In order for the Unified Switch to be able to discover and manage access points, the WLAN switch and its operational status must both be enabled. The WLAN component is enabled by default.
When you access the switch user interface, make sure you set the correct country code for the switch so that the access points can only operate in the modes permitted in your country. The default country code is US for operation in the United States.
NOTE:Wireless features are available under the WLAN tab on the navigation menu.
NOTE:Most configuration pages have a Submit button, which applies the changes to the running configuration but does not save them to non-volatile memory (NVRAM). To make the changes permanent so they persist across a reboot,click the Tool, then click Save Changes to navigate to the appropriate page.You can also use the write command in Privileged Exec mode.
Basic Wireless Global Configuration
1.Enable WLAN Switch
Check the box to enable WLAN switching functionality on the system. Clear the check box to administratively disable the WLAN switch.
If you clear the check box, all peer switches and APs that are associated with this switch are disassociated.
Disabling the WLAN switch does not affect non-WLAN features on the switch, such as VLAN or STP functionality.
2.WLAN Switch Operational Status
Shows the operational status of the switch. The status can be one of the following values:
If the status is pending, click Refresh to refresh the screen.
3.WLAN Switch Disable Reason
If the status is disabled, this field appears and one of the following reasons is listed:
• None—The cause for the disabled status is unknown.
• Administrator disabled—The Enable WLAN Switch check box has been cleared.
• No IP Address—The WLAN interface does not have an IP address.
• No SSL Files—The D-Link Unified Switch communicates with the APs it manages by using Secure Sockets Layer (SSL) connections. The first time you power on the Unified Switch, it automatically generates a server certificate that will be used to set up the SSL connections. The SSL certificate and key generation can take up to an hour to complete.
If routing is enabled on the switch, the operational status might be disabled due to one of the following reasons:
• No Loopback Interface—The switch does not have a loopback interface.
• Global Routing Disabled—Even if the routing mode is enabled on the WLAN switch interface, it must also be enabled globally for the operational status to be enabled.
This field shows the IP address of the WLAN interface on the switch. If routing is disabled, the IP address is the network interface. If routing is enabled, this is the IP address of the routing or loopback interface you configure for the Unified Switch features.
Select the check box to require APs to be authenticated before they can associate with the switch.
AP MAC Validation
Select the database to use for AP validation.
• Local—If you select this option, you must add the MAC address of each AP to the local Valid AP database.
• RADIUS—If you select this option, you must configure the MAC address of each AP in an external RADIUS server.
Select the country code for the country where your switch and APs operate.A popup window asks you to confirm the change.
Wireless regulations vary from country to country. Make sure you select the correct country code so that your WLAN system complies with the regulations in your country. Some WLAN modes, such as the Atheros modes, are not available in some countries.
Changing the country code disables and re-enables the switch. Any channel and radio mode settings that are invalid for the regulatory domain are reset to the default values.
The country code (IEEE 802.11d) is transmitted in beacons and probe responses from the access points.
From the CLI, you can view the same information that is available on the Wireless Global Configuration page with the show wireless command in Privileged EXEC mode. If you need to change the country code, you can view the list of available countries and their twoletter codes with the show wireless country-code command.
The CLI commands to set the country code and enable the WLAN switch are available in Wireless Config mode. To set the country code, enter country-code
. To enable the WLAN switch, enter enable. The following example shows how to access Wireless Config mode, set the country code to Canada, and enable the WLAN switch.
