Chapter 2 Command Line Interface
Authorization and Command Levels (Hierarchy)
CLI Command Hierarchy
The set of all CLI commands is grouped in hierarchical order, according to the type of the commands.
The first two levels in the hierarchy are the User Exec and Privileged Exec modes. These are
non-configuration modes in which the set of available commands enables the monitoring of the SCE
platform, file system operations, and other operations that cannot alter the configuration of the SCE
platform.
The next levels in the hierarchy are the Global and Interface configuration modes, which hold a set of
commands that control the global configuration of the SCE platform and its interfaces. Any of the
parameters set by the commands in these modes should be saved in the startup configuration, such that
in the case of a reboot, the SCE platform restores the saved configuration.
The following table shows the available CLI modes.
When you login to the system, you have the User authorization level and enter User Exec mode.
Changing the authorization level to Viewer does not change the mode. Changing the authorization level
to Admin automatically moves you to Privileged Exec mode. To move to any of the configuration modes,
you must enter commands specific to that mode.
A telnet session begins with a request for password, and will not continue until the proper user password
is supplied. This enhances the security of the system by not revealing its identity to unauthorized people.
The list of available commands in each mode can be viewed using the question mark ‘?’ at the end of the
prompt.
