User Manual

• TP Port and Cable Installation

⇒ In the switch, TP port supports MDI/MDI-X auto-crossover, so both types of

cable, straight-through (Cable pin-outs for RJ-45 jack 1, 2, 3, 6 to 1, 2, 3, 6 in
10/100M TP; 1, 2, 3, 4, 5, 6, 7, 8 to 1, 2, 3, 4, 5, 6, 7, 8 in Gigabit TP) and
crossed-over (Cable pi n-outs for RJ -45 jack 1, 2, 3, 6 to 3, 6, 1, 2) can be used.
It means you do not have to tell from them, just plug it.

⇒ Use Cat. 5 grade RJ-45 TP cable to connect to a TP port of the switch and the

other end is connected to a network-aware device such as a workstation or a
server.

⇒ Repeat the above steps, as needed, for each RJ-45 port to be connected to a

Gigabit 10/100/1000 TP device.

Now, you can start having the switch in operation.

• Power On

The switch supports 100-240 VAC, 50-60 Hz power supply. The power
supply will automatically convert the local AC power source to DC power. It does not
matter whether any connection plugged into the switch or not when power on, even
modules as well. After the power is on, all LED indicators will light up immediately
and then all off except the power LED still keeps on. This represents a reset of the
system.

• Firmware Loading

After resetting, the bootloader will load the firmware into the memory. It will
take about 30 seconds, after that, the switch will flash all the LED once and
automatically performs self-test and is in ready state.

2-1-3-2. Cabling Requirements for 1000SX/LX SFP Module

It is more complex and comprehensive contrast to TP cabling in the fiber
media. Basically, there are two categories of fiber, multi mode (MM) and single
mode (SM). The later is categorized into several classes by the distance it supports.
They are SX, LX, LHX, XD, and ZX. From the viewpoint of connector type, there
mainly are LC and BIDI LC.

⎯ Gigabit Fiber with multi-mode LC SFP module

⎯ Gigabit Fiber with single-mode LC SFP module

⎯ Gigabit Fiber with BiDi LC 1310nm SFP module

2-1-3-3. Switch Cascading in Topology

• Takes the Delay Time into Account

Theoretically, the switch partitions the collision domain for each port in switch
cascading that you may up-link the switches unlimitedly. In practice, the network
extension (cascading levels & overall diameter) must follow the constraint of the
IEEE 802.3/802.3u/802.3z and other 802.1 series protocol specifications, in which
the limitations are the timing requirement from physical signals defined by 802.3
series specification of Media Access Control (MAC) and PHY, and timer from some
OSI layer 2 protocols such as 802.1d, 802.1q, LACP and so on.

The fiber, TP cables and devices’ bit-time delay (round trip) are as follows:

1000Base-X TP, Fiber 100Base-TX TP

Round trip Delay: 4096 Round trip Delay: 512

Cat. 5 TP Wire: 11.12/m Cat. 5 TP Wire: 1.12/m

Fiber Cable: 10.10/m TP to fiber Converter: 56
Bit Time unit: 1ns (1sec./1000 Mega bit)

Bit Time unit: 0.01μs (1sec./100 Mega bit)

Table 2-2

Sum up all elements’ bit-time delay and the overall bit-time delay of
wires/devices must be within Round Trip Delay (bit times) in a half-duplex network
segment (collision domain). For full-duplex operation, this will not be applied. You
may use the TP-Fiber module to extend the TP node distance over fiber optic and
provide the long haul connection.

⎯ 1000SX Fiber module: Multi-mode up to 220/275/500/550m by fiber type

option

⎯ 1000LX Fiber module: Single-mode up to 10Km
⎯ 1000LHX Fiber module: Single-mode up to 30Km
⎯ 1000ZX Fiber module: Single-mode up to 50Km

• Typical Network Topology in Deployment

A hierarchical network with minimum levels of switch may reduce the timing
delay between server and client station. Basically, with this approach, it will
minimize the number of switches in any one path; will lower the possibility of
network loop and will improve network efficiency. If more than two switches are
connected in the same network, select one switch as Level 1 switch and connect all
other switches to it at Level 2. Server/Host is recommended to connect to the Level
1 switch. This is general if no VLAN or other special requirements are applied.

