P2P (Peer-to-Peer) mechanism
If only PTP-capable components are installed in the network and they are config-
ured so that they can use the same mechanism, this setting can then be used to
detect the propagation delay.
Network Transport:
This settting is used to determine the communication layer in the network on which
the PTP synchronization occurs.
L2
The PTP synchronization occurs directly on the data link layer (OSI model layer
2).
UDPv4
The network layer (OSI model layer 3) is used for the synchronization. The com-
munication occurs via the ports 319 and 320.
Sync interval:
The time interval in which a synchronization telegram is to be sent. The specifica-
tion occurs in
2
𝑥
𝑠
; i.e. a value of 0 results in a time interval of 1s, since
2
0
𝑠 = 1𝑠
.
Domain number:
In order to operate several independent PTP clocks in one network, these can be
split up onto several domains. Only “slaves” that belong to the same domain refer to
the time of the PTP master clock available in the domain.
Status:
This is where general status information is shown.
Message Counters:
This is where information about synchronization messages is shown.
