Understanding J-Web Configuration Tools

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

The J-Web interface provides two methods of configuring the switch:

Table 2 gives a comparison of the two methods of configuration.

In addition to configuration, you can use the J-Web interface to perform many monitoring, troubleshooting, and management tasks on the switch.

Table 2: Switching Platform Configuration Interfaces

ToolDescriptionFunctionUse

Configure menu

Web browser pages for setting up the switch quickly and easily without configuring each statement individually.

For example, use the Virtual Chassis Configuration page to configure the virtual chassis parameters on the switch.

Configure basic switch platform services:

  • Interfaces
  • Switching
  • Virtual Chassis
  • Security
  • Services
  • System Properties
  • Routing

Use for basic configuration.

Point & Click editor

Web browser pages divided into panes in which you can do any of the following:

  • Expand the entire configuration hierarchy and click a configuration statement to view or edit. The main pane displays all the options for the statement, with a text box for each option.
  • Paste a complete configuration hierarchy into a scrollable text box, or edit individual lines.
  • Upload or download a complete configuration.
  • Roll back to a previous configuration.
  • Create or delete a rescue configuration.

Configure all switching platform services:

  • System parameters
  • User Accounting and Access
  • Interfaces
  • VLAN properties
  • Virtual Chassis properties
  • Secure Access
  • Services
  • Routing protocols

Use for complete configuration if you are not familiar with the JUNOS CLI or prefer a graphical interface.

CLI editor

Interface in which you do either of the following:

  • Type commands on a line and press Enter to create a hierarchy of configuration statements.
  • Create an ASCII text file that contains the statement hierarchy.
  • Upload a complete configuration, or roll back to a previous configuration.
  • Create or delete a rescue configuration.

Configure all switching platform services:

  • System parameters
  • User Accounting and Access
  • Interfaces
  • VLAN properties
  • Virtual Chassis properties
  • Secure Access
  • Services
  • Routing protocols

Use for complete configuration if you know the JUNOS CLI or prefer a command interface.

Before using the switching platform configuration tools, become familiar with the terms defined in Table 3.

Table 3: Configuration Tools Terms

Term

Definition

candidate configuration

A working copy of the configuration that users can edit without affecting the switching platform until that copy is committed.

configuration group

Group of configuration statements that can be inherited by the rest of the configuration.

commit a configuration

Have the candidate configuration checked for proper syntax, activated, and marked as the current configuration file running on the switching platform.

configuration hierarchy

The JUNOS software configuration consists of a hierarchy of statements. There are two types of statements: container statements, which contain other statements, and leaf statements, which do not contain other statements. All the container and leaf statements together form the configuration hierarchy.

rescue configuration

Configuration that recovers a switching platform from a configuration that denies management access. You set a current committed configuration to be the rescue configuration through the J-Web interface or CLI for emergency use.

roll back a configuration

Return to a previously committed configuration.
