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.

Note that:

l           Before 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.

l           After 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: Specifies not 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.

<Sysname> system-view

[Sysname] clock forcessm off source 1

1.1.3  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 (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.

 

 

Examples

# Set the LPU port of the line clock source as interface POS 3/1/1.

<Sysname> system-view

[Sysname] clock lpuport pos 3/1/1

1.1.4  clock priority

Syntax

undo clock priority source source-number

View

System view

Default Level

2: System level

Parameters

value: Priority value.

source-number: Number of clock source.

Description

Use the clock priority command to the reference source priority.

Use the undo clock priority command to the 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

1.1.5  clock sa-bit

Syntax

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

sa8: Indicates that the bit position is sa8.

source-number: Number of Bits clock source.

Description

Use the clock sa-bit command to set the bit position 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 position used to transmit the SSM information of Bits clock source 1 to sa5.

<Sysname> system-view

[Sysname] clock sa-bit sa5 source 1

1.1.6  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 to DNU. (DoNotUse).

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

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

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

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

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

source-number: Number of reference source.

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:

l           For the line clock source, the SSM level configured is that of the clock source.

l           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.

l           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.

l           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

1.1.7  clock ssmcontrol

Syntax

undo clock ssmcontrol

View

System view

Default Level

2: System level

Parameters

on: Activates SSM level.

off: Deactivates 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.

Note that:

l           When SSM level is activated, the SSM level becomes the decisive factor in reference source automatic selection.

l           When 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.

Examples

# Activate SSM of clock monitoring module.
