J-Web User Interface for EX-series Switches Overview

You can use two interfaces to monitor, configure, troubleshoot, and manage an EX-series switch: the J-Web graphical user interface and the JUNOS command-line interface (CLI). Both of these user interfaces are shipped with the switch. 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 browser interface. For information about the CLI user interface, see CLI User Interface Overview.

Use Internet Explorer version 6.0 and higher, or Firefox version 2.0 and higher, to access the J-Web interface.

Note: The browser and the network must support receiving and processing HTTP 1.1 GZIP compressed data.

Each page of the J-Web interface is divided into panes.

  • Top pane—Displays system identity information and links.
  • Main pane—Location where you monitor, configure, diagnose (troubleshoot), and manage (maintain) the switch by entering information in text boxes, making selections, and clicking buttons.
  • Side pane—Displays suboptions of the Monitor, Configure, Troubleshoot, or Maintain task currently displayed in the main pane. Click a suboption to access it in the main pane.

The layout of the panes allows you to quickly navigate through the 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 command-line interface (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.
