Using a Command’s “No” Form
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 reenable a disabled feature or to enable a feature that is disabled by
default. Only the configuration commands are available in the no form.
Managed Switch Modules
Managed switch software consists of flexible modules that can be applied in various combinations
to develop advanced Layer 2/3/4+ products. The commands and command modes available on
your switch depend on the installed modules. Additionally, for some show commands, the output
fields might change based on the modules included in the software.
The software suite includes the following modules:
• Switching (Layer 2)
•
Routing (Layer 3)
•
IPv6—IPv6 routing
•
Multicast
•
Quality of Service
•
Management (CLI, web UI, and SNMP)
•
IPv6 Management—Allows management of the device through an IPv6 through an IPv6
addr
ess without requiring the IPv6 Routing package in the system. The management address
can be associated with the network port (front-panel switch ports) and a routine interface
(port or VLAN).
• S

No
t all modules are available for all platforms or software releases.
Command Modes
The CLI groups commands into modes according to the command function. Each of the command
modes supports specific software commands. The commands in one mode are not available until
you switch to that particular mode, except for 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 5 describes the command modes and the prompts visible in that mode.
