Safety Instructions
Use the following safety guidelines to ensure your own personal safety and to help protect your system from potential
damage. Throughout this safety section, the caution icon (
to be reviewed and followed.
Safety Cautions
To reduce the risk of bodily injury, electrical shock, fire, and damage to the equipment observe the f ol lowi ng
precautions:
• Observe and follow service markings.
• Do not service any product except as explained in the system documentation.
• Opening or removing covers that are marked with the triangular symbol with a lightning bolt may expose the
user to electrical shock.
o Only a trained service technician should service components inside these compartments.
• If any of the following conditions occur, unplug t he product from the electrical outlet and replace the part or
contact your trained service provider:
o Damage to the power cable, extension cable, or plug.
o An object has fallen into the product.
o The product has been exposed to water.
o The product has been dropped or damaged.
o The product does not operate correctly when t he operating instructions are correctly followed.
• Keep your system away from radiators and heat sou rces. Also, do not block cooling vents.
• Do not spill food or liquids on system components, and never operate the product in a wet environment. If the
system gets wet, see the appropriate section in the troubleshooting guide or contact your trained service
provider.
• Do not push any objects into the openings of the sy stem. Doing so can cause fire or electric shock by shorting
out interior components.
• Use the product only with approved equipment.
• Allow the product to cool before removing covers or touching internal components.
• Operate the product only from the type of external power source indicated on the electrical ratings label. If
unsure of the type of power source required, consult your service provider or local power company.
• To help avoid damaging the system, be sure the voltage selection switch (if provided) on the power supply is
set to match the power available at the Switch’s location:
o 115 volts (V)/60 hertz (Hz) in most of North and S outh America and some Far Eastern countries such
as South Korea and Taiwan
o 100 V/50 Hz in eastern Japan and 100 V/60 Hz in west ern Japan
o 230 V/50 Hz in most of Europe, the Middle East, and the Far East
• Also, be sure that attached devices are electri call y rated to operate with the power available in your location.
• Use only approved power cable(s). If you hav e not been provided with a power cable for your system or for any
AC-powered option intended for your system, purchase a power cable that is approved for use in your country.
The power cable must be rated for the product and for the voltage and current marked on the product's
electrical ratings label. The voltage and current rating of the cable should be greater than the ratings marked
on the product.
• To help prevent electric shock, plug the system and peripheral power cables into properly grounded electrical
outlets. These cables are equipped with three-prong plugs to help ensure proper grounding. Do not use
adapter plugs or remove the grounding prong from a cable. If using an extension cable is nece ss ary, use a 3wire cable with properly grounded plugs.
• Observe extension cable and power strip rati ngs. Make sure that the total ampere rating of al l products
plugged into the extension cable or power strip does not exceed 80 percent of the ampere rat ings l im i t for the
extension cable or power strip.
• To help protect the system from sudden, transient increases and decreases in electrical powe r, use a surge
suppressor, line conditioner, or uninterruptible power supply (UPS).

uncertain that suitable grounding is available.
• Position system cables and power cables carefully ; route cables so that they cannot be stepped on or t ripped
over. Be sure that nothing rests on any cable s.
• Do not modify power cables or plugs. Consult a lice nsed electrician or your power company for site
modifications. Always follow your local/n ational wiring rules.
• When connecting or disconnecting power to hot-pluggable power supplies, if offered with you r sy st em , observe
the following guidelines:
o Install the power supply before connecting the power cable to the power supply.
o Unplug the power cable before removing the power supply.
o If the system has multiple sources of power, disconnect power from the system by unplugging all
power cables from the power supplies.
• Move products with care; ensure that all caster s and/ or stabilizers are firmly connected to the sy stem. Avoid
sudden stops and uneven surfaces.
CAUTION: Risk of explosion if the battery is replaced by an incorrect battery type. Dispose of used
batteries according to the instructions.
ATTENTION: Risque d'explosion si la batterie est remplacée par un type incorrect. Jetez les piles
usagées selon les instructions.
如果更換不正確之電池型式會有爆炸的風險， 請依製造商說明書處理用過之電池。
General Precautions for Rack-Mountable Products
Observe the following precautions for rack st abi li ty and safety. Also, refer to the rack installation documentation
accompanying the system and the rack for specific caution statements and procedures.
• Systems are considered to be components in a ra ck. Thus, "component" refers to any system as well as to
various peripherals or supporting hardware.
CAUTION: Installing systems in a rac k wit hout the front and side stabilizers installed could cause the rack
to tip over, potentially resulting in bodily injury under certain circumstances. Therefore, always install the
stabilizers before installing components i n the rack. After installing system/components in a rack, never
pull more than one component out of the rack on its slide assemblies at one time. The weight of more t han
• Before working on the rack, make sure that the st abi l i zers are secured to the rack, extended to the floor, and
that the full weight of the rack rests on the f l oor. Install front and side stabilizers on a single rack or front
stabilizers for joined multiple racks befor e wor king on the rack.
• Always load the rack from the bottom up, and load the heaviest item in the rack first.
• Make sure that the rack is level and stable befor e extending a component from the rack.
• Use caution when pressing the component rail release latches and sliding a component into or out of a rack;
the slide rails can pinch your fingers.
• After a component is inserted into the rack, c arefully extend the rail into a locking position, and then slide the
component into the rack.
• Do not overload the AC supply branch circuit that provides power to the rack. The total rack load should not
exceed 80 percent of the branch circuit rating.
• Ensure that proper airflow is provided to comp onents in the rack.
• Do not step on or stand on any component when servicing other components in a rack.
NOTE: A qualified electrician must perform all connections to DC power and to safety grounds. All
electrical wiring must comply with applicabl e l ocal or national codes and practices.
CAUTION: Never defeat the ground conductor or operate the equipment in the absence of a suitably
installed ground conductor. Contact the appropriate electrical inspection authority or an el ectrician if

