CONFIGURATION GUIDE RELEASE 22.9.R1
System management
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.

Description
This command configures the source port for timing reference ref1 or ref2. If the port is unavailable or the
link is down, the reference sources are reevaluated according to the reference order configured using the
ref-order command.
The no form of this command deletes the source port from the reference.
Parameters

Specifies the physical port.
