J-Web Package

As an alternative to entering CLI commands, JUNOS supports a J-Web graphical user interface (GUI). The J-Web user interface enables you to monitor, configure, troubleshoot, and manage the router on a client by means of a Web browser with Hypertext Transfer Protocol (HTTP) or HTTP over Secure Sockets Layer (HTTPS) enabled.

The J-Web user interface is preinstalled on J-series Services Routers. It is provided as an optional, licensed software package (jweb package) on M-series and T-series routing platforms. The jweb package is not included in jinstall and jbundle software bundles. It must be installed separately. To install the package on M-series and T-series routing platforms, follow the procedure described in the JUNOS Software Installation and Upgrade Guide.

J-Web supports weak (56-bit) encryption by default. This enables international customers to install J-Web and use HTTPS connections for J-Web access. Domestic customers can also install the jcrypto strong encryption package. This package automatically overrides the weak encryption. For more information about the J-Web GUI, see the J-Web Interface User Guide.

Note: Because the J-Web package is bundled separately from other packages, it is possible to have a version mismatch between J-Web and other JUNOS software packages you have installed. To check for a version mismatch, use the show system alarms CLI command. If the version number does not match exactly, a system alarm appears. For example, if you install the 7.4R1.2 jroute package and the 7.4R1.1 jweb package, an alarm is activated. For more information on the show system alarms command, see the JUNOS System Basics and Services Command Reference.
