Command Line Interface Reference for the ProSafe 7300S Series Layer-3 Stackable Switches, 2.3.4 Using the "No" Form of a Command The no keyword is a specific form of an existing command and does not represent a new or distinct command. Almost every configuration command has a no form. In general, use the no form to reverse the action of a command or reset a value back to the default. For example, the no shutdown configuration command reverses the shutdown of an interface. Use the command without the keyword no to re-enable a disabled feature or to enable a feature that is disabled by default. Only the configuration commands are available in the no form. 2.3.5 Command Modes The CLI groups commands into modes according to the command function. Each of the command modes supports specific 7300S Series Stackable Switch software commands. The commands in one mode are not available until you switch to that particular mode, with the exception of the User EXEC mode commands. You can execute the User EXEC mode commands in the Privileged EXEC mode. The command prompt changes in each command mode to help you identify the current mode. Table 2-5 describes the command modes and the prompts visible in that mode. Table 2-5. CLI Command Modes Command Mode Prompt Mode Description User EXEC Switch> Privileged EXEC Switch# Global Config Switch (Config)# VLAN Config Switch (Vlan)# Contains a limited set of commands to view basic system information. Allows you to issue any EXEC command, enter the VLAN mode, or enter the Global Configuration mode. Groups general setup commands and permits you to make modifications to the running configuration.

Command Line Interface Reference for the ProSafe 7300S Series Layer-3 Stackable Switches,
2-6
Overview
v3.0, January 2008
2.3.4
Using the “No” Form of a Command
The
no
keyword is a specific form of an existing command and does not represent a new
or distinct command. Almost every configuration command has a
no
form. In general, use
the
no
form to reverse the action of a command or reset a value back to the default. For
example, the
no shutdown
configuration command reverses the shutdown of an interface.
Use the command without the keyword
no
to re-enable a disabled feature or to enable a
feature that is disabled by default.
Only the configuration commands are available in the
no
form.
2.3.5
Command Modes
The CLI groups commands into modes according to the command function. Each of the
command modes supports specific 7300S Series Stackable Switch software commands.
The commands in one mode are not available until you switch to that particular mode,
with the exception of the User EXEC mode commands. You can execute the User EXEC
mode commands in the Privileged EXEC mode.
The command prompt changes in each command mode to help you identify the current
mode. Table 2-5 describes the command modes and the prompts visible in that mode.
