This procedure applies to QFX Series Virtual Chassis. For the procedure on adding a
switch to a Virtual Chassis Fabric (VCF), see Adding a Device to a Virtual Chassis Fabric.
You can use this procedure to add a device in a supported combination to an existing
Virtual Chassis. A QFX Series Virtual Chassis can be composed of one type of QFX Series
switch or a supported combination of QFX Series switches interconnected using Virtual
Chassis ports (VCPs). QFX series switches that can be members of a Virtual Chassis
include QFX3500, QFX3600, QFX5100, or QFX5110 switches. EX4300 switches can also
be members of a mixed QFX Series Virtual Chassis with QFX 3500, QFX3600, or QFX5100
switches. See Understanding Mixed EX Series and QFX Series Virtual Chassis or Virtual
Chassis Fabric for details on the types and combinations of switches that can make up
a mixed QFX Series Virtual Chassis.
Before you begin, be sure you have:
Mounted the new switch in a rack.
Enabled automatic software update on the Virtual Chassis. See Configuring Automatic
Software Update on Virtual Chassis Member Switches (CLI Procedure).
CAUTION: When adding a QFX5100 switch that is installed with a "-qfx-5-"
Junos OS image to a QFX5110 Virtual Chassis, you must first upgrade the
QFX5100 switch before this step in the procedure so it is running a "-qfx-5e-"
Junos OS image. The automatic software update feature cannot
automatically update a QFX5100 switch running a "-qfx-5-" Junos OS
image to a "-qfx-5e-" image. See Upgrading a QFX5100 Switch with a USB
Device to Join a QFX5110 Virtual Chassis or Virtual Chassis Fabric
If you are expanding a preprovisioned configuration, made a note of the serial number
(the number is on the back of the switch). You will need to edit the Virtual Chassis
configuration to include the serial number of the new member switch.
