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.

x

If the example configuration contains the top level of the hierarchy (or multiple hierarchies), the example

is a full 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

xi

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.

Benefits and Uses of NFX350 | 23

The Juniper Networks NFX350 Network Services Platform is a secure, automated, software-driven universal

customer premises equipment (uCPE) platform that delivers virtualized network and security services on

demand. Leveraging Network Functions Virtualization (NFV) and built on the Juniper Cloud CPE solution,

NFX350 enables service providers to deploy and chain multiple, secure, high-performance virtualized

network functions (VNFs) on a single device.

The NFX350 is suited for large and extra-large deployments. The NFX350 is a high-end resilient uCPE

platform that can be used in secure SD-WAN and secure router deployments.

Figure 1 on page 18 shows the front panel of the NFX350 device.

NFX350 Hardware

The NFX350 portfolio consists of rack-mount models, with LTE support. The NFX350 device has a 1 U

form factor and comes with built-in fans and power supply.

The NFX350 device can be used as:

•

A SD-WAN solution.

•

A resilient uCPE platform.

•

An integrated branch router and switch, extensible with VNFs.

•

A CPE for service providers.

•

A secure router for distributed enterprises.

System Software

The NFX350 architecture integrates routing, switching, and security functions on a single platform that

optimizes the usage of system resources. The architecture enables unified management of all the

components through a single CLI. Key components in the NFX350 software include the Junos Control

Plane (JCP), Juniper Device Manager (JDM), Layer 2 dataplane, Layer 3 dataplane, and Virtual Network

Functions (VNFs). The JCP is the Junos virtual machine (VM) running on the host OS, Wind River Linux.

The JCP functions as the single point of management for all the components. The JCP CLI is displayed

when you log in to the NFX350 device.