Case1: All switch ports are in the same local area network. Every port can access

each other (See Fig. 2-3).

Fig. 2-3 No VLAN Configuration Diagram

If VLAN is enabled and configured, each node in the network that can
communicate each other directly is bounded in the same VLAN area.

Here VLAN area is defined by what VLAN you are using. The switch
supports both port-based VLAN and tag-based VLAN. They are different in practical
deployment, especially in physical location. The following diagram shows how it
works and what the difference they are.

Case2a: Port-based VLAN (See Fig.2-4).

1. The same VLAN members could not be in different switches.

2. Every VLAN members could not access VLAN members each other.

3. The switch manager has to assign different names for each VLAN groups
at one switch.

There are two ways to configure and monitor the switch through the switch’s
Ethernet port. They are Web browser and SNMP manager. The user interface for
the last one is NMS dependent and does not cover here. We just introduce the first
type of management interface. Web-based UI for the switch is an interface in a
highly friendly way.

• Managing Web-Smart Switch through Ethernet Port

Before you communicate with the switch, you have to finish first the
configuration of the IP address or to know the IP address of the switch. Then,
follow the procedures listed below.

1. Set up a physical path between the configured the switch and a PC

24 Fast Ethernet + 2 Gigabit Web-Smart Switch
Default IP Setting:
IP = 192.168.1.1
Subnet Mask = 255.255.255.0
Default Gateway = 192.168.1.254

Assign a reasonable IP address,
For example:

Ethernet LAN

IP = 192.168.1.100
Subnet Mask = 255.255.255.0
Default Gateway = 192.168.1.254

by a qualified UTP Cat. 5 cable with RJ-45 connector.

Note: If PC directly connects to the switch, you have to setup the

same subnet mask between them. But, subnet mask may be
different for the PC in the remote site. Please refer to Fig. 2-7 about
the Web-Smart Switch default IP address information.

2. Run web browser and follow the menu. Please refer to Chapter 4.

2-1-5. IP Address Assignment

For IP address configuration, there are three parameters needed to be filled
in. They are IP address, Subnet Mask, Default Gateway and DNS.

IP address:

The address of the network device in the network is used for internetworking
communication. Its address structure looks is shown in the Fig. 2-9. It is “classful”
because it is split into predefined address classes or categories.

Each class has its own network range between the network identifier and
host identifier in the 32 bits address. Each IP address comprises two parts: network
identifier (address) and host identifier (address). The former indicates the network
where the addressed host resides, and the latter indicates the individual host in the
network which the address of host refers to. And the host identifier must be unique
in the same LAN. Here the term of IP address we used is version 4, known as IPv4.

With the classful addressing, it divides IP address into three classes, class A,
class B and class C. The rest of IP addresses are for multicast and broadcast. The
bit length of the network prefix is the same as that of the subnet mask and is
denoted as IP address/X, for example, 192.168.1.0/24. Each class has its address
range described below.

Class A:

Class D and E:

Class D is a class with first 4 MSB (Most significance bit) set to 1-1-1-0 and
is used for IP Multicast. See also RFC 1112. Class E is a class with first 4 MSB set
to 1-1-1-1 and is used for IP broadcast.

According to IANA (Internet Assigned Numbers Authority), there are three
specific IP address blocks reserved and able to be used for extending internal
network. We call it Private IP address and list belo w:

Class A 10.0.0.0 --- 10.255.255.255
Class B 172.16.0.0 --- 172.31.255.255
Class C 192.168.0.0 --- 192.168.255.255

Please refer to RFC 1597 and RFC 1466 for more information.

