NOTE: See "Installing Software on an EX Series Switch with a Single
Routing Engine (CLI Procedure)" on page 84 or "Installing Software on an
EX8200 Switch with Redundant Routing Engines (CLI Procedure)" on
page 85 to upgrade software on EX8200 switches.
An EX8200 Virtual Chassis extends two EX8200 switches into a single virtual device,
thereby simplifying network management, configuration, and troubleshooting.
In this example, two EX8200 switches are connected to an XRE200 External Routing
Engine to form an EX8200 Virtual Chassis. A backup XRE200 External Routing Engine
is also part of the topology and has connections to the master external Routing Engine
and both member switches. A Virtual Chassis port (VCP) link is also configured to connect
the switches, thereby forming a full meshed topology that utilizes all possible VCP links
within the Virtual Chassis topology.
This example shows an EX8200 Virtual Chassis composed of four devices: a master
XRE200 External Routing Engine, a backup XRE200 External Routing engine, an EX8208
member switch, and an EX8216 member switch.
Table 165 on page 1088 explains the components of the example EX8200 Virtual Chassis
topology.
