1 About this Guide

This Guide provides instructions on how to install and configure your Cisco Aironet 1430 Series Wireless Bridge (hereafter called the bridge). This guide also provides bridge alignment instructions and limited troubleshooting procedures.

The Cisco Aironet 1430 Series Wireless bridge is Series Wireless Bridge. The 1430 series is a 802.11a wireless bridge supporting point-to-point and point-to-multipoint applications operating in the 4.9-, 5.6-, and 5.8-GHz spectrum. The bridge delivers long-range, high capacity, and is easy to deploy. The bridge supports 40 MHz channelization in the 5.6- and 5.8-GHz bands to deliver data rates at or above 130 Mbps. The bridge also supports external and integrated antenna configurations for various deployment scenarios for enterprise and commercial customer applications.

The bridge is deployed as an autonomous point-to-point bri in a simple autonomous environment. Cisco’s wireless controller software (WCS) management provides centralized management and monitoring services for the bridge.

5 Configuring the Bridge for the First Time

This chapter describes how to configure basic settings on your bridge for the first time. The contents of this chapter are similar to the instructions in the quick start guide that shipped with your bridge. You can configure all the settings described in this chapter using the command-line interface (CLI), but it might be simplest to browse to the bridge’s web-browser interface to complete the initial configuration and then use the CLI to enter additional settings for a more detailed configuration.

This chapter contains these sections:

• Before You Start, page 7

• Obtaining and Assigning an IP Address, page 8

• Connecting to the Bridge Locally, page 9

• Assigning Basic Settings, page 10

• What To Do Next, page 14

• Assigning an IP Address Using the CLI, page 15

• Using a Telnet Session to Access the CLI, page 15

Before You Start

Before you install the bridge, make sure you are using a computer connected to the same network as the bridge, and obtain the following information:

• From your network system

–

A system name

–

The case-sensitive wireless service set identifier (SSID) for your radio network

–

If not connected to a DHCP server, a unique IP address for your bridge (such as

172.17.255.115)

–

If the bridge is not on the same subnet as your PC, a default gateway address and subnet mask

–

A Simple Network Management Protocol (SNMP) community name and the SNMP file attribute (if SNMP is in use)

Resetting the Bridge to Default Settings

If you need to start over during the initial setup process, follow these steps to reset the bridge to factory default settings using the power injector’s Mode button:

Step 1 Disconnect the power jack from the power injector.

You can also use the web-browser interface to reset the bridge to defaults. Follow these steps to return to default settings using the web-browser interface:

Step 1 Open your Internet browser. You must use Microsoft Internet Explorer (version 5.x or later)

or Netscape Navigator (version 4.x).

Note If the bridge is configured with a static IP address, the IP address is not changed.

Obtaining and Assigning an IP Address

To browse to the bridge’s Express Setup page, you must either obtain or assign the bridge’s IP address using one of the following methods:

• Use defa the “Connecting to the Bridge Locally” section on page 9.

• Use a DHCP-assigned IP address using one of the following methods:

–

ult address 10.0.0.1 when you connect to the bridge locally. For detailed instructions, see

Provide your organization’s network administrator with your bridge’s Media Access Control (MAC) address. Your network administrator will query the DHCP server using the MAC address to identify the IP address. The bridge’s MAC address is on label attached to the bottom of the bridge.

THIRD FCC DRAFT (CISCO CONFIDENTIAL)

Connecting to the Bridge Locally

If you need to configure the bridge locally (without connecting the bridge’s power injector to a wired LAN), you can connect a PC to the power injector’s Ethernet port using a Category 5 Ethernet cable. You can use a local connection to the Ethernet port much as you would use a serial port connection.

Note You do not need a special crossover cable to connect your PC to the bridge’s power injector;

you can use either a straight-through cable or a crossover cable.

If the bridge is configured with defaul an IP address, it defaults to IP address 10.0.0.1 and becomes a mini-DHCP server. In that capacity, the bridge provides up to twenty IP addresses between 10.0.0.11 and 10.0.0.30 to an Ethernet-capable PC connected to the power injector’s Ethernet port.

The mini-DHCP server feature is disabled automatically bridge.

Caution When a bridge with default settings is connected on a wired LAN and does not receive an

IP address from a DHCP server, the bridge provides an IP address to any DHCP requests it receives.

Follow these steps to connect to the bridge locally:

Step 1 Make sure that the PC you intend to use is configured to obtain an IP address automatically,

or manually assign it an IP address from 10.0.0.31 to 10.0.0.40. Connect your PC to the power injector using a Category 5 Ethernet cable. You can use either a crossover cable or a straight-through cable.

Note When you connect your PC to the bridge’s power injector or reconnect your PC to the wired

LAN, you might need to release and renew the IP address on the PC. On most PCs, you can perform a release and renew by rebooting your PC or by entering ipconfig /release and ipconfig /renew commands in a command prompt window. Consult your PC operating instructions for detailed instructions.

Assigning Basic Settings

After you determine or assign the bridge’s IP address, you can browse to the bridge’s Express Setup page and perform an initial configuration. Follow these steps:

Step 1 Open your Internet browser. You must use Microsoft Internet Explorer (version 5.x or later)

or Netscape Navigator (version 4.x).

• IP Address—Use this setting to assign or change the bridge’s IP address. If DHCP is enabled for your network, leave this field blank.

Note If the bridge’s IP address changes while you are configuring the bridge using the web-browser

interface or a Telnet session over the wired LAN, you lose your connection to the bridge. If you lose your connection, reconnect to the bridge using its new IP address. Follow the steps in the “Resetting the Bridge to Default Settings” section on page 7 if you need to start over.

• IP Subn

You can also pre-configure the bridge into root or non

Protecting Your Wireless LAN

To prevent unauthorized access to your network, you must configure security settings. Because the bridge is a radio device, the bridge communicates beyond the physical boundaries of your building.

Assigning an IP Address Using the CLI

When you connect the bridge to the wired LAN, the bridge links to the network using a bridge virtual interface (BVI) that it creates automatically. Instead of tracking separate IP addresses for the bridge’s Ethernet and radio ports, the network uses the BVI.

When you assign an IP address to the bridge using the CLI, you mus Beginning in privileged EXEC mode, follow these steps to assign an IP address to the bridge’s BVI:
