IEEE 1588v2 domain is 44 to 63.
IEEE 1588v2 domainIEEE 1588v2 domain
Touch the field to set the domain. The PTP messages and data sets are
associated with a domain and therefore the PTP protocol is independent for
different domains.
In multicast mode, review the attributes in the timing section when changing the domain.
Otherwise the best master algorithm may fail for all IEEE 1588v2 clocks in the domain.
Step modeStep mode
Select how to send the message for the time synchronization: One-stepOne-step and
Two-stepTwo-step.
One-stepOne-step: The timestamp of the time when the master send a Sync message is
inserted into the Sync message itself. Follow_up message is not sent.
Two-stepTwo-step: The timestamp of the time when the master send a Sync message is
inserted into the Follow_up message which follows the Sync message. For
Network Master, the same timestamp is inserted into both the Sync message
and the Follow_up message.
Delay mech.Delay mech.
Allows you to choose which mechanism to use for calculating the mean path

Slave modeSlave mode
If the check box is selected, the port can only act as a slave clock. Used in both
multicast (normal) and unicast mode.
UnicastUnicast
Used to enable the unicast profile. For domains 0 to 3 static unicast is enabled.
For domains 4 to 23 the Telecom Profile (ITU-T G.8265.1 IEEE 1588 v2 profile
for telecommunication) is used.
If Slave modeSlave mode is checked, the clock of the Network Master will always run as a slave in
both normal and unicast mode.
If Slave modeSlave mode is not checked in normal mode, the best master clock algorithm is run and
the result of this will determine if the Network Master can become a grandmaster clock.
In UnicastUnicast mode, if the Slave modeSlave mode is not checked, the Network Master will become a
grandmaster clock.
Unicast negotiateUnicast negotiate
Selecting the check box enables the unicast negotiation. This check box is
available when Profile is set to User DefinedUser Defined and the UnicastUnicast is selected.
Clock tabClock tab
The ClockClock tab contains the parameters related to the grand master clock-
specific setup. Note that only ID can be set if the port is set in Slave Mode.
