Connecting QFX3100 Director Devices to a Copper-Based QFX3000-G QFabric System Control Plane Network

 

A QFX3000-G 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 or four EX4300 switches. If you are creating a copper-based control plane 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 Figure 1).

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 0 through 3.

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

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:

To connect a QFX3100 Director device to the QFX3000-G QFabric control plane network (see Figure 1):

  1. Connect both network modules on the first Director device (labeled DG0 in Figure 1) to the two Virtual Chassis (labeled VC0 and VC1 in Figure 1). You connect the first three ports (labeled 0 through 2) on the first network module to the first Virtual Chassis (VC0. You connect the first three ports on the second network module (also labeled 0 through 2) to the second Virtual Chassis (VC0VC1). The ports used are the same on each Virtual Chassis.

    Network Module Port 3

    Virtual Chassis port ge-0/0/40

    Virtual Chassis port ge-1/0/40

    Virtual Chassis port ge-2/0/40

    Connect this port to the identical port on the other Director device. See Connecting QFX3100 Director Devices in a Director Group .

  2. Connect both network modules on the second Director device (labeled DG1 in Figure 1) to the two Virtual Chassis (labeled VC0 and VC1 in Figure 1). You connect the first three ports on the first network module to the first Virtual Chassis (VC0). You connect the first three ports on the second network module to the second Virtual Chassis (VC1). The ports used are the same on each Virtual Chassis.
