Advanced - PTP Profile Customized Settings
The settings become available with PTP profile set to ‘customized’.
Clock class PTP-clock’s class according to IEEE 1588 [read only]
Accuracy PTP-clock’s accuracy according to IEEE 1588 [read
only]
Clock domain PORT 1 PTP-clock’s domain at PORT 1
Clock domain PORT 2 PTP-clock’s domain at PORT 2
Priority 1 Priority setting for master announcement (the smaller
the value the higher the priority)
Priority 2 If value ‘Priority1’ (and other PTP-clock parameters) of
more than one device in the network match:
Priority setting for master announcement (the smaller
the value the higher the priority)
Announce Intervall of sending announce-packets for auto-
negotiation.
Sync Intervall of sending sync-packets to the PTP-clock
slaves in the network.
Min delay request Intervall of sending End-To-End packets of PTP-clock
slave to PTP-clock master. To determine the offset
slave-to-master.
Min pdelay request Intervall of sending Peer-To-Peer packets between
two PTP-clocks. To determine the offset master-to-
slave and slave-to-master.
Announce receipt
timeout Number of missed announce-packets (threshold) to
reinitialize the negotiation of PTP-clock master.
One step clock Timestamp of PTP-clock is integrated in PTP-sync-
packets. No follow-up packets are sent.
No = Two step clock is used
Slave only PTP-clock is always slave.
Delay mechanism E2E - Offset slave-to-master is determined by End-To-
End packets.
P2P - Offset master-to-slave and slave-to-master is
determined by Peer-To-Peer packets.
