Switch Management Overview
This chapter gives an overview of switch management, including the methods you can use to
manage your NETGEAR NETGEAR 7200 Series Layer 2 Managed Switch.
• Management Access Overview
• SNMP Access
• Protocols
Scope
The NETGEAR 7200 Series Layer 2 Managed Switch software has two purposes:
• Assist attached hardware in switching frames, based on Layer 2 or 3 information contained in
the frames.
• Provide a complete switch management portfolio for the network administrator.
Switch Management Overview
Fast Ethernet (FEN) and Gigabit Ethernet (GEN) switching continues to evolve from high-end
backbone applications to desktop switching applications. The price of the technology continues to
decline, while performance and feature sets continue to improve. Devices that are capable of
switching Layers 2, 3, and 4 are increasingly in demand. The NETGEAR 7200 Series Layer 2
Managed Switch provides a flexible solution to these ever-increasing needs.
The NETGEAR 7200 Series Layer 2 Managed Switch provides the network administrator with a
set of comprehensive management functions for managing both the 7200 and the network. The
network administrator has a choice of three easy-to-use management methods:
• Web-based
• VT100 interface
Note: The maximum number of configuration file command lines is 2000 .
Switch Management Overview 2-1

Page 24
User Manual for the NETGEAR 7200 Series Layer 2 Managed Switch Software
• Simple Network Protocol Management (SNMP)
Each management method enables the network administrator to configure, manage, and control
the managed switch locally or remotely using in-band or out-of-band mechanisms. Management is
standards-based, with configuration parameters and a private MIB providing control for functions
not completely specified in the MIBs.

Administration Console Telnet Interface
The administration console is an internal, character-oriented, VT-100/ANSI menu-driven user
interface for performing management activities. Using this method, you can view the
administration console from a terminal, PC, Apple Macintosh, or UNIX workstation connected to
the switch’s console port. Figure 3-1 shows an example of this management method.
Figure 3-1: Administration Console Management Method
Set Up Your Switch Using Direct Console Access
The direct access management method is required when you initially set up your switch.
Thereafter, the convenience and additional features of the Web management access method make
it the best method to manage the switch. See “W eb Based Management Overview” on page 4-1 for
more information.
Direct access to the switch console is achiev ed by connecting the switch’s console port to a
VT-100 or compatible terminal or to a PC, Apple Macintosh, or UNIX workstation equipped with
a terminal-emulation program. This connection is made using the null-modem cable supplied with
the switch.

Web-Based Management Interface
Your NETGEAR 7200 Series Layer 2 Managed Switch provides a built-in browser interface that
lets you configure and manage it remotely using a standard Web browser such as Microsoft
Internet Explorer 5.0 or later or Netscape Navigator 6.0 or later.
This interface also allows for system monitoring and management of the switch. The ‘help’ page
covers many of the basic functions and features of the switch and it’s web interface.
When you configure the switch for the first time from the console, you can assign an IP address
and subnet mask to the switch. Thereafter, you can access the switch’ s Web interface directly using
your W eb browser by entering the switch’s IP address into the address bar. In this way, you can use
your Web browser to manage the switch from a central location, just as if you were directly
connected to the switch’s console port. Figu re 4-1 shows this management method.
Figure 4-1: Web Management Method
Web Based Management Overview
The menu options available are: System Management, Switch, Routing, Traffic Management, and
Smart Wizard. There is a help menu in the top of right side of screen; you can click the ‘help’ or

Page 34
User Manual for the NETGEAR 7200 Series Layer 2 Managed Switch Software
Parameters
Parameters are order dependent.
The text in bold italics should be replaced with a name or number. To use spaces as part of a name
parameter, enclose it in double quotes like this: “System Name with Spaces”.
Parameters may be mandatory values, optional values, choices, or a combination.
– <parameter>. The <> angle brackets indicate that a mandatory parameter must be entered
in place of the brackets and text inside them.
– [parameter]. The [] square brackets indicate that an optional parameter may be entered in
place of the brackets and text inside them.
– choice1 | choice2. The | indicates that only one of the parameters should be entered.
– The {} curly braces indicate that a parameter must be chosen from the list of choices.
Values
ipaddr This parameter is a valid IP address, made up of four decimal
bytes ranging from 0 to 255. The default for all IP parameters
consists of zeros (that is, 0.0.0.1). The interface IP address of
0.0.0.0 is invalid. In some cases, the IP address can also be
entered as a 32-bit number.
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 number 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-deci-
mal notation (for example, 0.0.0.1). A router ID of 0.0.0.0 is
invalid.
slot/port This parameter denotes a valid slot number and a valid port num-
ber. For example, 0/1 represents slot number 0 and port number 1.
The <slot/port> field is composed of a valid slot number and a
valid port number separated by a forward slash (/).
5-2 Command Line Interface Structure
December 2004, 202-10010-02
Page 35
User Manual for the NETGEAR 7200 Series Layer 2 Managed Switch Software
logical slot/port This parameter denotes a logical slot number and logical port
number assigned. This is applicable in the case of a port-channel
(LAG). The operator can use the logical slot number and the logical port number to configure the port-channel.
Conventions
Network addresses are used to define a link to a remote host, workstation or network. Network
addresses are shown using the following syntax:
Table 5-1. Network Address Syntax
Address Type Format Range
ipaddr
macaddr
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.
A.B.C.D 0.0.0.0 to 255.255.255.255
(decimal)
YY:YY:YY:YY:YY:YY hexidecimal digit pairs
Empty strings (““) are not valid user defined strings.
Command completion finishes spelling the command when enough letters of a command are typed
to uniquely identify the command word. The command may be executed 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 handled correctly.
The value of '-----' designates that the value is unknown.

