OS for EX Series Ethernet Switches, Release 10.4
You can deterministically control both the role and the member ID assigned to each
member switch in an EX4200 Virtual Chassis configuration by creating a preprovisioned
configuration file.
A preprovisioned configuration file links the serial number of each EX4200 switch in the
configuration to a specified member ID and role. The serial number must be specified in
the configuration file for the member to be recognized as part of the Virtual Chassis
configuration.
You must select two members that you want to make eligible for election as master of
the Virtual Chassis configuration. When you list these two members in the preprovisioned
configuration file, you designate both members as
the master of the Virtual Chassis configuration and the other will function as the backup.
You designate additional members, which are not eligible for election as master, has
having the role in the preprovisioned configuration file.

NOTE: When you use a preprovisioned configuration, you cannot modify the
mastership priority or member ID of member switches through the user
interfaces.
NOTE: After you have created a preprovisioned Virtual Chassis configuration,
you can use the autoprovisioning feature to add member switches to that
configuration. See "Adding a New Switch to an Existing EX4200 Virtual
Chassis (CLI Procedure)" on page 986.
