revert
Syntax [no] revert
Context config>system>sync-if-timing
Description This command allows the clock to revert to a higher priority reference if the current reference goes
offline or becomes unstable.
If revertive switching is enabled, the highest-priority valid timing reference will be used. If a
reference with a higher priority becomes valid, a reference switch over to that reference will be
initiated. If a failure on the current reference occurs, the next highest reference takes over.
If non- revertive switching is enabled, the valid active reference always remains selected, even if a
higher-priority reference becomes available. If this reference becomes invalid, a reference switch
over to a valid reference with the highest priority will be initiated. When the failed reference becomes
operational, it is eligible for selection.
Default no revert
source-port
Syntax source-port port-id
no source-port
Context config>system>sync-if-timing>ref1
config>system>sync-if-timing>ref2
Description This command configures the source port for timing reference ref1 or ref2. If the port is unavailable
or the link is down, then the reference sources are re-evaluated according to the reference order
configured in the ref-order command.
The no form of the command deletes the source port from the reference.
Parameters port-id — Identify the physical port in the slot/mda/port format.
