VDSL2 Brief
VDSL2 (Very-High-Bit-Rate Digital Subscriber Line 2, ITU-T G.993.2 Standard) is an access technology that exploits the existing
infrastructure of copper wires that were originally deployed for POTS services. It can be deployed from central offices, from fibre-fed
cabinets located near the customer premises, or within buildings.
ITU-T G.993.2 VDSL2 is the newest and most advanced standard of DSL broadband wireline communications. Designed to support
the wide deployment of Triple Play services such as voice, video, data, high definition television (HDTV) and interactive gaming,
VDSL2 enables operators and carriers to gradually, flexibly, and cost efficiently upgrade existing xDSL-infrastructure.
ITU-T G.993.2 (VDSL2) is an enhancement to G.993.1 VDSL that permits the transmission of asymmetric and symmetric
(Full-Duplex) aggregate data rates up to 200 Mbit/s on twisted pairs using a bandwidth up to 30 MHz.
VDSL2 deteriorates quickly from a theoretical maximum of 200 Mbit/s at 'source' to symmetric 100 Mbit/s at 0.3 km and 50 Mbit/s at
1 km, but degrades at a much slower rate from there, and still outperforms VDSL. Starting from 1,6 km its performance is equal to
ADSL2+.
ADSL-like long reach (LR) performance: ADSL-like long reach performance is one of the key advantages of VDSL2. LR-VDSL2
enabled systems are capable of supporting speeds of around 1-4 Mbit/s (downstream) over distances of 2.5 km, gradually
increasing the bit rate up to symmetric 100Mbit/s as loop-length shortens. This means that VDSL2-based systems, unlike VDSL1
3
Page 5
NV-1602S 16 Ports VDSL2 Managed IP DSLAM with Redundant Power USER’S MANUAL Ver.A2
systems, are not limited to short loops or MTU/MDUs only, but can also be used for medium range applications.
VDSL2 IP DSLAM
The NV-1602S utilize Lantiq(Infineon) Vinax VDSL2 Chipset, which is a VDSL2 IP DSLAM that aggregates 16 ports into Giga
Ethernet uplinks for high-speed data/Internet services.
Based on DMT VDSL2 technologies, NV-1602S extends data service with line rate of solution for services such as remote lecturing,
telemedicine, video conferencing, Video-on-Demand (VoD), IP-TV, Internet access and other various high-speed data applications.
When the number of subscribers increases, the second uplink Giga Ethernet interface can be used to daisy chain to another
NV-1602S. Alternatively, multiple NV-1602S can be connected to another LAN switch to from a two-tier configuration, thus
supporting a lot more subscribers. The NV-1602S is an ideal solution for delivering cost-effective, high-performance
broadband/multimedia services to Multi-Tenant Units (MTUs) or Multi-Dwelling Units (MDUs) such as hotels, campus, hospitals and
telecom.
The NV-1602S provides the important features necessary for robust networks
Key features and benefits :
Jumbo packet up to 9k byte: In computer networking, jumbo frames are Ethernet frames with more than 1500 bytes of
payload. Conventionally, jumbo frames can carry up to 9000 bytes of payload, but variations exist and some care must be
taken when using the term.
The original 1500-byte payload size for Ethernet frames was used because of the high error rates and low speed of
communications. Thus, if one receives a corrupted packet, only 1500 bytes (plus 18 bytes for the frame header and other
overhead) must be re-sent to correct the error. However, each frame requires that the network hardware and software
4
Page 6
NV-1602S 16 Ports VDSL2 Managed IP DSLAM with Redundant Power USER’S MANUAL Ver.A2
process it. If the frame size is increased, the same amount of data can be transferred with less effort. This reduces CPU
utilization (mostly due to interrupt reduction) and increases throughput by allowing the system to concentrate on the data in
the frames.
IEEE 802.1q Q-in-Q VLAN for performance & security: The VLAN feature in the switch offers the benefits of both security
and performance. VLAN is used to isolate traffic between different users and thus provides better security. Limiting the
broadcast traffic to within the same VLAN broadcast domain also enhances performance. VLAN support enabling advanced
techniques such as 802.1Q-in-1Q to be deployed.
And support GVRP up to 4k V-Lan groups.
IEEE 802.1x: port base network access control, this function for wireless users connecting Authentication.
Spanning tree: Support IEEE 802.1d STP/IEEE 802.1w RSTP/IEEE-802.1s MSTP. For mission critical environments with
multiple switches supporting STP, you can configure the switches with a redundant backup bridge path, so transmission and
reception of packets can be guaranteed in event of any fail-over switch on the network.
IEEEE 802.1p QoS(COS) with Four Priority Queues:
The QoS(Quality Of Service) feature provides four internal queues to support four different classifications of
traffic. High priority packet streams experience less delay inside the switch, which supports lower latency for
certain delay-sensitive traffic. The NV-1602S can classify the packet as one of the 8-level priority to 4 –level
queue mapping. I.e. Highest, SecHigh, Lowest, SecLow.
Differentiated Services or DiffServ: is a computer networking architecture that specifies a simple, scalable and
coarse-grained mechanism for classifying, managing network traffic and providing Quality of Service (QoS) on
5
Page 7
NV-1602S 16 Ports VDSL2 Managed IP DSLAM with Redundant Power USER’S MANUAL Ver.A2
modern IP networks. DiffServ can, for example, be used to provide low-latency to critical network traffic such as
voice or streaming media while providing simple best-effort service to non-critical services such as web traffic or
file transfers.
DiffServ uses the 6-bit Differentiated Services Code Point (DSCP) field in the IP header for packet
classification purposes. DSCP replaces the outdated Type of Service field.
IGMP Snooping : Snooping by 256 IP multicast table for VOD (Video on demand) and Video conference and Internet games
application.
HTTPS (SSL) Web Access: Hypertext Transfer Protocol Secure (HTTPS) is a combination of the Hypertext Transfer
Protocol with the SSL protocol to provide encrypted communication and secure identification of a network web
server. HTTPS connections are often used for payment transactions on the World Wide Web and for sensitive
transactions in corporate information systems.
SNMP MIB Support: SNMP v1/v2c/v3 management and trap function
Support MIB tables: MIB-II (RFC 1213), Bridge MIBs (RFC 1493), Ethernet-like MIB (RFC 1643 & RFC 2665), private-MIB,
USM-MIB (RFC 2574), VACM-MIB (RFC 2575) and RMON-MIB 1, 2, 3, 9 groups (RFC 1757& RFC 2819).
Broadcast/Multicast/Unknown-unicast Storm Control: To limit too many broadcast/multicast/unknown-unicast flooding
in the network, broadcast/multicast storm control is used to restrict excess traffic. Threshold values are available to control
the rate limit for each port. Packets are discarded if the count exceeds the configured upper threshold.
Port Mirroring: This function could be mirroring and duplicated client side action, but Need to be with mirroring AP as
6
Page 8

