The information in the PTP status page is displayed in four panes.
7.2.2.1 Port pane
The Port pane displays information on the current state and configuration of the OTMC 100 PTP port.
The data listed here correspond to the Port Dataset specified in IEEE 1588-2008, clause 8.2.5.
Port state
40
Displays the current PTP state of the network port of OTMC 100.
Possible states are: Master, passive, listening, disabled, faulty.
See IEEE 1588-2008, clause 9.2.5 for more detailed information.
Master: OTMC 100 is the best master clock in the network (according to
the BMCA) and is thus used as time reference (PTP grandmaster clock).
Passive: Another PTP clock in the network is the best master clock
according to the BMCA (e.g., has a higher priority or provides more
accurate time). Therefore, the other clock is used as time reference in
the network.
Listening: After initialization OTMC 100 is listening for messages from
other PTP master clocks in the network before it becomes either master
or passive.
Disabled: The PTP state machine of OTMC 100 has been disabled via
the management interface.
Faulty: OTMC 100 detected a fault condition. Further details about the
error can be found in the log file.
