2.7 Making UTP Connections

The 10/100/1000 RJ-45 copper ports supports the following connection types and dista nces:

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 automatically. No matter a straight
through cable or crossover cable is connected, the ports can sense the receiving pair automatically 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 capability to support connection to any
Ethernet devices. The port performs a negotiation process for the speed and duplex configuration with
the connected device automatically 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 con­trol function via software management to set forced mode and specify speed and duplex mode which
match the configuration used by the connected device.

-13-

2.8 Making Fiber Connection

The SFP slot must be installed with an SFP fiber transceiver for making fiber connection. Your
switch may come with some SFP transceivers pre-installed when it is shipped.

Installing SFP Fiber Transceiver

To install an SFP fiber transceiver into SFP slot, the steps are:

1. Turn off the power to the switch.

2. Insert the SFP fiber transceiver into the SFP slot. Normally, a bail is provided f or every SFP

tra nsce iver. Hold the bail a nd make insertion.

3. Until the SFP transceiver is seated securely in the slot, place the bail in lock position.

Connecting Fiber Cables

LC connectors are commonly equipped on most SFP transceiver modules. Identify TX and RX
connector before making cable connection. The following figure illustrates a connection example
between two fiber ports:

Make sure the Rx-to-Tx connection rule is followed on the both ends of the fiber cable.

Network Cables

3. Advanced Functions

T o help a better understanding about the software management interfa ces, this cha pter describe s some
advanced functions provided by 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 802.1Q Packets : A packet which is embedded with a VLAN Tag field
VLAN T ag : In IEEE 802.1Q packet format, 4-byte tag field is inserted in the original Ethernet frame

between the Source Address and Type/Length fields. The tag is composed of :

#of bits 16 3 1 12

Frame field TPID User priority CFI VID

TPID : 16-bit field is set to 0x8100 to identify a frame as an IEEE 802.1Q tagged packet
User Priority : 3-bit field refer to the 802.1p priority
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 fra me 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 entry

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 Function

The switch provides a powerful Quality of Service (QoS) function to guide the packet forwarding in
four priority 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 Packet Priority Classification

Each received packet is examined and classified into one of four priority classes, Class 3, Class 2,
Class 1 and Class 0 upon reception. The switch provides the following classification methods:

802.1p classification : use User Priority tag value in the received IEEE 802.1Q packet to map to one
priority class

DSCP classification : use DSCP value in the received IP packet to map to one priority class
Port-based classification : used when 802.1p and DSCP are disabled or fail to be applied

They 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.

802.1p 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 priority 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 priority 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 priority class egress queues to store the packets
for transmission. A packet is stored into the class queue which is associated to the classified priority
class. For example, a packet is stored into Class 3 egress queue if it is classified as priority Class 3.

3.2.3 Egress Service Policy

Each port can be configured with an egress service policy to determine the transmission priority among
four class queues. By default, higher class number has higher priority than the lower class numbers.

Four policies are provided for selection as follows:

• Strict priority : Packets in high priority class queue are sent first until the queue is empty

• Weighted ratio priority Class 3:2:1:0 = 4:3:2:1 : four queues are served in 4:3:2:1 ratio

• Weighted ratio priority Class 3:2:1:0 = 5:3:1:1 : four queues are served in 5:3:1:1 ratio

• Weighted ratio priority Class 3:2:1:0 = 1:1:1:1 : four queues are served equally

Strict priority policy lets high priority class queue is served first until it is empty. Lower priority queue
may not get any service (or egress bandwidth) when higher priority traffic is heavy for long time. Three
weighted ratio policies are provided to resolve such problem. Four class queues are served in weighted
round robin basis. Every priority class can get a guaranteed ratio for the egress bandwidth.

-18-

3.3 VLAN Function

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
by 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 respectively.

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 every

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 priority-tagged packet, port-based mode is used.

Tag-ignore - Port-based mode is used. The switch ignores the tag content of every received

packets. Ingress Port Default Tag is always 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 priority-tagged packets are dropped. A priority-tagged packet

is treated as an untagged packet in this switch. Only 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 priority-tagged packet is treated as an

untagged packet in this switch. Only 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 Packet Tag Information

Under VLAN proce ss, every packet is associated with one Packet Tag information in packet forward­ing operation. The tag information includes VID, CFI and User Priority 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 T ag inf ormation is generated:

Tag Aware setting Received Packet Type Packet Tag information source

Tag-ignore Untagged packet Ingress Port Default Tag
Tag-ignore Priority-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 Priority-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 Classification

VLAN classification is a process to classify 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 Packet 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.

