2.4 Connecting to Gigabit Ethernet
y The IP DSLAM has 2 X 10/100/1000 Mbps Giga Ethernet ports.
y Support full or half-duplex operation and transmission mode is using
auto-negotiation.
y All network devices connected to the switch must support auto-
negotiation. Devices without auto-negotiation will operate at half-
duplex.
y Upgrade devices to support auto-negotiation and auto-crossover
(MDI/MDIX) for full-duplex operation.
y Port 9-10 can connect to any device that uses a standard network
interface such as a Cable modem, ADSL modem, Ethernet Switch,
workstation and network interconnection device such as a bridge or
router.
y Prepare straight through shielded or unshielded twisted-pair cables
with RJ-45 plugs on both ends. Use 100Ω Category 5 cable for
connections.
y Connect one end of the cable to port 9 or 10 of the IP DSLAM, and
the other end to a standard RJ-45 station port on cable modem, ADSL
router, wireless bridge, etc.
y When inserting an RJ-45 plug, be sure the tab on the plug clicks into
position to ensure that it is properly seated.
y Do not plug a RJ-11 phone jack connector into the Ethernet port (RJ-
45 port). This may damage the VDSL. Instead, use only twisted-pair
cables with RJ-45 connectors that are compliant with the FCC
standards.

Users need to prepare 18 ~ 26 gauge one twist pair phone Line wiring
with RJ-11 plugs at both ends.
y The Modem’s RJ-11 ports are easy-to-use and do not require
installation of additional wiring. Every RJ-11 modular phone jack in the
home can become a port on the LAN.
y Networking devices can be installed on a single telephone wire that
can span up to maximum of 1.7km between the two points.
y SP3508A has embedded Splitter between every VDSL side (VDSL
Line) and POTS side (POTS port). It permits user to deliver
broadband service on the same lines as Plain Old Telephone Service
(POTS), PBX, ISDN traffic and VDSL Signal.
y When inserting a RJ-11 plug, be sure the tab on the plug clicks into
position to ensure that it is properly seated.

5.7 Link Aggregation
The Link Aggregation Control Protocol (LACP) provides a standardized
means for exchanging information between Partner Systems on a link to
allow their Link Aggregation Control instances to reach agreement on the
identity of the Link Aggregation Group. It moves the link to that Link
Aggregation Group, and enables its transmission and reception functions in
an orderly manner. In conclusion, Link aggregation lets user group up to eight
consecutive ports into a single dedicated connection. This feature can expand
bandwidth to a device on the network. LACP operation requires full-duplex
mode. For more detail information refer to IEEE 802.3ad.
5.7.1 Aggregator Setting
Parameter
Description
System Priority
A value used to identify the active LACP. The VDSL Switch with the
lowest value has the highest priority and is selected as the active
LACP.

Users can create a link aggregation across two or more ports.
Choose the "group id" and click <Get>> to use the function.
20
Download from Www.Somanuals.com. All Manuals Search And Download.
LACP
If enable, the group is LACP static trunking group. If disable, the
group is local static trunking group. All ports support LACP dynamic
trunking group. If connecting to the device that also supports LACP,
the LACP dynamic trunking group will be created automatically. If
LACP enable, users can configure LACP Active/Passive status in
each ports
Work Ports
The max number of ports can be aggregated at the same time. If it
belongs to LACP static trunking group, the exceed ports is put to
standby and able to aggregate if work ports fail. If is belongs to local
static trunking group, the number must be the same as group ports.
Click <Apply> to activate the setting.
5.7.2 Aggregator Information
When users are setting LACP aggregator, related information will be
displayed in this interface. This page is Actor and Partner trunking one group
with port 1 to port 1.
5.7.3 State Activity
A link having either two active LACP ports or one active port can perform
dynamic LACP trunking. A link has two passive LACP ports will not perform
dynamic LACP trunking because both ports are waiting for LACP protocol
packet from the opposite device. If users are active LACP’s actor, when
selecting trunking port, the active status will be created automatically.

