Using the Command-Line Interface
12
ProSafe M4100 and M7100 Managed Switches
Note: In the CLI, loopback and tunnel interfaces do not use the slot/port
format. To specify a loopback interface, you use the loopback ID. To
specify a tunnel interface, you use the tunnel ID.
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
address 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).
• Stacking
Not 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