Subnet mask:

It means the sub-division of a class-based network or a CIDR block. The
subnet is used to determine how to split an IP address to the network prefix and the
host address in bitwise basis. It is designed to utilize IP address more efficiently and
ease to manage IP network.

For a class B network, 128.1.2.3, it may have a subnet mask 255.255.0.0 in
default, in which the first two bytes is with all 1s. This means more than 60
thousands of nodes in flat IP address will be at the same network. It’s too large to
manage practically. Now if we divide it in to smaller network by extending network
prefix from 16 bits to, say 24 bits, that’s using its third byte to subnet this class B
network. Now it has a subnet mask 255.255.255.0, in which each bit of the first
three bytes is 1. It’s now clear that the first two bytes is used to identify the class B
network, the third byte is used to identify the subnet within this class B network and,
of course, the last byte is the host number .

Not all IP address is available in the sub-netted network. Two special
addresses are reserved. They are the addresses with all zero’s and all one’s host
number. For example, an IP address 128.1.2.128, what IP address reserved will be
looked like? All 0s mean t he network itself, and all 1s mean IP broadcast.

In this diagram, you can see the subnet mask with 25-bit long,

255.255.255.128, contains 126 members in the sub-netted network. Another is that
the length of network prefix equals the number of the bit with 1s in that subnet mask.
With this, you can easily count the number of IP addresses matched. The following

Table 2-3

According to the scheme above, a subnet mask 255.255.255.0 will partition a
network with the class C. It means there will have a maximum of 254 effective
nodes existed in this sub-netted network and is considered a physical network in an
autonomous network. So it owns a network IP address which may looks like

168.1.2.0.

With the subnet mask, a bigger network can be cut into small pieces of
network. If we want to have more than two independent networks in a worknet, a
partition to the network must be performed. In this case, subnet mask must be
applied.

User Manual

For different network applications, the subnet mask may look like

255.255.255.240. This means it is a small network accommodating a maximum of
15 nodes in the network.

Default gateway:

For the routed packet, if the destination is not in the routing table, all the
traffic is put into the device with the designated IP address, known as default router.
Basically, it is a routing policy. The gateway setting is used for Trap Events Host
only in the switch.

For assigning an IP address to the switch, you just have to check what the IP
address of the network will be connected with the switch. Use the same network
address and append your host address to it.

supported is half duplex and full duplex. If the media is 1Gbps fiber, it is
1000Mbps supported only. The status of speed/duplex mode is
determined by 1) the negotiation of both local port and link partner in
“Enable” mode or 2) user setting in “Disable” mode. The local port has to
be preset its capability.

Show each port’s flow control status.
There are two types of flow control in Ethernet, Backpressure for half-

duplex operation and Pause flow control (IEEE802.3x) for full-duplex
operation. The switch supports both of them. Default: Enabled

When enabled, traffic can be transmitted and received via this port.
When disabled, the port is blocked and no traffic can be transferred
through this port. Admin function is configurable by the user. There are
only two states “Enable” and “Disable” able to choose. If you set a port’s
state “Disable”, then that port is prohibited to pass any traffic, even it
looks Link up.

Publication date: July, 2006

Revision A2

User Manual

Default is Enable.

Auto Negotiate:

Only “Enable” and “Disable” two states can be chosen. “Enable” means
the port adopted the auto-negotiation algorithm to exchange the
capability with the linked partner and adjusted its speed, duplex and flow
control. When enabled, the speed, duplex mode and flow control mode
may change. “Disable” means the forced mode is adopted. When
disabled, if you want to set up a connection successfully, you must have
both port configuration of local port and linked partner be the same. If
their configuration is different, the link will not be set up successfully. In
the switch, the 1Gbps fiber module, it supports auto and forced modes.

Default: Auto Negotiation is enabled.
Notice: When you are in Disable mode, you must handle it carefully

because this may cause the connection failed.

