Forcing a Specific Reference
The system synchronous timing output can be forced to use a specific reference.
Note: The debug sync-if-timing force-reference command should be used only to test and debug
problems. Once the system timing reference input has been forced, the system does not revert back
to another reference unless explicitly re-configured.
If the debug sync-if-timing force-reference command is executed, the current system synchronous
timing output is immediately referenced from the specified reference input. If the specified input is
not available (shut down) or in a disqualified state, the timing output enters a holdover state based
on the previous input reference.
Debug configurations are not saved between reboots.
