The synchronous equipment timing subsystem can lock to different timing reference inputs, those specified in the ref1, ref2, and ptp command configuration. This command organizes the priority order of the timing references.
If a reference source is disabled, then the clock from the next reference source as defined by ref-order is used. If all reference sources are disabled, then clocking is derived from a local oscillator.
If a sync-if-timing reference is linked to a source port that is operationally down, the port is no longer qualified as a valid reference. Depending on the platform used, either SFP or Fixed copper ports can be used as a reference.
The no form of this command reverts the reference order to the default values.
On the 7210 SAS-D ETR, ref1 must be configured to use one of ports 1/1/1 to 1/1/4 and ref2 must be configured to use either port 1/1/5 or 1/1/6. The software enforces this check. Ports 1/1/7 to 1/1/10 can be configured as either ref1 or ref2.

Specifies the first timing reference to use in the reference order sequence.
Specifies the second timing reference to use in the reference order sequence.
Specifies the third timing reference to use in the reference order sequence. This parameter is only supported on 7210 SAS-K devices.
Specifies that PTP must be used as a timing reference. PTP is not supported on 7210 SAS-Dxp.

This command enables 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 is used. If a reference with a higher priority becomes valid, a reference switch over to that reference is 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 is initiated. When the failed reference becomes operational, it is eligible for selection.

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 this command deletes the source port from the reference.
Specifies the physical port.
