NTP servers

To correctly operate with licenses and certificates, the Spectera Base Station needs a correct system time. The device will use the well-established NTP mechanism from the IP protocol stack to synchronize clock between a time server in a network and the client inside the device.

Currently for an IT administrator or system integrator it is not possible to manually configure a dedicated NTP server to be used by the Spectera Base Station. Being able to configure a dedicated NTP server manually is a planned feature for an upcoming release.

The device behaves the following way:

If a time server configuration has been provided via DHCP or manually, it tries to connect and sync to that time server first.
Otherwise the device is trying to access any server of following list of time server pools worldwide publicly available.

An IT administrator has to assure to provide Internet access to at least one of the server pools and to provides DNS settings via DHCP to the device.
