| Value | Description |
FEATURE_PTP_STATUS_INITIALIZING | PTP state machine is initializing |
FEATURE_PTP_STATUS_FAULTY | PTP state machine has detected the PTP port as faulty |
FEATURE_PTP_STATUS_DISABLED | PTP state machine has (administratively) placed the port in Disabled state |
FEATURE_PTP_STATUS_LISTENING | PTP state machine is waiting for reports from other state machines |
FEATURE_PTP_STATUS_PREMASTER | PTP state machine is a Master candidate, and is waiting for reports from other state machines |
FEATURE_PTP_STATUS_MASTER | PTP state machine has selected this port as the PTP master for the network |
FEATURE_PTP_STATUS_PASSIVE | PTP state machine is not the master, nor is it synchronized to a master |
FEATURE_PTP_STATUS_UNCALIBRATED | PTP state machine has identified a master, and this port is attempting to synchronize to it |
FEATURE_PTP_STATUS_SLAVE | PTP state machine has selected this port as a slave to another (master) PTP state machine |
FEATURE_PTP_PARAM_STATUS is a whole number representing the FEATURE_PTP_STATUS_ enumerations shown above. The parameter will report on the status of the PTP state machine when the user performs a get on this feature.
Steady state values of this parameter are _STATUS_FAULTY (the clock is not functioning properly), _STATUS_DISABLED (the camera’s default state, but is otherwise only gets to this state via user direction), _STATUS_SLAVE (this clock is the slave to the connected (maser) clock), and _STATUS_MASTER (this clock is a master to all subtended clocks, and given our camera is a IEEE-1588 ordinary clock, we must be the domain grandmaster clock).
