Forcing a Specific Reference

You can force the system synchronous timing output to use a specific reference.
NOTE: The command should only be used to
debug sync-if-timing force-reference
test and debug problems. Once the system timing reference input has been forced, it will not revert
back to another reference unless explicitly reconfigured.
When the command is executed, the current system synchronous timing output is immediately
referenced from the specified reference input. If the specified input is not available (shutdown), or
in a disqualified state, the timing output will enter a holdover state based on the previous input
reference.
Debug configurations are not saved between reboots.
CLI Syntax: debug>sync-if-timing
force-reference {ref1 | ref2 | bits}
Example :
debug>sync-if-timing# force-reference
