Limited Warranty Statement: SMC Networks, Inc. (“SMC”) warrants its products
to be free from defects in workmanship and materials, under normal use and
service, for the applicable warranty term. All SMC products carry a standard 90-day
limited warranty from the date of purchase from SMC or its Authorized Reseller.
SMC may, at its own discretion, repair or replace any product not operating as
warranted with a similar or functionally equivalent product, during the applicable
warranty term. SMC will endeavor to repair or replace any product returned under
warranty within 30 days of receipt of the product.
The standard limited warranty can be upgraded to a Limited Lifetime* warranty by
registering new products within 30 days of purchase from SMC or its Authorized
Reseller. Registration can be accomplished via the enclosed product registration
card or online via the SMC web site. Failure to register will not affect the standard
limited warranty. The Limited Lifetime warranty covers a product during the Life of
that Product, which is defined as the period of time during which the product is an
“Active” SMC product. A product is considered to be “Active” while it is listed on
the current SMC price list. As new technologies emerge, older technologies become
obsolete and SMC will, at its discretion, replace an older product in its product line
with one that incorporates these newer technologies. At that point, the obsolete
product is discontinued and is no longer an “Active” SMC product. A list of
discontinued products with their respective dates of discontinuance can be found
at:
http://www.smc.com/index.cfm?action=customer_service_warranty.

may be either new or reconditioned. Any replaced or repaired product carries
either a 30-day limited warranty or the remainder of the initial warranty, whichever
is longer. SMC is not responsible for any custom software or firmware,
configuration information, or memory data of Customer contained in, stored on, or
integrated with any products returned to SMC pursuant to any warranty. Products

components, such as expansion modules, removed prior to returning the product
for replacement. SMC is not responsible for these items if they are returned with the
product.
Customers must contact SMC for a Return Material Authorization number prior to
returning any product to SMC. Proof of purchase may be required. Any product
returned to SMC without a valid Return Material Authorization (RMA) number
clearly marked on the outside of the package will be returned to customer at
customer’s expense. For warranty claims within North America, please call our
toll-free customer support number at (800) 762-4968. Customers are responsible for
all shipping charges from their facility to SMC. SMC is responsible for return

Connecting to the Switch
Configuration Options
The TigerSwitch 10/100/1000 includes a built-in network
management agent. The agent offers a variety of management
options, including SNMP, RMON and a Web-based interface. A PC
may also be connected directly to the switch for configuration and
monitoring via a command line interface (CLI).
Note: The IP address for this switch is assigned via DHCP by
default. To change this address, see “Setting an IP Address”
on page 1-7.
The switch’s HTTP Web agent allows you to configure switch
parameters, monitor port connections, and display statistics
graphically using a standard Web browser such as Netscape
Navigator version 6.2 and higher or Microsoft IE version 5.0 and
higher. The switch’s Web management interface can be accessed
from any computer attached to the network.
1
The switch’s management agent is based on SNMP (Simple
Network Management Protocol). This SNMP agent permits the
switch to be managed from any system in the network using
management software.
The CLI program can be accessed by a direct connection to the
RS-232 serial console port on the switch, or remotely by a Telnet
connection over the network.

ONNECTING TO THE SWITCH
Required Connections
The switch provides an RS-232 serial port that enables a
connection to a PC or terminal for monitoring and configuring the
switch. A null-modem console cable is provided with the switch.
Attach a VT100-compatible terminal, or a PC running a terminal
emulation program to the switch. You can use the console cable
provided with this package, or use a null-modem cable that
complies with the wiring assignments shown in Appendix C.
To connect a terminal to the console port, complete the following
steps:
1. Connect the console cable to the serial port on a terminal, or a
PC running terminal emulation software, and tighten the
captive retaining screws on the DB-9 connector.
2. Connect the other end of the cable to the RS-232 serial port on
the switch.
3. Make sure the terminal emulation software is set as follows:
• Select the appropriate serial port (COM port 1 or COM
port 2).
• Set the data rate to 9600 baud.
• Set the data format to 8 data bits, 1 stop bit, and no parity.
• Set flow control to none.
• Set the emulation mode to VT100.
• When using HyperTerminal, select Terminal keys, not
Windows keys.

WITCH MANAGEMENT
Note: When using HyperTerminal with Microsoft® Windows®
2000, make sure that you have Windows 2000 Service Pack
2 or later installed. Windows 2000 Service Pack 2 fixes the
problem of arrow keys not functioning in HyperTerminal’s
VT100 emulation. See www.microsoft.com for information
on Windows 2000 service packs.
4. Once you have set up the terminal correctly, the console login
screen will be displayed.
Note: Refer to “Line Commands” on page 3-80 for a complete
description of console configuration options.
For a description of how to use the CLI, see “Using the Command
Line Interface” on page 3-1. For a list of all the CLI commands and
detailed information on using the CLI, refer to “Command Groups”
on page 3-12.
Remote Connections
Prior to accessing the switch’s onboard agent via a network
connection, you must first configure it with a valid IP address,
subnet mask, and default gateway using a console connection,
DHCP or BOOTP protocol.
The IP address for this switch is assigned via DHCP by default. To
manually configure this address or enable dynamic address
assignment via DHCP or BOOTP, see “Setting an IP Address” on
page 1-7.
Note: This switch supports four concurrent Telnet sessions.
After configuring the switch’s IP parameters, you can access the
onboard configuration program from anywhere within the
attached network. The onboard configuration program can be
accessed using Telnet from any computer attached to the network.
The switch can also be managed by any computer using a Web
1-4

