Requesting Technical Support | xvi
Use this guide to plan, install, perform initial software configuration, perform routine maintenance, and to
troubleshoot QFX5220 switches.
After completing the installation and basic configuration procedures covered in this guide, refer to the
Junos OS documentation for further software configuration.
Documentation and Release Notes
To obtain the most current version of all Juniper Networks®technical documentation, see the product
documentation page on the Juniper Networks website at https://www.juniper.net/documentation/.
If the information in the latest release notes differs from the information in the documentation, follow the
product Release Notes.
Juniper Networks Books publishes books by Juniper Networks engineers and subject matter experts.
These books go beyond the technical documentation to explore the nuances of network architecture,
deployment, and administration. The current list can be viewed at https://www.juniper.net/books.
Using the Examples in This Manual
If you want to use the examples in this manual, you can use the load merge or the load merge relative
command. These commands cause the software to merge the incoming configuration into the current
candidate configuration. The example does not become active until you commit the candidate configuration.
xi

If the example configuration contains the top level of the hierarchy (or multiple hierarchies), the example
isafull example. In this case, use the load merge command.
If the example configuration does not start at the top level of the hierarchy, the example is a snippet. In
this case, use the load merge relative command. These procedures are described in the following sections.
Merging a Full Example
To merge a full example, follow these steps:
1. From the HTML or PDF version of the manual, copy a configuration example into a text file, save the
file with a name, and copy the file to a directory on your routing platform.
For example, copy the following configuration to a file and name the file ex-script.conf. Copy the
ex-script.conf file to the /var/tmp directory on your routing platform.
system {
scripts {
commit {
file ex-script.xsl;
}
}
}
interfaces {
fxp0 {
disable;
unit 0 {
family inet {
address 10.0.0.1/24;
}
}
}
}
2. Merge the contents of the file into your routing platform configuration by issuing the load merge
configuration mode command:
[edit]
user@host# load merge /var/tmp/ex-script.conf
load complete
xii

Merging a Snippet
To merge a snippet, follow these steps:
1. From the HTML or PDF version of the manual, copy a configuration snippet into a text file, save the
file with a name, and copy the file to a directory on your routing platform.
For example, copy the following snippet to a file and name the file ex-script-snippet.conf. Copy the
ex-script-snippet.conf file to the /var/tmp directory on your routing platform.
commit {
file ex-script-snippet.xsl; }
2. Move to the hierarchy level that is relevant for this snippet by issuing the following configuration mode
command:
[edit]
user@host# edit system scripts
[edit system scripts]
3. Merge the contents of the file into your routing platform configuration by issuing the load merge
relative configuration mode command:
[edit system scripts]
user@host# load merge relative /var/tmp/ex-script-snippet.conf
load complete
For more information about the load command, see CLI Explorer.

The QFX5220 line of switches offer two spine-and-leaf models for data centers requiring 100-Gigabit
Ethernet and 400-Gigabit Ethernet speeds.
QFX5220-128C Switch Description
The QFX5220-128C offers 128 ports of 100-Gigabit Ethernet in a 4-U form factor. With 12.8 terabits per
second (Tbps) bandwidth, the QFX5220-128C is optimally designed as a data aggregation or top-of-rack
switch for small to medium size data centers and Massively Scalable Data Center (MSDC) deployments.
The 100-Gigabit Ethernet ports can be configured either for 100-Gbps or 40-Gbps speeds. The 100-Gbps
ports can also be channelized into 4 x 25 Gbps or 4 x 10 Gbps. There are two dedicated small-form factor
plugable plus (SFP+) ports for 10 Gigabit or 1 Gigabit Ethernet support.
An Intel Xeon D-1518 processor drives the QFX5220 control plane, which runs the Junos OS Evolved
software. The Junos OS Evolved software image is stored on two internal 50-GB solid-state drives (SSDs).
The QFX5220-128C is available with ports-to-FRUs airflow (Airflow Out) and with AC or DC power
supplies.

Benefits of the QFX5220-128C
•Serves the spine layer needs of a wide range of enterprises. Examples include: cloud and high-performance
computing data centers; Software as a Service (SaaS) providers; streaming video service providers; cable
operators; financial service providers and enterprises that run large-scale Web applications, analytics,
and deep learning workloads.
•Supports IEEE 1588 Precision Time Protocol (PTP), Transparent Clock, and hardware timestamping for
distributing precise time and frequency over packet networks. PTP is an important prerequisite in
real-time sensitive workloads such as those employed in financial trading, real-time video streaming,
and broadcasting networks.
•Aligns well with the needs of data centers whose aggregate traffic comprises lossless classes of traffic
such as access to a remote flash storage, support for advanced congestion control, and flow-aware traffic
scheduling support.
