Configuration Options
For advanced management capability, the TigerSwitch 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.

S
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.

The switch includes an on-board SNMP agent which monitors the
status of its hardware, as well as the traffic passing through its
ports. A computer attached to the network, called a Network
Management Station (NMS), can be used to access this
information. Access rights to the on-board agent are controlled by
community strings. To communicate with the switch, the NMS
must first submit a valid community string for authentication. The

IGMP Multicast Filtering
Multicasting is used to support real-time applications such as video
conferencing or streaming audio. A multicast server does not have
to establish a separate connection with each client. It merely
broadcasts its service to the network, and any hosts which want to
receive the multicast register with their local multicast switch/
router. Although this approach reduces the network overhead
required by a multicast server, the broadcast traffic must be
carefully pruned at every multicast switch/router it passes through
to ensure that traffic is only passed on the hosts which subscribed
to this service.
This switch uses IGMP (Internet Group Management Protocol) to
query for any attached hosts who want to receive a specific
multicast service. The switch looks up the IP Multicast Group used
for this service and adds any port which received a similar request
to that group. It then propagates the service request on to any
neighboring multicast switch/router to ensure that it will continue
to receive the multicast service. (For more information, see “IGMP
Protocol” on page 4-7.)

You can use the VLAN configuration menu to assign any port on

domains. Switches do not inherently support broadcast domains.
This can lead to broadcast storms in large networks that handle
traffic such as IPX or NetBeui. By using IEEE 802.1Q compliant
VLANs, you can organize any group of network nodes into
separate broadcast domains, confining broadcast traffic to the
originating group. This also provides a more secure and cleaner
network environment. For more information on how to use
VLANs, see “Virtual LANs” on page 4-3. The VLAN configuration

802.1Q VLAN Current Table Information
This screen shows the current port members of each VLAN and
whether or not the port supports VLAN tagging. Ports assigned to a
large VLAN group that crosses several switches should use VLAN
tagging. However, if you just want to create a small port-based
VLAN for one or two switches, you can assign ports to the same
untagged VLAN. The current configuration is shown in the

Web-Based Configuration and Monitoring
As well as the menu-driven system configuration program, the
agent module provides an embedded HTTP Web agent. This agent
can be accessed by any computer on the network using a standard
Web browser (Internet Explorer 4.0 or above, or Netscape
Navigator 4.0 or above).
Using the Web browser management interface you can configure a
switch and view statistics to monitor network activity. The Web
interface also provides access to a range of SNMP management
functions with access to the switch’s MIB and RMON database.
Prior to accessing the switch from a Web browser, be sure you
have first performed the following tasks:
1. Configure it with a valid IP address, subnet mask, and default
gateway using an out-of-band serial connection or BOOTP
protocol.
2. Set the Administrator user name and password using an
out-of-band serial connection. Access to the Web agent is
controlled by the same Administrator user name and password
as the on-board configuration program.

sensitive.
Note: Based on the default configuration, a user is allowed three
attempts to enter the correct password; on the third failed
attempt the current connection is terminated. See “Console
