original Enterprise OS software ﬂash memory card in a safe place and protect it

from accidental damage.

CHANGING THE BOOT SOURCE

This chapter describes how to change the primary boot source on a bridge/router or

tunnel switch.

The Enterprise OS software boot ﬁles for the main processor module are factory

shipped with a:/primary/boot.29k as the default primary boot source for NETBuilder

bridge/routers. If you have installed the Enterprise OS software ﬂash memory card

into drive A, and you want to keep the default boot source, go to Chapter 4.

If you want to adjust system conﬁguration settings, see the SysconF appendix in

Reference for Enterprise OS Software for instructions.

3Com recommends that you initially use the ReBoot command to boot the

bridge/router or tunnel switch. If this command fails, use the BT command.

Using the Boot

Command

The Boot Monitor utility Boot (BT) command allows you to reboot or to override the

default boot path. The BT command is useful if the boot path has a typing error or

if you have a malfunctioning drive. If you enter a new boot path, the Primary Boot

Source parameter is updated to reﬂect the new path.

To reboot the NETBuilder II bridge/router (or tunnel switch) using the Boot Monitor

utility Boot command, follow these steps:

1 Reset the system in one of two ways. Either press the two outer buttons on the LCD

control panel on the front of the NETBuilder chassis, or press the reset button on

3 Enter a boot path using:

BT <drive>:/<path>/<filename>

If you do not enter the <drive> value, drive A is used. To boot from drive A, enter:

BT a:/primary/boot29.k

The system attempts to boot from the speciﬁed image ﬁle. If an error occurs, a

message is sent to the console and you are returned to the boot monitor.

For more information about the Boot Monitor utility, see the Boot Monitor

appendix in Reference for Enterprise OS Software.

Conﬁguring the

Primary Boot Source

Drive A is the default primary boot source. This procedure establishes drive B as

the primary boot source.

This procedure is provided as an example showing how to use the command.

For actual operations, 3Com recommends that you boot from drive A and assign

drive B to capture dumps.

Prerequisites Before beginning this procedure, complete the following tasks:

■

Install the system software and boot the NETBuilder II system according to the

i n structions in Chapter 2.

Attach a terminal, a PC with a terminal emulation program, or a modem for

using a remote PC to the console port on the main processor module and

make sure the terminal is operating properly. If the terminal is not operating

properly, see the hardware installation guide for setup instructions.

Procedure To change the primary boot source to a drive or ﬁle other than the default or the

current drive setting, follow these steps:

1 Press the Return key.

The following prompt is displayed on your console:

NetLogin:

2 Log on as root by entering:

version 11.3 must be installed in drive B.

CHAPTER 3: CHANGING THE BOOT SOURCE

CONFIGURING BASIC SETTINGS

This chapter describes preliminary tasks for conﬁguring basic bridge/router

settings. Before you begin conﬁguring ports and paths (described in Chapter 1 of

Using Enterprise OS Software), complete the following tasks:

■

Log on to the system.

Familiarize yourself with the user interface.

Learn how to get help.

Set up IP routing.

Store conﬁguration parameter values.

Obtain Network Manager privileges.

Change the Network Manager password.

Set the time and date.

Set system administrator information.

Assign IP addresses and subnet masks to individual ports or one address for the

bridge/router or tunnel switch.

■

Set up the Simple Network Management Protocol (SNMP).

Set up NETBuilder security.

To perform these tasks, you can either attach a console to the console port and log

onto the system locally, or you can use the Web Link applications, which is a

web-based conﬁguration tool. For information on how to log on to the system

locally, see “L o gg i n g on to the S ys t em” on page 17.

Web Link contains a complete user interface to the conﬁguration parameters

required to set up and conﬁgure a bridge/router or tunnel switch.

Logging on to the

System

To log on to the bridge/router or tunnel switch, follow these steps:

1 Turn the bridge/router on or press the two outer (reset) buttons on the LCD panel

on the front of the chassis.

The bridge/router takes a few minutes to complete the initialization process.

Startup messages appear on your console display.

When you see the following message:

System Initialized and Running

the bridge/router has ﬁnished booting.

2 Press the Return key.

The following prompt is displayed on your console:

NetLogin:

CHAPTER 4: CONFIGURING BASIC SETTINGS

3 Log on as root:

root

4 Press the Return key.

Pressing the Return key when prompted for the password enters a null string,

which is the default local password. Later in this chapter, you will be instructed on

how to change the password.

The bridge/router system prompt is displayed:

Enterprise OS #

You are now ready to begin entering software commands.

Setting Up IP Routing

You must set up the port that accesses the server for IP routing. To set up IP

routing, follow these steps:

1 Log on as root and press the Return key.

The password prompt is displayed.

2 At the password prompt, press the Return key.

The network manager prompt (Enterprise OS #) is displayed.

3 Set up an IP address and subnet mask using:

SETDefault !<port> -IP NETaddr = <IP address> [<subnet mask>]

For more information on IP conﬁguration, see Reference for Enterprise OS

Software.

This step needs to be completed using the console port before telnet or Web Link

can be used.

4 Enable IP routing by entering:

SETDefault -IP CONTrol = RO

5 Enable a routing protocol. For example, to enable RIP use:

SETDefault !<port> -RIPIP CONTrol = (Listen, Talk)

This step is optional.

6 Ensure your conﬁguration by verifying that the bridge/router can access other

devices on the network, use:

PING <IP address>

where <IP address> is the IP address of another device on the network.

Learning About the

User Interfaces

This section describes how to access the bridge/router user interface and provides

an overview of the Web Link, menu-driven, and command-line interfaces.

This section also includes the following information:

■

How to specify values, set members, or set addresses when using either the

Web Link, menu-driven or command-line interface

■

How to use online help

Learning About the User Interfaces

Accessing the User To access the user interface or to modify the conﬁguration of the bridge/router or

Interface tunnel switch, use one of the following methods:

■

Access the bridge/router commands locally through the console port.

■

Establish an HTTP session with the bridge/router using the Web Link

application.

■

Establish a Telnet session with the bridge/router using security passwords.

Use a device (for example, a workstation) on the same extended network or

internetwork to access the bridge/router through the Telnet protocol.

Enterprise OS software also supports outgoing Telnet.

The software supports TCP and UDP over Bigger Addresses (TUBA), which

means you can Telnet to the bridge/router using an IP address or an OSI NSAP

address from a PC or workstation. For more information about using Telnet on

a workstation, see the manual that accompanies the workstation.

■

View and conﬁgure a subset of bridge/router parameters from a remote host

using SNMP. For information on preparing the bridge/router to run SNMP, see

Using Enterprise OS Software.

Web Link Versus After accessing the bridge/router user interface, you can issue a command in one

Menu-Driven Versus of three ways:

Command-Line Interface

■

Use the Web Link application if you are unsure of the command syntax and you

have a compatible web-based browser on your network management station.

