Interface Support for the QFX3500 Device

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: Ports Q1 through Q3 support four of the 10-Gigabit Ethernet interfaces. Together, the three QSFP+ ports provide up to 12 10-Gigabit Ethernet interfaces. Port Q0 also supports 10-Gigabit Ethernet interfaces, but the number of interfaces supported depends on the release of Junos OS running on the switch. Some Junos OS releases support three 10-Gigabit Ethernet interfaces, others support four. See the topic on Channelizing Interface for your specific release.

Figure 1 shows the uplink ports and lists the interfaces created on each port when they are configured as 10-Gigabit Ethernet interfaces.

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 1 lists the supported transceivers and the software release in which they were first supported.
