You can use the 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 EX Series Virtual Chassis Overview. For more
information about VCFs, see Virtual Chassis Fabric Overview.
The 24-port and 48-port EX4300 switches provide one slot for installing an optional
uplink module. The 32-port EX4300 switches provide two slots for installing an optional
uplink module. You can either use the uplink module ports to connect the switch to other
devices or configure these ports as VCPs and use them to interconnect EX4300 switches
to form a Virtual Chassis or a VCF.
