Setting the time information for the WLAN controller

The management of APs in a WLAN infrastructure is based upon the automatic distribution of certificates via the Simple Certificate Enrollment Protocol (SCEP).

The WLC can only check the temporal validity of these certificates if it is set with the current time. If the time is not set in the WLC, the WLAN LED illuminates in red and the device is not operational.

Note: Routers with the WLC option do not have a WLAN LED.

To set the time in the device start LANconfig, click on the entry for the WLC with the right-hand mouse key and select Set date/time from the context menu. Alternatively in WEBconfig you can click on Extras and then Set date and time.

Note: Alternatively, WLCs can automatically retrieve the current time from a time server by means of the Network Time Protocol (NTP). Information on NTP and its configuration can be found in the LCOS reference manual.

As soon as the WLC has valid time information it begins with the generation of the certificates (root and device certificate) and it determines a random number. Once the necessary certificates have been generated, the WLC indicates that it is operational and the WLAN LED blinks red.

Note: Once operational, you should make a backup copy of the certificates (Backing up the certificates)
