Release Information

Statement introduced in Junos OS Release 15.1F4 and 16.1R1 for vMX routers.

Description

(vMX routers only) Enables vMX to run in lite mode and disables performance mode. Lite mode needs fewer vCPUs and memory to run at lower bandwidth. If you are using paravirtualized network interfaces such as virtio (for KVM) or VMXNET3 (for VMware) for lab simulation use cases, you can enable lite mode.

Note

Make sure you have configured the proper number of vCPUs and memory for your VMs based on your use case. If you have not configured enough vCPUs for performance mode, vMX runs in lite mode.

Starting with Junos OS Release 15.1F6, performance mode is enabled by default for vMX.

Note

The FPC reboots if you change this configuration.

Options

lite-modeEnables lite mode.

To disable lite mode, enable performance mode by including the performance-mode statement at the [edit chassis fpc 0] hierarchy level.