■

Use the menu-driven interface if you are unsure of the command syntax.

For more information about the MEnu command, see Reference for

Enterprise OS Software. For information on how to use the menu-driven

interface, see the next section.

■

Enter the command at the system prompt if you know the exact syntax.

For information about the command line and rules for entering commands, see

“U si n g the Command-L i n e I n terface” on page 21.

The syntax for each command and parameter is described in Reference for

Enterprise OS Software.

Using the Web Link To log onto and conﬁgure a bridge/router using Web Link, follow these steps:

Application

1 Install the hardware and install all cables.

2 Log on to the system and set up IP rout i n g. S e e “S e tt i n g U p IP R o ut i n g” on

3 Set up your management workstation with a valid IP address.

To communicate with the bridge/router or tunnel switch, the IP address of the

management station should be an unused IP address in the range 10.1.0.2 -

10.1.255.254; subnet mask 255.255.0.0.

Once your management station possesses a valid IP address, the Web Link

application can be opened in the web browser running on the management

station.

4 Point your browser at the bridge/router interface IP address.

You are prompted to enter a user name and password.

CHAPTER 4: CONFIGURING BASIC SETTINGS

6 Click the OK button to enter a null string as the password, which is the default local

password.

The default Web Link page opens in the browser window.

Web Link Interface Description

The Web Link application window has three frames. All of the frames can be resized

by dragging the frame borders using the left mouse button.

Web Link Banner Frame Click Help, Documentation, the 3Com Library, 3Com

Support, and 3Com Contacts in the banner to access these resources.

The Conﬁguration shortcut takes you to the conﬁguration form for the

bridge/router or tunnel switch. The Diagnostics shortcut provides access to further

diagnostics of the bridge/router or tunnel switch. The Health shortcut provides

access to device statistics.

Web Link Navigator Frame The Web Link Navigator Frame provides links to the

Health, Conﬁguration, Diagnostics and Help Functions

Web Link Summary Frame The Summary Frame contains a graphic of the

device being conﬁgured and a form showing current values for the selected

parameters.

After you have entered Web Link, you can use the options to conﬁgure whatever

services are required.

Using the Menu-Driven The MEnu command allows you to perform the following operations:

Interface

■

List the services available on the bridge/router or tunnel switch.

Choose a service and see the list of parameters available for the service.

List the parameters in the current service.

Choose a parameter and see the commands used with it.

Check the active and default values of a particular parameter.

Display the syntax of a particular parameter.

Enter the new value of a parameter.

To use the menu-driven interface, you must have Network Manager privilege. When

using the menu-driven interface, you cannot access some parameters; for example,

you cannot alter the number of lines on the screen, or change privilege level.

Accessing the NETBuilder bridge/router through the REMote command requires the

command-line interface.

To use the menu-driven interface, follow these steps:

1 Access the main menu by entering:

Learning About the User Interfaces

The Main menu (Level 1) is displayed.

Depending on your software package, the number of services in your Main menu

may vary.

2 Select the service you want to use.

For example, selecting 1 from the Main menu (Level 1) display generates a menu

for the SYS Service.

3 Select the parameter you want to conﬁgure.

For example, if you select the NMPrompt parameter from the SYS Service menu

(Level 2) menu, information for that parameter is displayed.

The ﬁrst part of the screen displays the value of the parameter; the second part

S u bst i t ut i o n” on page 26 , and “Command-L i n e P a rameter A t tr i b utes” on

page 27.

4 To return to the previous menu level, press the Return key.

If you are at the Main menu (level 1) and press the Return key, you return to the

command-line interface.

Using the This section describes how to enter commands and provides detailed information

Command-Line Interface about using the command-line interface.

To use the command-line interface, follow these steps:

1 Type the command name.

If the command does not include a service name, parameter, or values, skip to

step 3. If the command requires more information or if you want to include

optional arguments, continue to step 2a.

If y o u need he l p i d ent i fyi n g the parts of a command, see F i g ure 1.

If the command has additional options, such as a port or path number, include

them after the command name.

Including a speciﬁc port or path number in the command focuses the

command on that port or path. If the port or path number is not included, the

command acts on all ports or paths.

For more information on ports and paths, see Chapter 1 in Using Enterprise OS

Software. For more information on commands, see Chapter 1 in Reference for

Enterprise OS Software.

b If the command includes a parameter, type the service name (if necessary), the

parameter name, and values.

The service name focuses the action of the command on a particular

bridge/router or tunnel switch service.

In some cases, you may not need to enter the service name. For example, if a

parameter is unique to a service, the service does not need to be speciﬁed. If

two or more services have parameters of the same name, you must include the

service name in the syntax. For more i n format i o n, see “E n ter i n g S e rvice Names

in Command L i n es” on page 25.

CHAPTER 4: CONFIGURING BASIC SETTINGS

The value part of the command speciﬁes how you want the parameter to be

set. Values include numerics, strings, or addresses, depending on the

parameter. F o r add i t i o nal i n format i o n, see “S y n tax for A ssigning V a l u es” on

page 28.

2 After entering the complete command, press the Return key.

The bridge/router software includes online help for commands, services,

parameters, and s y n ta x , d escribed in “G ett i n g H e l p ” on page 28. The syntax that

appears in online help is the full-form syntax; it contains full names and visual cues

for entering commands. You can also enter commands using an abbreviated

version of the syntax.

For information on full-form and abbreviated syntax, read the following sections

and see F i g ure 1 and F i g ur e 2. F o r add i t i o nal i n format i o n on short cuts for

syntax from the abbreviated form. You can enter a command in abbreviated form

by typing only the uppercase portion. It does not matter whether you type the

command in upper- or lowercase letters.

Abbreviated Syntax

Abbreviated syntax is the shortest unambiguous abbreviation of a command,

parameter, or value that can be entered. You can enter the abbreviated form in

lower- or uppercase letters at the Enterprise OS prompt.

Fi g ure 2 shows the abbreviated syntax that corresponds to the full-form syntax in

Symbols

You may see a variety of symbols shown as part of the command syntax. These

symbols usually explain how to enter the command, and you do not type them as

part of the command itself. The exceptions to this rule are parentheses, the

hyphen, and the exclamation point, which you do type as part of the command.

T a b l e 3 summarizes command syntax symbols.

