Configuration Tools Overview

The J-Web interface provides a Quick Configuration tool for basic configuration
and a configuration editor for complete configuration. You can also use the JUNOS
CLI configuration mode as a configuration editor to create and modify a complete
configuration hierarchy. For a comparison of configuration interfaces, see Table 35.

Editing and Committing a Configuration

When you edit a configuration, you work in a copy of the current configuration
to create a candidate configuration. The changes you make to the candidate
configuration are visible through the user interface immediately, but do not
take effect on the Services Router until you commit the changes. When you
commit the configuration, the candidate file is checked for proper syntax,
activated, and marked as the current, operational software configuration file. If
multiple users are editing the configuration when you commit the candidate
configuration, all changes made by all the users take effect.
If you are editing the configuration with the CLI, you can edit an exclusive
or private candidate configuration. For more information, see "Entering
and Exiting Configuration Mode" on page 146.
When you commit a configuration, the Services Router saves the current operational
version and the previous 49 versions of committed configurations. The most
recently committed configuration is version 0 (the current operational version), and
the oldest saved configuration is version 49. You can roll back the configuration
to any saved version. Version 0 is stored in the file

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.
Configuration that recovers a Services Router from a configuration that denies management
access. You set a current committed configuration through the J-Web interface or CLI for
emergency use. To load and commit the rescue configuration, you press and release the
CONFIG button.
