Understanding EX Series Virtual Chassis Components

Maximum Number of Switches per Virtual Chassis

16
For instance, if you have two 10-Gigabit SFP+ interfaces configured as VCPs between
member switches, a LAG with two member links with 20 Gbps of total bandwidth is
formed.
An EX9200 Virtual Chassis can be composed of any two EX9200 switches. Both EX9200
switches must have dual Routing Engines installed, and all Routing Engines must be
running the same version of Junos OS. All combinations of EX9204, EX9208, and EX9214
switches can be interconnected to form a Virtual Chassis.
