Command Syntax

A command is one or more words that might be followed by one or more parameters. Parameters can be required or optional values.

Some commands, such as show network or clear vlan, do not require parameters. Other commands, such as network parms, require that you supply a value after the command. You must type the parameter values in a specific order, and optional parameters follow required parameters. The following example describes the network parms command syntax:

Format network parms <ipaddr> <netmask> [gateway]

•network parms is the command name.

•<ipaddr> and <netmask> are parameters and represent required values that you must enter after you type the command keywords.

•[gateway] is an optional parameter, so you are not required to enter a value in place of the parameter.

The New Template User Manual lists each command by the command name and provides a brief description of the command. Each command reference also contains the following information:

•Format shows the command keywords and the required and optional parameters.

•Mode identifies the command mode you must be in to access the command.

•Default shows the default value, if any, of a configurable setting on the device.

The show commands also contain a description of the information that the command shows.

Command Conventions

In this document, the command name is in bold font. Parameters are in italic font. You must replace the parameter name with an appropriate value, which might be a name or number. Parameters are order-dependent.

The parameters for a command might include mandatory values, optional values, or keyword choices. Table 1 describes the conventions this document uses to distinguish between value types.

Table 1. Parameter Conventions

Symbol	Example	Description
<> angle brackets	<value>	Indicates that you must enter a value in place of the
		brackets and text inside them.
[] square brackets	[value]	Indicates an optional parameter that you can enter in
		place of the brackets and text inside them.
{} curly braces	{choice1 |	Indicates that you must select a parameter from the list of
	choice2}	choices.
| Vertical bars	choice1 | choice2	Separates the mutually exclusive choices.
[{}] Braces within	[{choice1 |	Indicates a choice within an optional element.
square brackets	choice2}]

Common Parameter Values

Parameter values might be names (strings) or numbers. To use spaces as part of a name parameter, enclose the name value in double quotes. For example, the expression “System Name with Spaces” forces the system to accept the spaces. Empty strings (““) are not valid user-defined strings. Table 2 describes common parameter values and value formatting.

Table 2. Parameter Descriptions

Parameter	Description
ipaddr	This parameter is a valid IP address. You can enter the IP address in the following formats:
	a (32 bits)
	a.b (8.24 bits)
	a.b.c (8.8.16 bits)
	a.b.c.d (8.8.8.8)
	In addition to these formats, the CLI accepts decimal, hexadecimal, and octal formats
	through the following input formats (where n is any valid hexadecimal, octal, or decimal
	number):
	0xn (CLI assumes hexadecimal format)
	0n (CLI assumes octal format with leading zeros)
	n (CLI assumes decimal format)
ipv6-address	FE80:0000:0000:0000:020F:24FF:FEBF:DBCB, or
	FE80:0:0:0:20F:24FF:FEBF:DBCB, or
	FE80::20F24FF:FEBF:DBCB, or
	FE80:0:0:0:20F:24FF:128:141:49:32
	For more information, refer to RFC 3513.
Interface or	Valid slot and port number separated by forward slashes. For example, 0/1 represents slot
slot/port	number 0 and port number 1.

ProSafe M4100 and M7100 Managed Switches

Table 2. Parameter Descriptions (Continued)

Parameter	Description
Logical Interface	Represents a logical slot and port number. This is applicable in the case of a port-channel
	(LAG). You can use the logical slot/port to configure the port-channel.
Character strings	Use double quotation marks to identify character strings, for example, “System Name with
	Spaces”. An empty string (“”) is not valid.

Slot/Port Naming Convention

Managed switch software references physical entities such as cards and ports by using a slot/port naming convention. The software also uses this convention to identify certain logical entities, such as Port-Channel interfaces.

The slot number has two uses. In the case of physical ports, it identifies the card containing the ports. In the case of logical and CPU ports it also identifies the type of interface or port.

Table 3. Type of Slots

Slot Type	Description
Physical slot numbers	Physical slot numbers begin with zero, and are allocated up to the maximum
	number of physical slots.
Logical slot numbers	Logical slots immediately follow physical slots and identify port-channel (LAG) or
	router interfaces.
CPU slot numbers	The CPU slots immediately follow the logical slots.

The port identifies the specific physical port or logical interface being managed on a given slot.

Table 4. Type of Ports

Port Type	Description
Physical Ports	The physical ports for each slot are numbered sequentially starting from zero.
Logical Interfaces	Port-channel or link aggregation group (LAG) interfaces are logical interfaces that
	are only used for bridging functions.
	VLAN routing interfaces are only used for routing functions.
	Loopback interfaces are logical interfaces that are always up.
	Tunnel interfaces are logical point-to-point links that carry encapsulated packets.
CPU ports	CPU ports are handled by the driver as one or more physical entities located on
	physical slots.

Using the Command-Line Interface

11

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

Using the Command-Line Interface

12

ProSafe M4100 and M7100 Managed Switches

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.

Note: The command modes available on your switch depend on the software modules that are installed. For example, a switch that does not support BGPv4 does not have the Router BGPv4 Command Mode.

Loopback Interface Commands

The commands in this section describe how to create, delete, and manage loopback interfaces. A loopback interface is always expected to be up. This interface can provide the source address for sent packets and can receive both local and remote packets. The loopback interface is typically used by routing protocols.

To assign an IP address to the loopback interface, see ip address on page 228. To assign an IPv6 address to the loopback interface, see ipv6 address on page 359.

interface loopback

Use this command to enter the Interface Config mode for a loopback interface. The range of the loopback ID is 0–7.

Format	interface loopback <loopback-id>
Mode	Global Config

no interface loopback

This command removes the loopback interface and associated configuration parameters for the specified loopback interface.

Format	no interface loopback <loopback-id>
Mode	Global Config

show interface loopback

This command displays information about configured loopback interfaces.

Format	show interface loopback [<loopback-id>]
Mode	Privileged EXEC

If you do not specify a loopback ID, the following information appears for each loopback interface on the system:

	Term	Definition
	Loopback ID	The loopback ID associated with the rest of the information in the row.
	Interface	The interface name.
	IP Address	The IPv4 address of the interface.
	Received	The number of packets received on this interface.
	Packets
	Sent Packets	The number of packets transmitted from this interface.
	IPv6 Address	The IPv6 address of this interface.

If you specify a loopback ID, the following information appears:

	Term	Definition
	Interface Link	Shows whether the link is up or down.
	Status
	IP Address	The IPv4 address of the interface.
	IPv6 is enabled	Shows whether IPv6 is enabled on the interface.
	(disabled)

Spanning Tree Protocol (STP) Commands

This section describes the commands you use to configure Spanning Tree Protocol (STP). STP helps prevent network loops, duplicate messages, and network instability.

spanning-tree

This command sets the spanning-tree operational mode to enabled.

Default	enabled
Format	spanning-tree
Mode	Global Config

no spanning-tree

This command sets the spanning-tree operational mode to disabled. While disabled, the spanning-tree configuration is retained and can be changed, but is not activated.

Format	no spanning-tree
Mode	Global Config

spanning-tree auto-edge

This command enables auto-edge on the interface or range of interfaces. When enabled, the interface becomes an edge port if it does not see BPDUs for edge delay time.

Default	enabled
Format	spanning-tree auto-edge
Mode	Interface Config

no spanning-tree auto-edge

This command disables auto-edge on the interface or range of interfaces.

Format	no spanning-tree auto-edge
Mode	Interface Config

spanning-tree bpdufilter

Use this command to enable BPDU Filter on an interface or range of interfaces.

Default	disabled
Format	spanning-tree bpdufilter
Mode	Interface Config
