display cpu-usage
Format
display cpu-usage [ slave | slot slot-id ] [ vcpu vcpu-index ]
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 S5720-HI, S5730-HI, S5731-H, S5731-S, S5731S-H, S5731S-S, S5732-H, S6720-HI, S6730-H, S6730S-H, S6730-S, and S6730S-S support the vcpu vcpu-index 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 a slot ID. |
The value depends on the device configuration. |
vcpu vcpu-index |
Displays the usage of a specified virtual CPU. |
Specify the vcpu-index parameter based on the hardware configuration. |
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.