Session wall or other.
ACL(Access Control List): On some types of proprietary computer hardware, an Access Control List refers to rules that
are applied to port numbers or network daemon names that are available on a host or other layer 3, each with a list of hosts
and/or networks permitted to use the service. Both individual servers as well as routers can have network ACLs. Access
control lists can generally be configured to control both inbound and outbound traffic, and in this context they are similar to
firewalls. Like Firewalls, ACLs are subject to security regulations and standards.
Link Layer Discovery Protocol (LLDP): is a vendor-neutral Link Layer protocol in the Internet Protocol Suite used by
network devices for advertising their identity, capabilities, and neighbors on a IEEE 802 local area network, principally wired
Ethernet. The protocol is formally referred to by the IEEE as Station and Media Access Control Connectivity Discovery
specified in standards document IEEE 802.1AB.
Speed Rate Control(Traffic shaping): Supports speed rate control function from 128k to 100Mbps.
Note:
Regarding our NV-1602S' principle of bandwidth control, which must rely on flow control to limit bandwidth over
hardware, as long as client side doesn't support flow control, the upstream bandwidth control is invalid, so for this
case, client side must support flow control function.
In band Management: Provides a console(RS232) port for setup IP or other function
Out Of Band Management: Supports remote control by Web-based Management easy-to-use configuration and ongoing
monitoring. This software is embedded in the switch and delivers remote, intuitive management of the switch and connected
NIC devices through a single IP address. The NV-1602S are easy-to-configured and deployed, and offering a compelling
7

