On EX4300 switches, the structured-data format for system log messages is not supported in the J-Web interface. 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.

Table 4: Known Limitations
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.
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.
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, the Ethernet Switching Monitor page (Monitor > Switching > Ethernet Switching) might not display monitoring details if the switch has more than 13,000 MAC entries. This is a known software limitation.
When you try to commit your changes to the switch from your laptop by using the EZsetup procedure, the status of the commit operation is displayed as Success, even if the laptop is disconnected from the switch.
Workaround: Reconnect your laptop to the switch and commit the changes again.
