Juniper ACX2000 Configuration Guide

You can also enable ESMC on all interfaces with the interfaces all statement at the
preceding hierarchy level.
Setting the synchronization source quality level
Specify the expected quality of the incoming clock on this source. Specific quality-level
options are valid depending on the configured network-option; option-1 or option-2. Both
option-1 and option-2 SSM quality levels are supported. To set the synchronization source
quality level, use the following command:
set chassis synchronization source (bits | gps | interfaces interface-name)
quality-level (prc | prs |sec | smc | ssu-a | ssu-b | st2 | st3 | st3e | st4 |
stu | tnc)
The following output shows the configuration of the quality-level statement configured
with the prc option:
[edit]
user@host# show chassis
synchronization {
source {
bits {
quality-level prc;
}
}
}
Setting the synchronization source priority
Specify a priority level between 1 and 5. When not specified, gps has a higher priority than
bits,and bits has a higher default priority than other Gigabit Ethernet or 10 Gigabit Ethernet
clock sources, which have the lowest priority. To set the synchronization source priority,
use the following command:
set chassis synchronization source (bits | gps | interfaces interface-name)
priority number
The following output shows the configuration of the priority statement:
[edit]
user@host# show chassis
synchronization {
source {
bits {
priority 2;
}
}
}
Setting the synchronization source wait to restore time
A wait-to-restore time can be configured for each port. When a port’s signal transitions
out of the signal fail state, it must be fault free for the wait-to-restore time before it is
again considered by the selection process. The range is from 0 through 12 minutes. The
default time is 5 minutes.
To set the synchronization source wait-to-restore time, use the following command:
