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
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
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:
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 QFX3008-I Interconnect Device, Installing and Connecting a QFX3600 or QFX3600-I Device, and Installing and Connecting a QFX3500 Device.
Create two Virtual Chassis of four members each.
Interconnect the two Virtual Chassis switches using the 10-Gigabit Ethernet SFP+ uplink ports. For more information, see Interconnecting Two Virtual Chassis for Copper-Based QFX3000-G QFabric System Control Plane Redundancy.
Ensure that you have two RJ-45 patch cables available. 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-Virtual Chassis port mappings. Specific ports have been reserved on the Virtual Chassis to connect to each of the QFabric system device types. Such design simplifies installation and facilitates timely deployment of a QFabric system. It also permits the use of a standard Virtual Chassis configuration (see Example: Configuring the Virtual Chassis for a Copper-Based QFX3000-G QFabric System Control Plane).
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 port (Node 0) is connected to port
ge-0/0/0on each Virtual Chassis.
Table 1: QFX3500 Node Device-to-Virtual Chassis Copper-Based Control Plane Port Assignments
To connect a QFX3500 Node device to the QFX3000-G QFabric system control plane network (see Figure 1):
- Connect one end of the first RJ-45 patch cable to the
first management port (labeled
C0) on the Node device management board.
- Connect the other end of that cable to the appropriate member and port on the Virtual Chassis. See Table 1.
- Connect one end of the second RJ-45 patch cable to the
second management port (labeled
C1) on the Node device management board.
- 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-0/0/0on the first Virtual Chassis, you connect the second cable to
ge-0/0/0on the second Virtual Chassis.
- Repeat this procedure for each Node device.
