1.0 Command Structure
The Command Line Interface (CLI) syntax, conventions and terminology are described in this
section. Each CLI command referenced in this document is illustrated using the structure
outlined below.
1.1 Format
Some commands, such as clear vlan, do not require parameters. Other commands, such as
network parms, have parameters for which you must supply a value. Parameters are
positional — you must type the values in the correct order. Optional parameters will follow
required parameters. For example:
Example 1
network parms <ipaddr> <netmask> [gateway]
network parms is the command name.
<ipaddr> <netmask> are the required values for the command.
[gateway] is the optional value for the command.
Example 2
snmp-server location <loc>
snmp-server location is the command name.
<loc> is the required parameter for the command.
Example 3
clear vlan
clear vlan is the command name.
1.1.1 Command
The following conventions apply to the command name:
zThe command name is displayed in this document in bold font and must be typed exactly as shown.
zOnce you have entered enough letters of a command name to uniquely identify the command,
pressing the <Space bar> or <Tab key> will cause the system to complete the word.
zEntering Ctrl-Z will return you to the root level command prompt.
1.1.2 Parameters
Parameters are order dependent.
Parameters are displayed in this document in italic font, which must be replaced with a name or
number.

Command Structure 5
© 2001- 2006 Hirschmann Automation and Control GmbH. All Rights Reserved.
To use spaces as part of a name parameter, enclose it in double quotes. For example, the
expression "System Name with Spaces" forces the system to accept the spaces.
Parameters may be mandatory values, optional values, choices, or a combination.
<parameter>. The <> angle brackets indicate that a value must be entered in place
of the brackets and text inside them.
[parameter]. The [] square brackets indicate an optional parameter that may be
entered in place of the brackets and text inside them.
choice1 | choice2. Vertical bars ‘|’ separate alternative, mutually exclusive, elements.
The {} curly braces indicate that a parameter must be chosen from the list of choices.
Braces within square brackets [{}] indicate a required choice within an optional element.
1.1.3 Values
Ipaddr This parameter is a valid IP address. Presently the IP address can be entered in
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, decimal, hexidecimal and octal formats are supported
through the following input formats (where n is any valid hexidecimal, octal or deci-
mal number):
0xn (CLI assumes hexidecimal format)
0n (CLI assumes octal format with leading zeros)
n (CLI assumes decimal format)
Macaddr The MAC address format is six hexadecimal numbers separated by colons, for
example 00:06:29:32:81:40.
Areaid Area IDs may be entered in dotted-decimal notation (for example, 0.0.0.1).
An area ID of 0.0.0.0 is reserved for the backbone. Area IDs have the same
form as IP addresses, but are distinct from IP addresses. The IP network num-
ber of the sub-netted network may be used for the area ID.
Routerid The value of <router id> must be entered in 4-digit dotted-decimal notation
(for example, 0.0.0.1). A router ID of 0.0.0.0 is invalid.
Interface Valid slot and port number separated by forward slashes. For example, 1/1
represents slot number 1 and port number 1. See “Unit-Slot-Port Naming
Convention” on page 7.
Logical Interface Logical slot and port number. This is applicable in the case of a port-
channel (LAG). The operator can use the logical slot/port to configure the
port-channel. See “Unit-Slot-Port Naming Convention” on page 7.
Character strings Use double quotation marks to identify character strings, for example,
“System Name with Spaces”. An empty string (“”) is not valid.

