Four-Level Interface Naming Convention
When you configure an interface on the QFabric system, the interface name needs to
follow a four-level naming convention that enables you to identify an interface as part
of either a Node device or a Node group. Include the name of the network or server Node
group at the beginning of the interface name.
The four-level interface naming convention is:
device-name : type-fpc/pic/port
where device-name is the name of the Node device or Node group. The remainder of the
naming convention elements are the same as those in the QFX3500 switch interface
naming convention.
An example of a four-level interface name is:
node2 : xe-0/0/2
QSFP+ Interfaces
The QFX3500 Node device provides four 40-Gbps QSFP+ (quad small form-factor
pluggable plus) interfaces (labeled
Q0
through
Q3
) for uplink connections between your
Node device and your Interconnect devices.
The QFX3600 Node device provides 16 40-Gbps QSFP+ interfaces. By default, 4 interfaces
(labeled
Q0
through
Q3
) are configured for 40-Gbps uplink connections between your
Node device and your Interconnect devices, and 12 interfaces (labeled
Q4
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 (such as servers and storage devices) or external networks. Optionally,
you can choose to configure the first eight interfaces (Q0 through Q7) for uplink
connections between your Node device and your Interconnect devices, and interfaces
Q2 through Q15 for 10-Gigabit Ethernet connections to either endpoint systems or external