-21-

3.3.8 Egress Tagging Rules

Egress Tagging rules are used to make change to the packet before it is stored into egress queue of an
egress port. Three egress settings are provided for each port and are described as follows:

3.3.8.1 Egress Settings

Insert Tag (per port setting)

Enable - Insert the Tag data of the associated Packet Tag information into the packet
Disable - No tagging is performed.

Untagging Specific VID (per port setting)

Enable - No tag insertion if the VID data of the associated Packet Tag information matches the

Untagged VID configured in next setting even [Insert Tag] is enabled.

Disable - This rule is not applied.

3.4 802.1X Authentication

For some IEEE 802 LAN environments, it is desirable to restrict access to the services offered by the
LAN to those users and devices that are permitted to make use of those services. IEEE 802.1X Port­based network access control function provide a means of authenticating and authorizing devices at­tached to a LAN port that has point-to-point connection chara cteristics, a nd of preventing a ccess to that
port in cases in which the authentication and authorization process fails. The 802.1X sta ndard relie s on
the client to provide credentials in order to gain a ccess to the network. The credenti als are not based on
a hardware addre ss. Instead, they ca n be e ither a username/password combination or a certificate. The
credentials are not verified by the switch but are sent to a Remote Authentication Dial-In User Service
(RADIUS) server, which maintains a data ba se of authentication information. 802.1X consists of three
components for authentication excha nge, which are as follows:

-22-

 An 802.1X authenticator: This is the port on the switch that has services to offer to an end device,
provided the device supplies the proper credentials.
 An 802.1X supplicant: This is the end device; for example, a PC that connects to a switch that is
requesting to use the services (port) of the device. The 802.1X supplicant must be able to respond to
communicate.
 An 802.1X authentication server: This is a RADIUS server that examines the credentials provided to
the authenticator from the supplica nt a nd provides the authentication service. The authentication server is respon­sible for letting the authenticator know if services should be granted.

The 802.1X authenticator operates as a go-between with the supplicant and the authentication server to
provide services to the network. When a switch is configured as an authenticator, the ports of the
switch must then be configured for authorization. In a n authenticator-initi ated port authorization, a client
is powered up or plugs into the port, and the authenticator port sends an Extensible Authentication
Protocol (EAP) PDU to the supplica nt requesting the identification of the supplica nt. At this point in the
process, the port on the switch is connected from a physical standpoint; however, the 802.1X process
has not authorized the port and no frames are pa ssed from the port on the supplicant into the switching
engine. If the PC attached to the switch did not understand the EAP PDU that it wa s receiving from the
switch, it would not be able to send a n ID and the port would remain unauthorized. In this state, the port
would never pass any user traffic and would be as good as disabled. If the client PC is running the

802.1X EAP, it would respond to the request with its configured ID. (This could be a username/
password combination or a certificate.)

After the switch, the authenticator receives the ID from the PC (the supplicant). The switch then
passes the ID information to an authentication server (RADIUS server) that can verify the identifica­tion information. The RADIUS server responds to the switch with either a success or failure message.
If the response is a success, the port will be authorized and user traffic will be allowed to pass through
the port like any switch port connected to an access device. If the response is a failure, the port will
remain unauthorized and, therefore, unused. If there is no response from the server, the port will also
remain unauthorized a nd will not pa ss any traffic.

4.4.1 Management VLAN

Management VLAN settings allow administrator to access the switch and perform the switch ma nage­ment over a dedicated VLAN.

The following rules are a pplied with the M anagement VLAN:

1. If the VLAN function is disabled, Management VLAN settings are ignored and no VLAN

limitation is a pplied in accessing the switch web ma nagement interface. The switch web (http)
server only accepts untagged management packets and replies untagged packets to the manage­ment host.

2. If [Management VLAN - VID] settings is zero, no VLAN limitation is applied in accessing the

switch web management interface. The switch web (http) server only accepts untagged manage­ment packets and replies untagged packets to the management host.

3. If [Management VLAN - VID] settings is not zero, The switch web (http) server only accepts

tagged management packets matched [Management VLAN -VID] and replies tagged packets
with tag composed of [Management VLAN] VID, CFI and User Priority settings to the manage­ment host. The egress port will also be limited in the member ports of the matched VLAN group.

