You can use the built-in QSFP+ ports as network ports or as VCPs to connect the switch in a Virtual
Chassis or a VCF. By default, the built-in QSFP+ ports are configured as VCPs. You can also use the
uplink module ports to connect members of a Virtual Chassis or a VCF across multiple wiring closets by
configuring these ports as VCPs. For more information about Virtual Chassis, see
