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.
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.

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) |

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. |
|
|
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.
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 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.
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.

mtu
Use the mtu command to set the maximum transmission unit (MTU) size, in bytes, for frames that ingress or egress the interface. You can use the mtu command to configure jumbo frame support for physical and port-channel (LAG) interfaces. For the standard 7000 series implementation, the MTU size is a valid integer between 1522–9216 for tagged packets and a valid integer between 1518–9216 for untagged packets.
Note: To receive and process packets, the Ethernet MTU must include any extra bytes that Layer-2 headers might require. To configure the IP MTU size, which is the maximum size of the IP packet (IP Header + IP payload), see ip mtu on page 233.

show port advertise
Use this command to display the local administrative link advertisement configuration, local operational link advertisement, and the link partner advertisement for an interface. It also displays priority Resolution for speed and duplex as per 802.3 Annex 28B.3. It displays the autonegotiation state, Phy Master/Slave Clock configuration, and Link state of the port.
If the link is down, the Clock is displayed as No Link, and a dash is displayed against the Oper Peer advertisement, and Priority Resolution. If autonegotiation is disabled, the admin Local Link advertisement, operational local link advertisement, operational peer advertisement, and Priority resolution fields are not displayed.
If this command is executed without the optional slot/port parameter, it displays the autonegotiation state and operational Local link advertisement for all the ports. Operational link advertisement will display speed only if it is supported by both local as well as link partner. If autonegotiation is disabled, operational local link advertisement is not displayed.

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.
