Interface Support for the QFX3500 Device
Supported Platforms
QFabric System
The 48 small form-factor pluggable plus (SFP+) access ports in the QFX3500 device
support SFP and SFP+ transceivers, as well as SFP+ direct-attach copper (DAC) cables.
The four quad small form-factor pluggable plus (QSFP+) uplink ports in the QFX3500
device support QSFP+ transceivers, as well as QSFP+ DAC and DAC breakout cables.
When the QFX3500 device is operating as a standalone switch, each QSFP+ port can
be configured to operate as 10-Gigabit Ethernet interfaces or a single 40-Gigabit Ethernet
interface. By default, the uplink ports on a standalone switch are configured as 10-Gigabit
Ethernet interfaces.
NOTE: Port Q0 of the QSFP+ uplink ports only supports three of four
10-Gigabit Ethernet interfaces. Ports Q1 through Q3 support four of the
10-Gigabit Ethernet interfaces. Together, the four QSFP+ ports provide up
to 15 10-Gigabit Ethernet interfaces.
Figure 14 on page 100 shows the uplink ports and lists the interfaces created on each port
when they are configured as 10-Gigabit Ethernet interfaces.

See the topic on Channelizing Interfaces for your Junos Release.
If your QFX3500 device has an SFP management board instead of the 1000BASE-T
RJ-45 management board, you can use the SFP transceivers to connect the QFX3500
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 in the following software releases:
•
Junos OS 12.1X49-D1 or later for the QFX3500 device as a standalone switch
•
Junos OS 12.2X50-D10 or later for the QFX3500 Node device in a QFabric system
Table 26 on page 101 lists the supported transceivers and the software release in which
they were first supported.
