The following output shows the configuration of the switchover-mode statement with
the non-revertive option:
[edit]
user@host# show chassis
synchronization {
switchover-mode non-revertive;
}
Setting the clock source
The configured clock source is the candidate for selection by the clock selection algorithm.
The clock source can be the router’s BITS T1 or E1 interface, GPS, or an interface with an
upstream clock source. To set the clock source, use the following command:
set chassis synchronization source (bits | gps | interfaces interface-name)
The following output shows the configuration of the source statement with the bits option
and the mandatory network-option statement. When bits is configured with option-1 on
the ACX2000 router, the Synchronous Ethernet equipment is optimized for 2048 Kbps,
the speed of an E1 interface.
[edit]
user@host# show chassis
synchronization {
network-option option-1;
source {
bits;
}
}
NOTE: For the source statement configuration to take effect, you must set
the network-option (option-1 | option-2) statement at the [edit chassis
synchronization] hierarchy level.
The bits option is not supported on the ACX1000 router.
Setting ESMC transmit interface
The ESMC transmit interface is the interface on which ESMC transmit messages are
permitted. To enable ESMC packet transmit, use the following command:
set chassis synchronization esmc-transmit interfaces interface-name
The following output shows the configuration of the esmc-transmit statement:
[edit]
user@host# show chassis
synchronization {
esmc-transmit {
interfaces ge-0/1/0;
}
}