Parameter
Active
Description
The port automatically sends LACP protocol packets.
The port does not automatically sends LACP protocol packets, and
responds only if it receives LACP protocol packets from the opposite
device.
Passive
5.8 Filter Database
The Internet Group Management Protocol (IGMP) is an internal protocol of
the Internet Protocol (IP) suite. IP manages multicast traffic by using VDSL
Switch, routers, and hosts that support IGMP. Enabling IGMP allows the ports
to detect IGMP queries and report packets and manage IP multicast traffic
through the switch. The SP3508A supports IP multicast, users can enable
IGMP protocol on the following interface. The IGMP snooping information will
also be displayed on interface. User can view different multicast group, VID
and member port in the following interface. IP multicast addresses range from
224.0.0.0 through 239.255.255.255.
5.8.1 IGMP Snooping
IGMP have three fundamental types of message as follows:
1. Query: A message sent from the queries (IGMP router or SP3508A)
asking for a response from each host belonging to the multicast group.
22
Download from Www.Somanuals.com. All Manuals Search And Download.
2. Report: A message sent by a host to the queries to indicate that the
host wants to be or is a member of a given group indicated in the
report message.
3. Leave Group: A message sent by a host to the queries to indicate that
the host has quit the membership of a specific multicast group.
5.8.2 Static MAC Address
When users add a static MAC address, it remains in the SP3508A’s address
table, regardless of whether the device is physically connected to the switch.
This saves the SP3508A from having to re-learn a device's MAC address
when disconnected or powered-off. Following is the procedure for adding a
static MAC address.
1. From the main menu, click administrator, then click Filter Database.
2. Click Static MAC Addresses.
3. In the MAC address box, enter the MAC address to and from which
the port should permanently forward traffic, regardless of the
device's network activity.
4. In the Port Number box, select a port number.
5. If tag-based (IEEE 802.1Q) VLANs are set up on the SP3508A,
static addresses are associated with individual VLANs. Type the
VID (tag-based VLANs) to associate with the MAC address.
6. Click <Add>.
23

5.8.3 Port Security
A port in security mode will be “locked” without permission of address
learning. Only the incoming packets with SMAC already existing in the
address table can be forwarded normally. User can disable the port from
learning any new MAC addresses, then use the static MAC addresses screen
to define a list of MAC addresses that can use the secure port. Enter the
settings, and then click <Submit> to apply the changes on this page.
5.8.4 MAC Filtering
MAC address filtering allows the SP3508A to drop unwanted traffic. Traffic is
filtered based on the destination addresses. For example, if the network is
congested because of high utilization from one MAC address, users can filter
all traffic transmitted from that MAC address.

5.9 VLAN Configuration
A Virtual LAN (VLAN) is a logical network grouping that limits the broadcast
domain. It allows user to isolate network traffic so only members of the VLAN
receive traffic from the same VLAN members. Basically, creating a VLAN
from a SP3508A is logically equivalent of reconnecting a group of network
devices to another Layer 2 switch. However, all the network devices are still
plug into the same SP3508A physically. The VDSL Switch supports port-
based and protocol-base VLAN in web management page. In the default
configuration, VLAN support is enabling and all ports on the SP3508A belong
to default VLAN (VID: 1).
Support Multiple VLAN (IEEE 802.1Q VLAN)
Port-based Tagging rule VLAN is an IEEE 802.1Q specification standard.
Therefore, it is possible to create a VLAN across devices from different
SP3508A venders. IEEE 802.1Q VLAN uses a technique to insert a “tag” into
the Ethernet frames. Tag contains a VLAN Identifier (VID) that indicates the
VLAN numbers.

Support Protocol-based VLAN
In order for an end station to send packets to different VLAN, it has to be
either capable of tagging packets with VLAN tags or attached to a VLAN-
aware bridge that is capable of classifying and tagging the packet with
different VLAN ID based on not only default PVID but also other information
about the packet, such as the protocol. VDSL Switch will support protocol-
based VLAN classification by means of both built-in knowledge of layer 2
packet formats used by selected popular protocols, such as Novell IPX and
AppleTalk’s EtherTalk, and some degree of programmable protocol matching
capability.
5.9.1 Basic
This interface allows users to assign VLAN membership to each port. The
procedure for setting VLAN member is as follow.
1. From the main menu, under ‘Administrator’, click on <VLAN
config>.
2. Click <Add>.
3. Type a VID (Valid Range: 2-4094). The default is 1.
4. From the Available ports box, select ports to add to the VLAN and
click <Add>.
5. Click <Apply>.
26
Download from Www.Somanuals.com. All Manuals Search And Download.
5.9.2 Port VID
The interface sets the Port VLAN ID that will be assigned to untagged traffic
on a given port. For example, if port 10's Default PVID is 100, all untagged
packets on port 10 will belong to VLAN 100. The default setting for all ports is
VID 1. This feature is useful for accommodating devices that you want to
participate in the VLAN but that don't support tagging. Only one untagged
VLAN is allowed per port.
Parameter
Description
Ingress Filtering
Ingress filtering lets frames belonging to a specific VLAN to be
forwarded if the port belongs to that VLAN.
Forward only packets with VID matching this port's configured VID.

