3. Making Connections and Configuring IP Address

3.1 Making UTP Connections

The 10/100 and 10/100/1000 RJ-45 copper ports support the following connection types 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 automatically. No matter a straight through cable or

crossover cable are connected, the ports can sense the receiving pair automatically and configure themselves 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.

-18-

3.2 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 for every SFP transceiver.

Hold the bail and make insertion.

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

-19-

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

Multimode (MMF) - 50/125Pm, 62.5/125Pm

Single mode (SMF) - 9/125Pm

Fiber Port Configuration

For 1000M fiber application on Port 25 and Port 26, just leave the default port configuration Auto for fiber

connection.

Remark:

1. In Tag-based VLAN, a received packet is forwarded to egress ports based on the rules below:

Packet type received on an ingress port Forwarding Rule to a VLAN

Untagged packet

Use ingress port’s default VLAN index pointing to the

VLAN group to be used

Priority-tagged packet (VID=0)

Use ingress port’s default VLAN index pointing to the

VLAN group to be used

Tagged packet

Use the embedded VID in tag data of the packet to find a

matched VLAN group within VLAN Group1 ~ Group32

2. The default member ports and VID of all 32 VLAN groups are displayed as follows:

-40-

Note:

For the Tag-based mode, the ingress port of a received packet must be the member port of the matched VLAN.

Otherwise, the packet is dropped. If any VLAN uplink ports are set, the packet is forwarded to the unlink ports

instead. Refer to Section “Miscellaneous-> VLAN Uplink” for more details.

-41-

4.14 Multi to 1 VLAN Setting

Configuration Description

Joint port Select a port as the joint port

[Apply] Click to apply the configuration change

[LoadDefault] Click to use default setting values

Remark:

1. This mode is a special port-based VLAN application. Each of all ports combing the joint port becomes an

individual 2-port VLAN group logically. The joint port is the common port for all groups.

2. Each of all ports except the joint port can only forward packets to the joint port.

3. The point port can forward packets to all ports except itself.

4. All ports can’t talk to each other except the joint port.

Note:

To click [Apply] will change VLAN mode to port-based VLAN and configure according settings. The previous

egress rule settings are set to defaults.

4.15 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. Members of a Tagged-based VLAN Group

For Tag-based mode, the ingress port of a received packet must be the member port of the matched VLAN.

Otherwise, the packet is dropped.

3. Link Aggregation/Trunking configuration

Make sure all members of one link aggregation (trunk) group are configured with same VLAN

configuration and are in same VLAN group.

-43-

4.16 QoS Priority Mode

Configuration Description

Mode QoS service policy for egress operation on a port

First-In-First-Out – egress by packet arrival time, no priority difference

All-High-before-Low – all high priority packets transmitted first

Weight-Round-Robin – egress based on [High / Low] weight ratio

Low weight Weight of low priority in weight ratio

0 ~ 7 (weight 0 = weight 8)

High weight Weight of high priority in weight ratio

0 ~ 7 (weight 0 = weight 8)

[Apply] Click to apply the configuration change

Remark:

1. The switch implements two levels of priority queues for port egress operation.

2. Each packet is classified as high priority or low priority based on CoS classification configuration.

3. Weight value 0 represents “8” actually.

-44-

4.17 Priority Classification - Port, 802.1p, IP/DS Based

Configuration Description

Enable High Priority v – set to enable high priority classification

Port No. Port number for QoS classification in ingress

Port Base v – set to enable the port as high priority port

All packets received by a high priority port are classified as high priority packets.

802.1p v – set to enable 802.1p-based priority classification scheme

802.1Q tagged packet is examined the TCI (Tag Control Information, 16 bits) field of

the 802.1Q tag data.

-45-

The classification rule is:

Bit[15:13] Priority field in TCI data 000 ~ 011: low priority

100 ~111: high priority

IP/DS v – set to enable IP-based priority classification scheme

IPv4 packet is examined the TOS (Type of Service, 6 bits) data and IPv6 packet is

examined the Traffic Class (6 bits) data. The classification rule is:

101110, 001010, 010010, 011010, 100010, 11x000: high priority

Others: Low priority

[Apply] Click to apply the configuration change

Remark:

1. Each incoming packet is classified as high or low priority based on classification configuration of the

ingress port.

2. When multiple schemes are applied, a received packet is treated as the high priority as long as any one of

the enabled schemes classifies it as high priority.

-46-

4.18 Priority Classification – TCP/UDP Port Based

highest bridge priority is the root.