Command Structure 6

1.1.4 Conventions
Network addresses are used to define a link to a remote host, workstation or network.
Network addresses are shown using the following syntax:
Double quotation marks such as "System Name with Spaces" set off user defined
strings. If the operator wishes to use spaces as part of a name parameter then it must be
enclosed in double quotation marks.
Empty strings (““) are not valid user defined strings.
Command completion finishes spelling the command when enough letters of a com-
mand are typed to uniquely identify the command word. The command may be exe-
cuted by typing <enter> (command abbreviation) or the command word may be
completed by typing the <tab> or <space bar> (command completion).
The value 'Err' designates that the requested value was not internally accessible. This
should never happen and indicates that there is a case in the software that is not han-
dled correctly.
The value of '-----' designates that the value is unknown.
1.1.5 Annotations
The CLI allows the user to type single-line annotations at the command prompt for use when
writing test or configuration scripts and for better readability. The exclamation point (‘!’)
character flags the beginning of a comment. The comment flag character can begin a word
anywhere on the command line and all input following this character is ignored. Any
command line that begins with the character ‘!’ is recognized as a comment line and ignored
by the parser.
Some examples are provided below:
! Script file for setting the CLI prompt
set prompt example-switch
! End of the script file
1.1.6 Special Characters
Certain special key combinations speed up use of the CLI. They are listed in this section. Also,
help is available for the CLI by typing HELP:
BS delete previous character
Ctrl-A go to beginning of line

Ctrl-T transpose previous character
Ctrl-P go to previous line in history buffer
Ctrl-N go to next line in history buffer
Ctrl-Z return to root command prompt
Tab, <SPACE> command-line completion
Exit go to next lower command prompt
1.1.7 Unit-Slot-Port Naming Convention
Switch software references physical entities such as cards and ports using a Slot/Port naming
convention. This convention is also used to identify certain logical entities such as Link Aggregation
(LAG) 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 ports it also identifies the type of interface or port.
Physical slot numbers
Physical slot numbers begin with one, and are allocated up to the maximum number of physi-
cal slots
Logical slot numbers
Logical slots immediately follow physical slots and identify LAG or router interfaces. For
LAG the slot number 8 is used. For VLAN interfaces the slot number 9 is used.
The port identifies the specific physical port or logical interface being managed on a given slot.
Physical Ports
The physical ports for each slot are numbered sequentially starting from one.
Logical Interfaces
There are two types of logical interfaces: LAG and VLAN routing interfaces.
LAG interfaces are only used for bridging functions. Each LAG interface consists of a set
of up to eight physical ports identified by their own Slot/Port.
VLAN routing interfaces are only used for routing functions.

2.0 Quick Start up
The CLI Quick Start up details procedures to quickly become acquainted with the switch software.
2.1 Quick Starting the Networking Device
1. Read the device Installation Guide for the connectivity procedure. In-band connectivity allows
access to the switch software locally or from a remote workstation. The device must be configured
with IP information (IP address, subnet mask, and default gateway).
2. Turn the Power ON.
3. Allow the device to load the software until the login prompt appears. The device initial state is
called the default mode.
4. When the prompt asks for operator login, execute the following steps:
Type the word admin in the login area. Since a number of the Quick Setup commands
require administrator account rights, Hirschmann suggests logging into an administrator
account.
Enter the password private. There is the password private in the default mode.
Press the enter key two times.
The CLI User EXEC prompt will be displayed.
Use “enable” to networking device to the Privileged EXEC mode from User EXEC.
Use “configure” to switch to the Global Config mode from Privileged EXEC.
Use “exit” to return to the previous mode.

3.2 Mode-based Command Hierarchy
The CLI is divided into various modes. The Commands in one mode are not available until the operator
switches to that particular mode, with the exception of the User EXEC mode commands. The User
EXEC mode commands may also be executed in the Privileged EXEC mode.
The commands available to the operator at any point in time depend upon the mode. Entering a question
mark (?) at the CLI prompt, displays a list of the available commands and descriptions of the
commands.
The name „switch“ in the following command prompts is standing in for the name of the device. The
CLI provides the following modes:
User EXEC Mode
When the operator logs into the CLI, the User EXEC mode is the initial mode. The User EXEC
mode contains a limited set of commands. The command prompt shown at this level is:
Command Prompt: Switch>
Privileged EXEC Mode
To have access to the full suite of commands, the operator must enter the Privileged EXEC
mode. Privileged users authenticated by login are able to enter the Privileged EXEC mode.
From Privileged EXEC mode, the operator can issue any EXEC command, enter the VLAN
mode or enter the Global Configuration mode. The command prompt shown at this level is:
Command Prompt: Switch#
VLAN Mode
This mode groups all the commands pertaining to VLANs. The command prompt shown at
this level is:
Command Prompt: Switch(Vlan)#
Global Config Mode
This mode permits the operator to make modifications to the running configuration. General
setup commands are grouped in this mode. From the Global Configuration mode, the operator
can enter the System Configuration mode, the Physical Port Configuration mode, the Interface
Configuration mode, or the Protocol Specific modes specified below. The command prompt at
this level is:
Command Prompt: Switch(Config)#
From the Global Config mode, the operator may enter the following configuration modes:
Interface Config Mode
Many features are enabled for a particular interface. The Interface commands enable or modify
the operation of an interface.
In this mode, a physical port is set up for a specific logical connection operation. The Interface
Config mode provides access to the router interface configuration commands. The command
prompt at this level is:
Command Prompt: Switch(Interface <slot/port>)#
The resulting prompt for the interface configuration command entered in the Global Configu-
ration mode is shown below:
Switch(Config)# interface 2/1
Switch(Interface 2/1)#

