The Juniper Networks QFX3100 Director device is used to manage the Juniper Networks
QFX3000-G and QFX3000-M QFabric systems.
You connect Gigabit Ethernet ports on a QFX3100 Director device to Gigabit Ethernet
ports on Juniper Networks EX4200 Ethernet switches to form the control plane and
management network for the QFabric system. The EX4200 switches interconnect the
Juniper Networks QFX3500, QFX3600, and QFX5100 Node devices, Juniper Networks
QFX3008-I or QFX3600-I Interconnect devices, and QFX3100 Director devices.
A QFabric system requires two QFX3100 Director devices interconnected as a QFX3100
Director group. The second QFX3100 Director device provides redundancy for the control
plane and management network.
