Configuring the Access Point/Bridge for the
This chapter describes how to configure basic settings on your access point/bridge for the first time. You can configure all the settings described in this chapter using the CLI, but it might be simplest to browse to the access point/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
•Obtaining and Assigning an IP Address
•Assigning Basic Settings
•Configuring Basic Security Settings
•Using the IP Setup Utility
•Using a Telnet Session to Access the CLI
•Resetting the Access Point/Bridge to Default Settings
Before You Start
For security reasons, the access point/bridge ships with no configuration and its radio disabled. You must configure the access point/bridge, which includes assigning at least one Service Set Identifier (SSID), which enables the access point/bridge's radio.
Before you install the access point/bridge, make sure you are using a computer connected to the same network as the access point/bridge, and obtain the following information from your network administrator:
•A host name for the access point/bridge
•If not connected to a DHCP server, a unique IP address for your access point/bridge (such as 172.17.255.115)
•If the access point/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)
•If you use IPSU to find the access point/bridge IP address, the MAC address from the product label on the access point/bridge (such as 00164625854c)
Default IP Address and Role in Radio Network Behavior
When you connect a 1300 series access point/bridge with a default configuration to your LAN, the access point/bridge attempts to get an IP address from the DHCP server. If no DHCP server is found, the access point/bridge continues to request a DHCP address. To eliminate this condition, you must connect to the access point/bridge using its console port. See the "Using the Console Port to Access the CLI" section for further information.
The access point/bridge assumes a radio network role of a root access point. To configure it as a bridge, you must manually place it in Install Mode in order to align the antennas and establish a link. In the Install Mode, one access point/bridge must be configured as a root bridge and the other a non-root bridge. To facilitate the configuration, an automatic option is available when the access point/bridge is in the install mode. After the wireless link is established and the bridge antennas are aligned, you take both access point/bridges out of Install Mode and place them on your LAN as root and non-root bridges.
Obtaining and Assigning an IP Address
To browse to the access point/bridge's Express Setup page, you must either obtain or assign the access point/bridge's IP address using one of the following methods:
•Assign a static IP address using the access point/bridge console port. For more information, see the "Assigning an IP Address Using the CLI" section
•Use a DHCP server (if available) to automatically assign an IP address. You can find out the DHCP-assigned IP address using one of the following methods:
–Provide your organization's network administrator with your access point/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 access point/bridge's MAC address is on the label attached to the bottom of the access point/bridge.
–If a DHCP server is present, use the Cisco IP Setup Utility (IPSU) to identify an assigned IP address. You cannot assign an IP address using IPSU. IPSU runs on most Microsoft Windows operating systems: Windows 9x, 2000, Me, NT, and XP.
You can download IPSU from the Software Center on Cisco.com. Click this link to browse to the Software Center:
–If the unit is a non-root bridge, browse to the Associations page on the root bridge to which the non-root is associated. The non-root bridge's MAC address and IP address appear on the root bridge's Associations page.
Using the Console Port to Access the CLI
Follow these steps to access the CLI by connecting to the serial port:
Step 1 Connect a nine-pin, female DB-9 to RJ-45 serial cable to the RJ-45 serial port on the power injector and to the COM port on your PC. Figure 2-1 shows the power injector's serial port connector.
Figure 2-1 Serial Port Connector
Serial port connector (RJ-45 connector)
Note The Cisco part number for the DB-9 to RJ-45 serial cable is AIR-CONCAB1200. Browse to http://www.cisco.com/go/marketplace to order a serial cable.
Step 2 Set up a terminal emulator to communicate with the access point/bridge. Use the following settings for the terminal emulator connection: 9600 baud, 8 data bits, no parity, 1 stop bit, and no flow control.
Step 3 When the terminal emulator is activated, press Enter. An Enter Network Password window appears.
Step 4 Enter your username in the User Name field. The default username is Cisco.
