7. CLI Guide
7.1. Introduction
The root user can access the Linux console command line interface (CLI) of the Pro Series via the
serial console or TELENT/SSH. In the CLI, the user can perform standard Linux commands to view
the status of the Pro Series, edit the configuration, apply configuration changes.
7.2. Flash Partition
The Pro Series internal flash is partitioned as shown in the table below. The user can access files at
/var directory at his own risk. Simply accessing these files will not affect the Pro 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 Pro Series. This will result in the changes
being kept after the reboot sequence. Invalid configuration changes can affect the Pro Series behavior.
At worst, it may cause the Pro Series to become inoperable.