option in terms of cost, performance, scalability and services compared to traditional repeater HUB solutions.
2 Dual Media for Flexible Fiber Connection:Dual media port 9 and 10 are provided for flexible fiber/copper auto link
connection. You can select to install optional transceiver modules in these slots for short, medium or long distance fiber
backbone attachment. Use of the SFP will auto disable their corresponding built-in 10/100/1000Base-T connections.
DHCP Client: Dynamic Host Configuration Protocol (DHCP) for auto configuration management IP.
TFTP Protocol: Trivial File Transfer Protocol(TFTP) for new version firmware remote upgraded
Firmware upgrade support : HTTP / TFTP protocol.
Scalability: Up to 100 Mbps symmetric performance over single-pair wiring for VDSL2 Channel.
Interleave delay time: To prevent the transmission against burst errors. Please note that enable interleave delay
function will reduce a few vdsl2 bandwidth.
Noise Margin(SNRM): In electrical engineering, noise margin is the amount by which a signal exceeds the minimum
amount for proper operation. NV-1602S default value is 6db for telecom standard.
Upstream Power Back-Off (UPBO): helps to run services over loops with different length co-located in the same cable
binder (“mixed length” deployments), especially in FEXT-dominated noise environment.
Strong FEXT generated by short loops can significantly degrade the performance of long loops if UPBO is not applied.
8
Page 10
NV-1602S 16 Ports VDSL2 Managed IP DSLAM with Redundant Power USER’S MANUAL Ver.A2
On the other hand, UPBO reduces the transmit power of short loops and thus degrades their performance as well.
The UPBO technique should take in account both issues.
Downstream Power Back-Off (DPBO): The development of Triple Play services requires higher bandwidth. Higher
bandwidth and substantial performance gain can be reached by deploying DSLAM-s in a remote side cabinet near to the
customer premises. There is no problem at clean networks where all the customers are connected to the same local
cabinet.
Trellis coding : The name trellis was coined because a state diagram of the technique, when drawn on paper closely
resembles the trellis lattice used in rose gardens. The scheme is basically a convolutional code of rates (r,r+1).
Ungerboeck's unique contribution is to apply the parity check on a per symbol basis instead of the older technique of
applying it to the bit stream then modulating the bits. The key idea he termed Mapping by Set Partitions. This idea was to
group the symbols in a tree like fashion then separate them into two limbs of equal size. At each limb of the tree, the
symbols were further apart. Although in multi-dimensions, it is hard to visualize, a simple one dimension example illustrates
the basic procedure. Suppose the symbols are located at [1, 2, 3, 4, ...]. Then take all odd symbols and place them in one
group, and the even symbols in the second group. This is not quite accurate because Ungerboeck was looking at the two
dimensional problem, but the principle is the same, take every other one for each group and repeat the procedure for each
tree limb. He next described a method of assigning the encoded bit stream onto the symbols in a very systematic procedure.
Once this procedure was fully described, his next step was to program the algorithms into a computer and let the computer
search for the best codes. The results were astonishing. Even the most simple code (4 state) produced error rates nearly
1,000 times lower than an equivalent uncoded system. For two years Ungerboeck kept these results private and only
conveyed them to close colleagues. Finally, in 1982, Ungerboeck published a paper describing the principles of trellis
modulation.

