1.1 Clock Module Commands
1.1.1 clock
Syntax
clock { auto | manual source source-no }
undo clock work-mode
View
System view
Parameters
auto: The clock works in the auto mode.
manual: The clock works in the manual mode.
source: Sets the primary clock source in manual mode.
source-no: Index of clock source, ranging from 1 to 18.
Description
Use the clock command to set the work mode of the clock module on the main processing card (SRPU), namely, the mode of clock selecting clock source, including auto mode and manual mode.
Use the undo clock work-mode command to restore the work mode of clock module on the SRPU to the default value. By default, the work mode of the clock module on the SRPU is auto mode.
If it is necessary to set the clock source, you need to query the state of the clock source first. Only the clock source working normally can be selected.
1) In the manual mode, the clock module does not switch the clock source actively; it only traces the specified primary clock source. The set clock source priority and SSM level are not involved in control. If the primary clock source is lost, the phase lock state of the clock module switches into Hold.
2) In auto mode
l If SSM is not involved in control, the set SSM level will be neglected, and the clock module will select a clock source by priority. If two clock sources have the same priority, they will be selected in the high-to-low order from clock source 1 to clock source 18. If the available clock source with the highest priority is lost, the next available clock source with the highest priority will be selected automatically. When the original clock source recovers, the clock module will switch to the original clock source. In this case, the manually set primary clock source will not work.
l If SSM is engaged in control, the clock module will select a clock source by SSM level first. If two clock sources have the same SSM level, they will be selected by the priority. If they have the same priority, they will be selected in high-to-low order from clock source 1 to clock source 18. If the available clock source with highest SSM level is lost, it will be switched to the next available clock source with the highest SSM level automatically. When the original clock source recovers, the clock module will switch back to the original clock source. In this case, the manually set primary clock source will not work.
3) Clock sources not engaged in switching
The following clock sources are neglected during clock source selection (when SSM is engaged in control):
l Clock sources whose signal is lost are unavailable clock sources, and are not engaged in switching.
l Clock sources with the priority of 0xFF are unconfigured clock sources, and are not engaged in switching.
l Clock sources with the SSM level being DNU should not be used for synchronization, and are not engaged in switching.

1.1.3 clock lpuport
Syntax
clock lpuport { port-type port-number | port-name }
View
System view
Parameters
port-type: Type of port.
port-number: Number of port.
port-name: Name of port.
Description
Use the clock lpuport command to select the input port of the line clock source of the interface card.
& Note:
For the WAN card, when the clock mode of the selected port is slave, this command selects the clocks input by the interface card to the clock pitch board on the SRPU. The clock pinch board selects the most precise clock signal as the clock source of the card for sending services. Therefore, for the WAN card, when the clock mode is the slave mode, use this command to select the port of the card for taking the clock source.
Examples
# Set the output port of the line clock source of the POS interface card 3 to port 1.
<H3C> system-view
System View: return to User View with Ctrl+Z.

1.1.5 clock sa-bit
Syntax
clock sa-bit { sa4 | sa5 | sa6 | sa7 | sa8 } source source-no
undo clock sa-bit source source-no
View
System view
Parameters
source-no: Number of the Bits clock source, ranging from 1 to 2.
sa4: Time slot of sa4 bit.
sa5: Time slot of sa5 bit.
sa6: Time slot of sa6 bit.
sa7: Time slot of sa7 bit.

1.1.6 clock ssm
Syntax
clock ssm { dnu | lnc | prc | sets | tnc | unknown } source source-no
undo clock ssm source source-no
View
System view
Parameters
dnu: Should be used for synchronization (DNU).
lnc: G.812 local node clock signal (LNC).
prc:G.811 clock signal (PRC).
sets: Clock source signal of SDH equipment (SETS).
tnc: G.812 transfer node clock signal (TNC).
unknown: The quality of synchronization is unknown.
source-no: Number of clock source, ranging from 1 to 18.
Description
Use the clock ssm command to set the SSM level of each clock source.
Use the undo clock ssm command to restore the SSM level of each clock source to the default value. By default, the SSM level of each clock source is unknown (the quality of synchronization is unknown).
Note that:
l For line clock source, the set SSM level is the SSM level of the clock source.
l For Bits clock source, if the input signal is 2048 kbps (E1) and SSM is engaged in control, the SSM level of the clock source is the SSM level extracted from the input signal, and the set SSM level is neglected.
l For Bits clock source, if the input signal is 2048kHz signal, or the input signal is 2048kbits/s signal but SSM is not engaged in control, the set SSM level is the SSM level of the clock source.
SSM means Synchronization Status Marker, which is also referred to as synchronous quality information. It is used to indicate the level of synchronous timing signal in synchronous timing transfer link. For line clock sources, SSM level is extracted by the interface card and reported to the SRPU, and then the SRPU sets the SSM level of the line clock source for the clock module.
When the clock module is powered on, the default SSM level of all clock sources is unknown (the quality of synchronization is unknown). From high to low, the order of SSM levels is: PRC > TNC > LNC > SETS > unknown > DNU. If the SSM level of a clock source is DNU and SSM is engaged in control, the clock source will not be selected during clock source switching.
The SRPU will notify the corresponding interface card about the SSM level after setting the SSM level. If the SSM level of the line clock source can be extracted, the set SSM level will be invalidated. Otherwise, the set SSM level will apply.
Examples
# Set the SSM level of clock source 1 to DNU.
<H3C> system-view
System View: return to User View with Ctrl+Z.
[H3C] clock ssm dnu source 1
# Restore the SSM level of clock source 1 to the default configuration.
<H3C> system-view
System View: return to User View with Ctrl+Z.

Syntax
clock ssmcontrol { on | off }
undo clock ssmcontrol
View
System view
Parameters
on: Enable SSM to be engaged in control.
off: Disable SSM from being engaged in control.
Description
Use the clock ssmcontrol command to set whether the SSM function of the clock module is engaged in control.
Use the undo clock ssm control command to restore the SSM function of the clock module to the default configuration.
Note the following two conditions:
l SSM is engaged in control: The level of the clock source is first determined by its SSM level during automatic clock source switching.