Step 5 Enter the access point/bridge password in the Password field and press Enter. The default password is Cisco.
When the CLI activates, you can enter CLI commands to configure the access point/bridge.
Assigning an IP Address Using the CLI
When you connect the access point/bridge to the wired LAN, the access point/bridge links to the network using a bridge virtual interface (BVI) that it creates automatically. Instead of tracking separate IP addresses for the access point/bridge's Ethernet and radio ports, the network uses the BVI.
Note The access point/bridge supports only one BVI. Configuring more than one BVI might cause errors in the access point/bridge's ARP table.
When you assign an IP address to the access point/bridge using the CLI, you must assign the address to the BVI. Beginning in privileged EXEC mode, follow these steps to assign an IP address to the access point/bridge's BVI and assign an IP address and subnet mask (address mask):
Enter global configuration mode.
Enter interface configuration mode for the BVI.
ip address address
Assign an IP address and address mask to the BVI.
Note If you are connected to the access point/bridge using a Telnet session, you lose your connection to the access point/bridge when you assign a new IP address to the BVI. If you need to continue configuring the bridge using Telnet, use the new IP address to open another Telnet session to the access point/bridge.
Note If you do not assign an address mask, the address 255.255.255.224 is assigned automatically.
Returns to privileged EXEC mode.
Note You can also use Ctrl-Z to return to the privileged EXEC mode.
Verify your entry.
copy running-config startup-config
(Optional) Save your entry in the configuration file.
When you have configured the access point/bridge IP address, you can use your Internet browser to access the unit's graphical user interface (GUI).
Connecting to the Access Point/Bridge Locally
If you need to configure the access point/bridge locally (without connecting the access point/bridge to a wired LAN), you can connect a PC to the Ethernet port on the long-reach power injector using a Category 5 Ethernet cable. You can use a local connection to the power injector's 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 power injector; you can use either a straight-through cable or a crossover cable.
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 within the same subnet as the access point/bridge IP address. For example, if you assigned the access point/bridge an IP address of 10.0.0.1, assign the PC an IP address of 10.0.0.20.
Step 2 With the power cable disconnected from the power injector, 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 Communication takes place between the power injector and the access point/bridge using Ethernet Port 0. Do not attempt to change any of the Ethernet Port 0 settings.
Step 3 Connect the power injector to the access point/bridge using dual coaxial cables.
Step 4 Connect the power injector power cable and power up the access point/bridge.
Step 5 Follow the steps in the "Assigning Basic Settings" section. If you make a mistake and need to start over, follow the steps in the "Resetting the Access Point/Bridge to Default Settings" section.
Step 6 After configuring the access point/bridge, remove the Ethernet cable from your PC and connect the power injector to your wired LAN.
Note When you connect your PC to the access point/bridge 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 access point/bridge's IP address, you can browse to the access point/bridge's Express Setup page and perform an initial configuration:
Step 1 Open your Internet browser. The access point/bridge web-browser interface is fully compatible with these browsers: Microsoft Internet Explorer versions 5.0, 5.01, 5.5 and 6.0; and Netscape Navigator versions 4.79 and 7.0.
Step 2 Enter the access point/bridge's IP address in the browser address line and press Enter. An Enter Network Password screen appears.
Step 3 Enter the case-sensitive username Cisco and press Tab to advance to the Password field.
Step 4 Enter the case-sensitive password Cisco and press Enter. The Summary Status page appears. Figure 2-2 shows the Summary Status page.
Figure 2-2 Summary Status Page
Step 5 Click Express Setup. The Express Setup screen appears. Figure 2-3 shows the Express Setup page.
Figure 2-3 Express Setup Page
Step 6 Enter the configuration settings you obtained from your system administrator. The configurable settings include:
•Host Name— The host name, while not an essential setting, helps identify the access point/bridge on your network. The host name appears in the titles of the management system pages.
