1. INTRODUCTION
Thank you for using the 5-Port 10/100TX plus 1-Port 100FX Uplink & 6-Port 10/100Base-TX
Fast Ethernet Smart Switch. The built-in management module allows users to configure this
Smart Switch and monitor the operation status locally or remotely through network.
The Smart Switch is fully compliant with IEEE 802.3 and 802.3u standards. By employing
store and forward switching mechanism, the Smart Switch provides low latency and faster
data transmission. Moreover, it also supports more advanced functions such as QoS, Q-in-Q
VLAN Tunneling, Rate Limiting, IGMP Snooping, etc. Users can configure the required
settings of the Smart Switch and monitor its real-time operational status via Command Line
Interface and Web Management. For detailed description on both management methods,
please refer to Section 2 and 3 respectively.
1.1 Interfaces
The Smart Switch Series provides two models with different interfaces. Depending on your
networking requirements, you can select the most suitable one to apply in your networking
environment. Figure 1 below displays the interface with five 10/100 LAN ports; whereas,
Figure 2 shows one WAN TP and five 10/100 LAN ports.
Figure 1. 5 10/100 LAN Ports
Figure 2. 1 WAN TP Port & 5 10/100 LAN Ports
Both models have the same top panel that displays LED indicators for each LAN connection
and link status.
Figure 3. Top Panel with LED Indicators

1.2 Management Preparations
The Smart Switch can be accessed through Telnet connection or a web browser, such as
Internet Explorer or Netscape, etc. Before you can access to the Smart Switch to configure it,
you need to connect cables properly.
Connecting the Smart Switch
It is extremely important that proper cables are used with correct pin arrangements when
connecting Smart Switch to other devices such as switches, hubs, workstations, etc.
100Base-FX Fiber Port
1x100Base-FX fiber port is located inside the Smart Switch. This port is primarily
used for up-link connection and will operate at 100M/Full or Half Duplex mode.
Duplex SC or WDM Simplex SC types of connectors are available. Use proper
multimode or single-mode optical fiber to connect this port with the other Fast
Ethernet Fiber port.
Before connecting to other switches, workstation or media converter, make sure both
sides of the fiber transfer are with the same media type, for example 100Base-FX
Single-mode to 100Base-FX Single-mode, 100Bas-FX Multimode to 100Base-FX
Multimode. And check that the fiber-optic cable type matches the fiber transfer model.
To connect to 100Base-FX transfer, use the multi-mode fiber cable (one side must be
male duplex SC connector type). To connect to 100Base-FX transfer, use the singlemode fiber cable (one side must be male duplex SC connector type).
10/100Base-TX RJ-45 Ports
5 or 6 10/100Base-TX RJ-45 ports are located on the front panel of the Smart Switch
depending on the model that you purchased. These RJ-45 ports allow users to
connect their traditional copper based Ethernet/Fast Ethernet devices into network.
All these ports support auto-negotiation and MDI/MDIX auto-crossover, i.e. either
crossover or straight through CAT-5 cable may be used.
Assigning IP Addresses
IP addresses have the format n.n.n.n, for example 168.168.8.100.
IP addresses are made up of two parts:
The first part (168.168.XXX.XXX in the example) refers as network address identifies
the network on which the device resides. Network addresses are assigned by three
allocation organizations. Depending on your location, each allocation organization
assigns a globally unique network number to each network that wishes to connect to
the Internet.
8
The second part (XXX.XXX.8.100 in the example) identifies the device within the
network. Assigning unique device numbers is your responsibility. If you are unsure of
the IP addresses allocated to you, consult the allocation organization from which your
IP addresses were obtained.
Remember that no two devices on a network can have the same address. If you connect to
the outside, you must change all the arbitrary IP addresses to comply with those you have
been allocated by the allocation organization. If you do not do this, your outside
communications will not operate.
A subnet mask is a filtering system for IP addresses. It allows you to further subdivide your
network. You must use the proper subnet mask for proper operation of a network with
subnets defined.

