Using the Setup Program

Configure the WLSE when you boot the system for the first time, and whenever you manually erase the configuration using the erase config CLI command. For more information about this command, see "Using CLI Commands."

Press the Backspace key or the Delete key to delete characters when entering a response to a prompt.


Note You cannot edit a response after you press the Enter key. To change an entered response, you must exit the setup program, run erase config, and rerun the setup program.


You can exit the setup program in two ways:

Press Ctrl-c.

The login prompt appears. Log in as the user setup to run the setup program.

Enter no at the final prompt:

Would you like to save this configuration? [yes].

The setup program exits without saving the configuration, then restarts.

To configure the WLSE, perform the following steps:


Step 1 Attach a console to the console port and power on the WLSE:

For the WLSE 1105, use the serial port on the front panel; do not use the serial port on the back panel as the console port.

For the WLSE 1130, use the serial port on the back panel as the console port.

When the system finishes booting, a login prompt appears on the console.

Step 2 At the login prompt, enter setup.

When you boot the system for the first time, it is not configured. Logging in as setup allows you to configure the system.

Step 3 Enter responses to the first set of prompts to configure the WLSE's connectivity. Table 3-2 describes how to respond to the prompts. After inputting the required information, press Enter to proceed to the next prompt.

Step 5 After you finish configuring the Wireless LAN Solution Engine, it will reboot. After it finishes rebooting, set up your mail server to send mail to external domains by entering the following command:

mailroute {hostname | ip-address}

where hostname is the hostname of the SMTP server and ip-address is the IP address of the SMTP server. If you do not set the mail server, email can only be sent to the local domain. For more information about this command, see mailroute.


To change the information in the setup configuration, use the following CLI commands. For more information about these commands, see "Using CLI Commands."

To change the host name, use the hostname command.

To change the domain name, use the ip domain-name command.

To change the DNS server, or add up to 2 additional DNS servers, use the ip name-server command.

To configure or reconfigure an Ethernet port, use the interface command.


Tip To change any other part of the WLSE's setup configuration, use the erase config command to erase the previous configuration, and run the setup program again.


Configuring Name Resolution

The WLSE resolves host names by using a Domain Name System (DNS) server, or you can use the import CLI command to add individual hosts or a UNIX-style hosts file. If you are using a DNS server, register the system on a DNS server. Use the WLSE's host name as its DNS name. For information on the import command, see import.

The WLSE does not require name resolution, but if name resolution is not used, the following problems will occur:

Host names will not resolve.

Discovery will be slow.

Connecting to the WLSE via Telnet will be slow. You will be able to connect to the WLSE only after name resolution on the client times out.

Ping and traceroute commands will result in 100% packet losses in 4 out of 5 ICMP packets. This occurs because the WLSE times out when attempting reverse DNS lookup.

IP addresses will appear in host name columns.

Configuring the WLSE Without a DNS Server

If you are not using a DNS server, perform the steps described in Using the Setup Program, with the following exception:


Step 1 At the DNS server ip address prompt, enter any IP address.

After you finish configuring the WLSE, erase the IP address you entered by entering the following command:

no ip name-server ip-address

where ip-address is the IP address you entered at the DNS server ip address: prompt. For more information about this command, see ip name-server.


Verifying the Configuration

While at the console, verify that the WLSE is correctly configured by performing the following steps:


Step 1 At the system console, enter admin at the login prompt, and log in with the password you created during setup. You can also use Telnet or SSH to log in as the admin user.

If you need to attach a console:

For the WLSE 1105, use the serial port on the front panel; do not use the serial port on the back panel as the console port.

For the WLSE 1130, use the serial port on the back panel as the console port.


Note For security reasons, Telnet is disabled on the WLSE by default. If you want to be able to connect to the CLI interface using Telnet, you can enable it by using the telnetenable enable command. For information on this command, see telnetenable.


Step 2 If you are using a DNS server, enter the following command to verify that the WLSE can obtain DNS services from the network:

# nslookup dns-name

where dns-name is the DNS name of a host that is registered in DNS. If the system cannot obtain the IP address of the host from DNS, use the ip name-server command to specify a working DNS server. For more information on these commands, see nslookup and ip name-server.

Step 3 Enter the following command to verify that the system can communicate with the network:

# ping ip-address

where ip-address is the IP address of a host that is accessible on the network. A DNS server is a recommended host to ping because it should always be running and accessible. For more information on this command, see ping.

Step 4 Enter the show config command to verify that the configuration is as you expected. For more information on this command, see show config.

Step 5 Enter the show clock command to verify that the system time and date are correct in Coordinated Universal Time (UTC).

If the time or date is incorrect, set the correct time and date using the clock command.

If your network uses NTP, configure the system to use NTP to set the clock.

For more information about configuring time and date, see Setting WLSE Date and Time. For more information on these commands, see show clockand show clock.

Step 6 Enter the exit command to log out.


You are now finished using the console. The remaining steps take place at the client system.

Configuring the Web Browser

Before you connect to the WLSE Web interface, make sure you are using a supported browser and that the browser is properly configured.

Supported Browsers

Configuring Internet Explorer

Configuring Netscape Navigator

Supported Browsers
