Chapter 4 Configuring Controller SettingsWireless Device Access
Managing the System Time and Date
Step 15 Enter the WLAN 1 SSID, or network name. This is the default SSID that lightweight access points use
to associate to a controller.
Step 16 Allow or disallow Static IP Addresses for clients. Enter yes to allow clients to supply their own IP
addresses. Enter no to require clients to request an IP Address from a DHCP server.
Step 17 If you need to configure a RADIUS Server, enter yes, and enter the RADIUS server IP address, the
communication port, and the shared secret. If you do not need to configure a RADIUS server or you want
to configure the server later, enter no.
Step 18 Enter a country code for the unit. Enter help to list the supported countries.
Note When you run the wizard on a wireless controller network module installed in a Cisco Integrated
Services Router, the wizard prompts you for NTP server settings. The controller network module
does not have a battery and cannot save a time setting. It must receive a time setting from an NTP
server when it powers up.
Step 19 Enable and disable support for 802.11b, 802.11a, and 802.11g.
Step 20 Enable or disable radio resource management (RRM) (auto RF).
When you answer the last prompt, the controller saves the configuration, reboots with your changes, and
prompts you to log in or to enter recover-config to reset to the factory default configuration and return
to the wizard.
Managing the System Time and Date
You can configure the controller to obtain the time and date from a Network Time Protocol (NTP) server,
or you can configure the time and date manually.
Configuring the Time and Date Manually
On the CLI, enter show time to check the system time and date. If necessary, enter
config time mm/dd/yy hh:mm:ss to set the time and date.
To enable Daylight Saving Time, enter config time timezone enable.
Configuring an NTP Server
Each NTP server IP address is added to the controller database. Each controller searches for an NTP
server and obtains the current time upon reboot and at each user-defined polling interval (daily to
weekly).
On the CLI, enter config time ntp server-ip-address to specify the NTP server for the controller. Enter
config time ntp interval to specify, in seconds, the polling interval.
Note For access points to successfully join a Cisco WLAN controller, Cisco recommends that you configure
the controller to obtain the time from an NTP server.
