Understanding EX3300 Virtual Chassis Hardware Configuration
Virtual Chassis is a feature in Juniper Networks EX3300 Ethernet Switches that allows
you to interconnect two or more EX3300 switches, enabling them to operate as a unified,
single, high bandwidth switch. You can interconnect a maximum of six EX3300 switches
by using the uplink ports configured as Virtual Chassis ports (VCPs) to form a Virtual
Chassis. By default, uplink ports 2 and 3 are configured as VCPs.
NOTE: EX3300 switches do not have dedicated VCPs.
All EX3300 switch models support Virtual Chassis, and you can interconnect different
models, which allows you to choose among a range of possible port configurations within
the same Virtual Chassis.
The Virtual Chassis configuration includes a master switch and a backup switch, with all
other switches in the configuration designated as “linecard” member 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.