NV-1602S 16 Ports VDSL2 Managed IP DSLAM with Redundant Power USER’S MANUAL Ver.A2
A flurry of research activity ensued, and by 1990 the International Telecommunication Union had published modem
standards for the first trellis-modulated modem at 14.4 kbit/s (2,400 baud and 6 bits per symbol). Over the next several years
further advances in encoding, plus a corresponding symbol rate increase from 2,400 to 3,429 baud, allowed modems to
achieve rates up to 34.3 kbit/s (limited by maximum power regulations to 33.8 kbit/s). Today, the most common
trellis-modulated V.34 modems use a 4-dimensional set partition which is achieved by treating two 2-dimensional symbols as a
single lattice. This set uses 8, 16, or 32 state convolutional codes to squeeze the equivalent of 6 to 10 bits into each symbol
sent by the modem (for example, 2,400 baud × 8 bits/symbol = 19,200 bit/s).
Once manufacturers introduced modems with trellis modulation, transmission rates increased to the point where interactive
transfer of multimedia over the telephone became feasible (a 200 kilobyte image and a 5 megabyte song could be downloaded
in less than 1 minute and 30 minutes, respectively). Sharing a floppy disk via a BBS could be done in just a few minutes,
instead of an hour. Thus Ungerboeck's
Echo cancellation : The term echo cancellation is used in telephony to describe the process of removing echo from a voice
communication in order to improve voice quality on a telephone call. In addition to improving subjective quality, this process
increases the capacity achieved through silence suppression by preventing echo from traveling across a network.
Two sources of echo have primary relevance in telephony: acoustic echo and hybrid echo.
Echo cancellation involves first recognizing the originally transmitted signal that re-appears, with some delay, in the transmitted
or received signal. Once the echo is recognized, it can be removed by 'subtracting' it from the transmitted or received signal.
This technique is generally implemented using a digital signal processor (DSP), but can also be implemented in software. Echo
cancellation is done using either echo suppressors or echo cancellers, or in some cases both.
INP(Impulse Noise Protection): Impulse noise in multicarrier communication systems behaves effectively as a modulating
10
Page 12
NV-1602S 16 Ports VDSL2 Managed IP DSLAM with Redundant Power USER’S MANUAL Ver.A2
signal that controls the first moment of the background Gaussian noise. The composite noise, which is the aggregate of the
Gaussian noise and impulse noise, has a probability density function that is conditionally Gaussian with non-zero average,
hence referred to as biased-Gaussian. The BER-equivalent power of the composite noise source is defined as the power of a
pure Gaussian noise source that yields the same bit-error rate (BER). The BER-equivalent noise for a biased-Gaussian noise
is simply the amplified version of the underlying Gaussian noise source. The amplification factor is derived from the
characteristics of the impulse interference. Any bit-loading algorithm designed for Gaussian noise sources is also applicable to
biased-Gaussian noise sources provided that the BER-equivalent SNR is used in place of the measured SNR.
Syslog : is a standard for logging program messages. It allows separation of the software that generates messages from the
system that stores them and the software that reports and analyzes them. It also provides devices which would otherwise be
unable to communicate a means to notify administrators of problems or performance.
Syslog can be used for computer system management and security auditing as well as generalized informational, analysis,
and debugging messages. It is supported by a wide variety of devices (like printers and routers) and receivers across multiple
platforms. Because of this, syslog can be used to integrate log data from many different types of systems into a central
repository.

2.3 SFP Fiber Optics
A gigabit interface converter (SFP) is a transceiver that converts electric currents (digital highs and lows) to optical signals, and
optical signals to digital electric currents. The SFP is typically employed in fiber optic and Ethernet systems as an interface for
high-speed networking. The data transfer rate is 1.25 gigabit per second.
SFP modules allow technicians to easily configure and upgrade electro-optical communications networks. The typical SFP
transceiver is a plug-in module that supports hot-plugging (it can be removed and replaced without turning off the system).
The devices are economical, because they eliminate the necessity for replacing entire boards at the system level. Upgrading
can be done with any number of units at a time, from an individual module to all the modules in a system. SFP (Small Form
Pluggable Transceivers), meet the Gigabit Interface Converter specification Rev. 5.4 (MOD_DEF4) industry standard.

Page 30
NV-1602S 16 Ports VDSL2 Managed IP DSLAM with Redundant Power USER’S MANUAL Ver.A2
2.7 DC Power Socket
The NV-1602S can be powered two -48V DC power supply. The DC power interface is a 5-pin terminal block is located below the AC
socket of the DSLAM. 2P is for accommodating one DC power input and other 2P is for accommodating another DC power input.
The center pin of the terminal block is FGND. The DC power should be connected to a well-fused power supply. When using a DC
voltmeter, Please check for proper voltage: -75V ~ -36 VCD, and make sure that the polarity is correct.
**Redundancy
During operation, both power supplies are switched on and share the current load. In case that one of them should fail, the other
will instantaneously take 100% of the load without any loss. Similarly, if one power supply is removed from servicing, it can be
switched off and removed while the chassis continues functioning.
Note:
It is recommend that the -48VDC be supplied directly and independently by a power feeding system and also avoid having a parallel
or mutual connection with other -48VDC power supplier of telecom equipment. This is to guarantee our products against interference
by other equipment while they are working.

3.3 General Rules
Before making any connections to the IP DSLAM, note the following rules:
• Ethernet Port (RJ-45)
All network connections to the bridge Ethernet port must be made using Category 5 UTP/STP or above for
100Mbps, Category 3, 4 UTP for 10Mbps.
No more than 100 meters of cabling may be use between the MUX or HUB and an end node.
• VDSL2 Port (RJ-11)
All network connections to the RJ-11port must use 24~26 gauge with twisted pair phone wiring.
We do not recommend the use of the telephone line 28 gauge or above.
The RJ-11 connectors have six positions, two of which are wired. The router uses the center two pins. The
pin out assignment for these connectors is presented below.
Please note that the line port is no polarity, therefore user can reverse the two wires of the phone cable
when installed.