2. Command Line Interface (CLI)
This chapter introduces you how to use Command Line Interface (CLI) via Telnet connection,
specifically in:
Configuring the system
Resetting the system
Upgrading newly released firmware
2.1 Remote Console Management-Telnet
You can use Command Line Interface to manage the Smart Switch via Telnet session. For
first-time users, you must first assign a unique IP address to the Smart Switch before you
can manage it remotely. Use any one of the RJ-45 ports on the front panel as the temporary
management console port to login to the Smart Switch with the default username &
password and then assign the IP address using IP command in Global Configuration mode.
Follow steps described below to access the Smart Switch through Telnet session:
Step 1. Use any one of the RJ-45 ports as a temporary management console port to
login to the Smart Switch.
Step 2. Run Telnet client and connect to 192.168.0.1. For first-time users, make sure
the IP address of your PC or workstation is assigned to an IP address between
192.168.0.2 and 192.168.0.254 with subnet mask 255.255.255.0.
Step 3. When asked for a username, enter “admin”. When asked for a password,
leave the password field blank and press Enter (by default, no password is
required.)
Step 5. If you enter CLI successfully, the prompt display Switch> (the model name of
your device together with a greater than sign) will appear on the screen.
Step 6. Set up the Smart Switch‟s IP address, subnet mask and the default gateway
using “IP” command in Global Configuration mode.
Step 7. Once you enter new IP address for the Smart Switch, the telnet session will be
terminated immediately. Use your new IP address to login to the Smart Switch
via Telnet session.
Limitation: Only one active Telnet session can access the Smart Switch at a time.
10
2.2 Navigating CLI
When you successfully access the Smart Switch, you will be asked for a login username.
Enter your authorized username and password, and then you will be directed to User mode.
In CLI management, the User mode only provides users basic functions to operate the
Smart Switch. If you would like to configure advanced features of the Smart Switch, such as,
VLAN, QoS, Rate limit control, you must enter the Configuration mode. The following table
provides an overview of modes available in this Smart Switch.
Command Mode

NOTE: By default, the model name will be used for the prompt display. You can change
the prompt display to the one that is ideal for your network environment using the
hostname command. However, for convenience, the prompt display “Switch” will be used
throughout this user’s manual.
2.2.1 General Commands

four ways to enter your interface numbers to signify the combination of different interfaces
that apply to a command or commands.
Commands
Description
Switch(config)# interface 1
Switch(config-if)#
Enter a single interface. Only interface 1 will
apply to commands entered.
Switch(config)# interface 1,3,5
Switch(config-if)#
Enter three discontinuous interfaces,
separating by a comma. Interface 1, 3, 5 will
apply to commands entered.
Switch(config)# interface 1-3
Switch(config-if)#
Enter three continuous interfaces. Use a
hyphen to signify a range of interface
numbers. In this example, interface 1, 2, and
3 will apply to commands entered.
Switch(config)# interface 1,3-5
Switch(config-if)#
Enter a single interface number together with
a range of interface numbers. Use both
comma and hyphen to signify the
combination of different interface numbers.
In this example, interface 1, 3, 4, 5 will apply
to commands entered.
The “interface” command can be used together with “QoS” and “VLAN” commands. For
detailed usages, please refer to QoS and VLAN section below.
2.5.2 No command
Almost commands that you enter in Configuration mode can be negated using “no”
command followed by the original command. The purpose of “no” command is to disable a
function, remove a command, or set the setting back to the default value. In each subsection below, the use of no command to fulfill different purposes will be introduced.
2.5.3 Show command

3. Enable or disable IGMP snooping globally.
IGMP, Internet Group Management Protocol, is a communications protocol used to manage
the membership of Internet Protocol multicast groups. IGMP is used by IP hosts and
adjacent multicast routers to establish multicast group memberships. It can be used for
online streaming video and gaming, and allows more efficient use of resources when
supporting these uses.
IGMP Snooping is the process of listening to IGMP traffic. IGMP snooping, as implied by the
name, is a feature that allows the switch to "listen in" on the IGMP conversation between
hosts and routers by processing the layer 3 packets IGMP packets sent in a multicast
network.
When IGMP snooping is enabled in a switch it analyses all the IGMP packets between hosts
connected to the switch and multicast routers in the network. When a switch hears an IGMP
report from a host for a given multicast group, the switch adds the host's port number to the
multicast list for that group. And, when the switch hears an IGMP Leave, it removes the
host's port from the table entry.
IGMP snooping can very effectively reduce multicast traffic from streaming and other
bandwidth intensive IP applications. A switch using IGMP snooping will only forward
multicast traffic to the hosts interested in that traffic. This reduction of multicast traffic
reduces the packet processing at the switch (at the cost of needing additional memory to
handle the multicast tables) and also reduces the workload at the end hosts since their
network cards (or operating system) will not have to receive and filter all the multicast traffic
generated in the network.
Command / Example
Description
Switch(config)# ip igmp snooping
Enable IGMP snooping function.
No command
Switch(config)# no ip igmp snooping
Disable IGMP snooping function.
Show command
Switch(config)# show ip igmp snooping

groups
Show IGMP group table. When IGMP
Snooping is enabled, the Smart Switch is
able to read multicast group IP and the
corresponding MAC address from IGMP
packets that enter the device.
21
4. Enable IGMP snooping immediate-leave function. This works only when IGMP Snooping
is enabled. When Immediate Leave is enabled, the Smart Switch immediately removes the
port when it detects IGMPv1 & IGMPv2 leave message on that port.
Command / Example
Description
Switch(config)# ip igmp snooping
immediate-leave
Enable IGMP immediate leave function.
No command
Switch(config)# no ip igmp snooping
