Clock Ssmcontrol - H3C S9500 Series Command Manual

Command Manual – Clock Monitoring
H3C S9500 Series Routing Switches
Description
Use the clock ssm command to set the SSM levels of the reference sources.
Use the undo clock ssm command to restore the default.
By default, the SSM level of all reference sources is unknown.
Note that:
For the line clock source, the SSM level configured is that of the clock source.
For Bits clock source, if the input signal is a 2048 kbps (E1) signal and the clock
forcessm off source is executed, the clock source adopts the SSM level derived
from the input signals and the SSM configured is omitted.
For Bits clock source, if the input signal is a 2048 kHz signal or a 2048 kbps signal
and the clock forcesssm on source command is executed, the clock source
adopts the SSM level configured.
After you set the SSM levels of the reference sources, it takes a period of time for
device response. In this case, you can check whether your configuration takes
effect through the display clock ssm-level command and the logging
information.
