    Connecting QFX3100 Director Devices to EX8208 Switches for the QFabric System Control Plane

    A QFX3000 QFabric system control plane and management network is formed by connecting the QFX series devices in your network to two EX8208 switches. QFX3100 Director devices have two network modules configured with four 1000BASE-T or SFP ports. Use the network module ports to connect the QFX3100 Director group to each EX8208 switch (see Figure 1).

    Specific ports have been reserved on the EX8208 switch 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 control plane network configuration (see Example: Configuring the QFX3000-G QFabric System Control Plane with EX8208 Switches).

    Before you begin to connect a QFX3100 Director device to the control plane network:

    To connect each QFX3100 Director device to the control plane network (see Figure 1):

    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 the network modules on the first Director device to the EX8208 switches.
