Understanding EX Series Virtual Chassis Switch Version Compatibility

Note: This topic applies to all EX Series Virtual Chassis except EX8200 Virtual Chassis. See Understanding EX8200 Virtual Chassis Compatibility Requirements for information about EX8200 Virtual Chassis.

EX2200, EX3300, EX4200, EX4500, or EX4550 switches must be running the same software versions to be interconnected into a Virtual Chassis. 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, and any combination of EX4200, EX4500, or EX4550 switches can be connected together to form a mixed Virtual Chassis. 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 cannot join the Virtual Chassis configuration.
