In a QFX Virtual Chassis, you can connect up to 10 standalone QFX5100, QFX3600, QFX3500, and
EX4300 switches except EX4300-48MP and EX4300-48MP-S switches into a QFX Series Virtual
Chassis and manage the interconnected switches as a single chassis. Unlike a Virtual Chassis Fabric
(VCF), which is cabled in a spine and leaf topology, the QFX Virtual Chassis is cabled in a ring topology.
For Virtual Chassis Fabric cabling examples, see Connecng a QFX5100 Device in a Virtual Chassis
Fabric.
As of Junos Release 17.3R1, you can also connect select models of the QFX5100 in the line card role in
a QFX5110 Virtual Chassis. See Connecng QFX5110 and QFX5100 Members in a QFX5110 Virtual
Chassis.
This topic describes how to cable QFX Series switches and EX4300 switches into a QFX Virtual Chassis.
Before You Start
You congure a QFX Series Virtual Chassis by conguring the switch interfaces into Virtual Chassis ports
(VCPs). VCPs connect switches together to form a Virtual Chassis, and are responsible for passing all
data and control trac between member switches in the Virtual Chassis. All non-channelized QSFP+
uplink interfaces on standalone QFX5100 switches can be congured into VCPs. All xed SFP+
interfaces on QFX5100-96S switches can also be congured into VCPs.
Use the following interfaces to create VCPs:
• On QFX5100, non-channelized QSFP+ uplink interfaces. All xed SFP+ interfaces on the
QFX5100-96S switches are also available.
• On EX4300 switches, the built-in QSFP+ ports are dedicated VCPs by default. In 48-port EX4300
switches except EX4300-48MP and EX4300-48MP-S switches, you can use the QSFP+ ports as
network ports or as VCPs. You can also use the SFP+ uplink module ports as VCPs by conguring
these ports as VCPs.