Table 3 Command Syntax Symbols

Symbol

Description

angle brackets < > Enclose a variable or value. You must specify the variable or value; for

example, in the syntax:

DELete -IP ADDRess <IP address>

you must supply an address for <IP address> when you enter the

command. Do not type the angle brackets.

square brackets[ ] Enclose an optional value or a list of optional arguments. One or more

values or arguments can be specified. For example, in the syntax:

SET PRIvilege = [User | NetMgr]

you can specify either User or NetMgr when you enter the command. Do

not type the square brackets.

parentheses ( )

Enclose a list of values that can be assigned to a single parameter. At least

one of them must be selected. You must type the parentheses and

separate the values with a comma if you are assigning more than one

value. For example, in the syntax:

SET CurrentPorts = ALL | (<port>, <port>)

you can specify two port numbers by enclosing them in parentheses and

separating them with a comma when you enter the command.

vertical bar |

ellipsis ...

Separates mutually exclusive items in a list, one of which must be

entered. For example, in the syntax:

SET ScreenLength = [None | <line>(6–100)]

you can specify either the word None or a number between 6 and 100

when you enter the command. Do not type the vertical bar.

Following a parameter name or value, indicates that one or more

additional arguments may be specified on the same command line. For

example, in the syntax:

ADD !<port> -IP SecAuthIn <authority> [<authority> ...]

[ANY]

you can specify multiple authorities (GENSER, SIOP, SCI, NSA, DOE,

NONE) when you enter the command. Do not type the ellipsis.

CHAPTER 4: CONFIGURING BASIC SETTINGS

Table 3 Command Syntax Symbols (continued)

Symbol

Description

hyphen -

A letter preceded by a hyphen represents a command option. Also, when

you enter a service name as part of the command, you must precede the

service name with a hyphen. For example, in the command:

SETDefault -BRidge CONTrol = Bridge

You must include the hyphen with the service name BRidge when you

enter the command.

braces { }

Enclose a list of values, one of which must be entered. For example, in

the syntax:

SETDefault !<subaddr #> -Gateway SubAddrMap = {(<IPaddr>

| <PSAPaddr>) | None}

you must enter either an IP address, PSAP address, or the word None

when you enter the command. Do not type the braces.

exclamation point ! A number preceded by an exclamation point represents a port, virtual

port, or path number. For example, in the syntax:

SHow [!<port>] -DECnet CONFiguration

the exclamation point must be included before the port number when

you enter the command.

The exclamation point is also used to see a profile number. See the

PROFile Service chapter in Reference for Enterprise OS Software.

Full and Abbreviated Syntax Examples

The following examples show the full form ﬁrst, followed by the abbreviated

command syntax.

The full-form command syntax:

ADD !<port> -NRIP AdvToNeighbor <network>%<mac address> [...]

can be abbreviated to:

ADD !<port> -NRIP ATN <network>%<mac address> [...]

Replacing the variables in this abbreviated command syntax with values might

specify, for example, that a neighbor on port 2, network number &10, with

address % 080002030ef2, receives RIP and SAP updates:

ADD !2 -NRIP ATN &10%080002030ef2

The full-form command syntax:

SETDefault -IP CONTrol = ([ROute | NoROute], [RelaySrcRoute |

NoRelaySrcRoute], [SplitLoad | NoSplitLoad], [Filtering | NoFiltering],

[SECurity | NoSECurity], [FwdSubnetBcast | NoFwdSubnetBcast],

[FwdAllSubnetBcast | NoFwdAllSubnetBcast])

can be shortened by abbreviating it to:

NSEC],[FSB | NFSB], [FASB | NFASB])

The following command uses this abbreviated syntax to enable IP routing, packet

ﬁltering, and security:

SETD -IP CONT = (RO, F, SEC)

Learning About the User Interfaces

Variations in Command Syntax

Each command has its own syntax. When a command is used for conﬁguring

parameters, its syntax or values may change according to the parameter and

service. For example, the SETDefault command sets the NetMapTime parameter in

the SYS Service and the MaxAge parameter in the STP Service. In the following

example, the general syntax is followed by the syntax variations (different values

for different parameters) appropriate to each parameter:

SETDefault <parameter> = <value>

SETDefault -SYS NetMapTime = <number>(0 to 120 seconds)

SETDefault -STP MaxAge = <second> (6-40)

Entering Service Names in Command Lines

When you are conﬁguring or displaying parameters that appear in more than one

service, you must provide a service name to distinguish them. You can enter the

service name in abbreviated form, but the name must be preceded by a hyphen.

For example, to indicate BRidge Service, type -BR.

Abbreviated service names are indicated in uppercase in this guide.

There are three exceptions:

■

If you have previously set the CurrentServices parameter to the desired service,

you do not need to enter the service name. The system prompt indicates the

current service if you set a single service with the CurrentServices parameter.

For information on using the CurrentServices parameter, see Reference for

Enterprise OS Software.

■

Environment parameters do not have a service name. For descriptions of these

parameters, see Reference for Enterprise OS Software.

You do not need to enter a service name when the parameter name is unique.

Determining the Display of Ports and Virtual Ports

You can control which ports are displayed in the output of the SHow and

SHowDefault commands by setting the CurrentPorts parameter. If you have a

bridge/router with several ports, for example a NETBuilder II bridge/router with

multiport I/O modules installed, you may want to limit the display to information

on certain ports instead of all ports. If you are interested only in displaying

information for port 2 and virtual port V3, as well as the paths mapped to these

ports, set the CurrentPorts parameter by entering:

SET CurrentPorts = (2, V3)

Now when you enter SHow and SHowDefault commands, only information for

port 2 and virtual port V3, and the paths mapped to these ports, is displayed.

If you have a NETBuilder II bridge/router with a multiport module installed, you

must enter its ports individually when setting the CurrentPorts parameter. For

instance, if you have an Ethernet 2-Port 10BASE-FL module, the A and B ports are

distinct. If you specify port 1 with the CurrentPorts parameter, the software

assumes you mean port 1A. For information on port and path numbering

conventions for multiport modules, see Chapter 1 in Using Enterprise OS

CHAPTER 4: CONFIGURING BASIC SETTINGS

Software. For more information about the CurrentPorts parameter, see Reference

for Enterprise OS Software.

The syntax convention for ports, virtual ports, and group ports is:

!<port>

For a port, <port> is a variable ID number, for example, !1. For a virtual port or

group port, <port> is the letter V followed by a variable ID number, for example,

!V1.

When you create a virtual port or group port, it functions in the same way as a port.

Unless otherwise speciﬁed, the term “port” refers to virtual ports and group ports as

well as ports. For more information on ports, virtual ports, and group ports, see

Chapter 1 in Using Enterprise OS Software.

Using Aliases

To avoid entering lengthy commands, you can create an alias to represent any

command. To deﬁne an alias, use:

ADD -SYS ALias <alias name> <arguments…>

For example, if you use the SHow -SYS NetMAP command often, create an alias

called ntmap by entering:

ADD -SYS ALias ntmap SHow -SYS NetMAP

When you want to display the network map, at the bridge/router prompt enter:

ntmap

For more information about aliases, see Reference for Enterprise OS Software.

