You can also enable ESMC on all interfaces with the
preceding hierarchy level.
Specify the expected quality of the incoming clock on this source. Specific quality-level
options are valid depending on the configured
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
with the option:
prc
[edit]
user@host# show chassis
synchronization {
source {
bits {
quality-level prc;
}
}
}
Specify a priority level between 1 and 5. When not specified,
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
[edit]
user@host# show chassis
synchronization {
source {
bits {
priority 2;
}
}
}
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
default time is 5 minutes.
To set the synchronization source wait-to-restore time, use the following command:
