Configuring the SyncE Function on the Device Where an Atom GPS Module Houses
To achieve network-wide clock synchronization, the SyncE function needs to be configured on a device where the Atom GPS module houses so that clock signals can be transmitted to downstream devices.
Procedure
- Run system-view
The system view is displayed.
- Run interface interface-type interface-number
The interface view is displayed.
- Run clock synchronization enable
Clock synchronization is enabled for the interface.
- Run clock priority priority-value
A priority is configured for the clock reference source of the interface.
- Run quit
Return to the system view.
- (Optional) Run clock ssm-control { on | off }
The device is configured whether to select a clock source based on SSM levels.
After SSM control is enabled, to use the enhanced SSM level as the information for clock source selection, run the clock enhanced-ssm-control {on | off} command to enable enhanced SSM. For details, see the page Ehanced SSM.
- (Optional) Run clock run-mode { free | hold | normal }
An Ethernet Equipment Clock (EEC) running mode is configured.
- (Optional) Run clock switch { revertive | non-revertive }
A clock recovery mode is configured.
- (Optional) Run clock wtr wtr-time
A clock WTR time is configured.
- (Optional) Run clock source-lost holdoff-time holdoff-time-value
A clock holdoff time upon a timing signal failure is configured.
- (Optional) Run clock max-out-ssm { prc | ssua | ssub | sec | prtc | eprtc | esec | eprc }
The maximum output SSM level is configured for the interface clock source.
- (Optional) Run clock freq-deviation-detect enable
Clock frequency offset detection is enabled.
- (Optional) Run clock input-threshold { dnu | prc | sec | ssua | ssub | prtc | eprtc | esec | eprc }
A lower quality threshold of external clock signals is specified.
