Master: PTP Master has become the active Master Clock on the net-
work.
Passive: PTP Module has become a Passive Master Clock. (There is
another Master Clock on the network with better quality or higher pri-
ority). 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
Will be one of the following:
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 vari-
ations. The Two-Step Mode is recommended, as it increases the PTP
Clock's accuracy
Delay

Mode: Determines the number of steps in the PTP protocol.
Disabled: Two-Step Mode is enabled
Enabled: One-Step Mode is enabled
[Default=Disabled]
Note: One-Step Mode is not supported with the Peer-to-
Peer Delay Mechanism.
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
