2.6 Making UTP Conne tions
The 10/100/1000 copper ports supports the following connection t pes and distances:
Network Cables
10BASE-T: 2-pair UTP Cat. 3,4,5 , EIA/TIA-568B 100-ohm
100BASE-TX: 2-pair UTP Cat. 5, EIA/TIA-568B 100-ohm
1000BASE-T: 4-pair UTP Cat. 5 or higher (Cat.5e is recommended), EIA/TIA-568B 100-ohm
Link distance: Up to 100 meters
Auto MDI/MDI-X Function
This function allows the port to auto-detect the twisted-pair signals and adapts itself to form a
valid MDI to MDI-X connection with the remote connected device automaticall . No matter a
straight through cable or crossover cable is connected, the ports can sense the receiving pair
automaticall and configure itself to match the rule for MDI to MDI-X connection. It simplifies the
cable installation.
Auto-negotiation Function
The ports are featured with auto-negotiation function and full capabilit to support connection to
an Ethernet devices. The port performs a negotiation process for the speed and duplex
configuration with the connected device automaticall when each time a link is being established. If
the connected device is also auto-negotiation capable, both devices will come out the best
configuration after negotiation process. If the connected device is incapable in auto-negotiation,
the switch will sense the speed and use half duplex for the connection.
Port Configuration Management
For making proper connection to an auto-negotiation incapable device, it is suggested to use port
con- trol function via software management to set forced mode and specif speed and duplex mode
which match the configuration used b the connected device.

13
2.7 Making Fiber Conne tion
The mini-GBIC (SFP) port must be installed with an SFP fiber transceiver for making fiber
connec- tion. Your switch ma come with an SFP transceiver pre-installed when it is shipped.
Installing SFP Fiber Transceiver
To install an SFP fiber transceiver into mini-GBIC port, the steps are:
1. Turn off the power to the switch.
2. Insert the SFP fiber transceiver into the mini-GBIC port. Normall , a bail is provided for ever
SFP transceiver. Hold the bail and make insertion.
3. Until the SFP transceiver is seated securel in the slot, place the bail in lock position.
Connecting Fiber Cables

3. Advan ed Fun tions
To help a better understanding about the software management interfaces, this chapter describes
some advanced functions provided b the switch.
3.1 Abbreviation
Ingress Port : Ingress port is the input port on which a packet is received.
Egress Port : Egress port is the output port from which a packet is sent out.
IEEE 80 .1Q Packets : A packet which is embedded with a VLAN Tag
field
VLAN Tag : In IEEE 802.1Q packet format, 4-b te tag field is inserted in the original Ethernet
frame between the Source Address and T pe/Length fields. The tag is composed of :
#of bits 16 3 1 1
Frame field TPID User priorit CFI VID
TPID : 16-bit field is set to 0x8100 to identif a frame as an IEEE 802.1Q tagged packet
User Priority : 3-bit field refer to the 802.1p priorit
CFI : The Canonical Format Indicator for the MAC address is a 1 bit field.
VID : VLAN identifier, 12-bit field identifies the VLAN to which the frame belongs to.
Untagged packet : A standard Ethernet frame with no VLAN Tag field
Priority-tagged packet : An IEEE 802.1Q packet which VID filed value is zero (VID=0)
VLAN-Tagged packet : An IEEE 802.1Q packet which VID filed value is not zero (VID<>0)
PVID (Port VID)
PVID is the default VID of an ingress port. It is often used in VLAN classification for
untagged packets. It is also often used for egress tagging operation.
DSCP : Differentiated Service Code Point, 6-bit value field in an IP packet
VLAN Table lookup : The process of searching VLAN table to find a VLAN which matches
the given VID index
MAC address table lookup : The process of searching MAC address table to find a MAC
entr which matches the given destination MAC address and the port where the MAC address is
located Packet forwarding : also known as packet switching in a network switch based on
MAC address table and VLAN table information
VLAN forwarding : the operation that a packet is forwarded to an egress destination port based
on
VLAN table information
VLAN group : configuration information about a VLAN which can be recognized in the switch.
The information includes a VID associated to the VLAN, member ports, and some special settings.

