A Virtual Chassis must have one member designated as the master switch and one
member designated as the backup switch. All other switches in the configuration are
designated as being in the linecard role. You manage Virtual Chassis operation through
the master switch.
The number of switches that you can configure in each of the three types of Virtual
Chassis that are described in this topic and the role that can be assigned to each switch
in the Virtual Chassis depends on the Juniper Networks Junos operating system (Junos
OS) release that is running on the switches.
