• startup-config - This file refers to the special configuration image stored in flash memory which is loaded when the system next reboots. The user may copy a particular configuration file (remote or local) to this special file name and reboot the system to force it to use a particular configuration. • image1 & image2 - These files refer to software images. One of these will be loaded when the system next reboots. Either image1 or image2 can be chosen for the next reboot using the command boot system. CLI prevents the user from accidentally copying a configuration image onto a software image and vice versa. Management Interface Security This section describes the minimum set of management interface security measures implemented by the CLI. Management interface security consists of user account management, user access control and remote network/host access controls. CLI through Telnet, SSH, Serial Interfaces The CLI is accessible through a local serial interface, a remote telnet, or secure shell sessions. Since the serial interface requires a physical connection for access, it is used if all else fails. The serial interface is the only interface from which the user may access the Easy Setup Wizard. It is the only interface that the user can access if the remote authentication servers are down and the user has not configured the system to revert to local managed accounts. The following rules and specifications apply to these interfaces: • The CLI is accessible from remote telnet through the management IP address for the switch. • The CLI is accessible from a secure shell interface. • The CLI generates keys for SSH locally. • The serial session defaults to 9600 baud rate, eight data bits, non-parity and one stop bit. User Accounts Management The CLI provides authentication for users either through remote authentication servers supporting TACACS+ or Radius or through a set of locally managed user accounts. The setup wizard asks the user to create the initial administrator account and password at the time the system is booted. The following rules and specifications apply: • The user may create as many a five local user accounts. • User accounts have an access level, a user name, and a user password. • The user is able to delete the user accounts but the user will not be able to delete the last level 15 account. 129