Command History Substitution

The bridge/router “remembers” the last 10 commands you enter. To display a list of

these commands, at the bridge/router prompt enter:

SHow History

For more information see Reference for Enterprise OS Software. Each command in

the display is numbered. To repeat any of the commands, use the event designator,

represented by an exclamation point (!).

You can use history substitution with the following options:

Repeats the previous command.

!<n>

Repeats the command numbered <n>. For example,

entering !100 repeats the command numbered 100. If

you know the command number, you do not need to

display it ﬁrst.

!-<n>

Repeats the command whose number is the current

command number minus <n>. The current command

number is shown on the screen preceding the

bridge/router prompt. For example, if the current

command is 100 and <n> is 2, command number 98 is

repeated.

Learning About the User Interfaces

!<string>

Repeats the most recent command that starts with the

variable <string>. The SHow History command might

display:

166 setdefault !1 -path control = enabled

167 show -path configuration

168 show history

169 set screenlength = 23

170 setdefault -bridge control = bridge

171 show statistics ?

If you enter !SETD at the prompt, the most recent

occurrence of the SETDefault command is executed:

setdefault -bridge control = bridge

!?<string>

Repeats the most recent command containing <string>.

In the preceding example, if you enter !?stat, the

command show statistics ? (number 171) is executed.

You can also repeat a previous command with

modiﬁcations by using the syntax described next.

^<string1>

Repeats the most recent command that contains

^<string1>^<string2> <string1>. If <string2> is speciﬁed, it replaces <string1>

in that command. For example, suppose you made a

typing mistake when you entered the following

SETDefault command:

seed welcomestring = “You are talking to the 3Com NETBuilder”

To repeat the command with the correct spelling of SETD,

you do not need to reenter the entire command. Enter:

^seed^setd

The following command is then displayed and executed:

setd welcomestring = “You are talking to the 3Com NETBuilder”

Privilege Level

The privilege level determines which commands and parameters a user can access.

The network manager must set the Network Manager password and the User

password to be the same in order to provide equal levels of security. If only the

Network Manager password is set, any other user receives User level privileges.

S e e “Chang i n g the P a ssword” for more information.

You can change the privilege level with the SET PRIvilege command. For more

information, see Reference for Enterprise OS Software.

Command-Line Parameter values, set members, and addresses can be expressed either as numbers

Parameter Attributes or as text. This section provides guidelines for specifying numeric values, strings,

and addresses. For details on the values permitted for each parameter, see

Names

Strings

Usually represent either system-defined parameter or

parameter values (written as param-name or value) or

user-defined macros or files (written as macroname or

filename).

Route, None

Some parameter values can be set to user-defined strings,

ranging from a single character (written as char) to a

multicharacter string (written as string).

“A,” “B,”

“password”

Addresses Two types of addresses can be assigned: media addresses for #311040800245,

Ethernet, FDDI, token ring, and wide area protocols (SMDS,

X.25, Frame Relay) and network layer addresses.

129.213.24.30

The SET, SETDefault, and SYSgen commands require both parameter names and

parameter values. The parameter name is followed by an equal sign (=) and a value.

Spaces are permitted, but not required, before and after the equal sign, for example:

SETDefault -SYS ScreenLength = 30

The ADD and DELete commands also require both parameter names and parameter

values. These commands modify sets of objects. No equal sign precedes the value

that is added or deleted as a set member, for example:

ADD -IP ADDRess 10.0.0.1 %080002001234

Numeric Values

To assign a hexadecimal value to a parameter, precede the number with a percent

sign (% ). Alphabetic characters can be entered in upper- or lowercase letters.

To assign a decimal number, type the number without any preceding symbol.

Names

To assign a name, type the name in the command. Names, unlike strings, do not

require quotation marks; however, the character length of the name may be limited.

Strings

String values fall into two categories: single characters and variable-length strings.

All alphanumeric characters and “Hello!”

symbols

Characters in a string are case-sensitive. For example, “ABC” is different from “abc.”

A few characters have special meaning to the bridge/router and must be preceded

by a backslash (\) in string text to prevent them from being misinterpreted. These

symbols are the apostrophe ('), backslash (\), caret (^), and quotation mark (“). For

Learning About the User Interfaces

example, to include an apostrophe in string text, enter a backslash followed by an

apostrophe (\'). To include a backslash (\) in string text, enter two backslashes (\\).

The ﬁrst backslash prevents the bridge/router from treating the second as a

special character.

When specifying AppleTalk zone strings, you can use the extended AppleTalk

ASCII character set. For more information, see Using Enterprise OS Software.

You can assign a string to the PATH NAme parameter, and use this string as an

instance identiﬁer. For example, you can assign the name “testnet” to path 2 by

entering:

SETDefault !2 -PATH NAme = “testnet”

In subsequent path-speciﬁc commands, you can substitute the path name for !2.

For example, if you want to set the connector type on path 2 after assigning a

name to this path, enter:

SETDefault !testnet -PATH CONNEctor = RS232

This same feature is available for port-speciﬁc commands. You can assign a name

to a port and then substitute the port name for !<port> in subsequent commands.

To assign a name to a port, use:

SETDefault !<port> -PORT NAme = “<string>”

For more information on the NAme parameter, see Reference for Enterprise OS

Software.

Port and Path Naming Restrictions

Port and path names are subject to the following restrictions:

■

The name string can contain a maximum of eight characters, the ﬁrst of which

must be alphabetic.

No blank spaces are allowed. The only nonalphanumeric characters allowed are

the asterisk (*), underscore (_), period (.), and hyphen (-).

Two ports or two paths cannot have the same name, but a port name can be

the same as a path name.

Alphabetic characters are stored and displayed as entered. Names are

case-insensitive when compared with previously entered names. For example,

port2 and PORT2 are evaluated as the same name.

ISDN-Related Syntax The syntax for some parameters is different for built-in Integrated Services Digital

Variation Network (ISDN) interfaces. The syntax variation for these parameters is presented

in Reference for Enterprise OS Software in the following format:

For non-ISDN interfaces SETDefault !<path> -PATH remoteDialNo = “<string>”

SHow [!<path> | !*] -PATH remoteDialNo

SHowDefault [!<path> | !*] -PATH remoteDialNo

For built-in ISDN interfaces SETDefault !<connectorID.channelID> -PATH remoteDialNo = “<string>”

SHow [!<connectorID.channelID> | !<connectorID>.*] -PATH remoteDialNo

SHowDefault [!<connectorID.channelID> | !<connectorID>.*] -PATH

remoteDialNo

CHAPTER 4: CONFIGURING BASIC SETTINGS

The syntax variation for non-ISDN interfaces applies to local area network (LAN)

and data terminal equipment (DTE) interfaces.

Enterprise OS software menus and help strings do not display the syntax variation

for ISDN interfaces.