5.10 Spanning Tree
The Spanning-Tree Protocol (STP) is a standardized method (IEEE 802.1D)
for avoiding loops in SP3508A networks. When STP enabled, ensure that
only one path at a time is active between any two nodes on the network. It is
recommended that users enable STP on all SP3508A to ensure a single
active path on the network.

Chapter 6 Application
The VDSL provides home network architecture. Transforming an apartment
into a Multiple-Family Home network area and sharing a single internet
account for multiple users via Router & Cable Modem. It can provide
unlimited access time in the internet at a reasonable low price.
Bridging Functions
The SP3508A provides full transparent bridging function. It automatically
connects node addresses that are later used to filter and forward all traffic
based on the destination address. When traffic passes between devices
attached to the shared collision domain, those packets are filtered from the
VDSL Switch. However, when traffic must be passed between unique
segments (i.e., different ports of the VDSL Switch), a temporary link is set up
between the switch’s port in order to pass this traffic, via the high-speed
VDSL fabric.
Transceiver Function
The SP3508A supports Ethernet to VDSL convert. It can transmit or receive
packet between Ethernet RJ-45 port and VDSL RJ11 port.
Flexible Configuration
The SP3508A is not only designed to segment the network, but also to
provide a wide range of options in the configuration of home network
connections. It can be used as a simple stand-alone VDSL Switch or can be
connected with another VDSL Switch, Cable modem, Router, XDSL, ISDN,
gateway or other network interconnection devices in various configurations.

7.3 Appendix C: System Diagnostics
7.3.1 Power and Cooling Problems
If the POWER indicator does not turn on when the power cord is plugged in,
users may have a problem with the power outlet, power cord, or internal
power supply as explained in the previous section. However, if the unit should
turn itself off after running for a while, check for loose power connections,
power loss or surges at the power outlet, and verify that the fan on back of
the unit is unobstructed and running prior to shutdown. If you still cannot
isolate the problem, then the internal power supply may be defective. In this
case, contact thesupplier for assistance.
7.3.2 Installation
Verify that all system components have been properly installed. If one or
more components appear to be malfunctioning (e.g., the power cord or
network cabling), then test them in an alternate environment where you are
sure that all the other components are functioning properly.
7.3.3 Transmission Mode
The selections of the transmission mode for the RJ-45 ports are auto-
negotiation using the default method. Therefore, if the Link signal is disrupted
(e.g., by unplugging the network cable and plugging it back in again, or by
resetting the power), the port will try to reestablish communications with the
attached device via auto-negotiation. If auto-negotiation fails, then
communications are set to half duplex by default. Based on this type of
industry-standard connection policy, if users are using a full-duplex device
that does not support auto-negotiation, communications can be easily lost
(i.e., reset to the wrong mode) whenever the attached device is reset or
experiences a power fluctuation. The best way to resolve this problem is to
upgrade these devices to version that will support auto-negotiation.

7.3.4 Cabling
1. Verify that the cable type is correct. Be sure RJ-45 cable connectors are
securely seated in the required ports. Use 100Ω straight-through cables
for all standard connections.
2. Use Category 5 cable for 100/1000Mbps Fast Ethernet connections, or
Category 3, 4 or 5 cables for standard 10Mbps Ethernet connections.
3. Be sure RJ-11 phone wiring uses 18~26 gauge.
4. Make sure all devices are connected to the network.
5. When cascading two devices using RJ-45 station ports at both ends of
the cable (i.e., not an MDI port), make sure a crossover cable is used.
Crossover cable should only be used if a MDI port is not available.
7.3.5 Physical Configuration
If problems occur after altering the network configuration, restore the original
connections, and try to track the problem down by implementing the new
changes, one step at a time. Ensure that cable distances and other physical
aspects of the installation do not exceed recommendations.
7.3.6 System Integrity
As a last resort verify the SP3508A integrity with a power-on reset. Turn the
power to the SP3508A off and then on several times. If the problem still
persists and you have completed all the preceding diagnoses, contact your
dealer for assistance.
