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-PFLlicense 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.
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.
You manage the switch using the Junos OS command-line interface (CLI), accessible
through the console and out-of-band management ports on the device.
