Removing a Device From a Virtual Chassis Fabric

 

This topic describes how to remove a device from a Virtual Chassis Fabric (VCF):

To remove a device from a VCF:

  1. Power off the device that you are removing from the VCF.
  2. Uncable the device that you are removing from the VCF.
  3. Log in to the Virtual Management ethernet (VME) interface. Remove the device from the VCF configuration.

    You can skip this step if you are removing a device that was never configured.

    [edit virtual-chassis]

    user@device# delete member member-id

  4. Delete the Virtual Chassis port (VCP) or ports on the devices that are still in the VCF but were connected to the removed device.
    user@device> request virtual-chassis vc-port delete pic-slot pic-slot port port-number member member-id

    When a device is removed from a VCF, the interface on the other end of the VCP link that was connected to the removed device remains configured as a VCP.

    You can check the results of this command using the show virtual-chassis vc-port command.

  5. (Required only if you are removing a device that turns a mixed VCF into a homogenous VCF) Log in to the VCF and disable mixed mode for all of the devices in the VCF, Configure all devices to reboot to complete this procedure.
    user@device> request virtual-chassis mode mixed disable all-members reboot

    This step should only be taken if you are removing a QFX3600, QFX3500, or EX4300 device from a mixed QFX5100 VCF and the only devices remaining in the VCF are QFX5100 devices.

    The VCF experiences downtime as part of the reboot procedure.

  6. Commit the configuration.
    [edit]

    user@device# commit
  7. Power on the device that was removed from the VCF, and log in to it.
  8. (Optional, but recommended) Delete the VCP or VCPs on the device that was removed:
    user@device> request virtual-chassis vc-port delete pic-slot pic-slot port port-number member member-id
  9. (Optional, but recommended) Reset the fabric and mixed mode settings.

    If you are removing a device that was part of a VCF composed entirely of the same device:

    user@device> request virtual-chassis mode fabric disable reboot

    If you are removing a device that was part of a mixed VCF:

    user@device> request virtual-chassis mode fabric mixed disable reboot

    Reboot the device to complete the process.

    We recommend resetting the fabric and mixed mode settings immediately after removing it from the VCF to avoid any potential issues with your device if it is placed in your network in another role.
