2. Introduction To 8+2 Gigabit NWay Switch
2.1 General Description
The device is a powerful, high-performance 8+2 10/100/1000Mbps Fast Ethernet and
Gigabit switch, with eight 10/100Mbps ports and two 1000Mbps ports.All ports support auto
MDI-X function and auto-negotiation operation (NWay), which means the switch could
automatically negotiate with the connected partners on the network speed and duplex mode.
The Gigabit copper switching ports are ideal for micro-segmenting large networks into
smaller, connected subnets for improved performance, enabling the bandwidth demanding
multimedia and imaging applications. The Gigabit ports also provide the fat pipe to the
server or backbone connection for boosting the total system performance.
Moreover, the 10/100/1000Mbps auto-sensing ability provides an easy way to migrate
between 10Mbps, 100Mbps or 1000Mbps on networks with no pain. Compared to the
shared 10/100/1000Mbps networks, the switch delivers a dedicated 10/100/1000Mbps
connection to every attached client with no bandwidth congestion issue.
Store-and-forward switching mode promises the low latency plus eliminates all the network
errors, including runt and CRC error packets. To work under full-duplex mode, transmission
and reception of the frames can occur simultaneously without causing collisions as well as
double the network bandwidth.
The switch is plug-n-play without any software to configure and also fully compliant with all
kinds of network protocols. Moreover, the rich diagnostic LEDs on the front-panel can
provide the operating status of individual port and whole system.
For network connection:
The switch can use the following types of cabling:
 10BASE-T: Category 3, 4 or 5 UTP/STP
 100BASE-TX: Category 5 UTP/STP
 1000BASE-T: Category 5 UTP/STP
Category 5 cable is preferred to use with this product in structured wiring
environments. This will ensure correct operation of all ports at 10Mbps, 100Mbps or
1000Mbps.

3.1.3 Installing Network Cables
After placing the switch on the desktop, we need to know how to connect the device
to network.
3.1.3.1 Station Connections with Twisted-Pair Cable
Connect each station to the switch by a category 5 twisted-pair cable
(straight or cross-over cable). Plug one RJ-45 connector into a front-panel
port of the switch, and plug the other RJ-45 connector into the station’s
network adapter.
3.1.3.2 Switch to Switch Connections with Twisted-Pair Cable
In making a switch to switch connection, you could use any port to connect
another switch with straight or cross-over cable.As all ports support auto
MDI-X function, the connection is independent of cable type. Thus, a straight
cable is also allowed to make a switch-to-switch connection.
In order to increase the bandwidth between switch and switch, you could use
the Gigabit ports to connect each other.

4. Switch Operation
4.1 MAC Address Table and Learning
The switch is implemented with a MAC address table where is composed of many entries.
Each entry is used to store the address information of network nodes on the network,
including MAC address, port ID, etc. The information is the most important base to do packet
filtering and forwarding.
When one packet comes in from any port, the switch will learn the source address, port ID,
and the other related information in address table. Therefore, the content of the MAC table
will update dynamically.
4.2 Filtering and Forwarding
When one packet comes in from any port of the switch, it will check the destination address
besides the source address learning. The switch will look up the address table for the
destination address. If not found, this packet will be forwarded to all the other ports except
the port where this packet comes in. If found, and the destination address is located at
different port from this packet comes in, the packet will be forwarded to the port where this
destination address is located according to the information of address table. But, if the
destination address is located at the same port as this packet comes in, this packet will be
filtered.
4.3 Store and Forward
Store-and-forward is one kind of packet-forwarding methodology.As a store-and-forward
switch, it will store the complete packet in the internal buffer and do the complete error
checking before transmitting to the network. Therefore, no error packets will disturb the
network. It is the best choice when a network needs efficiency and stability.

18

VLAN Status/Configuration – Port-based VLAN
This switch provides 10 port-based VLAN groups. Each group can contain 0-10 ports. The
group overlap is allowed.
You can select some ports into the same VLAN group by symbol “V”. If the packets without
the tagging frames come into one port, which only belongs to one VLAN group, the packets
just can be forwarded to another ports of this VLAN group.
For example:
If the VLAN groups is configured as below:
1 2 3 4 5 6 7 8 9
0
VLAN1 [ v v v - - - - - -
- ]
VLAN4 [ v v v
]
VLAN7 [ v v v v
v ]
When one packet without VLAN tag comes into port 1, the packet could be forwarded to
VLAN group:VLAN1,VLAN7. Thus, only port 2,3,7,8,9,0 will receive this packet, and other
ports of this switch will not. On the other hand, if another packet comes into port 6, it will not
be forwarded to any port of this switch because that port 6 does not belong to any VLAN
group.
19

VLAN Status/Configuration – 802.1Q VLAN
This switch provides 10 groups of 802.1Q VLAN function. Each group can contain 0-10 ports.
The group overlap is allowed.
You can select some ports into one VLAN group by symbol “V”. If the packets come into
one port with the same VLAN tag as this coming port’s VLAN ID, the packets just can be
forwarded to another ports of this VLAN group. If the packets come into one port without
VLAN tag, the PVID of this port will be automatically added into the packets as it’s VLAN tag.
In one word, all packets without the same VLAN ID could not be forwarded to other ports.
The “Tagged Port” indicates the aware or unaware VLAN device connected with the port.
For example:
If the VLAN groups is configured as below:
VID Member Port Tagged Port Port PVID
1~4094 -
