Port Status
CHAPTER •
5 SecureSync User Reference Guide Rev. 18
Current Network Mask : The Network Mask currently being used by the PTP interface.
Current Gateway : The Gateway address currently being used by the PTP interface.
Port State : Reports the current state of the PTP State Machine:
Disabled : PTP Ethernet port is Disabled. See PTP Setup/Network page, PTP Net-
work Settings options.
Initializing : Ethernet link is unplugged/PTP Module is in power-up state. A Master
Clock doesn't leave this state while it can't get the current time and synchronization
references from SecureSync to synchronize with it.
Listening : PTP module is looking for a Master Clock.
Master : PTP Master has become the active Master Clock on the network.
Passive : PTP Module has become a Passive Master Clock. (There is another
Master Clock on the network with better quality or higher priority). This Master will
wait until the Best Master Clock Algorithm determines it should become the best
Master Clock, and then it will transition to the Master Clock state.
Uncalibrated : PTP Slave has selected a Master Clock on the network attempts to
synchronize with it using sync packets.
One Step Mode : Determines the number of steps in the PTP protocol. Will be one
of the following:
Disabled : Two-Step Mode is enabled
Enabled : One-Step Mode is enabled
[Default=Disabled]
NOTE –
Mechanism.
The current implementation of one- step mode involves a software oriented
timestamping. The two-step mode imlements a hardware oriented timestamping,
insensitive to software execution time variations. The Two- step mode is recom-
mended, as it increases the PTP Clock's accuracy
Delay Mechanism : Will be one of the following:
E2E : End-to-End Delay Mechanism
P2P : Peer-to-Peer Mechanism
Disabled : No Delay Mechanism
Default setting: E2E
One-Step Mode is not supported with the Peer-to-Peer Delay
