J-Web User Interface for EX Series Switches Overview

You can use two interfaces to monitor, configure, troubleshoot, and manage a Juniper Networks EX Series Ethernet Switch: the J-Web graphical user interface and the Juniper Networks Junos operating system (Junos OS) 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.

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

Supported browsers—Microsoft Internet Explorer version 7.0 and Mozilla Firefox version 3.0
Note: Other browser versions might not work on the switch. The browser and the network must support receiving and processing HTTP 1.1 GZIP compressed data.
Language support—English-version browsers
Supported OS—Microsoft Windows XP Service Pack 3

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 OS 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.

J-Web Interface Element	Description
Main Pane
Top Pane
Host	The hostname of the switch.
Logged in as: username	The user name you used to log in to the switch.
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: Commit changes immediately—Sets the system to force an immediate commit on every page after every configuration change. Validate changes until explicit commit—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. 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, the system displays warning notifications that remind you to commit your changes immediately. An example for such a page is Switching.
Help	Displays links to information on help and the J-Web interface. Help Contents—View context-sensitive help topics. About—Displays information about the J-Web interface, such as the version number.
Logout	Ends your current login session with the switch and returns you to the login page.
Taskbar	Menu of J-Web main options. Click the tab to access an option. Dashboard—Displays a high-level, graphical view of the chassis and status of the switch. It displays system health information, alarms, and system status. Configure—Configure the switch, and view configuration history. Monitor—View information about configuration and hardware on the switch. Maintain—Manage files and licenses, upgrade software, and reboot the switch. Troubleshoot—Run diagnostic tools to troubleshoot network issues.
Help (?) icon	Displays useful information—such as the definition, format, and valid range of an option—when you move the cursor over the question mark.
Red asterisk (*)	Indicates a required field.
Icon legend	(Applies to the Point & Click CLI editor only) Explains icons that appear in the user interface to provide information about configuration statements: C—Comment. Move your cursor over the icon to view a comment about the configuration statement. I—Inactive. The configuration statement does not apply for the switch. M—Modified. The configuration statement has been added or modified. *—Mandatory. The configuration statement must have a value.
Task Pane
Configuration hierarchy	(Applies to the Junos OS CLI configuration editor only) Displays the hierarchy of committed statements in the switch configuration. Click Expand all to display the entire hierarchy. Click Hide all to display only the statements at the top level. Click plus signs (+) to expand individual items. Click minus signs (-) to hide individual items.
