The PTP Statistics Panel

This panel provides statistics for each Ethernet port. If the PTP is set to OFF for a
specific port, this screen will not display any information.

Peer Delay Req Rate: (Peer Delay Mechanism Only). Interval between
request messages sent between peers.
Best Master Clock Algorithm: [On or OFF] Only available with Multicast
and Hybrid modes. When set to ON, the Master will listen for traffic from
other Masters and become passive if another master on the network has
better credentials according to the Best Master Clock Algorithm (Section
9.3 of IEEE 1588-2008). A passive master will not transmit any protocol
messages as long as another Master is active as the Best Master on the net-
work. If the unit is synchronized but the oscillator is not yet locked to the
primary reference, then the BMCA will transition to slave until the end of
that condition.
When set to OFF, the Master will act as an active master no matter whether
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
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.
Peer MAC Address: [default: 01:80:C2:00:00:0E] Power Utility 61850-9-3
and Power System C37.238 profiles only.
Alt Timescale Display
(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.
