Configuration Options

For advanced management capability, the TigerSwitch 1000
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
managem ent fu nc tions such as:

• Enable/disable any port

• Set the communication mode for any port

• Configure SNMP parameters

• Display system information or statistics

• Configure the switch to join a Spanning Tree

• Download system firmware

• Restart the system

WITCH MANAGE MENT

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 2-14 for a
complete description of configuration options.)

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 RS232 cable with a 9-pin connector on
one end an d a 25- pin conn ector on the o ther end. S et th e modem
at the switch’s site to force auto-answer mode. The following is a
sample initialization string: “ATQ1S0=1&D0&K0&W” as defined
bel o w:

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

S

WITCH MANAGEMENT

Configure the Re mote 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.

In-Band Connections

Prior to accessing the management agent 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.

Note: By default BOOTP is disabled. To enable BOOTP, see “IP

Configuration” on page 2-11.

Telnet Connect ion

Prior to accessing the management agent via an in-band Telnet
connection, you must first configure it with a valid IP address,
subnet mask, and default gateway using an out-of-band
connection or BOOTP protocol. After configuring the switch’s IP
parameters, you can access the on-board configuration program
from anywhere within the attached network.

Note: Use the Network Configuration menu to specify the

maximum number of simultaneous Telnet sessions that are
supported by the system (up to four).

In-Band Network Connection

The on-board 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 4.0 or above, or Netscape Navigator 4.0 or above), or
from a network computer using network management software
such as EliteView.

Note: The on-board 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 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

Using the Spanning Tree Algorithm

The Spanning Tree Algorithm can be used to detect and disable
network loops, and to provide backup links between switches,
bridges or routers. This allows the switch to interact with other
bridging devices (that is, an STA-compliant switch, bridge or
router) in your network to ensure that only one route exists
between any two stations on the network. For a more detailed
description of how to use this algorithm, refer to “Spanning Tree

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
Snooping and IP Multicast Filtering” on page 4-6.)

Configuring Virtual LANs

You can use the VLAN configuration menu to assign any port on
the switch to any of up to 16 LAN groups. In conventional
networks with routers, broadcast traffic is split up into separate
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, yo u can organize any gr ou p of network nodes into
separate broadcast domains, confining broadcast traffic to the
originating group. This also provides a more secure and cleaner
net work environment . For more infor mation on h ow to us e

Web-Based Configuration and Monitoring

As well as the menu-driven system configuration program, the
switch 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
fun c tions with i ts MIB and RMON br owser uti li ties.

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
protoc ol.

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.

Security Configuration

Use the Security Configuration screen to restrict m anagement
access based on a specified password. The Administrator has write
access for parameters governing the SNMP agent. You should
therefore assign a password to the Administrator as soon as
possible, and store it in a safe place. (If for some reason your
password is lost, or you cannot gain access to the system’s
configuration program, contact your SMC distributor for
assistance.)

Change Password

This password is for the system Administrator, with access
privilege of Read/Write for all screens. Passwords can consist of up
to 15 alphanumeric characters and are not case sensitive. (User
name: admin ; default passw or d: null.)

Firmware Upgrade Options

You can upgrade system firmware via a Web browser, a TFTP
server, or a direct connection to the console port.

Web Upload Management

Use the Web Upload Management m enu to load software updates
into the switch. The upload file should be an SMC8608SX binary
file from SMC; otherwise the agent will not accept it. The success
of the upload operation depends on the quality of the network
connection. After uploading the new software, the agent will
automatically restart itself. Parameters shown on this screen are

Address Table Configuration

The Address Table contains the unicast MAC addresses and VLAN
identifier associated with each port (that is, the source port
associated with the address and VLAN), sorted by MAC address or
VLAN. You can also clear the entire address table, or information
associated with a specific address; or set the aging time for
deleting inactive entries. The information displayed in the Address

STA (Spanning Tree Algorithm)

The Spanning Tree Algorithm can be used to detect and disable
network loops, and to provide backup links between switches,
bridges or routers. This allows the switch to interact with other
bridging devices (that is, STA compliant switch, bridge or router)
in your network to ensure that only one route exists between any
two sta tions on the net work. For a more detail ed desc ri p tion of
how to use this algorithm, refer to “Spanning Tree Algorithm” on
page 4-1.

Spanning T ree Information

The Spanning Tree Information screen displays a summary of the
STA information for the overall bridge or for a specific port. To
make any changes to the parameters for the Spanning Tree, use
the Spanning Tree Configuration menu.
