network, you use four EX4200-48T or four EX4300-48T Ethernet switches in each Virtual

Chassis. QFX3100 Director devices have two RJ-45 or SFP network modules. Use the

RJ-45 network module ports to connect the QFX3100 Director group to each Virtual

Chassis (see

QFabric System

Use the following QFX3100 Director devices and EX Series switches for a copper-based

QFX3000-G QFabric system control plane network:

QFX3100 Director devices with RJ-45 network modules installed. Each RJ-45 network

module provides four RJ-45 ports labeled

Virtual Chassis EX4200-48T or EX4300-48T switches with an SFP+ uplink module

Specific ports have been reserved on the Virtual Chassis to connect to each of the QFabric

system device types. Such design simplifies installation and facilitates timely deployment

of a QFabric system. It also permits the use of a standard Virtual Chassis configuration

(see Example: Configuring the Virtual Chassis for a Copper-Based QFX3000-G QFabric

System Control Plane).

Before you begin to connect a QFX3100 Director device to the copper-based QFX3000-G

control plane network:

Install your QFabric system hardware (Director group, Interconnect devices, and Node

devices). See
