oscillator can thus be visualized under the active servo panel.
OID Name Value Type Description
1.1220.x act/servo Information about the active
servo instance
1.1220.1 Interface Name <String> Name of the network interface on
which the servo is running.
1.1220.6 State 0. Disabled
1. Adjusting Time
2. Adjusting Time
3. Adjusting Phase
4. Locked
5. Wait Stable Phase
6. Invalid
7. Undefined
8. Not Updated
9. Wait Time Adjust
10. Wait Phase Adjust
11. Initializing
Servo State: where ‘Locked’ cor-
responds to the legacy TRACK_
PHASE state and means that the cor-
responding interface is actively dis-
ciplining the device. Disabled is used
when the port is setup as Master or
does not receive any valid PTP/WR
exchange.
Note:
The 1st state corresponds to
adjustments in seconds order, and the
2nd one to adjustments in nano-
seconds order.
1.1220.5 Up Count <Integer> (u32) Number of updates for the servo. It is
typically increased by 1 each second.
1.1220.10 Mean Delay <Decimal> (f64)
Unit: s
Cable round trip time excluding
fixed+semistatic (cRTT).
1.1220.11 Delay MS <Decimal> (f64)
Unit: s
Calculated Delay between Master and
Slave considering asymmetry and
fixed delays.
1.1220.21 Egress Latency <Decimal> (f64)
Unit: ns
Fixed latency between the moment
when a PTP packet is timestamped to
its exit on the physical layer (i.e.,
optical fiber). Legacy: ’WR Slave ∆Tx’.
1.1220.20 Ingress Latency <Decimal> (f64)
Unit: ns
Fixed latency between the moment
when a PTP/WR packet ingresses
from the physical layer to its
timestamp. Legacy: ’WR Slave ∆Rx’.
5.3.2.2 Port Instance
A WR port instance is then associated to each network interface. The table displayed in the
following image provides a quick overview of the state of each interface.

The parameters shown are explained in the following table:
