Connecting a QFX3500 Node Device to a Copper-Based QFX3000-M QFabric System Control Plane Network

Before you begin to connect a QFX3500 Node device to the copper-based QFX3000-M QFabric system control plane network:

  • Install your QFabric system hardware (Director group, Interconnect devices, and Node devices). For more information, see Installing and Connecting a QFX3100 Director Device, Installing and Connecting a QFX3600 or QFX3600-I Device, and Installing and Connecting a QFX3500 Device.

  • Install your EX4200 or EX4300 switches. See Installing and Connecting an EX4200 Switch or Installing and Connecting an EX4300 Switch.

  • Interconnect the two EX Series switches using the SFP+ uplink module. See Interconnecting Two EX Series Switches for QFX3000-M QFabric System Control Plane Redundancy.

  • Ensure that you have two RJ-45 patch cables available for each Node device. For cable specifications, see Cable Specifications for Copper-Based Control Plane Connections for the QFabric System.

  • Use Table 1 to determine the QFX3500 Node device-to-EX Series switch port mappings. Specific ports have been reserved on the EX Series switch to connect to each of the QFX Series device types. Such design simplifies installation and facilitates timely deployment of a QFabric system.

    Note:

    The numerical identifiers for each Node device below are not preassigned to the Node devices that are shipped to you. They represent the order in which you connect the Node devices. For example, the first Node device (Node0) is connected to port 0 (ge-0/0/0) on the first EX Series switch EX0 and the second EX Series switch EX1.

A QFX3000-M QFabric system control plane and management network is formed by connecting the QFX Series devices in your network to two EX4200 or two EX4300 switches. QFX3500 Node devices have two management ports labeled C0 and C1. Use the management ports to connect the QFX3500 Node device to each EX Series switch (see Figure 1).

Note:

You may not mix EX4200 and EX4300 switches in the same QFabric system.

CAUTION:

For redundancy, each QFX3500 Node device must be connected to two EX Series switches.

Use the following QFX3500 Node devices and EX Series switches switches for a copper-based QFX3000-M QFabric system control plane network:

  • QFX3500 Node devices with a 1000BASE-T management board installed. The 1000BASE-T management board provides two 1000BASE-T management ports (labeled C0 and C1) with RJ-45 connectors.

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

To connect a QFX3500 Node device to the copper-based QFX3000-M QFabric system control plane network (see Figure 1):

  1. Connect one end of the first RJ-45 patch cable to the first management port (labeled C0) on the Node device management board.
  2. Connect the other end of that cable to the appropriate port on the EX Series switch. See Table 1.
  3. Connect one end of the second RJ-45 patch cable to the second management port (labeled C1) on the Node device management board.
  4. Connect the other end of that cable to the appropriate port on the second EX Series switch. This should be the same port number that you connected to in Step 2. For example, if you connected the first cable to ge-0/0/0 on the first EX Series switch, you connect the second cable to ge-0/0/0 on the second EX Series switch.
  5. Repeat this procedure for each QFX3500 Node device.
