General Configuration

Network Time Protocol (NTP) manages time and network clock synchronization within the network. NTP is a client or server implementation. Controllers, service platforms, and access points (NTP clients) periodically synchronize their clock with a main clock, which is an NTP server.

Select Devices > Host Name .
The Basic device configuration dashboard opens.

Select General and configure the following settings:


NOC Update Interval	Specify the interval at which statistical updates are sent by the RF Domain manager to its adopting controller (the NOC controller). Enter a value in the range 5–3600 (seconds), or enter 0 to invoke auto mode where the update interval is automatically adjusted by the controller based on load information. The default value is 0.
