Syntax
minimum-quality;
Hierarchy Level
[edit chassis synchronization output interfaces external] [edit chassis synchronization output interfaces (external-0/0 | external-1/0)] [edit chassis synchronization]
Hierarchy level [edit chassis synchronization] added
for ACX710 in Junos OS Release 20.2R1.
Description
Configure the minimum quality level threshold to select a clock source (see Table 1). If the quality level of the output clock source drops below the configured minimum quality level threshold, the external output clock is suppressed on the external output interface—external—on SCBE and on the external output interfaces—external-0/0 and external-1/0—on SCBE2.
