Usage Guidelines
T he network-clock revertive command specifies whether or not the clock source is revertive. Clock
sources with the same priority are always non-revertive. The default value is non-revertive.
In non-revertive switching, a switch to an alternate reference is maintained even after the original
reference recovers from the failure that caused the switch. In revertive switching, the clock switches back
to the original reference after that reference recovers from the failure, independent of the condition of
the alternate reference.
Examples
This example shows how to make the clock-source revertive:
Router(config)#[no] network-clock revertive