ASIC CONFIGURATION
browser (Internet Explorer 5.0 or above, or Netscape Navigator 6.2
or above), or from a network computer using network
management software.
Note: The onboard program only provides access to basic
configuration functions. To access the full range of SNMP
management functions, you must use SNMP-based network
management software.
Basic Configuration
Console Connection
The CLI program provides two different command levels —
normal access level (Normal Exec) and privileged access level
(Privileged Exec). The commands available at the Normal Exec
level are a limited subset of those available at the Privileged Exec
level and allow you to only display information and use basic
utilities. To fully configure switch parameters, you must access the
CLI at the Privileged Exec level.
Access to both CLI levels are controlled by user names and
passwords. The switch has a default user name and password for
each level. To log into the CLI at the Privileged Exec level using
the default user name and password, perform these steps:
1. To initiate your console connection, press <Enter>. The “User
Access Verification” procedure starts.
2. At the Username prompt, enter “admin.”
3. At the Password prompt, also enter “admin.” (The password
characters are not displayed on the console screen.)
4. The session is opened and the CLI displays the “Console#”
prompt indicating you have access at the Privileged Exec level.

S
WITCH MANAGEMENT
Setting Passwords
Note: If this is your first time to log into the CLI program, you
should define new passwords for both default user names
using the “username” command, record them and put them
in a safe place.
Passwords can consist of up to eight alphanumeric characters and
are case sensitive. To prevent unauthorized access to the switch,
set the passwords as follows:
1. Open the console interface with the default user name and
password “admin” to access the Privileged Exec level.
2. Type “configure” and press <Enter>.
3. Type “username guest password 0 password,” for the Normal
Exec level, where password is your new password. Press
<Enter>.
4. Type “username admin password 0 password,” for the
Privileged Exec level, where password is your new password.
Press <Enter>.

ASIC CONFIGURATION
Setting an IP Address
You must establish IP address information for the switch to obtain
management access through the network. This can be done in
either of the following ways:
Manual — You have to input the information, including IP
address and subnet mask. If your management station is not in the
same IP subnet as the switch, you will also need to specify the
default gateway router.
Dynamic — The switch sends IP configuration requests to
BOOTP or DHCP address allocation servers on the network.
Note: Only one VLAN interface can be assigned an IP address
(the default is VLAN 1). This defines the management
VLAN, the only VLAN through which you can gain
management access to the switch. If you assign an IP
address to any other VLAN, the new IP address overrides
the original IP address and this becomes the new
management VLAN.
Manual Configuration
You can manually assign an IP address to the switch. You may also
need to specify a default gateway that resides between this device
and management stations that exist on another network segment.
Valid IP addresses consist of four decimal numbers, 0 to 255,
separated by periods. Anything outside this format will not be
accepted by the CLI program.
Note: The IP address for this switch is assigned via DHCP by
default.
1-7
S
WITCH MANAGEMENT
Before you can assign an IP address to the switch, you must obtain
the following information from your network administrator:
• IP address for the switch
• Default gateway for the network
• Network mask for this network
To assign an IP address to the switch, complete the following
steps:
1. From the Privileged Exec level global configuration mode
prompt, type “interface vlan 1” to access the
interface-configuration mode. Press <Enter>.
2. Type “ip address ip-address netmask,” where “ip-address” is
the switch IP address and “netmask” is the network mask for
the network. Press <Enter>.
3. Type “exit” to return to the global configuration mode prompt.
Press <Enter>.
4. To set the IP address of the default gateway for the network to
which the switch belongs, type “ip default-gateway gateway,”
where “gateway” is the IP address of the default gateway. Press
<Enter>.
Console(config)#interface vlan 1
Console(config-if)#ip address 192.168.1.5 255.255.255.0
Console(config-if)#exit
Console(config)#ip default-gateway 192.168.1.254
Console(config)#
Dynamic Configuration
If you select the “bootp” or “dhcp” option, IP will be enabled but
will not function until a BOOTP or DHCP reply has been received.
You therefore need to use the “ip dhcp restart” command to start

broadcasting service requests. Requests will be sent periodically in
an effort to obtain IP configuration information. (BOOTP and
DHCP values can include the IP address, subnet mask, and default
gateway.)
If the “bootp” or “dhcp” option is saved to the startup-config file,
then the switch will start broadcasting service requests as soon as
it is powered on.
To automatically configure the switch by communicating with
BOOTP or DHCP address allocation servers on the network,
complete the following steps:
1. From the Privileged Exec level global configuration mode
prompt, type “interface vlan 1” to access the
interface-configuration mode. Press <Enter>.
2. At the interface-configuration mode prompt, use one of the
following commands:
• To obtain IP settings through DHCP, type “ip address
dhcp” and press <Enter>.
• To obtain IP settings through BOOTP, type “ip address
bootp” and press <Enter>.
3. Type “exit” to return to the global configuration mode. Press
<Enter>.
4. Type “ip dhcp restart” to begin broadcasting service requests.
Press <Enter>.
5. Wait a few minutes, and then check the IP configuration
settings, by typing the “show ip interface” command. Press
<Enter>.