Note You can enter up to 32 characters for the host name. However, when the wireless device identifies itself to client devices, it uses only the first 15 characters in the host name. If it is important for client users to distinguish between wireless devices, make sure a unique portion of the host name appears in the first 15 characters.
Note When you change the host name, the wireless device resets the radios, causing associated client devices to disassociate and quickly reassociate.
•Configuration Server Protocol—Click on the button that matches the network's method of IP address assignment.
–DHCP—IP addresses are automatically assigned by your network's DHCP server.
–Static IP—The access point/bridge uses a static IP address that you enter in the IP address field.
•IP Address—Use this setting to assign or change the access point/bridge's IP address. If DHCP is enabled for your network, leave this field blank.
Note If the access point/bridge's IP address changes while you are configuring the access point/bridge using the web-browser interface or a Telnet session over the wired LAN, you lose your connection to the access point/bridge. If you lose your connection, reconnect to the access point/bridge using its new IP address. Follow the steps in the "Resetting the Access Point/Bridge to Default Settings" section if you need to start over.
•IP Subnet Mask—Enter the IP subnet mask provided by your network administrator so the IP address can be recognized on the LAN. If DHCP is enabled, leave this field blank.
•Default Gateway—Enter the default gateway IP address provided by your network administrator. If DHCP is enabled, leave this field blank.
•SNMP Community—If your network is using SNMP, enter the SNMP Community name provided by your network administrator and select the attributes of the SNMP data (also provided by your network administrator).
•Role in Radio Network—Click on the button that describes the role of the access point/bridge on your network.
–Access Point—A root device; accepts associations from clients and bridges wireless traffic from the clients to the wireless LAN. This setting can be applied to any access point.
–Repeater—A non-root device; accepts associations from clients and bridges wireless traffic from the clients to root access point connected to the wireless LAN. This setting can be applied to any access point.
–Root Bridge—Establishes a link with a non-root bridge. In this mode, the device also accepts associations from clients.
–Non-Root Bridge—In this mode, the device establishes a link with a root bridge.
–Install Mode—Places the access point/bridge into installation mode so you can align and adjust a bridge link for optimum efficiency.
–Workgroup Bridge—Emulates a Cisco Aironet 350 Series Workgroup Bridge. In the Workgroup bridge mode, the access point functions as a client device that associates with a Cisco Aironet access point or bridge.
–Scanner—Performs as a network monitoring device. In the Scanner mode, the access point does not accept associations from clients. It continuously scans and reports wireless traffic it detects from other wireless devices on the wireless LAN. All access points can be configured as a scanner.
Note The access point/bridge defaults to the Root AP mode. It must be manually set to the Install-Mode for use as a bridge. In bridge modes, one bridge in any pair or group of bridges must be set to root, and the bridge or bridges associated to the root bridge must be set to non-root.
•Optimize Radio Network for—Use this setting to select either preconfigured settings for the access point/bridge radio or customized settings for the access point/bridge radio. See the "Configuring the Radio Distance Setting" section on page 6-16 for more information on data rates and throughput.
–Throughput—Maximizes the data volume handled by the access point/bridge but might reduce its range. When you select Throughput, the access point/bridge sets all data rates to basic.
–Range—Maximizes the access point/bridge's range but might reduce throughput. When you select Range, the access point/bridge sets the 6-Mbps rate to basic and the other rates to enabled.
–Default—The access point/bridge retains default radio settings that are designed to provide good range and throughput for most access point/bridges.
–Custom—Takes you to the Network Interfaces: Radio-802.11G Settings page. The access point/bridge uses settings you enter on this page.
•Aironet Extensions—This setting is always enabled on 1300 series access point/bridges.
Step 7 Click Apply to save your settings. If you changed the IP address, you lose your connection to the access point/bridge. Browse to the new IP address to reconnect to the access point/bridge.
Your access point/bridge is now running but probably requires additional configuring to conform to your network's operational and security requirements.