Speed Duplex:

Set the speed and duplex of the port. In speed, 10/100Mbps baud rate is
available for Fast Ethernet, Gigabit module in port 25, 26. If the media is
1Gbps fiber, it is always 1000Mbps and the duplex is full only. If the
media is TP, the Speed/Duplex is comprised of the combination of speed
mode, 10/100/1000Mbps, and duplex mode, full duplex and half duplex.
The following table summarized the function the media supports.

Media type NWay Speed Duplex

100M TP ON/OFF 10/100M Full/Half
1000M TP ON/OFF 10/100/1000M Full for all, Half for 10/100
1000M Fiber ON/OFF 1000M Full

In Auto-negotiation mode, no default value. In Forced mode, default
value depends on your setting.

Flow Control:

There are two modes to choose in flow control, including Enable and
Disable. If flow control is set Enable, both parties can send PAUSE frame
to the transmitting device(s) if the receiving port is too busy to handle.
When it is set Disable, there will be no flow control in the port. It drops
the packet if too much to handle.

Default: Enable

Default Priority:

Default Priority is used for untagged packets hold QoS priority. It provide
8 priorities (0~7) in each port. When untagged packets enter one port of
the switch, they will have the precedence you set default priority in that
port. For instance, as you choose port 2 with default priority 2 and the
untagged frames get into the port 2 of the switch, they will possess
priority 2 QoS precedence. Then priority 2 packets must check the
setting of QoS function. In default, the priority 2 is in Queue 1. Finally, the
packets will obey the Scheduling Method, Weighted Round Robin or
Strict Priority, to reach QoS effect. Nevertheless, you want Default
Priority to act on, please enable tag–based VLAN in advance.

VIP Port:

VIP Port is particularly used for the “Strict Priority” method of QoS Setting
Scheduling. Please note that you should apply “Strict Priority” Scheduling
Method before the usage of VIP Port.

The function of VIP Port is to offer the highest priority of QoS to the port
you set up. As to the other ports with disabled VIP Port whose priority
cannot be higher than those with enabled VIP Port. For example, if port
2, 3 and 4(Port 2’s VIP Port is enabled) transmit unt agged packets to port
1 at the speed of 100MB and result in the traffic congestion, then the
packets that port 1 had received will be only from port 2. Due to the
priorities of packets coming from port 3, 4 are lower than the ones of VIP
port - port 2, so the packets will form port 3, 4 will be dropped.
Furthermore, this VIP Port capability also cooperates with 802.1p QoS
similarly.

Subnet Mask:

Subnet mask is made for the purpose to get more network address
because any IP device in a network must own its IP address, composed
of Network address and Host address, otherwise can’t communicate with
other devices each other. But unfortunately, the network classes A, B,
and C are all too large to fit for almost all networks, hence, subnet mask
is introduced to solve this problem. Subnet mask uses some bits from
host address and makes an IP address looked Network address, Subnet
mask number and host address. It is shown in the following figure. This
reduces the total IP number of a network able to support, by the amount
of 2 power of the bit number of subnet number (2^(bit number of subnet
number)).

VID y) of port x to tag this packet, the packet then will be forwarded as
the tagged packet with VID y.

Symmetric/Asymmetric:

Forward only packets with VID matching this port’s configured VID. You
can choose “Symmetric” as a way for all ports to filter unwanted traffic. In
Symmetric Mode, a given port checks if the given port is a member of the
VLAN on which the received packet belongs to, to determine forward it or
not. For example, if port 1 receives a tagged packet with VID=100 (VLAN
name=VLAN100), and if “Symmetric/Asymmetric” is Symmetric, the

switch will check if port 1 is a member of VLAN100. If yes, the received
packet is forwarded; otherwise, the received packet is dropped.

Drop Untag Frame:

Drop untagged frame. You can configure a given port to accept all frames
(Tagged and Untagged) or just receive tagged frame. If the former is the
case, then the packets with tagged or untagged will be processed. If the
later is the case, only the packets carrying VLAN tag will be processed,
the rest packets will be discarded.

