Shutting Down and Reloading the Wireless LAN Solution Engine

The following sections describe how to shut down, reload, and re-configure the WLSE.

Reloading the Wireless LAN Solution Engine

The WLSE can be shut down using either the Web interface or the CLI. Reloading the system starts the management services installed on the system, even if they were stopped prior to the reboot. To restart the WLSE using the Web interface, perform the following steps:


Step 1 Select Administration > Appliance > Status > Restart. The Restart System dialog box appears.

Step 2 Click Yes. The WLSE will restart.


To restart the system using the CLI, enter the reload command. The login prompt appears when the reboot is complete. For more information about the reload command, see the User Guide for the CiscoWorks 1105 Wireless LAN Solution Engine. You can access a PDF version of this guide by clicking View PDF in the WLSE's online help.

Shutting Down the Wireless LAN Solution Engine

To shut down the WLSE enter the shutdown command at the CLI prompt before powering off the WLSE. If you power off the WLSE without entering this command, you might disable the system. For more information about the shutdown command, see the User Guide for the CiscoWorks 1105 Wireless LAN Solution Engine. You can access a PDF version of this guide by clicking View PDF in the WLSE's online help.

Reconfiguring the Wireless LAN Solution Engine

To erase the system configuration and reboot the system, enter the erase config command at the CLI prompt. After the system reboots you must reconfigure the system using the setup program, as described in the "Configuring the Wireless LAN Solution Engine" section. For more information about the erase config command, see the User Guide for the CiscoWorks 1105 Wireless LAN Solution Engine. You can access a PDF version of this guide by clicking View PDF in the WLSE's online help.

Setting System Date and Time

The WLSE uses Universal Coordinated Time (UTC) for keeping the time and date. The WLSE uses the client's local time to display the time and date when connected via the Web interface. It uses UTC to display the time and date when connected via Telnet or a console, or when viewing log files.

You can set and maintain the system date and time using either of two methods:

Use the ntp server CLI command to assign one or more network time protocol (NTP) servers with which the system will synchronize its date and time. This method is recommended. For more information, see the "Setting Date and Time Using NTP" section.

Use the clock CLI command to set the date and time manually, updating it as needed. For more information, see the "Setting Date and Time Manually" section.

To display the system time, enter the show clock command. For more information on the show clock command, see the User Guide for the CiscoWorks 1105 Wireless LAN Solution Engine. You can access a PDF version of this guide by clicking View PDF in the WLSE's online help.

Setting Date and Time Using NTP

NTP is the recommended method for configuring time and date on the system. If your network uses NTP to set the date and time on devices, enter the following command in the CLI to designate an NTP server for the system to use to set the system clock:

# ntp server ip-address

where ip-address is the IP address of an NTP server.

For more information on the ntp server command, see the User Guide for the CiscoWorks 1105 Wireless LAN Solution Engine. You can access a PDF version of this guide by clicking View PDF in the WLSE's online help.

If you disable NTP, set the system clock to UTC manually as described in the "Setting Date and Time Manually" section. If you do not set the system clock manually after disabling NTP, the system clock might become inaccurate when the system is rebooted.

Setting Date and Time Manually

If your network does not use NTP to set the system time on devices and the time is not set correctly, set the date and time to UTC manually by entering the following command in the CLI:

# clock set hh:mm:ss month day year

where hh:mm:ss is the current time (for example, 13:32:00), month is the current month (for example, January, February), day is the day of the month (for example, 31), and year is the current year (for example, 2001).

For more information on the clock command, see the User Guide for the CiscoWorks 1105 Wireless LAN Solution Engine. You can access a PDF version of this guide by clicking View PDF in the WLSE's online help.

Configuring the Ethernet Ports

The WLSE uses 10/100 Mbps Ethernet connectors. The Ethernet 0 interface is configured when the WLSE is configured. To enable or change an additional interface configuration, enter the interface command in the CLI. For more information on the interface command, see the User Guide for the CiscoWorks 1105 Wireless LAN Solution Engine. You can access a PDF version of this guide by clicking View PDF in the WLSE's online help.

