Juniper QFX3000-G QFabric, Deployment Manual, Page: 304 / 652

You can configure some devices to act as a standalone switch or participate in a QFabric
system in a particular role. To change the role of your device, you must set the device
mode.
Table 76 on page 278 shows the device modes available for various devices.
Table 76: Support for device mode options
QFX3600 QFX3500 Device mode
• N/A Interconnect device
• • Node device
• • Standalone
To convert a device to a different mode, issue the
request chassis device-mode
command
and specify the desired device mode. You verify the current and future device mode with
the
show chassis device-mode command.
When you convert a device from standalone mode to either Node device or Interconnect
device mode, the software prepares the device to be configured automatically by the
QFabric system. However, changing the device mode erases all configuration data on
the device.
NOTE: The QFX3600 switch requires Jloader Release 1.1.8 before you can
convert the switch to Interconnect device mode. For more information, see:
Jloader 1.1.8 Release for QFX-Series Platforms .
CAUTION: We recommend that you back up your device configuration to an
external location before converting a device to a different device mode.
The following procedures illustrate the conversion options available when you modify a
device mode:
•
Convert from standalone switch mode to Node device mode
• Convert from Node device mode to Interconnect device mode
• Convert from Interconnect device mode to Node device mode
•
Convert from Node device mode or Interconnect device mode to standalone switch
mode
