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 29. 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 switchto 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.
QFX5110 switches employ the security feature, Secure Boot, which is based on the UEFI
2.4 standard. The BIOS has been hardened and serves as a core root of trust. The BIOS
updates, the bootloader, and the kernel are cryptographically protected. No action is
required to implement Secure Boot.
If a premium or advanced feature is configured on the QFX5110 without a valid license,
an alarm is raised and system log (syslog) messages are generated.
For more information about which features are supported on QFX Series devices, see
Feature Explorer.