Summary of the rules:

VLAN Function Management VID Switch Embedded Web Server operation

VLAN disabled Ignore Accept untagged web packets

Reply untagged packets
No VLAN group member checking

VLAN enabled VID=0 Accept untagged web packets

Reply untagged packets
No VLAN group member checking

VLAN enabled VID<>0 Accept matched tagged web packets only

( 1 ~ 4095) Reply tagged packets with the configured tag

Matched VLAN group member checking

Notes:

1. To apply management VLAN function, be sure to configure a VLAN group that matches the

management VID first.

2. No matter how management VLAN is configured, login password authentication is still

required.

4.6.4 Important Notes for VLAN Configuration

Some considerations should be checked in configuring VLAN settings:

1. Switch VLAN Mode selection

It is suggested to evaluate your VLAN application first and plan your VLAN configuration
carefully before applying it. Any incorrect setting might cause network problem.

2. Aggregation/Trunking configuration

Make sure the members of a link aggregation (trunk) group are configured with same VLAN
configuration and are in same VLAN group.

3. Double Tagged in Advanced VLAN Mode

For a received packet, Ingress port [Keep Tag] setting and Egress port [Insert Tag] setting are
enabled at the same time. It will cause the packet double-tagged when egress. Although, it is
often applied in Q-in-Q provider bridging a pplication. However, such condition should be avoided
in normal VLAN configuration. See table below:

Ingress port Egress port

4. The ports configured in non-LACP aggregation are not available in this configuration.

-42-

4.9 RSTP

Configuration Description

System Priority The lower the bridge priority is the higher priority it has. Usually , the bridge

with the highest bridge priority is the root. Value: 0 ~ 61440

Hello Ti me Hello Time is used to determine the periodic time to send normal BPDU

from designated ports among bridge s. It decides how long a bridge should
send this message to other bridge to tell I am alive.

Max Age When the switch is the root bridge, the whole LAN will apply this setting

as the ir maximum age ti me.

Forward Delay This figure is set by Root Bridge only. The forward delay time is defined as

the time spent from Listening state moved to Learning state and also from
Learning state moved to Forwarding state of a port in bridge.

Force Version Two options are offered for choosing STP algorithm.

Compatible - STP (IEEE 802.1D)
Normal - RSTP (IEEE 802.1w)

-43-

Aggregations Enabled to support port trunking in STP. It means a link aggregate is

treated as a physical port in RSTP/STP operation.
Port Protocol Enabled Port is enabled to support RSTP/STP.
Port Edge An Edge Port is a port connected to a device that knows nothing about

STP or RSTP. Usually, the connected device is an end station. Edge Ports

will immedi ately tra nsit to forwarding state and skip the listening and

learning state because the edge ports cannot create bridging loops in the

network.
Port Path Cost Specifies the path cost of the port that switch uses to determine which port

are the forwarding ports the lowest number is forwarding ports, the rage is

1 ~ 200,000,000 and Auto. Auto means a default cost is automatically

calculated in RSTP operation ba sed on the port link speed.

The default costs are :

Note:

802.1p classification is superior over DSCP classification if both are enabled. That means if a
received packet is classified successfully in 802.1p classification, the classified priority class is
used directly for the packet and the result of DSCP classification is ignored.

4.12.2 DSCP Mapping

Configuration Description

DSCP [0-63] Seven user-defined DSCP values which are configured with a priority class

0 ~ 63 - 6-bit DSCP value in decimal

Priority The priority class configured for the user-defined DSCP value

Class 3 ~ Class 0

All others The other DSCP values not in the seven user-defined values are assigned a

default priority class

Class 3 ~ Class 0

4.12.3 QoS Service Policy

Configuration Description

Port Port number
Policy Service policy for egress priority a mong f our egress class queues

Strict priority - high class queue is served first always till it is empty
Weighted ratio priority Class 3:2:1:0 = 4:3:2:1 - weighted ratio 4:3:2:1
Weighted ratio priority Class 3:2:1:0 = 5:3:1:1 - weighted ratio 5:3:1:1
Weighted ratio priority Class 3:2:1:0 = 1:1:1:1 - weighted ratio 1:1:1:1

[Apply] Click to apply the configuration cha nge
[Refresh] Click to refresh current configuration
[Back] Click to go back to upper menu

Notes:

1. Queue with higher class number has higher priority than queue with lower class number.

That means Class 3 > Class 2 > Class 1 > Class 0 by default.

2. In weighted ratio policies, a weighted fairness round robin service is guaranteed normally.

However, when excess bandwidth exists higher class queue will take advantage on band­width allocation.