3.4 Connection Configuration
The IP DSLAM has 16 x 100 Mbps VDSL2 ports. And 2 Giga Ethernet ports which support connection to 10/100/1000 Ethernet.
Support full or half-duplex operation and Auto MDI/MDIX. The transmission mode is using auto-negotiation. Therefore, the
devices attached to these ports must support auto-negotiation unless they will always operate at half duplex. If transmissions
must run at full duplex, but the attached device does not support auto-negotiation, then you should upgrade this device to a
newer version that supports auto-negotiation.
Use any of the 17~18 ports to connect to devices such as a workstation, server, bridge or router. You can also cascade to
another compatible IP DSLAM or hub by connecting an MDI or MDIX port.
1. User can connect an (17~18) station port on the IP DSLAM to any device that uses a standard network interface such as a
optical fiber converter, workstation or server, or also to a network interconnection device such as a bridge or router
(depending on the port type implemented).
2. Prepare the network devices you wish to network. Make sure you have installed VDSL2 CPE Bridge making a connection to
any of the IP DSLAM (L1~L16) station ports. You also need to prepare 24~26 gauge with twisted pair phone wire with RJ11
plugs at both ends.
3.Connect one end of the cable to the RJ-45 port of the network interface card, and the other end to any available (9~10) station
port on the IP DSLAM. Every port support either 10 /100/1000 Mbps connections. When inserting an RJ-45 plug, be sure the
tab on the plug clicks into position to ensure that it is properly seated.
Notes:
1. Be sure each twisted-pair cable (RJ-45) do not exceed by 100 meters (328 feet).
2. We advise using Category 5 cable for Cable Modem or router connections or to attach to any high bandwidth device to avoid
any confusion or inconvenience.

NV-1602S 16 Ports VDSL2 Managed IP DSLAM with Redundant Power USER’S MANUAL Ver.A2
4. Setting IP Address by Console Port
When you are going to login a IP DSLAM through the web page, you have to configure the IP address first. The default IP address /
netmask / default gateway of a switch is 192.168.16.249 / 255.255.255.0 / 192.168.16.1, without making any configuration
changes in advance, you can login a IP DSLAM with default IP address as long as the default IP address can function properly in
your network environment. Otherwise, you have to re-configure the IP address, subnet mask and default gateway. The following
show how to configure the IP address of a IP DSLAM.
First, login with the console port.
Username: admin
Password: 123
Second, you will now enter the “IP Address ”, then, setup the IP address, subnet mask and gateway.
Switch# configure
Switch(config)# ip address 192.168.1.1 255.255.255.0
Switch(config)# ip default-gateway 192.168.1.254
Notes:
1. As you may identify from the commands above Industrial VDSL2 Router is a Linux based device.
Many of the common Linux commands can be used here. However, please consider that you purchased a VDSL2 device, not a PC.
And always keep in mind that provider gives you support for configuring a standard VDSL2 device. If you try to use the VDSL2
device as a Linux hardware platform and modify its internal software structure, there is no support or warranty on the unit.
2. The command line only support L2 switch function such as VLAN, rate control, STP...etc, it does not support VDSL2 configuration
command line such as VDSL2 channel, Interleave delay. The L2 switch function was wrote in the chapter 4, and the VDSL2 function
was wrote in the chapter 5.

