Connecting a QFX3008-I Interconnect 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 QFabric system devices in your network to two Virtual Chassis composed of four EX4200 switches or four EX4300 each. QFX3008-I Interconnect Devices have four small form factor pluggable plus (SFP+) management ports on each Control Board. Use the SFP+ management ports to connect the QFX3008-I Interconnect Devices to each Virtual Chassis (see Figure 1.

Specific ports have been reserved on the Virtual Chassis 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. It also enables the use of a standard Virtual Chassis configuration (see Example: Configuring the Virtual Chassis for a Copper-Based QFX3000-G QFabric System Control Plane).

Before you begin to connect a QFX3008-I Interconnect Device to the copper-based QFX3000-G QFabric system control plane network:

To connect each QFX3008-I Interconnect Device to the QFX3000-G QFabric system control plane network (see Figure 1:

  1. Connect the first Interconnect device.
