Determining Interface Support for the QFX5100 Device

All product SKUs of the QFX5100 supply quad small form-factor pluggable plus (QSFP+) ports for use as
uplinks, as access ports, or as Virtual Chassis ports (VCPs). These 40 GbE ports support QSFP+ transceivers,
QSFP+ direct-attach copper (DAC) cables, and DAC breakout cables (DACBO). The QFX5100-48S has 6
QSFP+ ports; the QFX5100-96S has 8 QSFP+ ports; the QFX5100-24Q has 24 built-in QSFP+ ports that
can all be used as uplinks. The You can also add two QFX-EM-4Q expansion modules to the QFX5100-24Q
for additional QSFP+ uplink ports. Each QSFP+ port on a QFX5100-24Q can be configured to operate as
10-Gigabit Ethernet interface by using a breakout cable or as a single 40-Gigabit Ethernet interface. See
Configuring the QSFP+ Port Type on QFX5100 Devices for more information.
On all QFX5100 product SKUs, the ports are enabled by default and the default config adds the ports to
the default VLAN.
Downlink ports are product SKU-specific:
QFX5100-96S–has 96 small form-factor pluggable plus (SFP+) ports that support SFP and SFP+
transceivers, as well as DAC cables.
QFX5100-48S–has 48 SFP+ ports that support SFP and SFP+ transceivers, as well as DAC cables.
QFX5100-48T–has 6 QSFP+ uplink ports.
QFX5100-24Q–has 24 QSFP+ access ports that can be configured to operate as 10-Gigabit Ethernet
interfaces or as a single 40-Gigabit Ethernet interface.
QFX5100-24Q-AA–has 24 QSFP+ access ports that can be configured to operate as 10-Gigabit Ethernet
interfaces or as a single 40-Gigabit Ethernet interface.
