Chapter 2 Using the Management Interfaces

Using SNMP

Applying Changes to the Configuration

The CLI’s auto-apply feature is on by default, so changes you make to any page are applied automatically when you move to another management page. To apply changes and stay on the current page, type apply and press Enter.

Using a Telnet Session

Follow these steps to browse to the CLI pages with Telnet:

Step 1 On your computer’s Start menu, select 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 pull-down menus. To start the Telnet session in Windows 2000, type open followed by the access point’s IP address.

Step 3 In the Host Name field, type the access point’s IP address and click Connect.

Note Access point firmware 12.00T and above supports Secure Shell (SSH) sessions. See the “Using Secure Shell” section on page 11-5for more information.

Using SNMP

You use an SNMP management application to configure the access point with SNMP. Follow these steps to configure the access point with SNMP:

Step 1 Compile the MIB you need to use in your SNMP management application. MIBs supported by the access point are listed in Supported MIBs.

Step 2 Use a web browser, a Telnet session, or the console interface to open the Express Setup page in the access point management system.

Step 3 Enter an SNMP community name in the SNMP Admin. Community field and click OK or Apply.

Step 4 Follow this link path to reach the SNMP Setup page:

a.On the Summary Status page, click Setup.

b.On the Setup page, click SNMP in the Services section of the page.

Use the SNMP Setup page to enter detailed SNMP settings, such as the SNMP trap destination. See the “SNMP Setup” section on page 11-2for details on the SNMP Setup page.
