Supported EX Series Switches

In J-Web Application Package Release 23.2A1, which aligns with Junos OS Release 23.2R1, the J-Web interface supports the EX4400-EM-1C uplink module for EX4400 and EX4400-24X switches. The EX4650 switches as standalone switches, EX2300, EX2300-C, EX2300-MP, EX3400, EX4100, EX4100-F, EX4300-48MP, EX4400, and EX4400-24X switches are also supported from earlier releases.

NOTE: You cannot connect to and perform initial configuration of the EX4650 switches by using the EZSetup procedure from the J-Web interface; you must use EZSetup from the switch console.

To obtain more information about the components that are supported on each switch, and the special compatibility guidelines for the release, see the Hardware Guide for the switch.

To determine the features supported on EX Series switches in this release, use the Juniper Networks Feature Explorer, a Web-based application that helps you to explore and compare Junos OS feature information to find the right software release and hardware platform for your network. Find Feature Explorer at https://apps.juniper.net/feature-explorer/.

Distribution Model

IN THIS SECTION

For Junos OS Release 14.1X53-D10 and later, the J-Web interface is available in two packages:

For information about installing the Application package, see "Upgrading to J-Web Application Package" on page 7.

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.

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.

Table 1 on page 3 lists the release compatibility.

Table 4: Known Limitations

PR Number Problem Description
1513612 For Junos OS release 18.X and 19.X and its service releases, the auto update option is not supported.
Where X is R1, R2, R3, and R4.

NOTE: To disable the auto update information, go to Maintain > Update J-Web page and clear the Check for updates automatically on every login check box under Update Preference.

777372 If a Virtual Chassis contains more than six members, the Support Information page (Maintain > Customer Support > Support information) might not load. This is a known software limitation.
604595 The J-Web interface does not support role-based access control; it supports only users in the super-user authorization class. Therefore, a user who is not in the super-user class, such as a user with view-only permission, is able to launch the J-Web interface and is allowed to configure everything, but the configurations fail on commit, and the switch displays access permission errors. This is a known software limitation.
1026308 If you uninstall the J-Web Platform package by using CLI, reinstalling the Application package will not restore J-Web.
Workaround: Reinstall Junos OS software.
1006208 J-Web software does not compare for appropriateness of the Application package or restrict you from installing inappropriate Application package on top of a Platform or Application package.
Workaround: Install the appropriate J-Web package.
915069 The J-Web interface does not display CLI generated certificates in the Certificate section in the Management Access Configuration page (Configure > System Properties > Management Access). Using J-Web interface you cannot create or edit certificates.
Workaround: Use the CLI interface for accessing certificate related configurations.
400814 In the J-Web interface, you cannot commit some configuration changes in the Ports Configuration page or the VLAN Configuration page because of the following limitations for port-mirroring ports and port-mirroring VLANs:
  • A port configured as the output port for an analyzer cannot be a member of any VLAN other than the default VLAN.
  • A VLAN configured to receive analyzer output can be associated with only one interface.
This is a known software limitation.
Workaround: None.
