Chapter 36: Cabling a Fiber-Based Control Plane for the QFX3000-G QFabric System
Specific ports have been reserved on the Virtual Chassis to connect to the Interconnect
devices, Node devices, and QFX3100 Director devices in your QFabric system. Such design
simplifies installation and facilitates timely deployment of a QFabric system. It also
enables the use of a standard Virtual Chassis configuration (see Example: Configuring a
Fiber-Based Control Plane for the QFX3000-G QFabric System).
Before you begin to connect a QFX3008-I Interconnect Device to the fiber-based
QFX3000-G QFabric system control plane network:
Install your QFabric system hardware (Director group, Interconnect devices, and Node
devices). For more information, see
Device" on page 377, "Installing and Connecting a QFX3008-I Interconnect Device" on
page 389, "Installing and Connecting a QFX3600 or QFX3600-I Device" on page
"Installing and Connecting a QFX3500 Device" on page
Install your Virtual Chassis hardware. For more information, see

Switch" on page 492.
Create two Virtual Chassis of eight EX4200-24F switch members or four EX4300-48P
switch members.
See "Cabling EX4200 or EX4300 Series Switches Virtual Chassis for a QFX3000-G
QFabric System Control Plane" on page
See Configuring an EX4200, EX4500, or EX4550 Virtual Chassis (CLI Procedure) or
Configuring an EX2300, EX3400, or EX4300 Virtual Chassis.
Interconnect the two Virtual Chassis switches using the 10-Gigabit Ethernet SFP+
uplink ports. For more information, see
Fiber-Based QFX3000-G QFabric System Control Plane Redundancy" on page
Ensure that 1-Gigabit Ethernet SFP transceivers are installed in port
both Control Boards for each QFX3008-I Interconnect device (see
Transceiver in a QFX Series Device" on page
and required cables, see
Ensure that you have installed 1-Gigabit Ethernet SFP transceivers in the ports you are
using on each EX Series switch (see Installing a Transceiver). For a list of supported
transceivers, see
The Hardware Compatibility Tool
Ensure that you have appropriate fiber-optic cables.
Ensure that you have taken the necessary precautions for safe handling of lasers (see
"Laser and LED Safety Guidelines and Warnings for the QFX Series" on page

Chassis port mappings. Specific ports have been reserved on the Virtual Chassis to
connect to each of the QFX Series device types. Such design simplifies installation and
facilitates timely deployment of a QFabric system.
