8. CLI Guide

8.1. Introduction

The Super Series root or System Administrator (only admin account is added for this group user by factory default) can access the Linux console command line interface (CLI) of the Super Series via the serial console or TELENT/SSH. In the CLI, the authorized user can perform standard Linux commands to view the status of the Super Series, edit the configuration, apply configuration changes, define user scripts and transmit files between the Super Series and remote hosts.

The Super Series provides 1024 KB user space mounted in /usr2 for read/write capabilities in its internal flash memory. Using the user space, the user can create his own scripts or executable binaries to customize the Super Series.

A root user will always have access to the CLI through the serial console on the Super Series back panel or by using a Telnet client from their workstation.

A System Administrator cannot have access to the CLI.

He can only access console configuration menu or Web UI.

8.2. Flash Partition

The Super Series internal flash is partitioned as shown in the table below. The users can freely access the Mtdblock5 which is mounted on /usr2 for their own needs. The user can also access files at

/etc

, /var, and /temp at their own risk. Simply accessing these files will not affect the Super Series after rebooting. However, if the user invokes the command saveconf, the changes in the configuration file will be committed to the internal flash memory area of the Super Series. This will result in the changes being kept after the reboot sequence. Invalid configuration changes can affect the Super Series behavior. At worst, it may cause the Super Series to be inoperable.
