Usage Guidelines

Generally, device versions have matching NMS software. The NMS software needs to apply to all the devices supported by matching versions. Otherwise, the NMS cannot manage devices. If the NMS version is an earlier version but the current device is running a later version that does not match the current NMS version, the NMS cannot manage the current device.

To decouple the NMS version and device version, a compatible device model developed based on an earlier version is defined for each device model. If the NMS cannot manage a device because of version mismatch, obtain information about the device compatible with the current device. The NMS can then use the obtained information to manage the current device.

For example:

S5700LI_R7 is a device model newly available in V200R007. The NMS software version that matches the device software version is V200R007.

S5700LI_R5 is a device model newly available in V200R005. The NMS software version that matches the device software version is V200R005.

When you use the NMS of V200R005 to manage S5700LI_R7, the device cannot be managed because of version mismatch. The NMS then obtains compatibility information about S5700LI_R7 and learns that it is compatible with S5700LI_R5. Subsequently, the NMS uses information about S5700LI_R5 to manage the current device.

If the device does not have a compatible version, the system will display a message, indicating that no compatible information exists after the display compatible-information command is executed.

Compatible information of stacked devices can also be displayed.

Example

# Display compatible information of a device.

Item

Description

Compatible SysOids

System OID of an old device version.

Compatible Version

Old device version compatible with the current device version.

ProductName

Product name of a new device.

display cpu-usage

Function

The display cpu-usage command displays CPU usage statistics.

Format

display cpu-usage [ slave | slot slot-id ] [ vcpu vcpu ]

NOTE:

The slave parameter is not supported if the switch does not support the stacking function or does not have the stacking function enabled.

Only the S5720HI supports the vcpu vcpu parameter.

Parameters

Parameter Description Value
slave

Displays the CPU usage of slave devices in a stack. This parameter is valid only in a stack system.

-

slot slot-id
  • Specifies the slot ID if stacking is not configured.
  • Specifies the stack ID if stacking is configured.

The value is 0 if stacking is not configured. The value range depends on the stack configuration if stacking is configured.

vcpu vcpu

Displays the usage of a specified virtual CPU.

Specify the vcpu parameter based on the hardware configuration.

Default Level

1: Monitoring level

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.

display cpu-usage configuration

Function

The display cpu-usage configuration command displays CPU usage configuration.

Format

display cpu-usage configuration [ slave | slot slot-id ]

NOTE:

The slave parameter is not supported if the switch does not support the stacking function or does not have the stacking function enabled.

Parameters

Parameter Description Value
slave

Displays CPU usage configuration of standby switches in a stack. This parameter is valid only when multiple switches form stack.

-

slot slot-id

Displays device CPU usage configuration. slot-id specifies the stack ID.

The value is 0 if stacking is not configured. The value ranges from 0 to 8 if stacking is configured.

Views

All views

Default Level

1: Monitoring level

Usage Guidelines

This command displays the alarm threshold and recovery threshold.

  • When CPU usage reaches the alarm threshold, the system generates a CPU usage alarm.

  • When CPU usage falls within the recovery threshold, the system generates a clear alarm.

Example

# Display CPU usage configuration .

<HUAWEI> display cpu-usage configuration
The CPU usage monitor is turned on. 
The current monitor cycle is 60 seconds.
The current monitor warning threshold is 95%.
The current monitor restore threshold is 80%. 
Table 3-3  Description of the display cpu-usage configuration command output

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

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.
