J2320, J2350, J4350, and J6350 Services Router Getting Started Guide

■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 routers.

■Managing—Manage log, temporary, and core (crash) files and schedule reboots on the J-series routers. On J-series routers, 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 router. You can configure files to log system log messages and also assign attributes, such as severity levels, to messages.

■Configuring and monitoring alarms—On J-series routers only, monitor and diagnose the router 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.

Interface” on page 81.

CLI Overview

The CLI is a straightforward command interface in which you type commands on a line and press Enter to execute them. The CLI provides command help, command completion, and Emacs-style keyboard sequences for moving around on the command line and scrolling through a buffer of recently executed commands.

The CLI has two modes:

■Operational mode—Complete set of commands to control the CLI environment, monitor and troubleshoot network connectivity, manage the Services Router, and enter configuration mode.

■Configuration mode—Complete set of commands to configure the Services Router. This guide refers to configuration mode as the CLI configuration editor.

For more information about the CLI, see “Using the Command-Line

Interface” on page 89.

Before You Begin

Before you start the user interface, you must perform the initial Services Router configuration described in “Establishing Basic Connectivity” on page 129. After the initial configuration, you use your username and password, and the hostname or IP address of the router, to start the user interface.
