Chassis LAG Connections
Before you begin to interconnect two Virtual Chassis for QFX3000-G QFabric system
control plane redundancy:
Install your QFabric system hardware (Director group, Interconnect devices, and Node
devices). See "Installing and Connecting a QFX3100 Director Device" on page
"Installing and Connecting a QFX3008-I Interconnect Device" on page 389 "Installing
and Connecting a QFX3600 or QFX3600-I Device" on page
Connecting a QFX3500 Device" on page
Install your EX4200 or EX4300 switches. See
Switch" on page 491 or "Installing and Connecting an EX4300 Switch" on page
Create two Virtual Chassis of four members each.
See "Cabling EX4200 or EX4300 Series Switches Virtual Chassis for a QFX3000-G
QFabric System Control Plane" on page
See Configuring an EX4200, EX4500, or EX4550 Virtual Chassis (CLI Procedure) or
Configuring an EX2300, EX3400, or EX4300 Virtual Chassis.
Ensure that you have installed a 10-Gigabit Ethernet SFP+ transceivers in ports
on each Virtual Chassis member uplink module (see Installing a Transceiver). EX4200

uplink modules only support SFP+ transceivers installed in ports
uplink modules support SFP+ transceivers installed in all uplink module ports. For a
list of supported transceivers, see Pluggable Transceivers Supported on EX4200 Switches
and Pluggable Transceivers Supported on EX4300 Switches.
Instead of using optical transceivers, you can use 10-Gigabit Ethernet SFP+ direct-attach
(DAC) cables. For a list of supported DAC cables, see SFP+ Direct Attach Copper Cables
for EX Series Switches. The procedure below assumes you are using optical transceivers,
but the port mappings in
Ensure that you have appropriate fiber-optic cables (see Pluggable Transceivers
Supported on EX4200 Switches or Pluggable Transceivers Supported on EX4300
Switches).
Ensure that you have taken the necessary precautions for safe handling of lasers (see
Laser and LED Safety Guidelines and Warnings).
Use Table 141 on page 499
Chassis-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.