The variation in syntax is caused partially by the different path-numbering

convention used for ISDN. For information, see Using Enterprise OS Software.

Special parameter values related to built-in ISDN interfaces can also cause a

variation in syntax.

Some parameters in ISDN-speciﬁc software are connector-related and require that

you specify a connector number (<connectorID>), for example, 2. Other

parameters are channel-related and require that you specify both a connector and

a channel number (<connectorID.channelID>), for example, 2.1. When you specify

both a connector and a channel number, you must separate them with a decimal

point.

If you do not specify a channel number in a command that requires both a

connector and a channel number, the software assumes the ﬁrst channel

associated with the connector. For example, if you specify connector number 2

when the syntax requires that you to specify both a connector and a channel

number, the software assumes you mean 2.1.

To specify all channels associated with a connector, specify the connector number,

a decimal point, and an asterisk, for example, 2.*

Address Formats The following summary describes media addresses and network layer addresses

the bridge/router uses and their formats. For detailed information on

protocol-speciﬁc addressing, see Reference for Enterprise OS Software.

Media Addresses

MAC

Contains 12 hexadecimal digits preceded by a percent sign (% ).

The NETBuilder II bridge/router has a media access control (MAC)

address (physical) for each LAN interface (Ethernet, FDDI, or token

ring), for each HSS interface, and for the main processor module.

The MAC address and the network identiﬁer constitute a network

address, which is the only address used by Xerox Network Systems

(XNS) and Internetwork Packet Exchange (IPX) routers. IP routers

have both MAC addresses for their LAN interfaces and Internet

addresses for their conﬁgured ports. Internet addresses are

described in “N e twork L a y e r A d dresses.”

Each MAC address is assigned by 3Com. A MAC address can be

displayed by entering:

SHow -SYS ADDRess

The following is an example of a MAC address:

% 080002001326

Learning About the User Interfaces

Frame Relay Requires an address called a Data Link Connection Identiﬁer (DLCI).

DLCIs are assigned by the appropriate authority at subscription

time. A DLCI follows an at sign (@) and can range from 1 through

1022 decimal. The DLCI identiﬁes a virtual circuit on the Frame

Relay network, and is used by the local bridge/router to send a

packet to a router on the other end of the circuit. The following is

an example of a Frame Relay address:

@22

In the standard (local) addressing convention, the DLCI number has

only local signiﬁcance; a duplicate number can be used by other

bridge/router or tunnel switches. In the global addressing

convention, identiﬁers used throughout the Frame Relay network

are unique, and all trafﬁc to a node has the same destination DLCI

number.

ATM

Consists of an 8-bit virtual path identiﬁer (VPI) and a 16-bit virtual

circuit identiﬁer (VCI), usually represented in VPI.VCI format, where

VPI is a decimal number between 0 and 255 and VCI is a decimal

number between 0 and 65,535. The following is an example of an

Asynchronous Transfer Mode (ATM) address:

107.44

Some vendors’ DSUs require an ATM address that consists of a 0-bit

VPI and a 10-bit VCI. In this case, the 10-bit VCI maps directly to a

Frame Relay DLCI.

SMDS

There are two types of Switched Multimegabit Data Service (SMDS)

addresses: individual addresses, for unicast trafﬁc, and group

addresses, for multicast trafﬁc. An individual address routes data to

a unique node. Packets sent to a group address are delivered to all

nodes that share that address. Both types of address begin with a

dollar sign. They are distinguished by the ﬁrst or control digit:

hexadecimal C for an individual address and hexadecimal E for a

group address. Each address has 15 decimal digits following the

control digit and resembles a telephone number. The software

automatically right-pads shorter addresses with hexadecimal F to

the full length. The following are examples of individual and group

SMDS addresses:

C14085551212FFFF

E14085551234FFFF

Individual Address

Group Address

X.25

Consists of up to 15 decimal digits and can vary in length. The

address looks similar to a telephone number and is preceded by a

pound sign (#). An X.25 address is also referred to as a data

terminal equipment (DTE) address.

When a device is attached to a public data network (PDN), the

network provider assigns it an X.25 address or an international data

number (IDN). The ﬁrst four digits indicate the country and PDN to

which the device is attached. The remaining digits represent a

unique device address determined by the network provider. The

following is an example of an X.25 address:

#311041503333

CHAPTER 4: CONFIGURING BASIC SETTINGS

ISDN

An ISDN address is a phone number provided by your

telecommunications carrier. It can include a dial preﬁx, country

code, area code, and phone number. It can consist of a maximum

of 30 characters. If you create a subaddress, you must separate the

phone number and the subaddress with a semicolon (;). The

subaddress can be composed of a maximum of 20 characters.

The following is an example of a valid ISDN address, including

a subaddress:

011122134567000;200

For complete information on ISDN addresses, see Using

Enterprise OS Software.

Netw ork Layer Addresses

AppleTalk

Consists of the network number and node ID. Each AppleTalk node

address is unique throughout the AppleTalk Internet. For details on

assigning an AppleTalk address, see Reference for Enterprise OS

Software. The following is an example of an AppleTalk address:

4.23

DECnet

Consists of an area address and a node address. The area number

identiﬁes the area to which the router belongs. Enter an area

number between 1 and 63. The node number assigned to the router

must be unique within the area. Enter a node number between 1

and 1,023. For details on assigning a DECnet address, see Reference

for Enterprise OS Software. The following is an example of a

DECnet address:

1.15

Internet

Also known as an IP address. It consists of up to 12 decimal digits

arranged in four three-digit ﬁelds separated by periods, as shown in

the following format:

xxx.xxx.xxx.xxx

Leading zeros can be omitted. For example, the following addresses

are the same:

010.002.002.001

10.2.2.1

An Internet address is required for:

■

A bridge/router port to perform IP routing

The bridge/router to be accessed via Telnet

The bridge/router to respond to the PING command from

another host

■

The bridge/router to participate in SNMP-based network

management

An address includes both a network number and a host number. The

actual format of these numbers varies depending on the class of

address being designated. Address class is determined by the value

in the ﬁrst octet of the address.

T a b l e 6 shows valid address classes, the range of the ﬁrst address

ﬁeld, and the resulting address format. The maximum value for any

single ﬁeld is 255.

† Class D addresses are used for multicast applications as assigned by the Internet Assigned

Numbers Authority (IANA).

For more information on Internet addresses, subnet masks, and

variable length subnet masks, see Using Enterprise OS Software.

IPX

Leading zeros can be omitted. Consists of an ampersand (&) followed

by a network address, which contains eight hexadecimal digits,

followed by the MAC address.

