1.4 Glossary
10BASE-T
IEEE 802.3 specification for 10 Mbps Ethernet over two pairs of Category 3, 4, or 5 UTP cable.
100BASE-TX
IEEE 802.3u specification for 100 Mbps Fast Ethernet over two pairs of Category 5 UTP cable.
Ethernet
A network communication system developed and standardized by DEC, Intel, and Xerox, using
baseband transmission, CSMA/CD access, logical bus topology, and coaxial cable. The successor
IEEE 802.3 standard provides for integration into the OSI model and extends the physical layer and
media with repeaters and implementations that operate on fiber, thin coax and twisted-pair
cable.
Fast Ethernet
A 100 Mbps network communication system based on Ethernet and the CSMA/CD access method.
Media Access Control (MAC)
A portion of the networking protocol that governs access to the transmission medium, facilitating
the exchange of data between network nodes.
Auto-negotiation
Signalling method allowing each node to select its optimum operational mode (e.g., 10 Mbps or
100 Mbps and half or full duplex) based on the capabilities of the node to which it is connected.
Bandwidth
The difference between the highest and lowest frequencies available for network signals. Also
synonymous with wire speed, the actual speed of the data transmission along the cable.
8
CSMA/CD
Carrier Sense Multiple Access/Collision Detect is the communication method employed by
Ethernet and Fast Ethernet.
Full Duplex
Transmission method that allows switch and network card to transmit and receive concurrently,
effectively doubling the bandwidth of that link.
Port Trunk
Defines a network link aggregation and trunking method which specifies how to create a
single high-speed logical link that combines several lower-speed physical links.
Virtual LAN (VLAN)
A Virtual LAN is a collection of network nodes that share the same collision domain regardless
of their physical location or connection point in the network. A VLAN serves as a logical
workgroup with no physical barriers, and allows users to share information and resources as though
located on the same LAN.
IEEE 802.1Q
VLAN Tagging—Defines Ethernet frame tags which carry VLAN information. It allows
switches to assign endstations to different virtual LANs, and defines a standard way for VLANs to
communicate across switched networks.
IEEE 802.1p
An IEEE standard for providing quality of service (QoS) in Ethernet networks. The standard
uses packet tags that define up to eight traffic classes and allows switches to transmit packets based
on the tagged priority value.
Port Mirroring
A method whereby data on a target port is mirrored to a monitor port for troubleshooting with a
logic analyzer or RMON probe. This allows data on the target port to be studied unobstructively.
Bandwidth Control
This function allows the network manager to control the maximum rate for traffic transmitted
or received on an interface. Rate limiting is configured on interfaces at the edge of a network to
limit traffic into or out of the network. Traffic that falls within the rate limit is transmitted, while
packets that exceed the acceptable amount of traffic are dropped.
9
IGMP Snooping
Listening to IGMP Query and IGMP Report packets transferred between IP Multicast Routers
and IP Multicast host groups to identify IP Multicast group members.
Internet Group Management Protocol (IGMP)
A protocol through which hosts can register with their local router for multicast services. If there
is more than one multicast router on a given subnetwork, one of the routers is made the “querier”
and assumes responsibility for keeping track of group membership.

2.2 Hardware Connection
The power receptacle is located on the rear panel of the switch. The standard power receptacle is
for the AC power cord.
The Switch contains 24 10BASE-T /
100BASE-TX RJ-45 ports. All of these ports
support automatic MDI/MDI-X operation, so you can use straight-through cables for all network
connections to PCs or servers, or to other switches or hubs. Each of these ports also support
auto-negotiation, so the optimum transmission mode (half or full duplex), and data rate (10 or 100
Mbps) can be selected automatically.
See the following section to get more details about connection of RJ-45 ports.
Connecting to PC or Server
You can connect any RJ-45 station port
on the Switch to a PC via twisted-pair cable
with RJ-45 plugs at both ends. Use Category
3, 4 or 5 cable for standard 10Mbps
Ethernet connections, or Category 5 cable
for 100Mbps Fast Ethernet connections.
Make sure you have installed a
10BASE-T or 100BASE-TX network
interface card for connecting a PC to the
Switch’s RJ-45 (MDI-X) station ports. If
LEDs don’t light afterpowering on the Switch, check if the LAN card, the cable and connectors are
properly attached to the PC and the Switch. When a attached PC is powered on or reset:
1. The Link/Act LED will light
2. The FDX/Col LED depends on the installed LAN card’s capabilities for the PC and the Switch
connection.
3. The 100M LED will light for 100Mbps connection, otherwise it will be unlighted.

There are three options in QoS Configuration and two options in priority queue. You can
enable/disable these functions via marking the columns.
TOS/Diff Serv. priority
When you enable this function, the switch can recognize TCP/IP Differentiated Services
Codepoint (DSCP) priority information from the DS-field defined in RFC2474. The DS field
byte for IPv4 is the Type-of-Service (TOS) octet, and for IPv6, it is the Traffic-Class octet. The
recommended DiffServ Codepoints is defined in RFC2597 to classify the traffic into different
service classes. This switch can extract the codepoint value of the DS-field from IPv4 and IPv6
packets, and identify the priority of the incoming IP packet as following definitions:
High priority: whose DS-field = (EF,expected forwarding:) 101110
(AF, Assured Forwarding:) 001010; 010010; 011010; 10001
0
25
(Network Control:) 11x000
Low priority: whose DS-field = others values.
802.1p priority
When 802.1p tag priority is applied, the switch can recognize the 802.1Q VLAN tag frames and
extract the 3-bit User_Priority information from the VLAN tag. The default setting of the
threshold of User_Priority is 3. Therefore, VLAN tagged frames with User_Priority value = 4~7
will be treated as high priority frames, and treat other User_Priority values = 0~3 as low priority
frames.
Adapted Flow Control Ability
The switch can automatically turn off 802.3x flow control and Back pressure flow control for
1~2 seconds whenever the port receives a high priority frames. The flow control is re-enabled
when no priority frames are received for 1~2 seconds.
Priority Weighted Ratio
This switch supports 2 level priority queues. The queue service rate is based on the packet based
Weighted Round Robin algorithm. The packet based service weight ratio of high-priority and
low-priority queuing can be set as 4:1, 8:1, 16:1 or "Always high priority first". The default
setting is 16:1.
Force Set High Priority Port
When Port based priority is applied, any packet received from the a high priority port will be
treated as a high priority frame.
26
3.4.4 VLAN Configuration
This sheet allows you to set the VLANs. This switch supports Port-based and Tag-based
VLANs. Press the Refresh button to read the status of the registers. Press the Add VLAN/Edit
VLAN/Delete VLAN button and select one VLAN in the list box or double-click the VLAN you
want to configure, it will pop up a dialog like following to set the VLAN registers.
27
TAG Control button
Press this button you will see a dialog like following. To configure a port, please double-click
the port you want to configure. There are three types of VLAN Tag Control for you to choose:
1.Remove the VLAN tag from all tagged frame.
2.Insert priority tag into the untagged high-priority frame. (Set priority field = 7, VID field =
0 for high priority frame.)
3.Insert priority tag into the all untagged frame. (Set priority field = 7, VID field = 0 for
high priority frame; Set priority field = 0, VID field = 0 for low priority frame.)
4.Don't touch. (Not modify the packet)
Note: The function could be enabled even the VLAN function is not enabled.
