show vmhost mode
Syntax
show vmhost mode show vmhost mode mode-name
Description
The show vmhost mode command displays the CPU and memory
allocations for various components in the current mode of the
device. The show vmhost mode
mode-name command displays the
CPU and memory allocations for various components for a specific
mode of the device.
Note:
Starting in Junos OS Release 22.1R1, the output of the
show vmhost mode command displays
the maximum memory that can be configured and the currently
configured memory for VNFs. In addition, the CPU allocations
are displayed as a number range (for example, 4-7) instead
of individual numbers (for example, 4,5,6,7).
