In addition to these server and network interfaces, there are four uplink interfaces to
connect the QFX3500 Node device to Interconnect devices in a QFabric system. These
uplinks use 40-Gbps quad small form-factor pluggable plus (QSFP+) interfaces.
The control plane requires two management ports on the QFX3500 chassis to connect
the Node device to the control plane network.

A QFX3600 Node device provides 16 40-Gbps QSFP+ interfaces. By default, 4 interfaces
(labeled through ) are configured for 40-Gbps uplink connections between your

QFX3600 Node device and your Interconnect device, and 12 interfaces (labeled
through Q15 ) use QSFP+ direct-attach copper (DAC) breakout cables or QSFP+
transceivers with fiber breakout cables to support 48 10-Gigabit Ethernet interfaces for
connections to either endpoint systems or external networks. Optionally, you can choose
to configure the first eight interfaces (
