Port number (portNumber) of the local clock's parent gPTP
port number.
If this time-aware system is the grandmaster, the value
is the gPTP portNumber of this time-aware system.
If this time-aware system is not the grandmaster, the
value is the portNumber of the MasterPort (see
Table 10-1) of the gPTP communication path attached to
the single gPTP slave port of this time-aware system.
