Interconnecting Two Virtual Chassis for QFabric System Control Plane Redundancy
A QFX3000 QFabric system control plane and management network is formed by
connecting the QFX series devices in your network to two Virtual Chassis composed of
four EX4200 switches each. For redundancy and communication, you must connect the
two Virtual Chassis using the 10-Gigabit Ethernet uplink module ports configured as a
link aggregation group (LAG) (see Figure 80 on page 271).
