Junos Cli Basics - Juniper J2300 Quick Start Quide

J-series Services Router Quick Start
The first time you connect to a Services Router with the J-Web interface, you bypass
the login page and go directly to the Set Up Quick Configuration page. At subsequent
logins, you go directly to the System Monitor page.
Click Monitor to display information about the system (system serial number, CPU,
and memory usage), interfaces, configured routes, and other Services Router
functions.
Click Configuration to access Quick Configuration wizard" pages for common
configuration tasks such as initial setup, certificate installation, basic routing setup,
and creation of firewall filters and IPSec tunnels. Each new release of the JUNOS
software adds more Quick Configuration features.
For configuration details and tasks not covered by Quick Configuration, you can
access a graphical version of the JUNOS CLI known as the J-Web configuration editor.
Select Configuration>View and Edit Configuration>Edit Configuration to display
a list of configurable features—like the list displayed when you enter
configuration mode.
When you click OK or Apply on J-Web Quick Configuration pages, the configuration
is saved and activated automatically. In contrast, you must click Commit to apply
changes on J-Web configuration editor pages.
For complete information about J-Web configuration features, see the J-series Services
Router Basic LAN and WAN Access Configuration Guide.
