Display KHI Performance Information
Use the following commands to display KHI information about the performance of the switch.
Procedure
- Display memory performance
and utilization statistics on the specified slot or all slots:
show khi performance memory [history | {slot[-slot][,...]}]
Note
Depending on the hardware platform, you can display virtual memory history.
