3.2.1 Command mode
The CLI is divided into many different modes. The commands available to you at any
given time depend on the mode that you are currently in. Entering a question mark (?)
at the CLI prompt allows you to obtain a list of commands available for each com-
mand mode.
When you log in to the CLI, you are in user mode. User mode contains only a limited
subset of commands.
To have access to all commands, you must enter enable mode normally by using a
password. From enable mode, you can issue any enable mode command.
You can enter global configuration mode by entering configure terminal command.
Configuration modes allow you to make changes to the running configuration. If you
later save the running configuration to the startup configuration, these changed com-
mands are stored when the software is rebooted. To enter specific configuration
modes, you must start at global configuration mode. From global configuration mode,
you can enter interface configuration mode and a variety of other modes.
Table 3-1 describes how to access and exit various common command modes on
