PTP
Configuration
Having an inappropriate master can create strange network behavior for other devices.See
Connecting
to a PTP Source
(on page 26).
PTP Domain
The PTP domain number that the SNP will listen to. Choose a domain from
0 - 255 with a default of 127. Clocks that share a domain are synchronized
to each other.
Announce Interval
The announce interval is 2 to the power of this value in seconds. For
example, 0 is one second. The full range is -3 to 4, presented as follows:
•
8 Hz(-3)
•
4 Hz(-2)
•
2 Hz(-1)
•
1 Hz(0)
•
0.5 Hz(+1)
•
0.25 Hz(+2)
•
0.125 Hz(+3)
•
0.0625 Hz(+4)
The default is 0.
Announce Receipt Timeout
The number of announce Intervals that have to pass, before declaring a
timeout. The range is from 2 to 10, with a default of 10. The lower the
value, the faster SNP will failover to a redundant master. Select a higher
value for a stable clock regardless of network conditions.
PTP Timeout = AnnounceReceiptTimeout * announceInterval (in seconds
as defined above).
