Usage Guidelines

CPU usage is an important indicator to evaluate device performance. A high CPU usage will cause service faults, for example, BGP route flapping, frequent VRRP active/standby switchover, and even failed device login. You can use the display cpu-usage command to view CPU usage to check whether devices are working properly.

When the CPU usage is high, rectify the fault according to "Troubleshooting: High CPU" in Huawei S Series Campus Switches Troubleshooting Guide.

This command displays information about the CPU usage on the MPU or the specified interface board. If the slave or slot slot-id is not specified, the CPU usage of the master MPU is displayed.

Example

# Display the CPU usage on the master MPU.

Usage Guidelines

Usage Scenario

The system collects CPU usage statistics at a specified interval (usually 60s) and saves them in the historical record table. To check CPU usage statistics within a period, run the display cpu-usage history command, and the command output helps you determine whether the CPU is working properly.

In the display cpu-usage history command output, the x-coordinate indicates the specified period, and the y-coordinate indicates the CPU usage.

Precautions

If CPU usage is constantly higher than the upper alarm threshold (95% by default) before the feature is deployed on a large scale, check the device to troubleshoot the fault.

Usage Guidelines

If you need to check whether a switch is working properly, run the display device command to view hardware information of the components and board registration status on the switch.

In V200R001C00 and later versions, the display device and display elabel commands may display different names for a board. The reason is that V200R001C00 regulates the board names in the display device command, but electronic labels of boards do not change after the software upgrade.

Example

Usage Guidelines

Usage Scenario

When a fault occurs in the system, you can use the display diagnostic-information command to collect diagnostic information for fault location.

The display diagnostic-information command output includes the output for multiple display commands, such as display clock, display version, and display current-configuration. Running the display diagnostic-information command is like running these display commands in batches.

Precautions

  • If the file-name parameter is not specified, diagnostic information is only displayed on the screen. If the file-name parameter is specified, diagnostic information is only stored to a specified file but not displayed on the screen, and the command level is management level (3).
  • If this command displays a long output, press Ctrl+C to abort this command.

  • This command displays diagnostic information, which helps locate faults but may affect system performance. For example, CPU usage may become high. Therefore, do not use this command when the system is running properly.

  • Running the display diagnostic-information command simultaneously on multiple terminals connected to the device is prohibited. This is because CPU usage of the device may obviously increase and the device performance may be degraded.

  • When you run this command, the device obtains or uses some personal data of users, such as the STA MAC address. Delete the personal data immediately after the command is executed to ensure user data security.

Usage Guidelines

Electronic labels identify hardware components. You can use the display elabel command to view the electronic label information.

No electronic label is displayed for an electrical interface or a combo interface working as an electrical interface.

NOTE:

For a new device delivered since V200R011, its electronic label version has been updated to version 4.0, which has the following changes compared to earlier versions:

  • The Model field is added to indicate the hardware external model of the device.
  • The ExInfo field is added to indicate the hardware extension information of the device. This field does not exist in electronic labels of optical modules.
  • The ElabelVersion is added to indicate the version of the elabel.

Usage Guidelines

You can run this command to view general information, manufacture information, and alarm information about an optical module. If you specify the verbose keyword, diagnostic information is also displayed in addition to the preceding information.

If the LPU specified in the command does not support optical modules, the system displays a message indicating that the port does not support this command.

Among 40GE optical modules, the QSFP-40G-iSR4, QSFP-40G-eSR4, CFP-40G-LR4, CFP-40G-ER4, and CFP-40G-ZR4 model do not support optical power measurement.

When S9700 switches use EH1D2VS08000 CSS cards to set up a CSS system, you can use the display transceiver slot slot-id [ verbose ] command to view information about optical modules on the CSS cards.

Some parameters including the current and optical power will be displayed for each lane of the 40GE interfaces (including 40GE interfaces split from 100GE interfaces) and 100GE interfaces.
