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 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.
All products that are replaced become the property of SMC. Replacement products 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 returned to SMC should have any customer-installed accessory or
add-on 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 [phone].

Connecting to the Switch
Configuration Options
The TigerSwitch 10/100 SMC6750L2 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 1-6.
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.
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,
such as such as SMC’s free EliteView 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.

S WITCH M ANAGEMENT
1-2
The switch’s CLI configuration program, Web interface, and SNMP agent
allow you to perform the following management functions:
• Set user names and passwords for up to 16 users
• Set an IP interface for a management VLAN
• Configure SNMP parameters
• Enable/disable any port
• Set the speed/duplex mode for any port
• Configure up to 255 IEEE 802.1Q VLANs
• Enable GVRP automatic VLAN registration
• Configure IGMP multicast filtering
• TFTP upload and download of system firmware
• TFTP upload and download of switch configuration files
• Configure Spanning Tree parameters
• Configure Class of Service (CoS) priority queuing
• Configure up to six static or LACP trunks
• Enable port mirroring
• Set broadcast storm control on any port
• Display system information and statistics
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.

C ONNECTING TO THE S WITCH
1-3
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 B.
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.
Notes: 1. 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.
2. Refer to “Line Commands” on page 3-56 for a complete
description of console configuration options.

4. Once you have set up the terminal correctly, the console login screen
will be displayed.
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 3-10.
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 1-6.
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 browser (Internet Explorer 5.0 or above, or
Netscape Navigator 6.2 or above), or from a network computer using
network management software such as EliteView.
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, such as EliteView.

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.
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.

S WITCH M ANAGEMENT
1-6
Passwords can consist of up to 8 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>.
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.
Username: admin
Password:
CLI session with the host is opened.
To end the CLI session, enter [Exit].
