revert
Syntax [no] revert
Context config>system>sync-if-timing
Supported
Platforms
Supported on all 7210 SAS platforms as described in this document, including platforms
configured in the access-uplink operating mode; not supported on 7210 SAS platforms
configured in the standalone-VC operating mode
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

Description This command configures the source port for timing reference ref1 or ref2. If the port is

reference order configured using the ref-order command.
The no form of this command deletes the source port from the reference.
Parameters port-id — Specifies the physical port.
