user@switch# set preprovisioned
8. Specify all the members that you want included in the Virtual Chassis, listing each
switch’s serial number with the desired member ID and role:
[edit virtual-chassis]
user@switch# set member 0 serial-number abc123 role routing-engine
user@switch# set member 1 serial-number def456 role routing-engine
user@switch# set member 2 serial-number ghi789 role line-card
user@switch# set member 3 serial-number jkl012 role line-card
9. (Optional. Recommended for a two-member Virtual Chassis) Disable the split and
merge feature:
[edit virtual-chassis]
user@switch# set no-split-detection
10. Power on the other member switches. The member IDs and roles have beendetermined
by the configuration, so you can power on the member switches in any order.
11. (Required if you are configuring a mixed Virtual Chassis) Set each individual switch
into mixed mode and reboot the switch to complete the configuration:
NOTE: You must complete this step if your Virtual Chassis includes a
combination of different types of switches, except when you are
configuring a Virtual Chassis that includes only QFX3500 and QFX3600
switches or only QFX5110 and QFX5100 switches (which are considered
to be non-mixed Virtual Chassis). See Understanding Mixed EX Series and
QFX Series Virtual Chassis or Virtual Chassis Fabric for details.

12. (Optional) On each individual member switch, configure the ports that will be used
to interconnect the member switches into VCPs using the following command:
NOTE: SFP+, QSFP+, and 10Gbps copper links are automatically
configured into VCPs when the preprovisioned configuration is set.
This step is, therefore, optional and should only be used when a VCP is
not automatically created.
user@switch> request virtual-chassis vc-port set pic-slot pic-slot-number port port-number
where pic-slot-number is the PIC slot number.
For instance, if you wanted to set port 0 on the QSFP+ interface on PIC slot 2 as a
VCP:
