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, where source-number represents the primary clock source number in manual mode, in the range of 1 to 14.

Description

Use the clock command to set the work mode of the clock monitoring module, either auto mode or manual mode.

Use the undo clock work-mode command to restore the default.

By default, the work mode is auto.

Before configuring the work mode to manual, use the display clock source command to view the clock source state. Only clocks that work normally can be configured as the primary clock source.

After you set the work mode of the clock monitoring module, it takes a period of time for device response. You can check whether your configuration takes effect through the display clock device command and the logging information.

Examples

# Set the clock work mode to manual, and the primary clock source to 1.

<Sysname> system-view

[Sysname] clock manual source 1

clock forcessm

Syntax

clock forcessm { on | off } source source-number

View

System view

Default level

2: System level

Parameters

on: Specifies not to derive the SSM levels from the clock source, which means to use the SSM levels manually configured by users.

off: Specifies to derive the SSM levels from the clock source, which means the user-configured SSM levels do not take effect.

source source-number: Number of clock source, in the range of 1 to 2.

Description

Use the clock forcessm command to set how the SSM levels are derived.

By default, no SSM level is derived from any clock source, which means the SSM levels are manually configured.

Related commands: clock ssm.

Examples

# Derive SSM level from the clock source 1.

<Sysname> system-view

[Sysname] clock forcessm off source 1

clock lpuport

Syntax

clock lpuport interface-type interface-number

undo clock lpuport interface-type interface-number

View

System view

Default level

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.

Use the undo clock lpuport command to restore the default.

By default, the clock input port is the first configurable port by port name in lexical order of the interface card.

 

NOTE: ·       For a POS interface card, if you set the port clock to work in slave mode, you must use this command to select the input port of the board clock source. ·       The clock of the input port of the line clock source must work in slave mode. For how to set the clock mode by using the clock command, see Interface Command Reference.

 

Examples

# Set the input port of the line clock source to POS interface 3/1/1.

<Sysname> system-view

[Sysname] clock lpuport pos 3/1/1

clock priority

Syntax

undo clock priority source source-number

View

System view

Default level

2: System level

Parameters

value: Priority value, which is in the range of 1 to 14  or takes the value of 255.

source source-number: Number of clock source, in the range of 1 to 14.

Description

Use the clock priority command to set the reference source priority.

Use the undo clock priority command to restore the default.

By default, the priority of all reference sources is 255.

Examples

# Set the priority of reference source 2 to 3.

<Sysname> system-view

[Sysname] clock priority 3 source 2

clock sa-bit

Syntax

clock sa-bit { sa4 | sa5 | sa6 | sa7 | sa8 } source source-number

undo clock sa-bit source source-number

View

System view

Default level

2: System level

Parameters

sa4: Indicates that the bit position is sa4.

sa5: Indicates that the bit position is sa5.

sa6: Indicates that the bit position is sa6.

sa7: Indicates that the bit position is sa7.

sa8: Indicates that the bit position is sa8.

source source-number: Number of Bits clock source, in the range of 1 to 2.

Description

Use the clock sa-bit command to set the bit used to transmit Bits clock source information.

Use the undo clock sa-bit command to restore the default.

By default, sa4 is used to carry the SSM information.

Examples

# Set the bit used to transmit Bits clock source 1 information to sa5.

<Sysname> system-view

[Sysname] clock sa-bit sa5 source 1

clock ssm

Syntax

clock ssm { dnu | lnc | prc | sets | tnc | unknown } source source-number

undo clock ssm source source-number

View

System view

Default level

2: System level

Parameters

dnu: Specifies the SSM level as DNU. (DoNotUse).

lnc: Specifies the SSM level as LNC (G.812 local node clock signal).

prc: Specifies the SSM level as PRC (G.811 clock signal).

sets: Specifies the SSM level as SETS (SDH device clock source signal).

tnc: Specifies the SSM level as TNC (G.812 transit node clock signal).

unknown: Specifies the SSM level as unknown (Unknown synchronization quality).

source source-number: Number of reference source, in the range of 1 to 14.

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.

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.

Examples

# Set the SSM level of clock source 1 to DNU.

<Sysname> system-view

[Sysname] clock ssm dnu source 1

clock ssmcontrol

Syntax

clock ssmcontrol { on | off }

undo clock ssmcontrol

View

System view

Default level

2: System level

Parameters

on: Specifies to activate SSM level.

off: Specifies to deactivate SSM level.

Description

Use the clock ssmcontrol command to activate or deactivate SSM level.

Use the undo clock ssmcontrol command to restore the default.

By default, SSM level is deactivated.

When SSM level is activated, the clock source is determined by the SSM level in reference source automatic selection.

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

Examples

# Activate SSM of clock monitoring module.

<Sysname> system-view

[Sysname] clock ssmcontrol on
