OID Name Value Type Description
19.xx12.4 Servo State <Enum>
0. Disabled
1. ---
2. Waiting Sync Sec
(+)
3. Waiting Sync Sec

4. Error
5. Frequency estim-

6. Tracking
7. Not updated
8. Locked
State of the PTP servo. For a port set as slave, the
servo should reach the “Locked” state to prop-
erly perform the synchronization. NOTE: The
state “---” has been created for PTP master ports
because for this mode the servo state is irrel-
evant.
19.xx12.12 Mode of
Operation
<Enum>
0. Two Step
1. One Step
2. Disabled
Reports the current mode of operation received
from the master. Two steps=Sync+FollowUp,
One step=Sync
19.xx12.26 Rx Sync Pack-
ets
<Integer> Number of received sync messages (Incre-
menting for Slave instances)
19.xx12.31 Tx Sync Pack-
ets
<Integer> Number of transmitted sync messages (Incre-
menting for Master instances)
19.xx12.28 Rx DelayReq
Packets
<Integer> Number of received delay request message
(Incrementing for Master instances)
19.xx12.33 Tx DelayReq
Packets
<Integer> Number of received delay request message
(Incrementing for Slave instances)
Then if a specific interface is not disabled (Port State ≠ None), by clicling on the (+) a user
will expand the interface to its Advanced View to get more information about the PTP
exchange. The bi-directional exchanges of PTP is resumed in "Simplified PTP packets
exchange for delay measurement (1) End-to-end (2) Peer-to-peer." on page67, where
the number of packets for each type of messages is provided by the parameters in
advanced view (see the table below).

19.xx12.2 Calculated
Offset
<Decimal> (f64) The value represents the actual offset (in
seconds) between master and slave. It is cal-
culated from the retrieved timestamps with cor-
rections from calibrations & asymmetries
settings.
19.xx12.3 One-Way
Delay
<Decimal> (f64) One-way path delay in seconds (equivalent to
delay_MS)
