J-Web Overview

The J-Web interface allows you to monitor, configure, troubleshoot, and manage your device by means of a Web browser enabled with Hypertext Transfer Protocol (HTTP) or HTTP over Secure Sockets Layer (HTTPS). J-Web provides access to all the configuration statements supported by the device, so you can fully configure it without using the CLI editor.

You can perform the following tasks with the J-Web interface:

• Monitoring—Display the current configuration and information about the system, interfaces, chassis, routing protocols, routing tables, routing policy filters, and other features.
• Configuring—View the current configurations at a glance, configure the device, and manage configuration files. The J-Web interface provides the following different configuration methods:
  • Configure the device quickly and easily without configuring each statement individually.
  • Edit a graphical version of the JUNOS software with enhanced services CLI configuration statements and hierarchy.
  • Edit the configuration in a text file.
  • Upload a configuration file.

  The J-Web interface also allows you to manage configuration history and set a rescue configuration.

• Diagnosing—Diagnose routing problems by running the ping or traceroute diagnostic tool. The diagnostic tools also allow you to capture and analyze control traffic on the devices.
• Managing—Manage log, temporary, and core (crash) files and schedule reboots on your devices. You can also manage software packages and licenses and copy a snapshot of the system software to a backup device.
• Configuring and monitoring events—Filter and view system log messages that record events occurring on the device. You can configure files to log system log messages and also assign attributes, such as severity levels, to messages.
• Configuring and monitoring alarms—Monitor and diagnose the device by monitoring active alarms that alert you to the conditions on a network interface. You can also set the conditions that trigger alarms on an interface.
