Chapter 2 Understanding the User Interface
Accessing Each Command Mode
You can enter commands in uppercase, lowercase, or a mix of both. Only passwords are case sensitive.
You can abbreviate commands and keywords to a minimum unique string of characters. For example,
you can abbreviate the show command to sh. After entering the command line at the system prompt,
press the Return key to execute the command.
Almost every configuration command has a no form. In general, use the no form to disable a feature or
function. Use the command without the no keyword to reenable a disabled feature or enable a feature
disabled by default.
Note Refer to the ATM Switch Router Command Reference publication for the complete syntax of commands
specific to the ATM switch router and a description of the function of the no form of a command. Refer
to the Configuration Fundamentals Command Reference publication for the complete syntax of other
IOS commands.
Accessing Each Command Mode

Table 2-2 list the command modes, access to each mode, the prompt you see while in that mode, the main

default ATM switch router name “Switch.” Table 2-1 and Table 2-2 might not include all of the possible