You may need to enter an IPX address when using the bridge/router

for IPX routing. The network address uniquely distinguishes one IPX

network from all other IPX networks. The following example

addresses are the same:

&00003333% 080002005678

&3333% 080002005678

OSI

Open System Interconnection (OSI) network addresses are called

network service access points (NSAPs). NSAPs are of variable length

and format, although they are always considered to have the

following three parts:

■

Area address (variable length)

System ID (six octets)

N-selector (one octet)

The system ID and N-selector are the last seven octets of the MAC

address, and the area address is everything but the system ID and

N-selector. The following is an example of an OSI address:

/49/0053080002A0089D01

where the area address is:

the system ID is:

/49/0053

080002A0089D

and the N-selector is:

For more information on the OSI addressing scheme, OSI routing

domains, and area addresses, see Using Enterprise OS Software.

VIP

A VINES Internet Protocol (VIP) address is globally unique, ﬁxed, and

permanent for servers and routers only. Each node has a two-ﬁeld,

48-bit Internet address, which is derived from the 32-bit VINES

network number and the 16-bit subnetwork number.

The Internet address has eight hexadecimal digits (VIP network ID)

and four hexadecimal digits (subnetwork ID) separated by a colon (:).

The Internet address (logical network) is independent of any data link

layer address assigned to a node on a physical medium. The

following is an example of a VIP address:

02A01339:0001

CHAPTER 4: CONFIGURING BASIC SETTINGS

XNS

Consists of a network address followed by a MAC address. The

network address distinguishes between different XNS Ethernet

networks. It contains eight hexadecimal digits, and is preceded by an

ampersand (&), which is used for identiﬁcation. Leading zeros can be

omitted. The following addresses are the same:

&3333% 080002001326

&00003333% 080002001326

Getting Help

The user interface provides help menus as memory aids. To display the help menu,

enter a question mark (?). The question mark can be used with different options as

described in T a b l e 7 .

Table 7 Online Help Syntax Summary

Syntax

Description

Displays the help menu. Different commands are displayed de-

pending on whether Network Manager privilege or User privilege is in

effect. The commands are organized according to services.

Displays a list of commands within the service.

For example, to display a list of commands in the SYS Service, enter:

-SYS?

If there are no commands under the service, a message is displayed to

indicate this. For example, enter this command at the prompt:

-IDP?

A message similar to the following appears:

No commands available in IDP service

command -service?

Displays a list of parameters that can be used with the command

within the service.

For example, to display a list of PORT Service parameters that can be

used with the SETDefault command, enter:

SETDefault -PORT?

Displays parameters by service name that can be used with the

command. Only parameters in services specified by the

CurrentServices parameter are displayed.

command -service

parameter?

Displays syntax for the command used with the parameter.

For example, to display the syntax for the SETDefault command used

with the CONTrol parameter in the SNMP Service, enter:

SETDefault -SNMP CONTrol?

Storing Conﬁguration

Parameter Values

Conﬁguration parameters are stored in ﬂash memory or on the disk of another

server (for example, the TFTP/FTP server that boots the bridge/router or tunnel

switch). In this guide, the term “disk” refers to either the local ﬂash memory drive

or the hard disk on another server.

When the bridge/router is booted, it copies conﬁguration parameters from the disk

to memory. Parameter values on the disk are default values and values in memory

are active values. You can alter the default and active values with the SETDefault

and SET commands. For more information, see Reference for Enterprise OS

Software.

When the new value of a parameter takes effect depends on whether its active

value has been changed. Some commands change the active value only, some

change the default value, and some change both. If you display the parameter after

Obtaining Network Manager Privilege Level

modifying it and see the new value, the new value has taken effect immediately. If

a command changes only the default value, the new value takes effect only after

reboot. In this guide, if the description does not specify when the new value of a

parameter takes effect after being enabled or disabled, it is effective immediately

after it is set.

Obtaining Netw ork

Manager Privilege

Level

Before changing the Network Manager password, you must obtain Network

Manager privilege.

To display or change the privilege level, follow these steps:

1 To determine the current privilege level, enter:

SHow PRIvilege

If the following message is displayed, you already have Network Manager privilege:

PRIvilege = NetMgr

If the following message is displayed, go to step 2:

PRIvilege = User

You also can determine the privilege level from the Enterprise OS prompt. The

following prompt is displayed at the Network Manager privilege level:

Enterprise OS #

The following prompt is displayed at the User privilege level:

Enterprise OS >

2 If you are currently at User privilege level, enter the following command to change

the privilege level from User to Network Manager:

SET PRIvilege = NetMgr

The following prompt is displayed:

Password:

3 Press the Return key.

A null string is entered, which is the default password.

After obtaining Network Manager privilege, proceed to the next section to change

the Network Manager password.

Changing the

Passw ord

Changing the Network Manager password prevents unauthorized users from

accessing the bridge/router or tunnel switch. You should change the password

immediately after you log on for the ﬁrst time.

The privilege level determines which commands and parameters a user can access.

Each level has its own password. You must set the Network Manager password and

the User password to be the same in order to provide equal levels of security. If only

the Network Manager password is set, any other user receives User level privileges.

Users with NetMgr privileges can lower their privileges without a password. Users

with User privileges cannot raise their privileges. To raise privileges after lowering

them, you must enter the password again.

The Network Manager password must be set before the User password. The User

password must be cleared before the Network Manager password.

CHAPTER 4: CONFIGURING BASIC SETTINGS

To change the password, follow these steps:

1 At the Enterprise OS prompt (Enterprise OS #), enter:

SysPassWord

When a menu is displayed, Select 1, Set Network Manager Privilege Password.

2 Enter the new Network Manager password. Retype it when prompted to do so.

You are returned to the SysPassWord menu.

3 Enter 2.

4 Enter the new User password and retype it when prompted to do so.

5 Press the Return key to exit the SysPassWord menu and return to the

Enterprise OS prompt (Enterprise OS #).

Go to the next section to set the time and date on the system.

Setting the Time and

Date

To set the time and date on your system, use:

SET -SYS DATE = YY/MM/DD HH:MM[:ss]

For example, to set the date and time to January 10, 1995, 9:40 a.m., enter:

SET -SYS DATE = 1995/1/10 09:40

The NETBuilder II bridge/router contains a real-time clock, so you do not need to

set the date after each reboot to keep it correct.

For more information on these parameters, see Reference for Enterprise OS

Software. Proceed to the next section to enter system administrator information.

Setting System

Administrator

Information

As system administrator, you can set the system name, location, and system

contact so that other system administrators can contact you for information. If you

are planning to use SNMP, you must set the system administrator information;

otherwise, these settings are optional.

Before performing the procedure, you need to decide on or obtain the following

information:

■

System name

System location

System contact person and phone number

To set system administrator information, follow these steps:

1 Specify a name for the node, using:

SETDefault -SYS SysNAMe = “<string>”

For example, to set the bridge/router name as “Sales.SanJose,” enter:

SETDefault -SYS SysNAMe = “Sales.SanJose”

The system name can contain no more than 255 characters. The default value is

“ “ (null string).

