display memory-usage
Format
display memory-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 memory usage of a slave switch in a stack. This parameter is valid only when multiple switches form a stack. |
- |
| slot slot-id | Displays memory usage of a slot ID. |
The value depends on the device configuration. |
| vcpu vcpu-index | Specifies the virtual CPU number. |
Specify the vcpu-index parameter based on the hardware configuration. |
Usage Guidelines
Memory usage is an important index to evaluate device performance. A high memory usage will cause service faults. You can use the display memory-usage command to view memory usage to check whether devices are working properly.
The memory usage displayed using the display memory-usage command is based on the total available memory of a process.
