Chapter 37: EX4200 Virtual Chassis—Overview, Components, and Configurations
NOTE: If an EX4200 switch is interconnected with other switches in a Virtual
Chassis configuration, each individual switch that is included as a member
of the configuration is identified with a member ID. The member ID functions
as an FPC slot number. When you are configuring interfaces for a Virtual
Chassis configuration, you specify the appropriate member ID (0 through 9)
as the slot element of the interface name.
The default factory settings for a Virtual Chassis configuration include FPC
0 as a member of the default VLAN because FPC 0 is configured as part of
the
ethernet-switching
default VLAN, add the
those interfaces.

For Juniper Networks EX4200 Ethernet Switches to be interconnected to form an EX4200
Virtual Chassis, the switches must be running the same software versions. The master
checks the hardware version, the Juniper Networks Junos operating system (Junos OS)
version, and other component versions running in a switch that is physically interconnected
to its Virtual Chassis port (VCP). Different hardware models can be members of the same
Virtual Chassis configuration. However, the master will not assign a member ID to a switch
that is running a different software version. A switch that is running a different version of
software will not be allowed to join the Virtual Chassis configuration.
