Connecting a QFX5100 Node Device to a Copper-Based QFX3000-G QFabric System Control Plane Network

Before you begin to connect a QFX5100 Node device to the 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 the four EX Series Ethernet switches in each Virtual Chassis. QFX5100-48S Node devices have an RJ-45 C0 located under the CON port, and an SFP cage C1 that can be used as a copper management port. Use the RJ-45 management port (labeled C0 and the SFP management port C1) to connect the QFX5100 Node device to each Virtual Chassis. See Figure 1 for a cabling example.

Use the following QFX5100 Node devices and EX4200 switches for a copper-based QFX3000-M QFabric system control plane network:

  • QFX5100 Node devices with:

    • em0–RJ-45 (1000BASE-T) management Ethernet port (C0)

    • em1–SFP management Ethernet port (C1) cage (socket for 1 GbE copper SFP)

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

To connect a QFX5100 Node device to the QFX3000-G QFabric system control plane network):

  1. Connect one end of the first RJ-45 patch cable to the management port (labeled C0) on the Node device management board.
  2. Connect the other end of that cable to the appropriate member and port on the Virtual Chassis. 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 member and port on the second Virtual Chassis. This should be the same member number and 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 Virtual Chassis, you connect the second cable to ge-0/0/0 on the second Virtual Chassis.
  5. Repeat this procedure for each Node device.
