Release Notes: J-Web Application Package Release 15.1A2 for Juniper Networks EX Series Ethernet 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:

  • 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 newly re-designed J-Web interface. For information about the CLI, see CLI User Interface Overview.

Supported EX Series switches

In Junos OS Release 15.1R3, the J-Web interface supports EX2200, EX3300, EX4200, EX4300, EX4500, EX4550, and EX6200 switches.

Note: You cannot connect to and perform initial configuration of EX2200-24T-4G-DC switches by using the EZSetup procedure from the J-Web interface. For EX2200-24T-4G-DC switches, you must use EZSetup from the switch console.

New Features for J-Web

New Distribution Model

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

    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 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.

For information about installing the Application package, see Upgrading to J-Web Application Package.

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, both 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.

    Tip: We recommended a screen resolution of 1440 X 900 pixels.

  • Language support—English-version browsers

Known Limitations

This section lists the known limitations in J-Web:

  • For EX Series switches, in the J-Web interface, the username field on the Login screen does not accept HTML tags or the < and > characters. The following error message appears: A username cannot include certain characters, including < and >.
  • When you use an HTTPS connection in the Microsoft Internet Explorer browser to save a report from certain pages in the J-Web interface, the error message Internet Explorer was not able to open the Internet site is displayed. This problem occurs because the Cache-Control: no cache HTTP header is added on the server side, and Internet Explorer does not allow you to download the encrypted file with the Cache-Control: no cache HTTP header set in the response from the server.

    As a workaround, refer to Microsoft Knowledge Base article 323308, which is available at http://support.microsoft.com/kb/323308. Alternatively, use HTTP in the Internet Explorer browser or use HTTPS in the Mozilla Firefox browser to save a file from one of these pages.
