The J-Web Interface for the QFX Series Overview

The Juniper Networks QFX Series ships with two pre-installed interfaces—the Juniper Networks Junos OS command-line interface (CLI), and the J-Web interface. You can use either interface to monitor, configure, troubleshoot, and manage the Juniper Networks QFX Series. This topic describes the J-Web interface. You can navigate the J-Web interface, scroll pages, and expand and collapse elements as you do in a typical Web-based application.

To access the J-Web interface for the switch, your management device requires the following software:

Each J-Web interface page is divided into panes.

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

The J-Web interface provides CLI tools that allow you to perform all of the tasks that you can perform from the Junos OS CLI, including a CLI Viewer to view the current configuration, a CLI Editor for viewing and modifying the configuration, and a Point & Click CLI editor that allows you to click through all of the available CLI statements.

Commit Options

Set of options using which you can configure committing multiple changes with a single commit operation.

  • 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 configuration changes together, or committing each configuration change immediately. The two commit options are:

    • Commit changes immediately—Sets the system to force an immediate commit operation on every page after every configuration change.
    • Validate changes until explicit commit—Loads all configuration changes for an accumulated single commit operation. If there are errors in loading the configuration, the errors are logged. This is the default mode.

    Note: 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 operation, the system displays warning notifications that remind you to commit your changes immediately. An example for such a page is Switching.