Protecting Your Wireless LAN
After you assign basic settings to your access point/bridge, you must configure security settings to prevent unauthorized access to your network. Because it is a radio device, the access point/bridge can communicate beyond the physical boundaries of your building. You can use Express Security page in the Configuring Basic Security Settings section to set basic security settings for your access point/bridge. Advanced security features can be found in the following chapters:
•A unique SSID that are not broadcast in the access point/bridge beacon (see Chapter 7, "Configuring Multiple SSIDs"
•WEP and WEP features (see Chapter 9, "Configuring Cipher Suites and WEP")
•Dynamic WEP and access point/bridge authentication (see Chapter 10, "Configuring Authentication Types")
Configuring Basic Security Settings
After you assign basic settings to your access point, you must configure security settings to prevent unauthorized access to your network. Because it is a radio device, the access point can communicate beyond the physical boundaries of your worksite.
Just as you use the Express Setup page to assign basic settings, you can use the Express Security page to create unique SSIDs and assign one of four security types to them. Figure 2-4 shows the Express Security page.
Figure 2-4 Express Security Page
The Express Security page helps you configure basic security settings. You can use the web-browser interface's main Security pages to configure more advanced security settings.
Understanding Express Security Settings
The SSIDs that you create using the Express security page appear in the SSID table at the bottom of the page. You can create up to 16 SSIDs on the wireless device.
In Cisco IOS Release 12.3(7)JA, there is no default SSID. You must configure an SSID before client devices can associate to the access point/bridge.
If you use VLANs on your wireless LAN and assign SSIDs to VLANs, you can create multiple SSIDs using any of the four security settings on the Express Security page. However, if you do not use VLANs on your wireless LAN, the security options that you can assign to SSIDs are limited because, on the Express Security page, encryption settings and authentication types are linked. Without VLANs, encryption settings (WEP and ciphers) apply to an interface such as the 2.4-GHz radio, and you cannot use more than one encryption setting on an interface. For example, when you create an SSID with static WEP with VLANs disabled, you cannot create additional SSIDs with WPA authentication because they use different encryption settings. If you find that the security setting for an SSID conflicts with another SSID, you can delete one or more SSIDs to eliminate the conflict.
Express Security Types
Table 2-2 describes the four security types that you can assign to an SSID.
Table 2-2 Security Types on Express Security Setup Page
Security Features Enabled
This is the least secure option. You should use this option only for SSIDs used in a public space and assign it to a VLAN that restricts access to your network.
Static WEP Key
This option is more secure than no security. However, static WEP keys are vulnerable to attack. If you configure this setting, you should consider limiting association to the access point based on MAC address or, if your network does not have a RADIUS server, consider using an access point as a local authentication server.
Mandatory WEP encryption, no key management, and open authentication. In Root AP mode, client devices cannot associate using this SSID without a WEP key that matches the access point key.
This option enables 802.1x authentication (such as LEAP, PEAP, EAP-TLS, EAP-GTC, EAP-SIM, and others) and requires you to enter the IP address and shared secret for an authentication server on your network (server authentication port 1645). Because 802.1x authentication provides dynamic encryption keys, you do not need to enter a WEP key.
Mandatory 802.1x authentication, In Root AP mode, client devices that associate using this SSID must perform 802.1x authentication.
Wi-Fi Protected Access (WPA) permits wireless access to users authenticated against a database through the services of an authentication server, then encrypts their IP traffic with stronger algorithms than those used in WEP. As with EAP authentication, you must enter the IP address and shared secret for an authentication server on your network (server authentication port 1645).
Mandatory WPA authentication. In Root AP mode, client devices that associate using this SSID must be WPA-capable.
Express Security Limitations
Because the Express Security page is designed for simple configuration of basic security, the options available are a subset of the access point/bridge's security capabilities. Keep these limitations in mind when using the Express Security page:
•If the No VLAN option is selected, the static WEP key can be configured once. If you select Enable VLAN, the static WEP key should be disabled.