Quick Start up
The CLI Quick Start up details procedures to quickly become acquainted with the 7200 Series L2
Switch.
Quick Starting the Switch
1. Read the device Installation Guide for the connectivity procedure. In-band connectivity allows
access to the 7200 Series L2 Switch 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, NETGEAR suggests logging into an administrator
account.
• Do not enter a password because there is no password in the default mode.
• Press the enter key two times.
• The CLI User EXEC prompt will be displayed.
• Use “enable” to switch to the Privileged EXEC mode from User EXEC.
• Use “configure” to switch to the Global Config mode from Privileged EXEC.

User Manual for the NETGEAR 7200 Series Layer 2 Managed Switch Software
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 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: $(Exec)>
Privileged Exec Mode To have access to the full suite of commands, the operator must
enter the Privileged Exec mode. The Privileged Exec mode
requires password authentication. From Privileged Exec mode,
the operator can issue any Exec command or enter the Global
Configuration mode. The command prompt shown at this level is:
Command Prompt: $(Exec)#
Global Config Mode This mode permits the operator to make modifications to the run-
ning 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 config,
the Interface Configuration mode, or the Protocol Specific modes
specified below. The command prompt at this level is:
Command Prompt: $(Config)#
From the Global Config mode, the operator may enter the following config modes:
VLAN Mode This mode groups all the commands pertaining to VLANs. The
command prompt shown at this level is:
Command Prompt: $(VLAN)#
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 con-
nection operation. The Interface Config mode provides access to
7-4 Mode-based CLI
December 2004, 202-10010-02
Page 49
User Manual for the NETGEAR 7200 Series Layer 2 Managed Switch Software
the router interface configuration commands. The command
prompt at this level is:
Command Prompt: $(Interface <slot/port>)#
The resulting prompt for the interface configuration command
entered in the Global Configuration mode is shown below:
$(Config)# interface 2/1
$(Interface 2/1)#
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: $(Line)#
Flow of Operation
This section captures the flow of operation for the CLI:
1. The operator logs into the CLI session and enters the User Exec mode. In the User Exec mode
the $(exec)> prompt is displayed on the screen.
The parsing process is initiated whenever the operator types a command and presses <ENTER>.
The command tree is searched for the command of interest. If the command is not found, the
output message indicates where the offending entry begins. For instance, command node A has the
command
brief” then the output message would be $(exec)> show arpp brief^. $%Invalid input detected at '^'
marker.
“show arp brief” but the operator attempts to execute the command “show arpp
If the operator has given an invalid input parameter in the command, then the message
conveys to the operator an invalid input was detected. The layout of the output is depicted below:
(exec) #show arpp brief
^
%Invalid input detected at ‘^’ marker.
FIGURE 2. Syntax Error Message
Mode-based CLI 7-5
December 2004, 202-10010-02
Page 50
User Manual for the NETGEAR 7200 Series Layer 2 Managed Switch Software
After all the mandatory parameters are entered, any additional parameters entered are treated as
optional parameters. If any of the parameters are not recognized a syntax error message will be
displayed.
2. After the command is successfully parsed and validated, the control of execution goes to the
corresponding CLI callback function.
3. For mandatory parameters, the command tree extends till the mandatory parameters make the
leaf of the branch. The callback function is only invoked when all the mandatory parameters
are provided. For optional parameters, the command tree extends till the mandatory
parameters and the optional parameters make the leaf of the branch. However, the call back
function is associated with the node where the mandatory parameters are fetched. The call
back function then takes care of the optional parameters.
4. Once the control has reached the callback function, the callback function has complete
information about the parameters entered by the operator.
“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. The behavior and the support
details of the “no” form is captured as part of the mapping sheets. The mapping sheets are
contained in the Appendix A, “IS CLI Mapping section.
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 interface’
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.
Behavior of Command Help (“?”)
The “no” form is treated as a specific form of an existing command and does not represent a new
or distinct command. This implies that the behavior of the “?” and help text is the same for the
“no” form:
• The help message is the same for all forms of the command. The help string may be
augmented with details about the “no” form behavior.

Switching Commands
This chapter provides detailed explanation of the Switching commands. The commands are
divided into five functional groups:
• Show commands display switch settings, statistics, and other information.
• Configuration Commands configure features and options of the switch. For every
configuration command there is a show command that displays the configuration setting.
• Copy commands transfers or saves configuration and informational files to and from the
switch.
• Clear commands clear some or all of the settings to factory defaults.
This chapter includes the following configuration types:
• System information and statistics commands
• Management commands
• Device configuration commands
• User account management commands
• Security commands
• System utilities
