“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/smc/pages_html/support.html.

Configuration Options
For advanced management capability, the TigerSwitch 10/100
management agent provides a menu-driven system configuration
program. This program can be accessed by a direct or modem
connection to the serial port on the rear panel (out-of-band), or by
a Telnet connection over the network (in-band).
The management agent is based on SNMP (Simple Network
Management Protocol). This SNMP agent permits the switch to be
managed from any PC in the network using in-band management
software (such as SMC’s EliteView).
The management agent also includes an embedded HTTP Web
agent. This Web agent can be accessed using a standard Web
browser from any computer attached to the network.
1
The system configuration program and the SNMP agent support
management functions such as:
•Enable/disable any port
•Set the communication mode for any port
•Configure SNMP parameters
•Configure VLANs or multicast filtering
•Display system information or statistics
•Configure the switch to join a Spanning Tree
•Download system firmware
•Restart the system

WITCH MANAGEMENT
Required Connections
Console Port (Out-of-Band) Connections
Attach a VT100 compatible terminal or a PC running a terminal
emulation program to the serial port on the switch’s rear panel.
Use the null-modem cable provided with this package, or use a
null modem connection that complies with the wiring assignments
shown in Appendix B of this guide.
When attaching to a PC, set terminal emulation type to VT100,
specify the port used by your PC (i.e., COM 1~4), and then set
communications to 8 data bits, 1 stop bit, no parity, and 19200 bps
(for initial configuration). Also be sure to set flow control to
“none.” (Refer to “Configuring the Serial Port” on page 2-16 for a
complete description of configuration options.)
Note: If the default settings for the management agent’s serial port
have been modified and you are having difficulty making a
console connection, you can display or modify the current
settings using a Web browser as described under “Console
Configuration” on page 3-5.

WITCH MANAGEMENT
Remote Management via the Console Port
Configure the Switch Site
Connect the switch’s DB9 serial port to the modem’s serial port
using standard cabling. For most modems which use a 25-pin port,
you will have to provide an RS-232 cable with a 9-pin connector on
one end and a 25-pin connector on the other end. Set the modem
at the switch’s site to force auto-answer mode. The following is a
sample initialization string: “ATQ 1S0=1&D0&K0&W” as defined
below:
Q1 : Inhibit result codes to DTE
S0=1 : Auto answer on first ring
D0 : Don’t care DTR
K0 : Disables DTE/DCE flow control
W : Write command to modem memory
Configure the Remote Site
At the remote site, connect the PC’s COM port (COM 1~4) to the
modem’s serial port. Set terminal emulation type to VT100, specify
the port used by your PC (i.e., COM 1~4), and then set
communications to 8 data bits, 1 stop bit, no parity, 19200 bps and
no flow control.

WITCH MANAGEMENT
In-Band Connections
Prior to accessing the Network Management Module via a network
connection, you must first configure it with a valid IP address,
subnet mask, and default gateway using an out-of-band
connection or the BOOTP protocol.
After configuring the switch’s IP parameters, you can access the
on-board configuration program from anywhere within the
attached network. The on-board configuration program can be
accessed using Telnet from any computer attached to the network.
The switch and stack can also be managed by any computer using
a Web browser (Internet Explorer 4.0, or Netscape Navigator 4.0 or
above), or from a network computer using network management
software such as EliteView.
Notes: 1. By default BOOTP is disabled. To enable BOOTP, see
“IP Configuration” on page 2-12.
2. Use the Network Configuration menu to specify the
maximum number of simultaneous Telnet sessions that
are supported by the system (up to four).
1-4
3. The on-board program only provides access to basic
configuration functions. To access the full range of
SNMP management functions, you must use SNMPbased network management software, such as SMC’s
free EliteView software.
