Connecting a QFX5100-24Q Interconnect Device to a Copper-Based QFX3000-M QFabric System Control Plane Network

Before you begin to connect a QFX5100-24Q Interconnect device to the copper-based QFX3000-M QFabric system control plane and management 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, Installing and Connecting a QFX3500 Device, and QFX5100 Standalone Installation Overview.

    Note:

    There can be a maximum of four Interconnect devices in the QFX3000-M QFabric system.

  • 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 ports. See Interconnecting Two EX Series Switches for QFX3000-M QFabric System Control Plane Redundancy.

    Note:

    Use either EX4200-24T switches with an SFP+ uplink module installed or use an EX4300-48T with an SFP+ uplink module installed.

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

  • Use Table 1 to determine the QFX5100-24Q Interconnect 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 Interconnect device below are not preassigned to the Interconnect devices that are shipped to you. They represent the order in which you connect the Node devices. For example, the first Interconnect device (IC0) is connected to port 16 (ge-0/0/16) 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. QFX5100-24Q Interconnect devices have two management ports (labeled C0 and C1), to connect the QFX5100-24Q Interconnect device to each EX Series switch (see Figure 1).

Note:

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

Specific ports have been reserved on the EX Series switch to connect to the Interconnect devices, Node devices, and QFX3100 Director devices in your QFabric system. Such design simplifies installation and facilitates timely deployment of a QFabric system.

To connect each QFX5100-24Q Interconnect device to the copper-based control plane network:

  1. Connect the first QFX5100-24Q Interconnect device.
    1. Connect one end of the first RJ-45 patch cable to the management port labeled C0.
      Note:

      Some product SKUs have two ports labeled C0. The second C0 port is for fiber connections.

    2. Connect the other end of that cable to port ge-0/0/16 on the first EX Series switch.
    3. Connect one end of the second RJ-45 patch cable to the management port labeled C1.
    4. Connect the other end of that cable to port ge-0/0/16 on the second EX Series switch.
  2. Connect the second QFX5100-24Q Interconnect device.
    1. Connect one end of the first RJ-45 patch cable to the management port labeled C0.
    2. Connect the other end of that cable to port ge-0/0/17 on the first EX Series switch.
    3. Connect one end of the second RJ-45 patch cable to the management port labeled C1.
    4. Connect the other end of that cable to port ge-0/0/17 on the second EX Series switch.
  3. Connect the third QFX5100-24Q Interconnect device if used.
    1. Connect one end of the first RJ-45 patch cable to the management port labeled C0.
    2. Connect the other end of that cable to port ge-0/0/18 on the first EX Series switch.
    3. Connect one end of the second RJ-45 patch cable to the management port labeled C1.
    4. Connect the other end of that cable to port ge-0/0/18 on the second EX Series switch.
  4. Connect the fourth QFX5100-24Q Interconnect device if used.
    1. Connect one end of the first RJ-45 patch cable to the management port labeled C0.
    2. Connect the other end of that cable to port ge-0/0/19 on the first EX Series switch.
    3. Connect one end of the second RJ-45 patch cable to the management port labeled C1.
    4. Connect the other end of that cable to port ge-0/0/19 on the second EX Series switch.
