Description
slot

source relative to other synchronization
sources configured in the unit.

unknown
The quality level applied to the selected
synchronization source. This enables the
system to select the source with the
highest quality as the current
synchronization source.
If the quality is set to automatic, then
the quality is determined by the
received SSMs. If no valid SSM messages
are received or in case of interface
failure (such as LOS, LOC, LOF), the
quality becomes "failure."
SSM must be enabled on the remote
interface in order for the interface to
receive SSM messages.
If the quality is configured to a fixed
value, then the quality status becomes
“failure” upon interface failure (such as
LOS, LOC, LOF).
The following command configures Ethernet port 2 as a synchronization source with priority = 8, and quality =
automatic:
root> platform sync source add eth-interface slot 1 port 2 priority 8
quality automatic
The following command changes the priority of this synchronization source to 6:
root> platform sync source edit eth-interface slot 1 port 2 priority 6
The following command removes this synchronization source:
root> platform sync source remove eth-interface slot 1 port 2

To configure a radio interface as a synchronization source, enter the following command in root view:
