Understanding Virtual Chassis Hardware Configuration on an EX4200 Switch
Virtual Chassis is a feature in Juniper Networks EX4200 Ethernet Switches that allows
you to interconnect two or more EX4200 switches, enabling them to operate as a unified
single high bandwidth switch. You can interconnect a maximum of 10 EX4200 switches
through the dedicated 64-Gbps Virtual Chassis ports (VCPs) or the uplink module ports
configured as VCPs to form a Virtual Chassis. All EX4200 switch models support Virtual
Chassis, and you can interconnect different models, offering a range of port configurations,
within the same Virtual Chassis.
The Virtual Chassis configuration includes designation of a master switch and a backup
switch, with all other switches in the configuration designated as "line card" role switches.
Virtual Chassis operation is managed through the master switch. Each switch in the
Virtual Chassis is assigned a unique identifier that is displayed on the switch LCD.
