number are on the bottom of the fold

out antenna panel.

The Alcatel AP Setup Process

Setting up an Alcatel AP typically consists of four stages:

1 Wireless LAN Planning—The administrator determines how many Alcatel

APs will be needed for their wireless network strategy and where they will be deployed. This can be easily accomplished using Alcatel’s automated RF Plan site-survey software (available separately).

2 AP Provisioning—Provisioning provides each Alcatel AP with initial settings

that allow it to locate the host Alcatel Wireless LAN 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, each 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 Alcatel AP, such as RF characteristics and security features.

For AP configuration information, refer to the Alcatel AOS-W User Guide.

6 Part 031644-00 May 2005

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. Alcatel Networks, in compliance with governmental requirements, has designed the Alcatel AP70 such that only authorized network administrators can change these settings. Once an administrator changes the antenna gain configuration, the Alcatel software automatically adjusts the power level to the appropriate setting. For more information on Access Point configuration, refer to the AOS-W 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 Alcatel Wireless LAN Switch. The following provisioning methods (listed in the order of preference recommended by Alcatel Networks) are available:

z Plug and Play—Also known as the Alcatel Discovery Protocol.

This is the easiest method for AP provisioning. With plug and play, Alcatel 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 con-

figuration parameters are defined on the Wireless LAN switch (using the CLI or Web interface) and then uploaded to the APs.

This method can be used for adding Alcatel APs to a highly customized network, or greatly simplified for the most common provisioning.

Provisioning Access Points 7

OmniAccess OAW-AP70: Installation Guide

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 Wireless LAN switch.

NOTE—Manual provisioning is intended for use when no Alcatel Wireless LAN 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

reprovisioning existing APs.

. See the AOS-W User Guide for more information on

CAUTION—When an Alcatel AP70 powers up for the first time, it is provisioned as having an internal antenna. If the network administrator wants to configure the Alcatel AP70 with an external (detachable) antenna, The network administrator must select the External Antenna option and set the antenna gain manually (in Maintenance > Wireless LAN > Program AP > Provision) before the Alcatel AP70 can function as an Access Point. Until the antenna gain is set, the Alcatel AP70 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.

Alcatel Discovery Protocol

Alcatel Discovery Protocol (ADP) is a plug-and-play provisioning tool for Alcatel AP70 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 Alcatel Wireless LAN 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 Alcatel 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, Alcatel 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 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.

8 Part 031644-00 May 2005

Chapter 2

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 Alcatel 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 Alcatel 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 Alcatel Wireless LAN switches in the network), the IGMP-Join option should be enabled on the Alcatel Wireless LAN switch (using the adp igmp-join enable command). If multicast routing is not enabled on the network, the Alcatel Wireless LAN 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 Alcatel Wireless LAN switch.

Once these discovery prerequisites are met, the switch will respond to APs with the IP address of the Master Alcatel switch. The APs can then obtain their image and configuration.

To enable ADP on an Alcatel Wireless LAN switch, enter:

(A6000) (config) #adp discovery enable

To enable IGMP-Join on an ADP multicast group on an Alcatel Wireless LAN switch, enter:

(A6000) (config) #adp igmp-join enable

OTE—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.

Provisioning Access Points 9

OmniAccess OAW-AP70: Installation Guide

AP Provisioning

AP Provisioning is useful for brand new APs with default configurations. To perform AP Provisioning from the GUI:

1. Go to

On this window, there are two tabs: Provision and Reprovision. The Provisioning tab is selected by default.

Maintenance > Program AP.

FIGURE 2-1 Provisioning Tab

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.)

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.

10 Part 031644-00 May 2005

Chapter 2

FIGURE 2-2 Port Range Screen

5 Specify the Alcatel AP70-specific parameters.

Internal Antenna is the default. If you select External Antenna, configure the

gain value appropriate for the location in which this AP will be deployed. (See

Tab le 3- 1 for appropriate antenna gain values.) You can connect from one to

four external antennas on the Alcatel AP70. Connecting both .a or .b/g antenna jacks enables antenna diversity.

NOTE—If you are provisioning detachable antennas, enter the antenna gain in dBi, for example 4.0.

This is mandatory for all detachable antennas as the AP will not will bring up its radio interface or function as an AP without it.

If you select External Antenna and do not configure the gain, the AP will function as an Air Monitor.

Complete the IPSec (optional), Master Discovery, and IP Settings and click

Apply.

Provisioning Access Points 11

OmniAccess OAW-AP70: Installation Guide

NOTE—The IPSec settings are designed to protect all traffic (control and data)

between a remote AP and a Wireless LAN switch. AP data is always encrypted, but without an IPSec tunnel, AP control traffic is sent in the clear. To set up an IPSec tunnel, configure the preshared key, user name (the AP PAP username that is configured on the switch), and the user name password. Also configure the VPN on the switch so that the switch end of the IPSec tunnel is also defined.

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 When the AP entry redisplays, 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.

10 When the AP is provisioned, the State will have changed to P

(Provisioned).

OTE—Check that the configured parameters are reflected in the AP list entry.

NOTE—Alcatel 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.

11 Click Back to go into the previous page

We can see that the Subnet is still configured and Port/s are selected.

12 Part 031644-00 May 2005

12 When finished provisioning APs, click Disable to disable AP Provisioning.

OTE—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

13 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 AOS-W User Guide for information on reprovisioning.

1.IEEE 802.3af-complaint devices like the Alcatel AP70 use the same wire pairs for data versus for power. Within the 802.3af standard, there are two sub-specifications on how wire pairs are assigned. Alcatel conforms to 802.3af, subparagraph a. If your POE installation uses all-Alcatel equipment, you are assured proper operation. However, if you use non-Alcatel POE equipment, make sure it conforms to the same standard that Alcatel uses. Using POE equipment using IEEE 802.3af subparagraph b wiring assignments, or POE equipment not conforming to the 803.2af standard may result in damaged equipment.
