Hybrid clocking

OS10 supports hybrid clocking, where Synchronous Ethernet (SyncE) is used to synchronize frequency and PTP is used to synchronize phase and Time of Day (ToD).

Use the ptp clock boundary hybrid command to enable hybrid clocking on the system-default profile. Hybrid clocking is applicable only for PTP boundary clock.

When PTP clock is configured in the hybrid mode, any change in the SyncE frequency lock status affects the PTP clock synchronization. Also, the PTP clock is synchronized only when the frequency is locked to a clock source.

OS10 supports hybrid clocking only on the following platforms:

  • S5200-ON series: S5224F–ON, S5232F-ON, S5248F-ON, S5296F-ON
  • Z9264F-ON

For more information about SyncE, see Synchronous Ethernet.