4.0.3.1 VLAN
4.0.3.1.0
A Virtual LAN (VLAN) is a logical network group that limits the broadcast domain. It allows you to isolate network traffic so
only members of the VLAN receive traffic from the same VLAN members. Basically, creating a VLAN within a switch is
logically equivalent of reconnecting a group of network devices to another Layer 2 switch. However, all the network devices are
still plugged into the same switch physically. A station can belong to more than one VLAN group. VLAN prevents users from
accessing network resources of another on the same LAN, thus the users can not see the hard disks and printers of another user in
the same building. VLAN can also increase the network performance by reducing the broadcast traffic and enhance the security of
the network by isolating groups.
This Switch supports two types of VLANs:
• Port-based
• IEEE 802.1Q (tag) –based
Virtual LANs
44
Page 46
NV-1602S 16 Ports VDSL2 Managed IP DSLAM with Redundant Power USER’S MANUAL Ver.A2
Notes:
1. The user can select Port-Based VLAN or 802.1q tagging VLAN to use.
2. Example of VLAN setting on “Appendix B”.
Port-based VLANs are VLANs where the packet forwarding decision is made based on the destination MAC address and its
associated port. You must define the outgoing ports allowed for each port when you use port-based VLANs. In port-based VLANs,
the packets received from one port can only be sent to the ports which are configured to the same VLAN. As shown in the
following figure, the switch administrator configured port 1~2 as VLAN 1 and port 3~4 as VLAN 2. The packets received from
port 1 can only be forwarded to port 2. The packets received from port 2 can only be forwarded to port 1. That means the
computer A can send packets to computer B, and vice versa. The same situation also occurred in VLAN 2. The computer C and D
can communicate with each other. However, the computers in VLAN 1 can not see the computers in VLAN 2 since they belonged
to different VLANs.
45
Page 47
NV-1602S 16 Ports VDSL2 Managed IP DSLAM with Redundant Power USER’S MANUAL Ver.A2
IEEE 802.1Q (tag) -based VLANs enable the Ethernet functionality to propagate tagged packets across the bridges and provides
a uniform way for creating VLAN within a network then span across the network. For egress packet, you can choose to tag it or
not with the associated VLAN ID of this port. For ingress packet, you can forward this packet to a specific port as long as it is also
in the same VLAN group.
The 802.1Q VLAN works by using a tag added to the Ethernet packets. The tag contains a VLAN Identifier (VID) which belongs
to a specific VLAN group. And ports can belong to more than one VLAN.
46
Page 48
NV-1602S 16 Ports VDSL2 Managed IP DSLAM with Redundant Power USER’S MANUAL Ver.A2
The difference between a port-based VLAN and a tag-based VLAN is that the tag-based VLAN truly divided the network into
several logically connected LANs. Packets rambling around the switches can be forwarded more intelligently. In the figure shown
below, by identifying the tag, broadcast packets coming from computer A in VLAN1 at sw1 can be forwarded directly to VLAN1.
However, the switch could not be so smart in the port-based VLAN mechanism. Broadcast packets will also be forwarded to port
4 of sw2. It means the port-based VLAN can not operate a logical VLAN group among switches.
47

NV-1602S 16 Ports VDSL2 Managed IP DSLAM with Redundant Power USER’S MANUAL Ver.A2
The NV-1602S supports both port-based VLAN and tag-based (802.1Q) VLAN modes. The default configuration is tag-based
(802.1Q) VLAN. In the 802.1Q VLAN, initially, all ports on the switch belong to default VLAN, VID is 1.
Notes:
1. Do not delete the default VLAN group in 802.1Q VLAN mode.
2. dot1q means 802.1Q tagging VLAN.
4.0.3.1.1 VLAN Mode
VLAN Mode: Port based
Packets can go among only members of the same VLAN group. Note all unselected ports are treated as belonging to another single

NV-1602S 16 Ports VDSL2 Managed IP DSLAM with Redundant Power USER’S MANUAL Ver.A2
VLAN. If the port-based VLAN enabled, the VLAN-tagging is ignored.
show vlan mode
Display the current VLAN mode.
vlan mode (disabled|port-based|dot1q)
Change VLAN mode.
Parameters:
(disabled|port-based|dot1q) specifies the VLAN mode.
Note:
1. Change the VLAN mode for every time, user have to restart the switch for valid value.
2. dot1q means 802.1Q tagging VLAN.
VLAN Mode: 802.1Q
In the setting, port was set to Untagged if devices underneath this port do not support VLAN-tagging. Thus the switch can send
untagged frames to this port. Consequently, device that do not support VLAN-tagging or do not enable VLAN tagging could
successfully fetch the incoming frames and could communicate with device that transfers tagged frames, and vice versa. In the
following figure, two different types of devices want to communicate with each other. Since computer A support 802.1Q VLAN
and computer B do not, you have to configure two ports both beneath the same VLAN group, and set left port to “Tagged”, right
port to “Untagged”. Therefore, two devices will receive packet type as they desired.

4.0.3.1.2 Advanced 802.1Q VLAN Setting
Ingress filters configuration
When a packet was received on a port, you can govern the switch to drop it or not if it is an untagged packet. Furthermore, if the
received packet is tagged but not belonging to the same VALN group of the receiving port, you can also control the switch to
forward or drop the packet. The example below configures the switch to drop the packets not belonging to the same VLAN group
and forward the packets not containing VLAN tags.