16
3.2 QoS Fun tion
The switch provides a powerful Qualit of Service (QoS) function to guide the packet forwarding
in four priorit classes. The versatile classification methods can meet most of the application needs.
The following figure illustrates the QoS operation flow when a packet received on the ingress port
until it is transmitted out from the egress port:

17
3.2.1 Pa ket Priority Classifi ation
Each received packet is examined and classified into one of four priorit classes, Class 3, Class
2, Class 1 and Class 0 upon reception. The switch provides the following classification methods:
80 .1p classification : use User Priorit tag value in the received IEEE 802.1Q packet to map to
one priorit class
DSCP classification : use DSCP value in the received IP packet to map to one priorit class
Port-based classification : used when 802.1p and DSCP are disabled or fail to be applied
The all can be configured to be activated or not. More than one classification methods can be
enabled at the same time. However, 802.1p classification is superior than DSCP classification.
80 .1p mapping tables : Each ingress port has its own mapping table for 802.1p classification.
DSCP mapping table : All ingress ports share one DSCP mapping table for DSCP classification.
Default port priority : A port default priorit class is used when port-based classification is
applied
All configuration settings are in per port basis except that DSCP mapping table is global to all ports. A
received packet is classified into one of four priorit class before it is forwarded to an egress port.
3.2.2 Priority Class Queues
Each egress port in the switch is equipped with four priorit class egress queues to store the
packets for transmission. A packet is stored into the class queue which is associated to the
classified priorit class. For example, a packet is stored into Class 3 egress queue if it is classified
as priorit Class 3.
3.2.3 Egress Servi e Poli y
Each port can be configured with an egress service polic to determine the transmission priorit among
four class queues. B default, higher class number has higher priorit than the lower class
numbers.
Four policies are provided for selection as follows:
 Strict priority : Packets in high priorit class queue are sent first until the queue is empt
 Weighted ratio priority Class 3: :1:0 = 4:3: :1 : four queues are served in 4:3:2:1 ratio
 Weighted ratio priority Class 3: :1:0 = 5:3:1:1 : four queues are served in 5:3:1:1 ratio
 Weighted ratio priority Class 3: :1:0 = 1:1:1:1 : four queues are served equall
Strict priorit polic lets high priorit class queue is served first until it is empt . Lower priorit queue
ma not get an service (or egress bandwidth) when higher priorit traffic is heav for long time. Three
weighted ratio policies are provided to resolve such problem. Four class queues are served in
weighted round robin basis. Ever priorit class can get a guaranteed ratio for the egress
bandwidth.

18
3.3 VLAN Fun tion
The switch supports port-based VLAN, 802.1Q Tag VLAN and eight VLAN groups.
3.3.1 VLAN Operation
The following figure illustrates the basic VLAN operation flow beginning from a packet received on an
ingress port until it is transmitted from an egress port.
The following sections describe the VLAN processes and Advanced VLAN mode settings
provided b the switch. A global setting means the setting is applied to all ports of the switch. A per
port setting means each port can be configured for the setting respectivel .
3.3.2 Ingress Rules
When a packet is received on an ingress port, the ingress rules are applied for packet filtering
and packet tag removal. The related Ingress port settings are:
3.3.2.1 802.1Q Tag Aware Per port setting
Tag-aware -802.1Q Tag Aware mode is used. The switch examines the tag content of ever
received packets. For a VLAN tagged packet, the packet VLAN tag data is
retrieved as packet tag information for VLAN classification and egress tagging
operation. For untagged packet and priorit -tagged packet, port-based mode is used.
Tag-ignore - Port-based mode is used. The switch ignores the tag content of ever received
packets. Ingress Port Default Tag is alwa s used as packet tag information for
VLAN classification.
3.3.2.2 Keep Tag Per port setting
Enable - The VLAN tag in the received VLAN tagged packet will be kept as it is and is
not stripped in whole forwarding operation.
Disable - The VLAN tag data in the received VLAN tagged packet is stripped (removed).

