Connecting QFX3100 Director Devices to a Copper-Based QFX3000-M QFabric System Control Plane Network

Before you begin to connect a QFX3100 Director device to the copper-based QFX3000-M QFabric system control plane network:

Install your QFabric system hardware (Director group, Interconnect devices, and Node devices). See Installing and Connecting a QFX3100 Director Device, Installing and Connecting a QFX3600 or QFX3600-I Device, and Installing and Connecting a QFX3500 Device.
Install your EX4200 or EX4300 switches. See Installing and Connecting an EX4200 Switch or Installing and Connecting an EX4300 Switch.

Note:
Use either EX4200-24T switches with an SFP+ uplink module installed or use an EX4300-48T with an SFP+ uplink module installed.
Install transceivers in ports 0 and 1 of the uplink module (see Install a Transceiver).
- For an EX4200 Switch control plane, ensure that you have installed 1-Gigabit Ethernet SFP transceivers in each EX4200 switch uplink module. For a list of supported transceivers, see Pluggable Transceivers Supported on EX4200 Switches.
- For an EX4300 Switch control plane, ensure that you have installed 10-Gigabit Ethernet SFP+ transceivers in each EX4300 switch uplink module. For a list of supported transceivers, see Pluggable Transceivers Supported on EX4300 Switches.
Interconnect the two EX Series switches. See Interconnecting Two EX Series Switches for QFX3000-M QFabric System Control Plane Redundancy.
Connect the two QFX3100 Director devices to create a Director group. See Connecting QFX3100 Director Devices in a Director Group.
Ensure that you have four RJ-45 patch cables available for each Director device. For cable specifications, see Cable Specifications for Copper-Based Control Plane Connections for the QFabric System.

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. QFX3100 Director devices have two 4-port network modules. Use the network module ports to connect the QFX3100 Director group to the EX Series switches (see Figure 1).

Use the following QFX3100 Director devices and EX Series switches for a copper-based QFX3000-M QFabric system control plane network:

QFX3100 Director devices with 1000BASE-T network modules installed. Each 1000BASE-T network module provides four 1000BASE-T ports (labeled 0 through 3) with RJ-45 connectors.
EX4200-24T or EX4300-48T switches with an SFP+ uplink module installed.

Specific ports have been reserved on the EX Series switches to connect to each of the QFX Series device types. Such design simplifies installation and facilitates timely deployment of a QFabric system.

To connect a QFX3100 Director device to the copper-based QFX3000-M QFabric control plane network (see Figure 1):

Connect both network modules on the first Director device (labeled DG0 in Figure 1) to the two EX4200 or EX4300 switches (labeled EX0 and EX1 in Figure 1). You connect the first two ports (labeled 0 and 1) on the first network module to the first EX Series switch (EX0). You connect the first two ports on the second network module (also labeled 0 and 1) to the second EX Series switch (EX1). The ports used are the same on each EX Series switch.

Table 1: QFX3100 Director Device-to-EX Series Switch Control Plane Port Assignments for DG0
Network Module Port 0	Network Module Port 1	Network Module Port 3
EX Series switch port ge-0/0/20	EX Series switch port ge-0/0/21	Connect this port to the identical port on the other Director device. See Connecting QFX3100 Director Devices in a Director Group.

Connect both network modules on the second Director device (labeled DG1 in Figure 1) to the two EX4200 or EX4300 switches (labeled EX0 and EX1 in Figure 1). You connect the first two ports on the first network module to the first EX Series switch (EX0). You connect the first two ports on the second network module to the second EX Series switch (EX1). The ports used are the same on each EX Series switch.

Network Module Port 0	Network Module Port 1	Network Module Port 3
EX Series switch port ge-0/0/22	EX Series switch port ge-0/0/23	Connect this port to the identical port on the other Director device. See Connecting QFX3100 Director Devices in a Director Group.
