J-Web Interface—Application Package
This topic applies only to the J-Web Application package.
With the J-Web Application package, you can:
Get a high-level, graphical view of the chassis and the status of the switch, such as the system health information, alarms, or system status.
Configure the switch, and view the configuration history.
Monitor the switch by viewing information about configuration and hardware on the switch such as events, alarms, security, and routing options.
Maintain the switch by updating the J-Web interface, upgrading Junos OS, uploading configurations, managing licenses and files, or rebooting the switch.
Juniper Networks devices require a license to activate the feature. To understand more about managing licences through J-Web, see, Licenses for Network Management. Please refer to the Licensing Guide for general information about License Management.
Troubleshoot network issues by running diagnostic tools. Troubleshoot interface configuration and faults by using ping, traceroute, or packet capture, or by using the CLI terminal.
J-Web Application Package—First Look
Each page of the J-Web interface is divided into panes.
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–Monitor, 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 interface.
The J-Web interface provides CLI tools that enable 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 enables you to click through all of the available CLI statements.
