devices in the VCF. See Installing Software Packages on QFX Series Devices or Installing Software on an EX
Series Switch with a Virtual Chassis or Single Routing Engine (CLI Procedure). Then follow the applicable
procedure to add the device based on how your VCF is configured.
CAUTION: QFX5100 switches running a Junos OS image that includes “-qfx-5-” in
the software package filename must be upgraded to a package filename that includes
“-qfx-5e-” before being added to a QFX5110 Virtual Chassis or VCF. See Upgrading a
QFX5100 Switch with a USB Device to Join a QFX5110 Virtual Chassis or Virtual Chassis
Fabric.

Adding a Leaf Device to an Autoprovisioned Virtual Chassis Fabric
To add a leaf device to an autoprovisioned VCF:
1. Log onto the device that you are adding to the VCF.
2. (Optional) Perform this step if you want to avoid the downtime associated with an extra reboot when
your device is interconnected into your VCF. If you do not perform this step, the VCF auto-detects the
fabric and mixed mode settings and, if needed, reboots the device as part of the process of changing
these settings.
Configure the leaf device into fabric mode. Configure your device into mixed mode for a mixed VCF .
NOTE: If the leaf device has not previously been configured, also specify the reboot option
to reboot the leaf device now and apply the mode settings. Otherwise, if the leaf device has
been previously configured, in the next step you zeroize and reboot the device to clear prior
configuration stanzas. In that step the reboot also applies the mode settings (maintained
during zeroizing), so you do not need to reboot in this step and again in the next step.
If you are configuring a non-mixed VCF:
user@device>
request virtual-chassis mode fabric local <reboot>
If you are configuring a mixed VCF:
user@device>
request virtual-chassis mode fabric mixed local <reboot>
3. If the leaf device that you are adding to the VCF has not previously been configured, proceed to the
next step.
