Syntax
- vm vm-id
- vm vm-id fp [1..2] dist-cpu-protection
- vm vm-id fp [1..2] ingress mode {access | network} queue-group ref-point-name instance instance statistics
- vm vm-id soft [hard-reset-unsupported-mdas]
Context
- [Tree] clear vm
Description
This command re-initializes the statistics for the specified VM.
Parameters
- vm-id
- Specifies the VM ID for which information is to be cleared.
- soft
- Keyword to issue a soft-reset of the I/O module.
- {access | network}
- access | network
- ref-point-name
- Specifies the reference point name, up to 32 characters.
- instance
- Specifies the instance.
- statistics
- Keyword to clear statistics only.

vm
Syntax
- vm
- vm vm-id [detail]
- vm vm-id memory-pools
- vm vm-id cpu [sample-period seconds]
- vm vm-id ht-pairs
- vm vm-id virtual fp
Context
- [Tree] show vm
Description
This command displays information for the specified VM.
In the output screens, the number of cores for the selected VM CPU is also included. The CPU Time and CPU Usage is displayed per CP Core in the VM CPU output example.
In the VM virtual FP output, the Utilization percentage is displayed per fast path Core.
Parameters
- vm-id
- Specifies the ID of the VM for which information is to be displayed.
- detail
- Keyword to display more information for the specified VM.
- memory-pools
- Keyword to display memory pool details for the specified VM.
- cpu
- Keyword to display CPU usage details for the specified VM.
- seconds
- Specifies the sampling period in seconds.
- virtual fp
- Displays the virtual FP statistics for the specified VM.Note:
- The Utilization value shows the current utilization of the specific core by this vFP task on the specified VM. It is the ratio of the useful versus the sum of the useful and busy-loop executions of a vFP task, all of which run in a busy-loop mode for performance reasons.
- When hyper-threading is enabled, some performance-critical tasks (for example, NIC and Scheduler) run only on one core of the hyper-thread pair, with the sibling core being idle (not used for any tasks).
- ht-pairs
- Displays hyper-threading vCPU pairs for the specified VM.Note:
- When the reported HT state in the output is ON, hyper-threading optimization is enabled on the VM.
- When the HT state is N/A, either hyper-threading is not supported by the CPU or hyper-threading optimization support is not available on the VM.
- When the HT state is OFF, hyper-threading optimization is disabled.
Output
The following output examples show virtual fabric information.