Mode-based Command Line Interface 16
© 2001- 2006 Hirschmann Automation and Control GmbH. All Rights Reserved.
Line Config Mode
This mode allows the operator to configure the console interface. The operator may configure
the interface from the directly connected console or the virtual terminal used with Telnet. The
command prompt at this level is:
Command Prompt: Switch(line)#
Router OSPF Config Mode:
In this mode, the operator is allowed to access the router OSPF configuration commands. The
command prompt at this level is:
Switch(Config)# router ospf
Command Prompt: Switch(Config router)#
Router RIP Config Mode:
In this mode, the operator is allowed to access the router RIP configuration commands. The
command prompt at this level is:
Switch(Config)# router rip
Command Prompt: Switch(Config router)#
MAC Access-List Config Mode
Use the MAC Access-List Config mode to create a MAC Access-List and to enter the mode
containing Mac Access-List configuration commands.
Switch(Config)# mac-access-list extended <name>
Command Prompt: Switch(Config mac-access-list)#
3.3 “No” Form of a Command
“No” is a specific form of an existing command and does not represent a new or distinct command.
Only the configuration commands are available in the “no” form.
3.3.1 Support for “No” Form
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.

Routing Commands 17
© 2001- 2006 Hirschmann Automation and Control GmbH. All Rights Reserved.
4.0 Routing Commands
This chapter provides a detailed explanation of the Routing commands.
4.1 Address Resolution Protocol (ARP) Commands
This chapter provides a detailed explanation of the ARP commands. The commands are divided by
functionality into the following different groups:
zShow commands are used to display switch settings, statistics and other information.
zConfiguration Commands are used to configure features and options of the switch. For every con-
figuration command there is a show command that will display the configuration setting.
zCopy commands are used to transfer configuration and informational files to and from the switch.
4.1.1 arp
This command creates an ARP entry. The value for <ipaddress> is the IP address of a device on a
subnet attached to an existing routing interface. <macaddr> is a unicast MAC address for that device.
The format is 6 two-digit hexadecimal numbers that are separated by colons, for example
00:06:29:32:81:40.
Format arp <ipaddress> <macaddr>
Mode Global Config
4.1.1.1 no arp
This command deletes an ARP entry. The value for <arpentry> is the IP address of the interface. The
value for <ipaddress> is the IP address of a device on a subnet attached to an existing routing
interface. <macaddr> is a unicast MAC address for that device.
Format no arp <ipaddress> <macaddr>
Mode Global Config
4.1.2 ip proxy-arp
This command enables proxy ARP on a router interface.
Without proxy ARP, a device only responds to an ARP request if the target IP address is an address
configured on the interface where the ARP request arrived. With proxy ARP, the device may also
respond if the target IP address is reachable. The device only responds if all next hops in its route to the
destination are through interfaces other than the interface that received the ARP request.
Default enabled
Format ip proxy-arp
Mode Interface Config
4.1.2.1 no ip proxy-arp
This command disables proxy ARP on a router interface.
Format no ip proxy-arp
Mode Interface Config
