If system log messages are configured to be written in structured data, the event logs in J-Web is not populated, and you are unable to view them using Monitor > Events and Alarms > View Events.

Workaround: Use the show log operational mode command for viewing structured-data format files.

  • In the Maintain > Update J-Web page, Select Application package > Update J-Web> local file does not work in Microsoft IE9 and later releases, because of the default security options set on these browsers. As a workaround, increase the security level:

    Method 1:

    1. Navigate to Internet Options > Security.
    2. Select the zone Local intranet.
    3. Click the custom level button.
    4. Disable the option Include local directory Path when uploading file to the server in the Settings > miscellaneous section.
    5. Repeat Steps 3 and 4 for the zone Internet.

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 superuser 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.

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.

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.

  • 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.
