ref-order
Syntax
ref-order first second [third]
no ref-order
Context
config>system>sync-if-timing
Description
The synchronous equipment timing subsystem can lock to three 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 the 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
will no longer be qualified as a valid reference.
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.
second — Specifies the second timing reference to use in the reference order sequence.
third — Specifies the third timing reference to use in the reference order sequence.
