Using the CLI
Utility describes commands used to manage the switch.
Commands that cause specific actions to be taken immediately by the system
and do not directly affect the system configurations are defined at the top of
the command tree. For example, commands for rebooting the system or for
downloading or backing up the system configuration files are placed at the
top of the hierarchy tree.
Commands that result in configuration changes to the switch are grouped in
a Configuration sub tree.
There are levels beneath the Configuration mode for further grouping of
commands. The system prompt reflects these sub-Configuration modes.
All the parameters are provided with reasonable defaults where possible.
When starting a session, the initial mode is the User EXEC mode. Only a
limited subset of commands is available in this mode. This level is reserved
for tasks that do not change the configuration. To enter the next level, the
Privileged EXEC mode, a password is required.
The Privileged EXEC mode provides access to commands that can not be
executed in the User EXEC mode and permits access to the switch
Configuration mode.
The Global Configuration mode manages switch configuration on a global
level. For specific interface configurations, command modes exist at a sub-
level.
Entering a <
?
> at the system prompt displays a list of commands available
for that particular command mode. A specific command is used to navigate
from one command mode to another. The standard order to access the modes
is as follows: User EXEC mode, Privileged EXEC mode, Global
Configuration mode, and Interface Configuration and other specific
configuration modes.
User EXEC Mode
After logging into the switch, the user is automatically in the User EXEC
command mode unless the user is defined as a privileged user. In general, the
User EXEC commands allow the user to perform basic tests, and list system
information.
The user-level prompt consists of the switch host name followed by the angle
bracket (>).