0 ~ 61440

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

designated ports among bridges. It decides how long a bridge should send this

message to other bridge to tell I am alive.

1 ~ 10 seconds

Max Age When the switch is root bridge, the whole LAN uses this setting as the maximum age

time.

6 ~ 40 seconds

Forward Delay This figure is set at Root Bridge only.

[Apply] Click to apply the configuration.

-53-

Status Description

Bridge ID “Priority:MAC address” ID of current STP bridge

Hello Time Current Hello Time

Max Age The maximum age time

Forward Delay This figure is set at 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.

Root ID The MAC address of current STP root

If this switch is STP root, a message of “I’m the root bridge!” is displayed.

Note:

STP support and MAC Address Binding function are exclusive. Two functions can not be enabled at the same

time..

4.22 STP Port Settings

RPC Specifies the path cost of the port that switch uses to determine which port are the

forwarding ports the lowest number is forwarding ports.

Value: 1 ~ 200,000,000

0 = Auto

Auto means a default cost is automatically calculated in RSTP operation based on the

port link speed. The default costs are:

Link Speed

10Mbps 2000000

100Mbps 200000

1000Mbps 20000

[Apply] Click to apply the configuration.

Auto Default Cost

-55-

Status Description

Port No. Port

RPC Path cost of the p

Priority Port priority

State Root Port – A forwarding port that is the best port from Nonroot-bridge to Root

bridge

Designated Port – A forwarding port for every LAN segment

Alternate – An alternate path to the root bridge. This path is different than using the

root port.

Back Up - A backup/redundant path to a segment where another bridge port already

connects.

Status Forwarding – A port receiving and sending data, normal operation. STP still

monitors incoming BPDUs that would indicate it should return to the blocking state

to prevent a loop.

Blocking - A port that would cause a switching loop, no user data is sent or received

but it may go into forwarding mode if the other links in use were to fail and the

spanning tree algorithm determines the port may transition to the forwarding state.

BPDU data is still received in blocking state.

Listening - The switch processes BPDUs and awaits possible new information that

would cause it to return to the blocking state.

Learning - While the port does not yet forward frames (packets) it does learn source

addresses from frames received and adds them to the filtering database (switching

database)

Designated Bridge ID of the STP gridge who designated the root port

Designated Port Port number of the bridge from where the bridge designated the root port

[Refresh] Click to refresh current configuration

[Apply] Click to apply the configuration change

Link aggregation function allows making connection between two switches using more than one physical links.

It can increase the connection bandwidth between two switches. The switch supports up to three trunk groups

and the number of member ports belonging to one trunk group is limited and must be more than two.

Notes:

1. All member ports of one trunk group must belong to same VLAN group and have same VLAN configuration

settings. Otherwise, abnormal operation might be experienced.

An enabled port for MAC address binding is not allowed to be member port of any trunk group.

4.24 Miscellaneous Settings

Configuration Description

Packet Aging Time in Queues Option: Disable, 200ms, 400ms, 600ms, 800ms

VLAN Striding Option: Disable, Enable

IGMP Snooping Option: Disable, Enable

Uplink1 VLAN uplink 1, options:

Clear, Port 1, Port 2, ….., Port 26

Uplink2 VLAN uplink 2, Option:

Clear, Port 1, Port 2, ….., Port 26

[Apply] Click to apply the configuration change

-59-

Remark:

1. A packet is dropped if the time it stays in output queue is more than the configured Aging time. “Disable”

setting forces a packet never aged out.

2. VLAN Striding

In normal case, a uni-cast packet is not allowed to be forwarded to a port not in a VLAN member port list

and the uni-cast is dropped. “Enable” VLAN Striding allows the uni-cast packet to be forwarded cross a

VLAN. That means uni-cast packets are forwarded as no VLAN limitation.

3. IGMP Snooping

When this function is enabled, the switch will monitor multicast router ports and maintain IP multicast

group information. The switch also listens on IGMP messages to maintain the associated member ports of

each multicast group. Multicast packets are forwarded only to the group’s member ports. The ports not in

the member list are not affected by the multicast traffic.

4. VLAN Uplink Ports

With VLAN uplink enabled, a packet which is filtered in a VLAN is forwarded to VLAN uplink ports instead.

The VLAN uplink port must be a member of the same VLAN. Two VLAN uplink ports can be designated,

one port in one VLAN. “Clear” option is to disable uplink forwarding.
