Predefined user roles

network-admin

network-operator

Parameters

job job-id: Specifies a process by its ID. The value range for job-id is 1 to 2147483647. If you do not specify a process, this command displays the statistics for the entire system's CPU usage (the total CPU usage of all processes). To view the IDs and names of the running processes, use the display process command. For more information, see Network Management and Monitoring Command Reference.

Usage guidelines

After CPU usage tracking is enabled, the system regularly samples CPU usage and saves the samples to a buffer. This command displays the most recent 60 samples in a coordinate system as follows:

· The vertical axis represents the CPU usage. If a statistic is not a multiple of the usage step, it is rounded up or down to the closest multiple of the usage step. For example, if the CPU usage step is 5%, the statistic 53% is rounded up to 55%, and the statistic 52% is rounded down to 50%.

· The horizontal axis represents the time.

· Pound signs (#) indicate the CPU usage. The value on the vertical axis for the topmost pound sign at a specific time represents the CPU usage at that time.

Examples

# Display the historical CPU usage statistics.

Views

System view

Predefined user roles

network-admin

Parameters

interval: Specifies the port status detection timer value in seconds. The value range is 0 to 300. The vlaue of 0 inidcates that port status detection is not automatically performed, and you need to execute the undo shutdown command to restore the port status manually.

Usage guidelines

The device starts a port status detection timer when a port is shut down by a protocol. If the port has been in down state before the timer expires, the device will set the port status to the port's physical status.

If you change the timer setting during port detection, the device compares the new setting (T1) with the time that elapsed since the port was shut down (T).

If T < T1, the port will be brought up after T1 – T seconds.

If T ≥ T1, the port is brought up immediately.

For example, the timer setting is 30 seconds. If you change it to 10 seconds 2 seconds after the port is shut down, the port will come up 8 seconds later. If you change the timer setting to 2 seconds 10 seconds after the port is shut down, the port comes up immediately.

Parameters

lane-number: Specifies a lane by its number. The value is in the range of 1 to 4 for a 200G transceiver module and in the range of 1 to 8 for a 400G transceiver module. If you do not specify a lane, this command applies to all lanes of the transceiver module.

host-checker: Specifies the host-side signal check mode.

host-generator: Specifies the host-side signal generation mode.

media-checker: Specifies the media-side signal check mode.

media-generator: Specifies the medial-side signal generation mode.

prbs-pattern: Specifies a signal transmission PRBS pattern. The value range varies by transceiver module model.

Usage guidelines

This command is available only for 200G and 400G transceiver modules that support CMIS 4.0.

This command settings will be saved in a register of the transceiver module. If the transceiver module has a power loss, the command settings will be cleared. You must re-execute the command after a power recovery.

Examples

# Specify the host-side signal generation mode and signal transmission pattern of PRBS-31Q for all lanes of the transceiver module in FourHundredGigE1/1/1.

<Sysname> system-view

[Sysname] interface fourhundredgige 1/1/1

[Sysname-FourHundredGigE1/1/1] transceiver lane pattern host-generator PRBS-31Q

This operation causes the service to be down for a while. Continue? [Y/N]:Y

transceiver power-mode

Use transceiver power-mode to set a power mode for a 400-GE transceiver module.

Use undo transceiver power-mode to restore the default.

NOTE:

This command is supported only on the S9820-8M switch.

Syntax

transceiver power-mode { high | low }

undo transceiver power-mode

Default

The default varies by transceiver module model.

Usage guidelines

A transceiver module generally operates in high power mode. If the transceiver module does not work for a long time, you can switch the transceiver module to low power mode to reduce power consumption. In low power mode, the transceiver module does not transmit signals.

The power mode setting is saved in a register on the transceiver module. It is not saved to the configuration file.

Examples

# Set the 400-GE transceiver module in interface FourHundredGigE 1/1/1 to high power mode.

<Sysname> system-view

[Sysname] interface fourhundredgige 1/1/1

[Sysname-FourHundredGigE1/1/1] transceiver power-mode high

# Set the 400-GE transceiver module in interface FourHundredGigE 1/1/1 to low power mode.

<Sysname> system-view

[Sysname] interface fourhundredgige 1/1/1

[Sysname-FourHundredGigE1/1/1] transceiver power-mode low

This command will place the transceiver module in low-power-consumption mode, disabling the transceiver module from transmitting data. Continue? [Y/N]:Y
