•
Flexibility—You can easily expand the size of your VCF by adding devices to the fabric as your networking
needs grow.
•
Investment protection—In environments that need to expand because the capabilities of a traditional
QFX Series Virtual Chassis are maximized, a VCF is often a logical upgrade option because it enables
the system to evolve without having to remove existing, previously purchased devices from the network.
•
Manageability—VCF provides multiple features that simplify configuration and management. VCF, for
instance, has an autoprovisioning feature that enables you to plug and play devices into the fabric after
minimal initial configuration. VCF leverages many of the existing configuration procedures from a Virtual
Chassis, so that you can configure and maintain a VCF easily if you are already familiar with the procedures
for configuring and maintaining a Virtual Chassis.
