Syntax ref-order first second [third]
no ref-order
Context config>system>sync-if-timing
Description The synchronous equipment timing subsystem can lock to different timing reference inputs, those
specified in the ref1 and ref2 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.
Note that 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. Only SFP based Ethernet ports can be used for reference in
the current release.
The no form of the command resets the reference order to the default values.
Default ref1 ref2
Parameters first — Specifies the first timing reference to use in the reference order sequence.
Values ref1, ref2
second — Specifies the second timing reference to use in the reference order sequence.
