ClockIdentity
Clock identifier (clockIdentity) of the local clock's
parent clock. The default value is set to
ieee8021AsDefaultDSClockIdentity.
If this time-aware system is the grandmaster, the value
is the clockIdentity of this time-aware system.
If this time-aware system is not the grandmaster, the
value is the clockIdentity of the MasterPort (see
Table 10-1) of the gPTP communication path attached to
the single slave port of this time-aware system.
