SWA-0 is going to be configured in the example to function as the master of the Virtual
Chassis configuration. Thus, the properties that you specify for SWA-0 will apply to
the entire Virtual Chassis configuration, including all the member switches that you
specify in the preprovisioned configuration file.

In this example, five EX4200 switches (SWA-0 through SWA-4) are interconnected with
their dedicated VCPs in wiring closet A and five EX4200 switches (SWA-5 through
SWA-9) are interconnected with their dedicated VCPs in wiring closet B.
SWA-0 (in wiring closet A) is going to be the master of the Virtual Chassis configuration.
This example shows how to create a preprovisioned configuration file on SWA-0 for all
member switches that will be interconnected in the Virtual Chassis configuration. The
preprovisioned configuration file includes member IDs for the members in wiring closet
A and for the members in wiring closet B.
SWA-5 (in wiring closet B) is going to be the backup of the Virtual Chassis configuration.
Both SWA-0 and SWA-5 are specified in the preprovisioned configuration file with the
role of . All other members are specified with the role of
