Connecting QFX3100 Director Devices to a Fiber-Based QFX3000-M QFabric System Control Plane Network

Before you begin to connect a QFX3100 Director device to the fiber-based QFX3000-M QFabric system control plane network:

A QFX3000-M QFabric system control plane and management network is formed by connecting the QFX Series devices in your network to two EX4200 switches or to two EX4300 switches. QFX3100 Director devices have two 4-port network modules. Use the network module ports to connect the QFX3100 Director group to the EX Series switches (see Figure 1).

Use the following QFX3100 Director devices and EX Series switches for a fiber-based QFX3000-M QFabric system control plane network:

  • QFX3100 Director devices with SFP network modules installed. Each SFP network module provides four SFP ports labeled 0 through 3.

  • Either an EX4200-24F switch with an SFP+ uplink module installed or an EX4300-48P with an SFP+ uplink module installed.

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

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

Laser Warning:

Do not look directly into a fiber-optic transceiver or into the ends of fiber-optic cables. Fiber-optic transceivers and fiber-optic cables connected to transceivers emit laser light that can damage your eyes.

  1. Connect both network modules on the first Director device (labeled DG0 in Figure 1) to the two EX Series switches (labeled EX0 and EX1 in Figure 1). You connect the first two ports (labeled 0 and 1) on the first network module to the first EX Series switch (EX0). You connect the first two ports on the second network module (also labeled 0 and 1) to the second EX Series switch (EX1). The ports used are the same on each switch.

    EX Series switch port ge-0/0/21

    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 EX Series switches (labeled EX0 and EX1 in Figure 1). You connect the first two ports on the first network module to the first EX Series switch (EX0). You connect the first two ports on the second network module to the second EX Series switch (EX1). The ports used are the same on each switch.
