Using the CLI
247
• running-config — This file refers to the configuration file currently active
in the system. It is possible to copy the running-config image to a backup-
config file or to the startup-config file.
• 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.
• active & backup — These files refer to software images. The active image
will be loaded when the system next reboots. Either the active or backup
can be chosen for the next reboot using the command boot system.
The 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/console port, the out-of-
band interface, or in-band interfaces. Since the console port requires a
physical connection for access, it is used if all else fails. The console port
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 IP address for the
switch. IP addresses are assigned separately for the out-of-band interface
and the in-band ports.
• The CLI is accessible from a secure shell interface.
• The administrator generates keys for SSH locally via the CLI.