•You cannot edit SSIDs. However, you can delete SSIDs and re-create them.
•You cannot assign SSIDs to specific radio interfaces. The SSIDs that you create are enabled on all radio interfaces. To assign SSIDs to specific radio interfaces, use the Security SSID Manager page.
•You cannot configure multiple authentication servers. To configure multiple authentication servers, use the Security Server Manager page.
•You cannot configure multiple WEP keys. To configure multiple WEP keys, use the Security Encryption Manager page.
•You cannot assign an SSID to a VLAN that is already configured on the access point/bridge. To assign an SSID to an existing VLAN, use the Security SSID Manager page.
•You cannot configure combinations of authentication types on the same SSID (for example, MAC address authentication and EAP authentication). To configure combinations of authentication types, use the Security SSID Manager page.
Using the Express Security Page
Follow these steps to create an SSID using the Express Security page:
Step 1 Type the SSID in the SSID entry field. The SSID can contain up to 32 alphanumeric characters.
Step 2 To broadcast the SSID in the wireless device beacon, check the Broadcast SSID in Beacon check box. The Broadcast SSID in Beacon setting is active only when the access point/bridge is in the Root AP mode. When you broadcast the SSID, devices that do not specify an SSID can associate to the access point/bridge when it is a root access point. This is a useful option for an SSID used by guests or by client devices in a public space. If you do not broadcast the SSID, client devices cannot associate to the access point unless their SSID matches this SSID. Only one SSID can be included in the beacon.
Step 3 (Optional) Check the Enable VLAN ID check box and enter a VLAN number (1 through 4095) to assign the SSID to a VLAN. You cannot assign an SSID to an existing VLAN.
Step 4 (Optional) Check the Native VLAN check box to mark the VLAN as the native VLAN.
Step 5 Select the security setting for the SSID. The settings are listed in order of robustness, from No Security to WPA, which is the most secure setting. If you select EAP Authentication or WPA, enter the IP address and shared secret for the authentication server on your network.
Note If you do not use VLANs on your wireless LAN, the security options that you can assign to multiple SSIDs are limited. See the "Using VLANs" section for details.
Step 6 Click Apply. The SSID appears in the SSID table at the bottom of the page.

Using the IP Setup Utility
IPSU enables you to find the access point/bridge's IP address when it has been assigned by a DHCP server. access point/bridge. This section explains how to download the utility from Cisco.com and install it, how to use it to find the access point/bridge's IP address.
Note IPSU can be used only on the following operating systems: Windows 95, 98, NT, 2000, ME, or XP.
Obtaining and Installing IPSU
IPSU is available on the Cisco web site. Follow these steps to obtain and install IPSU:
Step 1 Use your Internet browser to access the Cisco Software Center at the following URL:
Step 2 Click Option #2: Aironet Wireless Software Display Tables. The Wireless Software page appears.
Step 3 Click Cisco Aironet 1300 Series. The Software Download page appears.

Step 8 Double-click Setup.exe and follow the steps provided by the installation wizard to install IPSU.
The IPSU icon appears on your computer desktop.
Using IPSU to Find the Access Point/Bridge's IP Address
If your bridge receives an IP address from a DHCP server, you can use IPSU to find its IP address. Because IPSU sends a reverse-ARP request based on the bridge MAC address, you must run IPSU from a computer on the same subnet as the bridge. Follow these steps to find the bridge's IP address:
Step 1 Double-click the IPSU icon on your computer desktop to start the utility. The IPSU screen appears (see Figure 2-5).
Figure 2-5 IPSU Get IP Address Screen
Step 2 When the utility window opens, make sure the Get IP addr radio button in the Function box is selected.
Step 3 Enter the access point/bridge's MAC address in the Device MAC ID field. The access point/bridge's MAC address is printed on the label on the bottom of the unit. It should contain six pairs of hexadecimal digits. Your access point/bridge's MAC address might look like the following example:
Note The MAC address field is not case-sensitive.