4.0.3.1.3 QinQ VLAN Setting
Business customers of service providers often have specific requirements for VLAN IDs and the number of VLANs to be
supported. The VLAN ranges required by different customers in the same service-provider network might overlap, and traffic of
customers through the infrastructure might be mixed. Assigning a unique range of VLAN IDs to each customer would restrict
customer configurations and could easily exceed the VLAN limit (4096) of the IEEE 802.1Q specification. Using the QinQ
feature, service providers can use a single VLAN to support customers who have multiple VLANs. Customer VLAN IDs are
preserved, and traffic from different customers is segregated within the service-provider network, even when they appear to be in
the same VLAN. Using QinQ expands VLAN space by using a VLAN-in-VLAN hierarchy and retagging the tagged packets.
Virtual private networks (VPNs) provide enterprise-scale connectivity on a shared infrastructure, often Ethernet-based, with the
same security, prioritization, reliability, and manageability requirements of private networks. QinQ is a feature designed for
service providers who carry traffic of multiple customers across their networks and are required to maintain the VLAN and Layer

4.0.3.4 Port Mirroring
Port monitoring is a feature to redirect the traffic occurred on every port to a designated monitoring port on the IP DSLAM . With this
feature, the network administrator can monitor and analyze the traffic on the entire LAN segment. In NV-1602S, you can specify one
port to be the monitoring port and any single port to be the monitored port. You also can specify the direction of the traffic that
you want to monitor. After properly configured, packets with the specified direction from the monitored ports are forwarded to the
monitoring port.

4.0.3.5 Quality of Service
There are four transmission queues with different priorities in NV-1602S: Highest, SecHigh, SecLow and Lowest. The switch will
take packets from the four queues according to its QoS mode setting. If the QoS mode was set to “Disable”, the switch will not
perform QoS on its switched network. If the QoS mode was set to “High Empty Then Low”, the switch will never exhaust packets
from a queue until the queues with higher priorities are empty. If the QoS mode was set to “weight ratio”, the switch will exhaust
62
Page 64
NV-1602S 16 Ports VDSL2 Managed IP DSLAM with Redundant Power USER’S MANUAL Ver.A2
packets from the queues according to the ratio. The default value of QoS mode is “weight 8:4:2:1.” That means the switch will
first exhaust 8 packets from the queue with highest priority, and then exhaust 4 packets from the queue with second high priority,
and so on.
When the switch received a packet, the switch has to decide which queue to put the received packet into. In NV-1602S, the switch
will put received packets into queues according to the settings of “802.1p Priority” and “Static Port Ingress Priority.” When the
received packet is an 802.1p tagged packet, the switch will put the packet into a queue according to the 802.1p Priority setting.
Otherwise, the switch will put the packet into a queue according the setting of Static Port Ingress Priority.
802.1p Priority: the 802.1p packet has a priority tag in its packet header. The range of the priority is 7~0. The NV-1602S can
specify the mapping between 802.1p priority and the four transmission queues. In the default setting, the packets with 802.1p
priority 0~1 are put into the queue with lowest priority, the packets with 802.1p priority 2~3 are put into queue with second low
priority, and so on.
Static Port Ingress Priority: each port is assigned with one priority 7~0. The priority of the packet received from one port is set
to the same priority of the receiving port. When the priority of the received packet was determined, the packet is treated as an
802.1p packet with that priority and will be put into a queue according to the 802.1p Priority setting.
4.0.3.5.0 QoS Configuration
QoS Mode:
First Come First Service: The sequence of packets sent is depending on arrive orders.
All High before Low: The high priority packets sent before low priority packets.
WRR: Weighted Round Robin. Select the preference given to packets in the switch's high-priority queue. These options
represent the number of higher priority packets sent before one lower priority packet is sent.
63
Page 65
NV-1602S 16 Ports VDSL2 Managed IP DSLAM with Redundant Power USER’S MANUAL Ver.A2
For example, 8 Highest：4 second-high means that the switch sends 8 highest-priority packets before sending 4 second high
priority packets.
Qos Level: 0~7 priority level can map to highest, second-high, second-low, lowest queue.
Commands:
qos priority <first-come-first-service | all-high-before-low |weighted-round-robin> [<highest-weight>][<sechighweight>][<
sec low -weight>] [<lowest-weight>]
Set 802.1p priority.

4.0.3.7 MAC Limit
MAC limit allows users to set a maximum number of MAC addresses to be stored in the MAC address table. The MAC addresses
chosen to be stored in MAC address table is the result of first-come-first-save policy. Once a MAC address is stored in the MAC
address table, it stays in until it is aged out. When an “opening” is available, the switch stored the first new MAC address it sees in
that opening. All packets from MAC addresses not in the MAC address table should be blocked.
User can configure the MAC limit setting and fill in the new value.

