Connecting a QFX3500 Node Device to a Copper-Based 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 EX4200 or EX4300 switches. If you are creating a copper-based control plane network, you use four EX Series Ethernet switches in each Virtual Chassis. QFX3500 Node devices have an RJ-45 or SFP management board. Use the RJ-45 management ports (labeled C0 and C1) to connect the QFX3500 Node device to each Virtual Chassis (see Figure 1).

Use the following QFX3500 Node devices and EX4200 or EX4300 switches for a copper-based QFX3000-M QFabric system control plane network:

  • QFX3500 Node devices with an RJ-45 management board installed. The RJ-45 management board provides two RJ-45 1-Gbps management ports labeled C0 and C1.

  • Virtual Chassis EX4200-48T or EX4300-48T switch members with an SFP+ uplink module installed.

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

To connect a QFX3500 Node device to the QFX3000-G 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 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.
