Configuring the Number of Active Ports on vMX
You can specify the number of active ports for vMX. The default number of ports is 10, but you can specify any value in the range of 1 through 23. You can change this number if you want to limit the number of Ethernet interfaces in the VCP VM to match the number of NICs added to the VFP VM.
Note:
If you are running virtio interfaces in lite mode, you can use up to 96 ports.
Other configurations running in performance mode support up to 23 ports.
To specify the number of active ports, configure the number
of ports at the [edit chassis fpc 0 pic 0] hierarchy level.
