EX Series

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.
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.

J-Web Application Package User Guide for EX Series Switches, Release 14.1X53-A1
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, copythe followingconfigurationto 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;
}
}
}
}

Merging a Snippet

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
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; }
Copyright © 2017, Juniper Networks, Inc.xvi
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.

J-Web User Interface for EX Series Switches Overview

Juniper Networks EX Series Ethernet Switches are shipped with the Juniper Networks Junos operating system (Junos OS) installed.
Junos OS has the following primary user interfaces:
J-Web Packages
Juniper Web Device Manager (J-Web) GUI
Junos OS CLI
You can use these interfaces to access, configure, and manage your EX Series switch.
This topic provides an overview of the J-Web interface. For information about the CLI, see CLI User Interface Overview.
For Junos OS Release 14.1X53-D10 and later, the J-Web interface is available in two packages:
Platform package—Provides basic features of J-Web and is installed as part of Junos OS.
Application package—Provides complete features of J-Web and is an installable package.
Platform Package
3Copyright © 2017, Juniper Networks, Inc.
J-Web Application Package User Guide for EX Series Switches, Release 14.1X53-A1
The Platform package of J-Web is installed as part of Junos OS that is shipped with your EX Series switch. The Platform package provides the basic features of the J-Web interface. The Platform package enables you to configure and maintain your switch.
Application Package
The Application packageis not installedby default on your switch. You must download it and install it over the Platform package on your switch. The Application package provides all the features of the J-Web interface that enable you to configure, monitor, maintain, and troubleshoot your switch.
The Platform package, which is installed as part of the Junos OS that is shipped with your switch, follows the Junos OS release cycle. However, the Application packages have their own release cycle which is independent of the Junos OS release cycle. This separate release cycle helps you get the latest features of J-Web by installing the latest version of the Application package, without waiting for Junos OS releases.
NOTE: The J-Web Application package is hot-pluggable. You can install it
on top of the current Junos OS installation, and you need not reboot the switch after the installation.
If your current J-Web package is:

Release Compatibility
NOTE: To determine which J-Web package you are currently using, click Help
> About. The About window appears. If you are using a Platform package,
only the Platformpackagedetails are displayed.If you are using an Application package, then the Platform package and Application package details are displayed.
Then you can:
Upgrade to the Application package.Platform package
Update to a latest version of the Application package available on the Juniper Networks server that is compatible with the Junos OS on your switch.
NOTE: If you upgrade Junos OS on your switch, the current J-Web package is replaced with
the J-Web Platform package that is associated with the upgraded Junos OS release. You can then install the latest Application package that is associated with the main release of the upgraded Junos OS, over the Platform package.
The Application packages of J-Web have their own release cycles (A1, A2, A3, and so on), which are independent of the Junos OS release cycle. An Application package is compatible only with the corresponding major release of Junos OS.
The Table 3 on page 5 illustrates the example of the release compatibility.
Copyright © 2017, Juniper Networks, Inc.4
Table 3: J-Web Release Compatibility Matrix
Associated J-Web Application Package ReleaseJunos OS Release
Application package 14.1X53-A114.1X53-D10

Application package 15.1A115.1R1
Chapter 1: Overview
15.1R3
Any available later version of the Application package for a Junos OS release supersedes the earlier version. Thus, if Application package version 15.1A2 is available for 15.1R1, it will supersede version 15.1A1. We recommend that you install the latest available version of the Application package.
Software Requirements
To access the J-Web interface, your management device requires the following software:
Application package 15.1A2
NOTE: Application package 15.1A2 cannot be installed on Junos OS Release 15.1R1.
Application package 15.1A3 (if applicable)
16.1A116.1R1
Supportedbrowsers—MicrosoftInternet Explorer version 9 or 10, MozillaFirefoxversion 24 through 30, and Google Chrome version 27 through 36.
TIP: For best viewing of the J-Web user interface, set the screen resolution
to 1440 X 900 pixels.
NOTE: Other browser versions might not work on the switch. The browser
and the network must support receiving and processing HTTP 1.1 GZIP compressed data.
Language support—English-version browsers
