QFX3100 Director Device Overview
The Juniper Networks QFX3100 Director device is used to manage the Juniper Networks
QFX3000-G QFabric system.
You connect Gigabit Ethernet ports on a QFX3100 Director device to Gigabit Ethernet
ports on two Virtual Chassis composed of Juniper Networks EX4200 Ethernet switches
to form the control plane and management network for the QFabric system. The Virtual
Chassis interconnects the Juniper Networks QFX3500 Node devices, Juniper Networks
QFX3008-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.
