Adding A Spine Or Leaf Device To A Preprovisioned Virtual Chassis Fabric - Juniper QFX5110 Series Hardware Documentation

NOTE: We recommend setting the fabric and mixed mode settings before interconnecting
your devices into a VCF to avoid the following issues:
Incurring downtime as the devices reboot to commit the mixed mode or fabric settings.
Manually correcting potential issues related to VCF formation because the device did not
immediately join the VCF.
You can, however, use the request virtual-chassis mode fabric local or request virtual-chassis
mode mixed local commands to set a device into fabric or mixed mode after interconnecting
your VCF.
7. (Required only if you are adding a device that turns a non-mixed VCF into a mixed VCF) Log in to the
VCF and set all devices in the VCF to mixed mode. Configure all devices to reboot to complete this
procedure.
user@device> request virtual-chassis mode mixed all-members reboot
The VCF experiences downtime as part of the reboot procedure.
8. After the device reboots, interconnect the new device into the VCF by cabling the device to the leaf
devices in the VCF using supported interfaces that can be VCPs.
The interconnecting links are converted into VCPs automatically.
The new spine device should be operational after the cabling is completed.

Adding a Spine or Leaf Device to a Preprovisioned Virtual Chassis Fabric

To add a spine or leaf device to a preprovisioned VCF:
1. Log in to your VCF.
2. If you are replacing a device that is already part of the VCF, power off the device in the VCF.
Follow the steps in "Removing a Device From a Virtual Chassis Fabric" on page 405
from the VCF.
3. Modify the configuration.
If your new device is replacing an existing device, modify the configuration to remove the old device.
You can skip this portion of the procedure if you are not replacing an existing device.