2 Specify the system location, using:

SETDefault -SYS SysLOCation = “<string>”

For example, to set the system location as “SecondFloor.Lab,” enter:

SETDefault -SYS SysLOCation = “SecondFloor.Lab”

Assigning Internet Addresses

The system location can contain no more than 255 characters. The default value is

“ “ (null string).

3 Specify a string that identiﬁes the contact person managing the bridge/router or

tunnel switch, using:

SETDefault -SYS SysCONtact = “<string>”

For example, to specify John Smith as the system contact and a number to reach him,

enter:

SETDefault -SYS SysCONtact = “John Smith (408) 555-1111”

The system contact string can contain no more than 255 characters. The default

value is “ “ (null string). Users can obtain this information by entering:

SHow -SYS SysCONtact

Proceed to the next section to assign an Internet address.

4 Specify a banner string to be displayed by the bridge/router or tunnel switch:

The banner string can contain no more than 110 characters. The default value is “ “

(null string). Use:

SETDefault -SYS BannerString = “<string>

The SYStem service BannerString parameter allows you to input a text string that is

used as a information message for a bridge/router or tunnel switch. The string can be

up to 110 characters long and is displayed immediately prior to the word

“NetLogin:” when you are connecting to a bridge/router console. The banner string

is suppressed if the InterAction parameter is set to NoLOGin. This banner string is

redisplayed with each login retry.

Assigning Internet

Addresses

This section describes how to assign one or more Internet addresses to the system

using the NETaddr parameter in the IP Service. Before you assign an Internet address,

you must determine:

■

Whether you want your network to connect to the Internet, and how to obtain a

unique Internet address.

Whether you want to use the system as a bridge, a router, a bridge/router or a

tunnel switch.

Whether you need subnet addressing.

If you have already decided on these issues, proceed to “A ssigning I n ternet

A d dresses to a B r idge” on page 37 or to “A ssigning I n ternet A d dresses to a R o uter”

on page 38. If you need more i n format i o n to make y o ur dec i si o n, see “Obta i n i n g an

I n ternet A d dress” on page 39 and see the subnet information in the Using

Enterprise OS Software.

Assigning Internet Even though a bridge does not route IP trafﬁc, it needs an Internet address to

Addresses to a Bridge participate in network management and to be accessible from other devices through

Telnet or the SNMP.

When assigning an Internet address to an entire bridge, assign the address to port 0

using:

SETDefault !0 -IP NETaddr = <IP address>

An Internet address assigned to port 0 is considered an Internet address for the

entire bridge.

CHAPTER 4: CONFIGURING BASIC SETTINGS

The following example illustrates how to assign an Internet address to a bridge.

Example F i g ure 3 shows a conﬁgurat i o n i n w h i ch y o u need to ass i g n an I n ternet address to

a bridge. Hosts A and B are two hosts belonging to the same IP network, network

10. The IP host on Network A has an Internet address 10.0.0.1, and the one on

Network B has an Internet address 10.0.0.2. The bridge forwards packets between

these segments. To allow communication between the hosts and the bridge, ports

1 and 2 must reside on the same network. Assigning the same network number to

two or more bridge ports is prohibited, so you must assign the address to the

entire bridge, entering a command similar to the following:

SETDefault !0 -IP NETaddr = 10.0.0.3

Assigning Internet If the bridge/router is used to route IP trafﬁc, you must conﬁgure the ports on

Addresses to a Router which IP packets are routed by assigning Internet addresses to them. You can

assign Internet addresses to individual ports using:

SETDefault !<port> -IP NETaddr = <IP address>

For more information, see the Reference for Enterprise OS Software.

CAUTION: Do not assign an Internet address to port 0, or the IP routing function

will be disabled.

The next example illustrates how to assign Internet addresses to a bridge/router or

tunnel switch.

Example I n Fi g ure 4, N e tworks A and B are two different IP networks, and the bridge/router

is used for routing IP packets and for bridging OSI packets. To assign an IP address

to port 1, enter a command similar to the following:

SETDefault !1 -IP NETaddr = 192.1.5.1

To assign an address to port 2, enter a command similar to the following:

SETDefault !2 -IP NETaddr = 192.1.3.1

Internet Address unique address from the central authority, the InterNIC. This central authority

provides the following services:

■

Registration Services

Assists in registering networks and domains, and assigns network numbers and

other entities to the Internet community.

■

Directory and Database Services

Maintains lists of FTP sites, various types of servers available on the Internet,

white and yellow page directories, library catalogs, and data archives. For more

information, phone (908) 668-6587 or use network mail

CHAPTER 4: CONFIGURING BASIC SETTINGS

If you do not plan to be connected to the Internet, you can assign network

addresses on your own. However, if you plan on accessing the Internet in the

future, you may want to apply for an Internet network address so you will not

have to change network addresses when you make the connection.

After obtaining your Internet address, see “A ssigning I n ternet A d dresses to a

B r idge” on page 37 or to “A ssigning I n ternet A d dresses to a R o uter” on page 38.

For additional information on Internet addresses and subnets, see Using

Enterprise OS Software.

Setting Up the Simple

Netw ork

Management Protocol

The bridge/router participates in different types of network management activities.

Most management activities require conﬁguration because they are disabled by

default. The bridge/router manages networks in the following ways:

■

Conﬁguring and monitoring from a UNIX or Windows network management

station using Transcend Enterprise Manager.

Remote upgrade management using the Enterprise OS Remote Upgrade

Management Utilities supplied on CD-ROM with every Enterprise OS release.

Building network maps (netmaps).

This guide does not describe in detail how to set up the SNMP Service. See Using

Enterprise OS Software and Reference for Enterprise OS Software for more

information.

SNMP allows you to modify and display some Enterprise OS parameters from a

network management station. You do not need to attach a terminal to the

bridge/router console port to change its conﬁguration. To implement SNMP, follow

speciﬁcations in RFC 1155, RFC 1157, and RFC 1213. System parameters

described in RFC 1213 and 3Com extended parameters can be accessed from the

host.

Modifying SNMP To enable SNMP read/write access, you need to modify two parameters in the

Parameters SNMP Service: COMmunity and MANager.

The COMmunity parameter is an SNMP Service parameter that modiﬁes the list of

communities. For information on how to use the COMmunity parameter, see

Using Enterprise OS Software and to Reference for Enterprise OS Software.

By default, the community name “ANYCOM” exists with read access to the

management information base (MIB) variables and allows unrestricted access to

the bridge/router or tunnel switch. To ensure that access is available only to the

proper system administrator, 3Com recommends that you delete the “ANYCOM”

community name, and add the appropriate community string and the IP address

of the manager.

