If you are using the QFX3600 device as a standalone switch, by default, all 16 QSFP+
ports ( through

you can choose to configure each port to operate as 10-Gigabit Ethernet (xe) ports.
The number of ports supported is release dependent. See Configuring the Port Type
on QFX3600 Standalone Switches for your release for more information about
configuring the port type. You can use QSFP+ direct-attach copper (DAC) cables,
QSFP+ DAC breakout cables, or QSFP+ transceivers. You can use QSFP+ transceivers
to create four 10-Gigabit Ethernet ports by using a fiber breakout cable to distribute
the interfaces to four 10GBASE-SR SFP+ transceivers. (Juniper Networks does not
sell fiber breakout cables, they must be purchased separately.) See Determining
Interface Support for the QFX3600 Device.
