J-Web Interface—Platform Package

With the J-Web Platform package, you can:

  • Configure Ethernet interfaces.

  • Configure static routing.

  • Configure system properties, such as:

    • User management and authentication management.

    • Management access, such as, HTTPS, HTTP, Telnet, or SSH.

  • Manage software upgrades or schedule a reboot.

J-Web Platform Package—First Look

Each page of the J-Web interface is divided into panes (see Figure 1).

  • Top pane—It is located at the top of the page. It displays the J-Web logo and hostname, tasks–Configure, Monitor, and Maintain, Commit, Update Available logo (if available), and username and Help.

  • Side pane—It is located on the left side of the page. It displays suboptions of the tasks– Configure or Maintain– currently selected in the top pane. Click a suboption to access it in the work area.

  • Work area—This is the main work area of the J-Web interface, located below the top pane and to the right of the side pane. It displays various text boxes, selection boxes, buttons and other options corresponding to the suboption that you select in the side pane. It is the location where you monitor, configure, and manage (maintain) the switch.

The layout of the panes enables you to quickly navigate through the interface. Table 1 summarizes the elements of the J-Web Platform interface.

Commit Options

A set of options using which you can configure committing multiple changes with a single commit.

  • Commit—Commits the candidate configuration of the current user session, along with changes from other user sessions.

  • Compare—Displays the XML log of pending configurations on the device.

  • Discard—Discards the candidate configuration of the current user session, along with changes from other user sessions.

  • Preference—Indicates your choice of committing all configurations changes together or committing each configuration change immediately. The two commit options are:

    • Validate configuration changes—Loads all configuration changes for an accumulated single commit. If there are errors in loading the configuration, the errors are logged. This is the default mode.

    • Validate and commit configuration changes—Sets the system to force an immediate commit on every page after every configuration change.


    There are some pages on which configuration changes must be committed immediately. For such pages, if you configure the commit options for a single commit, the system displays warning notifications that remind you to commit your changes immediately. An example of such a page is the Ports page (Configure > Interfaces > Ports).
