Converting the device mode (QFX3500 and QFX3600 devices) —Enables you to
convert a QFX3500 or QFX3600 device into a Node device so it can be deployed within
a QFabric system. By default, QFX3500 and QFX3600 devices operate in
standalone
mode. Before the devices can participate within a QFabric system environment, you
must change the device mode for the switch to
node-device mode. To convert a
QFX3500 or QFX3600 device from standalone mode to Node device mode, connect
to the console port of the device, issue the
request chassis device-mode node-device
command, verify the future device mode with the show chassis device-mode command,
connect the management port of the device to the QFabric system control plane, and
reboot the device.
NOTE:
• Before you convert the device mode, you must upgrade the software on
your standalone device to a QFabric system Node and Interconnect
device software package that matches the QFabric system complete
software package used by your QFabric system. For example, if the
complete software package for your QFabric system is named
jinstall-qfabric-11.3X30.6.rpm
, you need to install the
jinstall-qfx-11.3X30.6-domestic-signed.tgz
package on your standalone
device. Matching the two software packages ensures a smooth and
successful addition of the device to the QFabric system inventory.
• Converting the device mode erases the switch configuration. We
recommend that you save your configuration to an external server or
USB flash drive before executing the device mode conversion commands
and rebooting the switch.

QFabric system control plane Ethernet network (EX4200 switches to support the
QFabric system)
—Provides a separate control plane network within the QFabric system
to handle management traffic. This design enables the data plane network to focus
on efficient, low-latency delivery of data, voice, and video traffic.
•
The QFX3000-G QFabric system control plane uses two sets of four EX4200 switches
each, configured as a pair of Virtual Chassis to connect all components within the
QFabric system. The dual Virtual Chassis architecture provides redundancy and high
availability to ensure reliable QFabric system operation for the Director group, the
Interconnect devices, and the Node devices.
•
The QFX3000-M QFabric system control plane uses two EX4200 switches to connect
all components within the QFabric system. The two EX4200 switches provide
redundancy and high availability to ensure reliable QFabric system operation for the
Director group, the Interconnect devices, and the Node devices.
Because the level of detail necessary to fully understand the control plane connections,
cabling, topology, and configuration is beyond the scope of this topic, see:

Plane” on page 283
