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

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).
  • The command output does not support split-screen display.
  • 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.

If the standby switch in an S12700 cluster has no MPUs, this command cannot display the electronic label of the standby switch.

NOTE:

The electronic label version of devices delivered since V200R011 has been updated to version 4.0. This version adds the following fields compared to earlier versions:

  • Model indicates the hardware external model of the device.
  • ExInfo indicates the hardware extension information of the device. This field is not provided in electronic labels of optical modules.
  • ElabelVersion indicates the version of the elabel.

Example

# Display the electronic label in chassis 1.
