2.5 Making UTP Connections

The 10/100/1000 twisted-pair copper (TP) port supports the following connection types a nd 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 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 port is featured with auto-negotiation function and full capability to support connection to any
Ethernet devices. The port performs a negoti ation proce ss for the speed and duplex configuration with
the connected device automatically when each ti me a link is being esta blished. 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 port 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 set port
configuration to one of non-auto (forced) operating modes and specify speed and duplex mode which
match the configuration used by the connected device.

T wo methods for setting copper port configuration are as follows:

3.2 Converter Function

The device supports the following data conversions between fiber cable and twisted-pair Cat.5 (cop­per) cable:

The data rate on twisted-pair segment depends on the link speed finally esta blished with the link part­ner.

-20-

3.3 Link Fault Pass Through Function

Description

When the Link Fault Pass Through (LFPT) function is enabled and the media converter detects a link
fault on one port segment, it will force the other port segment link down. It looks like that a link fault is
passed from one port to the other.

The following example illustrates a link fault occurs on the fiber cable (any one ca ble in a duplex fiber
connection). The link fault is forwarded to both Giga bit link partners finally by LFPT operation of two
media converters.

Both Gigabit devices will also detect a link fault on ea ch Cat.5 connection, although the real fault occurs
on the fiber connection exactly.

The following example illustrate s a real link fault occurs on one Cat.5 a nd the link fault is pa ssed to the
other Cat.5 over two converters and the fiber cable by LFPT operation. Finally, the other link partner
also detects a link fault.

Advantage

The function allows two remote link partners of the media converters detect the link fault finally no
matter where the exact fault occurs. It allows the upper application takes necessary action in case a
real link fault occurs in a ny cable segment.

Methods to enable the function

The LFPT function can be enabled by:

Hardware setting: DIP SW6 is set to ON position
Software setting: W eb management ->

Configuration -> System -> [Link fault pass through]

Enable Enable Settings not recommended (possible double-tagging)

[Ingress Keep Tag] options:
Enable - The VLAN tag in the received VLAN-tagged packet will be kept as it is and is

not stripped in whole conversion operation.

Disable - The VLAN tag data in the received VLAN-tagged packet is stripped (removed).

[Egress Insert Tag] options:
Enable - Insert a tag into the packet in egress. The tag inserted is based on the rule below:

Incoming Packet Type Tag inserted
Untagged Ingress port Default Tag
Priority-tagged Ingress port Default Tag
VLAN-tagged Received packet own tag

Disable - No tagging is performed.

-23-

[Default Tag -VID], [Default Tag - CFI], [Default Tag - Priority] settings

These settings compose one ingress port Default Tag. This tag is used when a tag insertion is required
for untagged packets.

802.1Q Filtering

802.1Q VID Filtering function allows to admit or reject certain VID tagged packets. Up to 16 allowed
(positive list) or rejected (negative list) VIDs can be configured. This function allows to limit certain
packets to pass from one link segment to another one.

[VID Table] options

Disable - 802.1Q VID filtering is disa bled.
Allowed VID - Only the VLAN-tagged packets with VIDs in VID table are admitted.
Rejected VID - The VLAN-tagged packets with VIDs in VID table are rejected and dropped.

For untagged a nd priority-tagged packets, the ingre ss [Default T ag - VID], also called PVID is used for
VID filtering. If it is in Allowed VID ta ble, the untagged packet is allowed to pa ss; otherwise, dropped.
If it is in Rejected VID table, the untagged packet is dropped.

3.6 QoS Function

The device provides a powerful Quality of Service (QoS) function to guide the packet forwarding in
four priority cla sses. The versatile cla ssification methods can meet most of the application needs.

The function is useful for guiding the incoming traffic on high data rate port into low data rate port in
priority . The f ollowing figure illustrates the QoS operation flow when a pa cket received on the ingre ss
port until it is tra nsmitted out from the egress port:

Since the media converter can support full wire speed conversion for 1000Mbps to 1000Mbps, QoS
function is not essential for such a pplication. It is suggested to disa ble the QoS function f or 1000Mbps
to 1000Mbps conversion.

-25-

3.6.1 Packet Priority Classification

Each received packet is examined and classified into one of four priority classes, Class 3, Class 2,
Class 1 a nd Cla ss 0 upon rece ption. The device provides the f ollowing 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 port has its own mapping table for 802.1p classification.
DSCP mapping table : Two 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.

3.6.2 Priority Class Queues

Each port in the device is equipped with four priority class egress queues to store the packets for
tra nsmission. A pa cket is stored into the cla ss queue which is associated to the classified priority cla ss.
For example, a pa cket is stored into Class 3 egress queue if it is classified a s priority Class 3.

3.6.3 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.

-26-

3.7 SNMP Trap Function

SNMP tra p function allows the device to send tra p message to a n SNMP trap host over SNMP protocol
when the associated trap event occurs.

SNMP Trap settings

The settings are used to configure a trap host who can receive the SNMP trap message issued from a
media converter device unit.

[SNNP Tra p] Enable / disa ble SNMP tra p function
[Community Name] The community string bound in a trap message
[Trap IP Address] The IP address of the target SNMP trap host who is allowed to receive the

traps.

SNMP Trap events

The following events are defined for generating a trap message when the event occurs on the unit.

z The device boot up.
z TP copper port link down
z TP copper port link up (link recovery).
z FX fiber port link down
z FX fiber port link up (link recovery).

The following exa mple illustrates an event of FX port link down occurs a nd is detected by the device.
Then, it generates a trap message to the SNMP trap host PC.

4.4.1 Management VLAN

Management VLAN settings allow administrator to access the device and perform the web manage­ment over a dedicated VLAN only.

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

1. If the 802.1Q Control function is disabled, Management VLAN settings are ignored and no

VLAN li mitation is applied in accessing the web management interface. The 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

web management interface. The 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 http server only accepts tagged manage-

ment 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.

Summary of the rules:

802.1Q Control Management VLAN VID Embedded Http (Web) Server operation
Disabled Ignore Accept untagged web packets

Reply untagged packets

Enabled VID=0 Accept untagged web packets

Reply untagged packets

Enabled VID<>0 Accept matched tagged web packets only

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

Notes:

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

required.

2 . Default [Management VLAN - VID] is equal to zero. It is allowed to access the device from

any untagged PC web browser.

3. Most of the PCs are tag-incapable for LAN access. Be sure the rules are followed before

setting [Management VLAN - VID] not equal to zero.

[DSCP M apping] Click to configure DSCP mapping ta ble.
[Apply] Click to apply the configuration cha nge
[Refresh] Click to refresh current configuration

Notes:

1. 802.1p classification is superior over DSCP classification if both are en abled. 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.

2. 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.

3. 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.

4. It is suggested to apply QoS Control function only on 1000M to 100M conversion. Under

1000M to 1000M full wire speed conversion, the effect of QoS control function is not
obvious.