3-6. Trunking

Trunking configuration is used to configure the settings of Link Aggregation.
You can bundle more than one port with the same speed, full duplex and the same
MAC to be a single logical port, thus the logical port aggregates the bandwidth of
these ports. This means you can apply your current Ethernet equipments to build
the bandwidth aggregation. For example, if there are three Fast Ethernet ports
aggregated in a logical port, then this logical port has bandwidth three times as high
as a single Fast Ethernet port has.

Function name:

Trunking Setting

Function description:

Display the current setup of Aggregation Trunking. With this function, user is
allowed to add a new trunking group or modify the members of an existed
trunking group.

Note:
Check the following to avoid errors in configuration:
When configuring the link aggregation function, you should check that whether

the aggregated ports are in full-duplex mode as well as their speed is the

same or not. The aggregated ports are in the same VLAN group.

Function name:

Mirror Configuration

Function description:

Mirror Configuration is to monitor the traffic of the network. For example, we
assume that Port A and Port B are “Mirror To” Port and “Mirror” Port
respectively, thus, the traffic passed by Port B will be copied to Port A for
monitoring.

Note:
When configuring the mirror function, you should avoid setting a port to be a

sniffer port and aggregated port at the same time. It will cause something
wrong.

Parameter description:

Used for the activation or de-activation of Port Mirror function. Default is
disable.

Monitored Port:

Function name:

QoS Setting

Function description:

The switch offers powerful QoS function. This function supports 802.1p
(Influence the packets with tag or not and when the packets have no tag, the
packets will be added tag according to your Default Priority of Port
Configuration for tagged priority field), VLAN-tagged priority, can make
precedence of 8 priorities and Port-based (VIP port) QoS service. In VLAN­tagged mode, there are 3 bits belonging to this priority in the vlan tagged field.
According to these 3 bits, we could arrange 8 traffic priority (0~7) and
randomly place them into one of 4 Queues that the switch offers. However,
These 4 Queues have different QoS order according to your setting of QoS
Scheduling Method. At present, the switch supports 2 kinds of QoS Scheduling
Method; the one is Weighted Round Robin, the other is Strict Priority. If we had
chosen “Weighted Round Robin” as our Scheduling Method, each Queue will
achieve QoS effect based on its different ratio of bandwidth in Weight. About
VIP Port, when some ports belong to VIP Port, the packets enter VIP port and
they will run in Queue 3 Priority followed by your assigning Weight. But while
you choose Strict Priority Scheduling Method and assign some ports as VIP
Port, VIP port will own the highest priority and get the largest bandwidth
regardless of Queue Priority when the congestion of the network happens.

Parameter description:

Scheduling Method:

Two scheduling methods are offered for QoS, one is Weighted Round
Robin, and the other is Strict Priority. The former will decide the
bandwidth that each Queue will occupy based on the ratio of Weight; the
latter will decide which port owns the highest priority in transmission
according to if the VIP port is enabled or not. Default scheduling method
is Weighted Round Robin.

Priority:

8 kinds of priorities, including 0, 1, 2, 3, 4, 5, 6 and 7.

Queue 0 (Low):

Any priority can be placed into Queue 0. Default priorities are 0 and 1.

Function name:

Isolated Group

Function description:

Isolated Group function can let the port be independent of other ports in the
protected group, and the communication is also forbidden between these ports.
But, the ports of the protected group are still able to communicate with the
ports of the non-protected group. With this design, it will be helpful to the
administrator to immediately find and solve the port that results in the
occurrence of looping problems in the network.

Parameter description:

Protected Group:

User can choose any port to be the member of this group. In this group,
all of these member ports cannot forward packets with each other. Thus,
the switch will not be capable of forwarding any packets in case its all
ports become the members of the protected group.

Not Protected:

The default setting. The port will be set to “Not Protected” while the
network runs normally. “Not Protected” port will be allowed to do packets
forwarding between other ports and to communicate with the ports of the
protected group.
