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.
Uplink Modules
EX4300 switches provide one slot for installing an optional uplink module. You can use
the uplink module ports either 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 configuration by using SFP+ transceivers.
Table 6 on page 10 lists the uplink modules supported on 24-port and 48-port EX4300
switch models. Table 7 on page 10 lists the uplink modules supported on 32-port EX4300
switch models.