19
3.3.2.3 Drop Untag Per Port Setting
Enable - All untagged packets and priorit -tagged packets are dropped. A priorit -tagged
packet is treated as an untagged packet in this switch. Onl VLAN-tagged packets
are admitted.
Disable - Disable Untagged packet filtering
3.3.2.4 Drop Tag Per Port Setting
Enable - All VLAN-tagged packets are dropped. A priorit -tagged packet is treated as
an untagged packet in this switch. Onl untagged packets are admitted.
Disable - Disable VLAN-tagged packet filtering
3.3.3 Ingress Default Tag Per Port Setting
Each port can be configured with one Ingress Default Tag. This ingress port default tag is used
when ingress port is in Tag-ignore mode or for the received untagged packets in Tag-aware
mode. The Ingress Default Tag includes PVID, CFI and User Priority configuration.
When Ingress port default tag is used, it is copied as packet associated Packet Tag Information for
VLAN classification. The PVID is used as index to one VLAN group in VLAN group table.
3.3.4 Pa ket Tag Information
Under VLAN process, ever packet is associated with one Packet Tag information in packet
forward- ing operation. The tag information includes VID, CFI and User Priorit data and is
used for two purposes:
 The VID in tag is used as index for VLAN classification.
 The tag is used for egress tag insertion if egress tagging is enabled.
The following table lists how the Packet Tag information is generated:
Tag Aware setting Received Packet Type Packet Tag information source
Tag-ignore Untagged packet Ingress Port Default
Tag Tag-ignore Priorit -tagged packet Ingress Port
Default Tag Tag-ignore VLAN-tagged packet Ingress
Port Default Tag Tag-aware Untagged packet
Ingress Port Default Tag Tag-aware Priorit -tagged packet
Ingress Port Default Tag
Tag-aware VLAN-tagged packet Received packet VLAN Tag

20
3.3.5 VLAN Group Table Configuration
The switch provides a table of eight VLAN groups to support up to eight VLANs at the same
time. Each VLAN group is associated to one unique VLAN. The table is referred for VLAN
classification.
A VLAN group contains the following configuration settings:
VID : 12-bit VLAN Identifier index to the VLAN to which the group is associated
Member Ports : the admitted egress ports for packets belonging to this VLAN
Source Port Check : the ingress port of the packet must also be the member port of this
VLAN. Otherwise, the packet is discarded.
3.3.6 VLAN Classifi ation
VLAN classification is a process to classif a VLAN group to which a received packet belongs.
The VID of the generated Packet Tag information associated to the received packet is used as an
index for VLAN group table lookup. The VID matched VLAN group will be used for packet
forwarding. If no matched VLAN group is found in table lookup, the packet is dropped.
Refer to section 3.2.4 for details about how the Packet Tag information is generated.
The member ports specified in the matched VLAN group are the admitted egress port range for
the packet. The packet will never be forwarded to other ports which are not in the member ports.
The Source Port Check setting of the matched VLAN group is also referred. If it is enabled,
the ingress port will be checked whether it is a member port of this group.
3.3.7 Pa ket Forwarding
The forwarding is a process to forward the received packet to one or more egress ports. The
process uses the following information as forwarding decision:
 Member ports of the matched VLAN group : the egress port range for forwarding
 Source Port Check setting of the matched VLAN group : check ingress port membership
 The packet destination MAC address : for MAC address table loop up
 The switch MAC address table : to find the associated port where a MAC address is learned
If the MAC address table lookup is matched and the learned port is the VLAN member port,
the packet is forwarded to the port (egress port). If the lookup failed, the switch will broadcast the
packet to all member ports.
