Connection Using SSH

An alternative to using the local console port for CLI access is to connect via a physical Ethernet
interface and using a Secure Shell (SSH) client on the management workstation to issue CLI
commands. This is discussed further in

Section 4.1, “Management Workstation Connection”

Note: Setting a local console password is recommended

A local console password need not be set. However, if it is not, anyone with physical
access to the local console will have full administrator rights.

Unless the hardware is placed in a secure area, it is therefore recommended to set a local
console password. This is done by entering the console

boot menu

at system startup by

pressing any console key before cOS Core has fully started. The boot menu and its
options is discussed further in the separate

cOS Core Administrators Guide
