Understanding EX8200 Virtual Chassis Compatibility Requirements
For Juniper Networks EX8200 Ethernet Switches to be interconnected into a Virtual Chassis, the switches and the XRE200 External Routing Engines must be running the same software versions. The master external Routing Engine 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). A switch that is running a different version of software will not be allowed to join the Virtual Chassis configuration.
After an EX8200 Virtual Chassis is connected, software upgrades for all switches and external Routing Engines in the Virtual Chassis can be performed simultaneously. This process ensures all devices are running the same version of Junos OS. See Understanding Software Upgrades in an EX8200 Virtual Chassis.
Different models in the EX8200 line of switches can be members of the same Virtual Chassis; for instance, an XRE200 External Routing Engine can be used to connect a Virtual Chassis composed of one EX8208 switch and one EX8216 switch.
