Operation mode
Use this list box to select the operating mode for the PTP clock
according to IEEE 1588-2008 (
One step
or
Two step
).
One step is the recommended mode since this mode produces less
network traffic. The two step mode should only be used if some
equipment used in the network does not work correctly with the one
step mode.
User description
Enter a description for your
OTMC 100
. This may be required to
identify the
OTMC 100
device uniquely if you are using more than
one
OTMC 100
device in the network.
PTP management interface

interface.

Priority 1
Priority 2
Use this field to specify the priority values. To each PTP master
clock, two priority values (Priority 1 and Priority 2) may be assigned
by the user. If more than one PTP grandmaster clock is available in
the network, a clock with a lower Priority 1 value will always be a
preferred master clock over a clock with a higher Priority 1 value (see
IEEE 1588-2008, clause 6.6.2.3). A value in the range from 0 to 255
may be assigned to the Priority 1 parameter (see IEEE 1588-2008,
clause 7.6.2.2).
The Priority 2 parameter (see IEEE 1588-2008, clause 7.6.2.3) is
used if several devices have the same Priority 1 parameter value and
the same clock quality (class, accuracy and variance). The Priority 2
parameter thus allows a finer grained ordering among otherwise
equivalent clocks (see IEEE 1588-2008, clause 6.6.2.3). Lower
values take precedence.