Step 4 Click Get IP Address.
Step 5 When the access point/bridge's IP address appears in the IP Address field, write it down.
Using a Telnet Session to Access the CLI
Follow these steps to browse to access the CLI using a Telnet session. These steps are for a PC running Microsoft Windows with a Telnet terminal application. Check your PC operating instructions for detailed instructions for your operating system.
Step 1 Select Start > Programs > Accessories > Telnet.
If Telnet is not listed in your Accessories menu, select Start > Run, type Telnet in the entry field, and press Enter.
Step 2 When the Telnet window appears, click Connect and select Remote System.
Note In Windows 2000, the Telnet window does not contain drop-down menus. To start the Telnet session in Windows 2000, type open followed by the access point/bridge's IP address.
Step 3 In the Host Name field, type the access point/bridge's IP address and click Connect.
Resetting the Access Point/Bridge to Default Settings
You can use the web-browser interface or the CLI to reset the access point/bridge to a factory default configuration.
Note The following steps reset all configuration settings to factory defaults, including passwords, WEP keys, the IP address (if desired), and the SSID.
Using the Web-Browser Interface
Follow the steps below to delete the current configuration and return all access point/bridge settings to the factory defaults using the Web-browser interface.
Step 1 Open your Internet browser.
Step 2 Enter the access point/bridge's IP address in the browser address or location line and press Enter. An Enter Network Password screen appears.
Step 3 Enter your username (default Cisco) in the User Name field.
Step 4 Enter the access point/bridge password (default Cisco) in the Password field and press Enter. The Summary Status page appears.
Step 5 Click System Software and the System Software screen appears.
Step 6 Click System Configuration and the System Configuration screen appears.
Step 7 Click one of the following:
a. Reset to Defaults—resets all settings to factory defaults, including the IP address.
b. Reset to Defaults (Except IP)—resets all settings except the IP address to factory defaults.
Step 8 Click Apply.
Step 9 Click Restart.
Step 10 After the access point/bridge reboots, you can reconfigure the access point/bridge by using the Web-browser interface or the CLI (refer to the Cisco IOS Software Configuration Guide for Cisco Aironet Bridges or to the Cisco IOS Software Configuration Guide for Cisco Aironet Access Points).
Using the CLI
You should never delete any of the system files prior to resetting defaults or reloading software.
If you want to reset the access point/bridge to its default settings and a static IP address, use the write erase or erase /all nvram command. If you want to erase everything including the static IP address, in addition to the above commands, use the erase and erase boot static-ipaddr static-ipmask command.
From the privileged EXEC mode, you can reset the access point/bridge configuration to factory default values using the CLI by following these steps:
Step 1 Enter erase nvram: to erase all NVRAM files including the startup configuration.
Note The erase nvram command does not erase a static IP address.
Step 2 Follow the step below to erase a static IP address and subnet mask. Otherwise, go to step 3.
a. Enter erase boot static ip-address static-ipmask.
Step 3 Enter Y when the following CLI message displays: Erasing the nvram filesystem will remove all configuration files! Continue? [confirm].
Step 4 Enter reload when the following CLI message displays: Erase of nvram: complete. This command reloads the operating system.
Step 5 Enter Y when the following CLI message displays: Proceed with reload? [confirm].
Do not interrupt the boot process to avoid damaging the configuration file. Wait until the access point/bridge Install Mode LED begins to blink green before continuing with CLI configuration changes. You can also see the following CLI message when the load process has finished:
Line protocal on Interface Dot11Radio0, changed state to up.
Step 6 After the access point/bridge reboots, you can reconfigure the access point/bridge by using the Web-browser interface if you previously assigned a static IP address, or the CLI if you did not.
The access point/bridge is configured with the factory default values including the IP address (set to receive an IP address using DHCP). To obtain the access point/bridge's new IP address, you can use the show interface bvi1 CLI command.
