An EX8200 Virtual Chassis is multiple Juniper Networks EX8200 Ethernet Switches
connected together that operate as a single network entity. The advantages of connecting
multiple EX8200 switches into a Virtual Chassis include better-managed bandwidth at
a network layer, simplified configuration and maintenance because multiple devices can
be managed as a single device, and a simplified Layer 2 network topology that minimizes
or eliminates the need for loop prevention protocols such as Spanning Tree Protocol
(STP).
The XRE200 Routing Engine is the device that connects all member switches into a single
Virtual Chassis. An EX8200 Virtual Chassis is formed by connecting a Virtual Chassis
port (VCP) on an XRE200 External Routing Engine to the management ports (labeled
