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.

| 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.
