The following error message displays when the you try to modify sync-if-timing parameters
without entering the keyword begin.

Configuring Timing References

Use the following CLI syntax to configure timing reference parameters. The source port
specified for ref1 and ref2 is dependent on the router model type and chassis slot. Please refer
to the details in the specific command descriptions.
The following displays a timing reference configuration example for the router:

Using the Revert Command

The revert command allows the clock to revert to a higher priority reference if the current
reference goes offline or becomes unstable. When the failed reference becomes operational,
it is eligible for selection.
When mode is non-revertive, a failed clock source is not selected again. If a node would enter
holdover due to the references being in previous failed state, then the node will select one of
the previously failed references rather than going into holdover.