Enabling SNMP Management Access
The switch can be configured to accept management commands
from Simple Network Management Protocol (SNMP) applications.
You can configure the switch to (1) respond to SNMP requests or
(2) generate SNMP traps.
When SNMP management stations send requests to the switch
(either to return information or to set a parameter), the switch
provides the requested data or sets the specified parameter. The
switch can also be configured to send information to SNMP
managers (without being requested by the managers) through trap
messages, which inform the manager that certain events have
occurred.
Community Strings
Community strings are used to control management access to
SNMP stations, as well as to authorize SNMP stations to receive
trap messages from the switch. You therefore need to assign
community strings to specified users or user groups, and set the
access level.
1-10
B
ASIC CONFIGURATION
The default strings are:
• public - with read-only access. Authorized management
stations are only able to retrieve MIB objects.
• private - with read-write access. Authorized management
stations are able to both retrieve and modify MIB objects.
Note: If you do not intend to utilize SNMP, it is recommended
that you delete both of the default community strings. If
there are no community strings, then SNMP management
access to the switch is disabled.
To prevent unauthorized access to the switch via SNMP, it is
recommended that you change the default community strings.
To configure a community string, complete the following steps:
1. From the Privileged Exec level global configuration mode
prompt, type “snmp-server community string mode,” where
“string” is the community access string and “mode” is rw
(read/write) or ro (read only). Press <Enter>.
2. To remove an existing string, simply type “no snmp-server
community string,” where “string” is the community access
string to remove. Press <Enter>.

WITCH MANAGEMENT
Trap Receivers
You can also specify SNMP stations that are to receive traps from
the switch.
To configure a trap receiver, complete the following steps:
1. From the Privileged Exec level global configuration mode
prompt, type “snmp-server host host-address
community-string,” where “host-address” is the IP address for
the trap receiver and “community-string” is the string
associated with that host. Press <Enter>.
2. In order to configure the switch to send SNMP notifications,
you must enter at least one snmp-server enable traps
command. Type “snmp-server enable traps type,” where “type”
is either authentication or link-up-down. Press <Enter>.
Console(config)#snmp-server enable traps link-up-down
Console(config)#
Saving Configuration Settings
Configuration commands only modify the running configuration
file and are not saved when the switch is rebooted. To save all
your configuration changes in non-volatile storage, you must copy
the running configuration file to the start-up configuration file
using the “copy” command.
To save the current configuration settings, enter the following
command:
1. From the Privileged Exec mode prompt, type “copy
running-config startup-config” and press <Enter>.

Managing System Files
The switch’s flash memory supports three types of system files that
can be managed by the CLI program, Web interface, or SNMP. The
switch’s file system allows files to be uploaded and downloaded,
copied, deleted, and set as a start-up file.
The three types of files are:
• Configuration — These files store system configuration
information and are created when configuration settings are
saved. Saved configuration files can be selected as a system
start-up file or can be uploaded via TFTP to a server for backup.
A file named “Factory_Default_Config.cfg” contains all the
system default settings and cannot be deleted from the system.
See “Saving or Restoring Configuration Settings” on page 2-28
for more information.
• Operation Code — System software that is executed after
boot-up, also known as run-time code. This code runs the
switch operations and provides the CLI, Web and SNMP
management interfaces. See “Managing Firmware” on page
2-26 for more information.
• Diagnostic Code — Software that is run during system
boot-up, also known as POST (Power On Self-Test). This code
also provides a facility to upload firmware files to the system
directly through the console port. See “Upgrading Firmware via
the Serial Port” on page B-1.
1-13
S
WITCH MANAGEMENT
Due to the size limit of the flash memory, the switch supports only
two operation code files. However, you can have as many
diagnostic code files and configuration files as available flash
memory space allows.
In the system flash memory, one file of each type must be set as
the start-up file. During a system boot, the diagnostic and
operation code files set as the start-up file are run, and then the
start-up configuration file is loaded.
Note that configuration files should be downloaded using a file
namethat reflects the contents or usage of the file settings. If you
download directly to the running-config, the system will reboot,
and the settings will have to be copied from the running-config to
a permanent file.
System Defaults
The switch’s system defaults are provided in the configuration file
“Factory_Default_Config.cfg.” To reset the switch defaults, this file
should be set as the startup configuration file. See “Saving or
Restoring Configuration Settings” on page 2-28.
The following table lists some of the basic system defaults.
