Chapter 1 Clock Monitoring Configuration
Commands
Note:
The clock monitoring configuration commands are available when the SRPUs are
installed with a clock module. If the SRPUs are not installed with a clock module, all
these commands are invisible. For information about SRPUs installed with a clock
module, refer to the S9500 Series Routing Switches Installation Manual.
1.1 Clock Monitoring Configuration Commands
1.1.1 clock
Syntax
clock { auto | manual source source-number }
undo clock work-mode
View
System view
Default Level
2: System level
Parameters
auto: Sets the clock monitoring module to work in auto mode.
manual source source-number: Sets the clock monitoring module to work in manual
mode. source-number indicates the primary clock source number in manual mode.
Description
Use the clock command to set the work mode of the SRPU clock monitoring module,
that is, the mode the clock monitoring module uses to choose clock source, either auto
mode or manual mode.
Use the undo clock work-mode command to restore the default.
By default, the work mode is auto.

Command Manual – Clock Monitoring
H3C S9500 Series Routing Switches Chapter 1 Clock Monitoring Configuration Commands
1-2
Note that:
zBefore configuring the work mode as manual, you should use the display clock
source command to view the clock source state. Only clock sources working
normally can be successfully configured as the primary clock source.
zAfter you set the work mode of the clock monitoring module, it takes a period of
time for device response. In this case, you can check whether your configuration
takes effect through the display clock device command and the logging
information.
Examples
# Set the working mode of the SRPU clock monitoring module to manual, and the
primary clock source to 1.
<Sysname> system-view
[Sysname] clock manual source 1
1.1.2 clock forcessm
Syntax
clock forcessm { on | off } source source-number
View
System view
Default Level
2: System level
Parameters
on: Specifiesnot to derive the SSM levels from the clock source, namely, uses the SSM
levels manually configured by users.
off: Derives the SSM levels from the clock source. The user-configured SSM levels are
not effective.
source-number: Number of clock source.
Description
Use the clock forcessm command to set whether to derive the SSM levels from clock
source or to configure the SSM levels manually by users.
By default, the SSM levels are manually configured.
Related commands: clock ssm.
Examples
# Derive SSM level from the clock source 1.

2: System level
Parameters
interface-type interface-number: Specifies a port by its type and number.
Description
Use the clock lpuport command to specify the input port of the line clock source (LPU
port).
Use the undo clock lpuport command to restore the default.
By default, the LPU port is the first configurable port by port name in lexical order of the
ports on the interface card.
Note:
zFor a WAN interface card, if you set the port clock to work in slave mode, you must
use this command to select the LPU port of the clock source of the interface card.
zThe clock mode of the LPU port of the line clock source must be slave.
Examples
# Set the LPU port of the line clock source as interface POS 3/1/1.

H3C S9500 Series Routing Switches Chapter 1 Clock Monitoring Configuration Commands
1-6
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:
zFor the line clock source, the SSM level configured is that of the clock source.
zFor 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.
zFor 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.
zAfter 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.
Examples
# Set the SSM level of clock source 1 to DNU.

reference source automatic selection.
zWhen SSM level is not activated, you can still set and view the SSM levels, but
they are ignored in reference source automatic selection are decided by reference
source priority.
