QFX5110-32Q Hardware
As shown in Figure 3 on page 14 , the QFX5110-32Q is a flexible configuration switch allowing either 32
ports of 40-Gigabit Ethernet quad small form-factor pluggable plus (QSFP+) or 20 ports of QSFP+ and 4
ports of high-density 100-Gigabit Ethernet quad small form-factor pluggable solution (QSFP28). Each
QSFP+ port can operate as a native 40-Gigabit Ethernet port, or as four independent 10-Gigabit Ethernet
ports when using breakout cables. The four QSFP28 ports are available either as access ports or as uplinks.
The QFX5110-32Q can be channelized using one of the available system modes. For full details on the
different port channelization modes, see “QFX5110-32Q Port Panel” on page 18 . The QFX5110-32Q
switch provides an aggregate throughput of 2.56 Tbps.

System Software
QFX Series devices use the Junos operating system (OS), which is installed on a QFX5110 switch’s 64-GB
internal solid-state flash drive. The same Junos OS code base that runs on QFX5110 switches also runs
on all Juniper Networks EX Series switches, and M Series, MX Series, and T Series routers.
The QFX5110-48S switch is supported on Junos OS Release 15.1X53-D210 and later; the QFX5110-32Q
is supported on Junos OS 17.2R1 and later.
Software features are categorized into three tiers: base, premium, and advanced:
•
Junos OS base features such as Layer 2 and Layer 3 switching, multicast, automation, programmability,
Zero Touch Provisioning (ZTP), and basic monitoring are enabled by default from the factory.
•
Junos OS premium features such as Border Gateway Protocol (BGP), Intermediate System-to-Intermediate
System (IS-IS), and Virtual Extensible Local Area Network (VXLAN) require a QFX5K-C1-PFL license on
each QFX5110 switch to use these features.
•
Junos OS advanced features include Multiprotocol Label Switching (MPLS) in addition to all of the
premium features. A QFX5K-C1-AFL license is required on each QFX5110 switch to use these features.
When using QFX5110 switches in a QFX5110 VCF, PFL and AFL licenses are required on the spine device:
leaf devices do not require licensing.
