J-Web User Interface for EX Series Switches Overview

J-Web Packages

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.

1. Platform Package

   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.

2. Application Package

   The Application package is not installed by 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.

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 Platform package details are displayed. If you are using an Application package, then the Platform package and Application package details are displayed.

If your current J-Web package is:	Then you can:
Platform package	Upgrade to the Application package.
Application 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.

Release Compatibility

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 1 illustrates the example of the release compatibility.

Table 1: J-Web Release Compatibility Matrix

Junos OS Release	Associated J-Web Application Package Release
14.1X53-D10	Application package 14.1X53-A1
14.1X53-D35	Application package 14.1X53-A2
15.1R1	Application package 15.1A1
15.1R3	Application package 15.1A2 Note: Application package 15.1A2 cannot be installed on Junos OS Release 15.1R1. Application package 15.1A3 (if applicable)
16.1R1	16.1A1
17.1R1	Application package 17.1A1
17.2R1	Application package 17.2A1
17.3R1	Application package 17.3A1
15.1X53-D57	Application package 15.1X53-A2
17.4R1	Application package 17.4A1
18.1R1	Application package 18.1A1
18.1R2	Application package 18.1A2
18.2R1	Application package 18.2A1
18.3R1	Application package 18.3A1
18.4R1	Application package 18.4A1

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.

Note:

If you are using Junos OS Release 22.4R1, you must upgrade to 22.4R3-S2 or later before you install Application Package 22.4A2.

  Tip:

  For best viewing of the J-Web user interface, set the screen resolution to 1440 X 900 pixels.
