To use manual selection, set the selection_policy configuration option to manual, with a second parameter giving the name of the initial sync module instance to use. See Configuration Options.

Use the sfptpdctl utility program to change the instance selected as the master. This allows you to switch timesources simultaneously across an entire network, thus ensuring that all servers use a common timesource. See Daemon Control Mechanism.
