Juniper EX4300 Hardware Guide

•
All QFX5100 members–in a ring topology this is Virtual Chassis; in a spine and leaf
topology this is a Virtual Chassis Fabric (VCF). For a cabling example of spine and leaf,
see Connecting a QFX5100 Device in a Virtual Chassis Fabric.

A mixture of QFX5100, QFX3600, QFX3500, and EX4300 members. EX4300 switches
as the master or backup is not supported; use QFX5100 switches in these roles
whenever possible.
An all EX4300 member is simply considered an EX4300 Virtual Chassis. See
Understanding EX4300 Virtual Chassis.
If the QSFP+ interfaces are not available for VCP, 10-Gigbit interfaces can be used.
All members of the Virtual Chassis are required to run the same Junos OS Release. You
can check the version and release by issuing the show chassis version CLI command.
Cabling QFX3500 Switches in a QFX Virtual Chassis
Figure 59 on page 202 is the preferred cabling method using the 40-Gigabit QSFP ports.
See Figure 60 on page 203 for an alternative method using the 10-Gigabit SFP+ ports.
