I want to synchronise a WLC2006 with a NTP server. After having set the NTP server IP address with the GUI, the ping operates properly, but the WLC keeps the date and time set manually. The NTP server is connected to the port supporting the dynamic interface carrying the data traffic (that means it is not connected to the port supporting the management and AP interfaces).
The NTP server looks operating properly: a MAR3200 and 2 AP1242 on the other side of the radio link are synchronised with this NTP server. The WLC is running the 220.127.116.11 release.
Do I miss a parameter configuration? Any link is welcome.