4.0.4.5 DHCP Relay & Option 82
DHCP is widely used in LAN environments to dynamically assign host IP addresses from a centralized server, which significantly
reduces the overhead of administration of IP addresses. DHCP also helps conserve the limited IP address space because IP
addresses no longer need to be permanently assigned to hosts.
When the DHCP Option 82 feature is enabled on the switch, a subscriber device is identified by the switch port through which it
connects to the network (in addition to its MAC address). Multiple hosts on the subscriber LAN can be connected to the same port
on the access switch and are uniquely identified. Option82 Information is inserted by the switch enabled option-82 feature when
forwarding client-originated DHCP packets to a DHCP server (RFC 3046). Servers may use this information to implement IP
address or other parameter assignment policies. This will significantly enhance the security of DHCP and effectively prevent the
attack of DHCP flood.
91
Page 93
NV-1602S 16 Ports VDSL2 Managed IP DSLAM with Redundant Power USER’S MANUAL Ver.A2
The following figure is an example of DHCP Option 82:
If the DHCP relay feature is enabled on the switch, it forwards requests and replies between clients and servers when they are not
on the same physical subnet. Relay agent forwarding is different from the normal Layer 2 forwarding, in which IP datagrams are
switched transparently between networks. Relay agents receive DHCP messages and generate new DHCP messages to send on
output interfaces. So DHCP server can provide IP addresses to clients spanning multiple subnets instead of deploying a DHCP
server on every subnet.

4.0.4.6 LLDP
Link Layer Discovery Protocol (LLDP) operates on data link layer. It stores and maintains the information about the local device
and the devices directly connected to it for network administrators to manage networks through NMS (network management
systems). In LLDP, device information is encapsulated in LLDP PDUs in the form of TLV (meaning type, length, and value)
triplets and is exchanged between directly connected devices. Information in LLDP PDUs received is restored in its MIB.
Note:
Currently the LLDP neighbor(s) can be seen through the console only. SNMP browser will be supported in the future.
LLDP Operation Mode
LLDP can operate in one of the following modes.
LLDP Mode Description
TxRx mode A port in this mode sends and receives LLDP PDUs
Tx mode A port in this mode only sends LLDP PDUs
Rx mode A port in this mode only receives LLDP PDUs
Disable mode A port in this mode does not send or receive LLDP PDUs
LLDP is initialized when an LLDP-enabled port changes to operate in another LLDP operating mode. To prevent LLDP from
being initialized too frequently, LLDP undergoes a period before being initialized on an LLDP-enabled port when the port
changes to operate in another LLDP operating mode. The period is known as initialization delay, which is determined by the
re-initialization delay timer.
95
Page 97
NV-1602S 16 Ports VDSL2 Managed IP DSLAM with Redundant Power USER’S MANUAL Ver.A2
Sending LLDP PDUs
A LLDP-enabled device operating in the TxRx mode or Tx mode sends LLDP PDUs to its directly connected devices periodically.
It also sends LLDP PDUs when the local configuration changes to inform the neighboring devices of the change timely. In any of
the two cases, an interval exists between two successive operations of sending LLDP PDUs. This prevents the network from being
overwhelmed by LLDP PDUs even if the LLDP operating mode changes frequently.
To enable the neighboring devices to be informed of the existence of a device or an LLDP operating mode change (from the
disable mode to TxRx mode, or from the Rx mode to Tx mode) timely, a device can invoke the fast sending mechanism. In this
case, the interval to send LLDP PDUs changes to one second. After the device sends specific number of LLDP PDUs, the interval
restores to the normal. (A neighbor is discovered when a device receives an LLDPDU and no information about the sender is
locally available.)
Receiving LLDP PDUs
An LLDP-enabled device operating in the TxRx mode or Rx mode validates the TLVs carried in the LLDP PDUs which receive
and store the valid neighboring information. An LLDP PDU also carries a TTL (time to live) setting with it. The information about
a neighboring device maintained locally ages out when the corresponding TTL expires.
The TTL of the information about a neighboring device is determined by the following expression:
TTL = LLDP hold time × LLDP PDU sending interval (hello-time)
You can set the TTL by configuring the LLDP hold-time and hello-time. Note that the TTL can be up to 65535 seconds. TTL
longer than it will be rounded off to 65535 seconds.