To modify SNMP parameters, follow these steps:

1 Delete the default community string “ANYCOM” by entering:

DELete -SNMP COMmunity “ANYCOM”

2 Conﬁgure at least one new community string with read/write access.

For example:

ADD -SNMP COMmunity “private” TRiv RW AL1

3 Add other community strings with read-only access as required.

NETBuilder Security

For example:

ADD -SNMP COMmunity “public” TRiv RO AL1

4 Create a new manager with read/write access to the bridge/router or tunnel

switch. For security reasons, limit the number of network management stations.

For example:

ADD -SNMP MANager “private” 129.213.224.1 255.255.0

5 Enable the SNMP service by entering:

SETDefault -SNMP CONTrol = (Manage, Trap)

NETBuilder Security

NETBuilder security can be obtained many ways including limiting the access to a

particular network or by limiting the access to certain ﬁles. Limiting access to a

particular network can be accomplished by building Internet ﬁrewalls. Limiting

access to particular ﬁles can be accomplished by using certain commands and

parameters.

Building Firew alls for A ﬁrewall allows users inside a private network to have outbound access, while

Security restricting outside users from inbound access. For more conceptual information

about ﬁrewall and its capabilities, and details on how to conﬁgure ﬁrewalls, see

Using Enterprise OS Software. For a description and syntax of the various ﬁrewall

service parameters, see Reference for Enterprise OS Software.

Security Commands and To make sure that some designated ﬁles are accessible only to the system

Parameters administrator, use the following commands and parameters:

■

NetAccess

This parameter is a SYS Service parameter that determines how a bridge/router

can be accessed from another device on the network. For information on how

to use the NetAccess parameter, see Using Enterprise OS Software and

Reference for Enterprise OS Software.

■

SysPassWord

This command brings up a menu allowing you to specify the password for the

Network Manager and User privilege levels. For information on how to use the

SysPassWord command, see Reference for Enterprise OS Software.

RemoteManager

This parameter is a SYS Service parameter that speciﬁes the Internet addresses

of devices that can connect to the bridge/router through the REMote

command. For information on how to use the RemoteManager parameter, see

Using Enterprise OS Software and Reference for Enterprise OS Software.

■

COMmunity

This parameter is an SNMP Service parameter that modiﬁes the list of

communities. For information on how to use the COMmunity parameter, see

Using Enterprise OS Software and Reference for Enterprise OS Software.

What Next?

You are now ready to see Using Enterprise OS Software to conﬁgure your

bridge/router for your speciﬁc network needs.

advance replacement. The replacement product will normally be shipped not later than three (3) business days after 3Com’s

verification of the DOA product, but may be delayed due to export or import procedures. When an advance replacement is

provided and Customer fails to return the defective product to 3Com within fifteen (15) days after shipment of the

replacement, 3Com will charge Customer for the replacement product, at list price.

3Com shall not be responsible for any software, firmware, information, or memory data of Customer contained in, stored on,

or integrated with any products returned to 3Com for repair, whether under warranty or not.

WARRANTIES EXCLUSIVE

IF A 3COM PRODUCT DOES NOT OPERATE AS WARRANTED ABOVE, CUSTOMER’S SOLE REMEDY FOR BREACH OF THAT

WARRANTY SHALL BE REPAIR, REPLACEMENT, OR REFUND OF THE PURCHASE PRICE PAID, AT 3COM’S OPTION. TO THE FULL

EXTENT ALLOWED BY LAW, THE FOREGOING WARRANTIES AND REMEDIES ARE EXCLUSIVE AND ARE IN LIEU OF ALL OTHER

WARRANTIES, TERMS, OR CONDITIONS, EXPRESS OR IMPLIED, EITHER IN FACT OR BY OPERATION OF LAW, STATUTORY OR

OTHERWISE, INCLUDING WARRANTIES, TERMS, OR CONDITIONS OF MERCHANTABILITY, FITNESS FOR A PARTICULAR

PURPOSE, AND SATISFACTORY QUALITY. 3COM NEITHER ASSUMES NOR AUTHORIZES ANY OTHER PERSON TO ASSUME FOR

IT ANY OTHER LIABILITY IN CONNECTION WITH THE SALE, INSTALLATION, MAINTENANCE OR USE OF ITS PRODUCTS.

3COM SHALL NOT BE LIABLE UNDER THIS WARRANTY IF ITS TESTING AND EXAMINATION DISCLOSE THAT THE ALLEGED

DEFECT IN THE PRODUCT DOES NOT EXIST OR WAS CAUSED BY CUSTOMER’S OR ANY THIRD PERSON'S MISUSE, NEGLECT,

IMPROPER INSTALLATION OR TESTING, UNAUTHORIZED ATTEMPTS TO REPAIR OR MODIFY, OR ANY OTHER CAUSE BEYOND

THE RANGE OF THE INTENDED USE, OR BY ACCIDENT, FIRE, LIGHTNING, OR OTHER HAZARD.

LIMITATION OF LIABILITY

TO THE FULL EXTENT ALLOWED BY LAW, 3COM ALSO EXCLUDES FOR ITSELF AND ITS SUPPLIERS ANY LIABILITY, WHETHER

BASED IN CONTRACT OR TORT (INCLUDING NEGLIGENCE), FOR INCIDENTAL, CONSEQUENTIAL, INDIRECT, SPECIAL, OR

PUNITIVE DAMAGES OF ANY KIND, OR FOR LOSS OF REVENUE OR PROFITS, LOSS OF BUSINESS, LOSS OF INFORMATION OR

DATA, OR OTHER FINANCIAL LOSS ARISING OUT OF OR IN CONNECTION WITH THE SALE, INSTALLATION, MAINTENANCE,

USE, PERFORMANCE, FAILURE, OR INTERRUPTION OF ITS PRODUCTS, EVEN IF 3COM OR ITS AUTHORIZED RESELLER HAS BEEN

ADVISED OF THE POSSIBILITY OF SUCH DAMAGES, AND LIMITS ITS LIABILITY TO REPAIR, REPLACEMENT, OR REFUND OF THE

PURCHASE PRICE PAID, AT 3COM’S OPTION. THIS DISCLAIMER OF LIABILITY FOR DAMAGES WILL NOT BE AFFECTED IF ANY

REMEDY PROVIDED HEREIN SHALL FAIL OF ITS ESSENTIAL PURPOSE.

DISCLAIMER

Some countries, states, or provinces do not allow the exclusion or limitation of implied warranties or the limitation of incidental

or consequential damages for certain products supplied to consumers or the limitation of liability for personal injury, so the

above limitations and exclusions may be limited in their application to you. When the implied warranties are not allowed to be

excluded in their entirety, they will be limited to the duration of the applicable written warranty. This warranty gives you

specific legal rights which may vary depending on local law.

GOVERNING LAW
