or not other masters are present. This may be required for certain PTP pro-
files.
Clock Priority 1: [0 to 255] (0 is highest priority. Default is 128 for both pri-
ority values. This is usually the priority value that a Slave is set to.) See IEEE
1588-2008, Section 8.10.1, 8.10.2.
Clock Priority 2: [0 to 255] (same as above).
Network Transport: [Ethernet, IPv4/UDP, IPv6/UDP] Selects the transport
protocol used for PTP packets.
MAC Address: [default: 01:1B:19:00:00:00] Default, Power Utility 61850-9-3
and Power System C37.238 profiles only. The address protocol messages
are sent to.
Peer MAC Address: [default: 01:80:C2:00:00:0E] Default, Power Utility
61850-9-3 and Power System C37.238 profiles only.
Alt Timescale Display Name: Power System C37.238 profile only. Display
name of the alternative timescale (optional).
Multicast Ttl: [1 through 255] Time-to-live (packet lifespan) — Sets the TTL
field for PTP packets except for Peer-to-Peer packets for which TTL is
forced to 1 as specified in IEEE Std 1588-2008 Annex D.3.
Delay Asymmetry: [-2147483648 to 2147483648] Sets the time difference
(in nanoseconds) of the transmit and receive paths in networks with a con-
stant asymmetry (default of 0). The values should be positive when the
master-to-slave propagation time is longer and negative when the slave-
to-master time is longer.
The PTPDatasets Panel
The PTP Datasets Panel brings data from PTP communications to be
viewed via the Web UI. There are five dataset types available:
Default Dataset
TwoStepFlag, ClockIdentity, NumberPorts, ClockClass, ClckAccuracy, Off-
setScaledLogVarience, Priority1, Priority2, DomainNumber, and SlaveOnly.
Current Dataset
StepsRemoved, OffsetFromMaster, MeanPathDelay