Any of the WLSE's Ethernet ports can be individually configured to allow connections via the following protocols:

Cisco Discovery Protocol (CDP)

Hypertext transfer protocol (HTTP)

Hypertext transfer protocol secure (HTTPS)

Internet Control Message Protocol (ICMP)

Secure shell (SSH) 1 and 2

Simple network management protocol (SNMP)

Telnet

To enable CDP on an individual Ethernet port, use the cdp command.To disable any of the other protocols listed above on an individual Ethernet port, use the firewall command. For more information about these commands, see the User Guide for the CiscoWorks 1105 Wireless LAN Solution Engine. You can access a PDF version of this guide by clicking View PDF in the WLSE's online help.

Configuring Email

To ensure that email arrives at its proper destination, use the mailroute CLI command. For more inform on the mailroute CLI command, see the User Guide for the CiscoWorks 1105 Wireless LAN Solution Engine. You can access a PDF version of this guide by clicking View PDF in the WLSE's online help.

Administering Management Services

The WLSE allows you to administer all management services at once. All commands that affect management services affect all of them at once; the logs that collect services information collect information about all of them.

You can stop and restart the management services if the system is not responding correctly to a management application. This should cause the services to reset and function properly again. Management services are restarted automatically when you reboot.

To stop management services, enter the following command in the CLI:

# services stop

To start management services, enter the following command in the CLI:

# services start

To view management services status, enter the following command in the CLI:

# services status

For more information about the these commands, see the User Guide for the CiscoWorks 1105 Wireless LAN Solution Engine. You can access a PDF version of this guide by clicking View PDF in the WLSE's online help.

Viewing System Information

To view system information, use the show commands, such as show clock and show process. For more information about these commands, see the User Guide for the CiscoWorks 1105 Wireless LAN Solution Engine. You can access a PDF version of this guide by clicking View PDF in the WLSE's online help.

Using the Maintenance Image

The WLSE has an operating system image and a default system configuration (hereafter collectively called the maintenance image) stored in Flash memory. You can use the maintenance image to boot the system to perform some system administration tasks and disaster recovery.

You can run only the following commands while the system is running from the maintenance image: reload, erase config, and fsck.

For information about these commands, see the User Guide for the CiscoWorks 1105 Wireless LAN Solution Engine. You can access a PDF version of this guide by clicking View PDF in the WLSE's online help.

While the maintenance image is running, you can do the following tasks, which you cannot do when the system is booted from the disk:

Recover from loss of all administrative user account passwords.

Perform disk filesystem integrity checks.

Booting from the Maintenance Image

As a security measure, you can boot from the maintenance image only while connected to the system console.


Step 1 Connect a console to the WLSE's console port, and log on as admin.

Step 2 Reboot the system by doing one of the following:

Enter the reload CLI command to reload the system if it is running. For more information on the reload command, see the User Guide for the CiscoWorks 1105 Wireless LAN Solution Engine. You can access a PDF version of this guide by clicking View PDF in the WLSE's online help.

Power on the system, if it is powered off.

Power the system off and then back on if you cannot log in because you have lost all user account passwords.

Step 3 When the LILO boot: prompt appears, press the Tab key.

Step 4 When the boot: prompt appears, enter CiscoBreR.

Step 5 After you complete all necessary tasks, reboot the system by entering the reload command and allow the system to boot from the disk (the default boot order).


Recovering from Loss of All Administrator Passwords

If you cannot log into the system because you cannot remember the administrator account names or passwords, you can recover by booting from the maintenance image, erasing the existing configuration from Flash memory, and reconfiguring the system using the setup program.

To recover from the loss of all administrator passwords:


Step 1 Boot the system from the maintenance image as described in the "Booting from the Maintenance Image" section.

Step 2 Enter the erase config command to erase the system configuration. The system reboots.

Step 3 Allow the system to boot from disk (the default boot order).

Step 4 Configure the system from the setup program, as described in the "Configuring the Wireless LAN Solution Engine" section.

Step 5 After the system reboots, reconfigure the WLSE by following the steps outlined in the "Installing the Wireless LAN Solution Engine" section.
