Determining Interface Support for the QFX3600 Device

The QFX3600 device provides 16 QSFP+ ports, which support QSFP+ transceivers and QSFP+ DAC or
DAC breakout cables.
On a QFX3600 Node device in a QFabric system, four ports (labeled Q0 through Q3) operate as 40-Gbps
data uplink (fte) ports for uplink connections between your QFX3600 Node device and your Interconnect
device. Twelve ports (labeled Q4 through Q15) operate in 10-Gigabit Ethernet (xe) mode to support 48
10-Gigabit Ethernet interfaces for connections to either endpoint systems or external networks. Optionally,
you can choose to configure ports Q0 through Q7 to operate as 40-Gbps data uplink (fte) ports, and ports
Q2 through Q15 to operate in 10-Gigabit Ethernet (xe) or 40-Gigabit Ethernet (xle) mode. See Configuring
the Port Type on QFX3600 Node Devices for more information.
On a QFX3600 standalone switch, ports Q0 through Q15 operate as 40-Gigabit Ethernet (xle) ports.
Optionally, you can choose to configure ports Q0 through Q15 to operate as 10-Gigabit Ethernet (xe)
ports. See Configuring the Port Type on QFX3600 Standalone Switches for more information.
NOTE: On a QFX3600 standalone switch, you can either configure up to 63 or 64 10-Gigabit
Ethernet ports on ports Q0 through Q15, depending on the Junos OS release running on the
switch. See the Channelizing Interfaces topic for your specific Junos OS release for further details.
You can use SFP transceivers to connect the QFX3600 device to a management network, or the control
plane and management network of a QFabric system. The 1000BASE-SX Gigabit Ethernet SFP module
(QFX-SFP-1GE-SX) is supported in the SFP management ports labeled C0S and C1S. The QFX3600 device
also has two 1000BASE-T RJ-45 management ports (labeled C0 and C1), which can be used to connect
the QFX3600 device to a management network, or the control plane and management network of a
QFabric system.
