PTP Accuracy

jitter.
This setting only needs to be changed if a network switch without PTP support is being
used and more jitter is acceptable.
Interaction between different time synchronization types in complex set-ups may induce a
xed accuracy.
Use Accurate Master
Ensure that “accurate master”’ setting is disabled.
PTP Role (read-only)
Verify that the PTP Role is slave. If Master is listed in this column, the GEN series
mainframe itself is the master rather than the GMR1000.
Clock Class
The clock class should be 13 (GPS clock class if the GPS antenna is synchronized).
If the clock class is 7, the GPS antenna is currently not locked and runs on its internal
clock.
If the clock class is 52, the GPS antenna was never synchronized.
PTP Master MAC-address
This is the GMR1000 MAC-address, or the boundary clock MAC-address when bound-
ary clocks are used.
