4 Installing the D-Link Unified Access System
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
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 WLAN Controller Switch communicates
with the APs it manages by using Secure Sockets Layer (SSL)
connections. The first time you power on the WCS, 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.
For information about how to configure a loopback interface and enable
routing, see “D-Link WLAN Controller Switch with Routing Enabled” on
page 61.
IP Address 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 WCS features.
AP Authentication 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.
Country Code 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.