DGS-1510/ME Series Metro Ethernet Switch Web UI Reference Guide
ground cable is omitted or disconnected.
CAUTION: The system chassis must be positively grounded to the rack cabinet frame. Do not attempt to
connect power to the system until grounding cables are connected. Completed power and safety ground
wiring must be inspected by a qualified electrical i nspector. An energy hazard will exist if the safety
Protecting Against Electrostatic Discharge
Static electricity can harm delicate compone nts inside the system. To prevent static damage, di scharge static
electricity from your body before touching any of the electronic components, such as the microprocessor. This can be
done by periodically touching an unpainted met al surface on the chassis.
The following steps can also be taken prevent damage from electrostatic discharge (ESD):

Introduction
Most software functions of the DGS-1510/ME Series switches can be managed, configured and monitored via the
embedded web-based (HTML) interface. Manage the Switch from remote stations anywhere on t he network through a
standard browser. The browser acts as a universal access tool and can communicate directly with the Switch using
the HTTP protocol.
The Web-based management module and the Console program (and Telnet) are different ways t o acc ess the same
internal switching software and configure i t. Thus, all settings encountered in web-based manageme nt are the same
as those found in the console program.
Login to the Web Manager
To begin managing the Switch, simply run the brows er installed on your computer and point it to the IP address you
have defined for the device. The URL in the address b ar should read something like: http://123.123.123.123, where
the numbers 123 represent the IP address of the Switch.
NOTE: The factory default IP address is 10.90.90.90.
This opens the management module's user authentication window, as seen below.

PoE
The DGS-1510-28LP/ME and DGS-1510-28XMP/ME switches support Power over Ethernet (PoE) as defined by the
IEEE 802.3af and 802.3at standard. Ports 1 t o 24 for DGS-1510-28LP/ME and DGS-1510-28XMP/ME can supply
about 48 VDC power to Powered Devices (PDs) over Category 5 or Category 3 UTP Ethernet cables.
The Switch follows the standard Power Sourcing Eq ui pment (PSE) pinout Alternative A, whereby power is sent out
over pins 1, 2, 3 and 6. The Switches work with all D-Link 802.3af capable devices.
The Switch includes the following PoE features:
• Auto-discovery recognizes the connection of a Powered Device (PD) and automatically sends power t o i t.
• The Auto-disable function will activate when the port current value exceeds 350mA or when a short happens.

Single IP Management
D-Link Single IP Management is a concept that wil l st ack switches together over Ethernet instead of using stacking
ports or modules. There are some advantages in implementing the “Single IP Management” feature:
• SIM can simplify management of small workgroups or wiring closets while scaling the network to handle
increased bandwidth demand.
• SIM can reduce the number of IP address needed i n your network.
• SIM can eliminate any specialized cables for stacking connectivity and remove the distance barriers that
typically limit your topology options when using ot her stacking technology.
Switches using D-Link Single IP Management (labeled here as SIM) must conform to the following rule s:
1. SIM is an optional feature on the Switch and can easily be enabled or disabled through the Command Line
Interface or Web Interface. SIM grouping has no effect on the normal operation of the Swit ch in the user’s
network.
39
DGS-1510/ME Series Metro Ethernet Switch Web UI Reference Guide
2. There are three classifications for switches using SIM. The Commander Switch (CS), which is the master
switch of the group, Member Switch (MS), whic h i s a switch that is recognized by the CS a member of a SIM
group, and a Candidate Switch (CaS), which is a S witch that has a physical link to the SIM group but has not
been recognized by the CS as a member of the SIM group.
3. A SIM group can only have one Commander Switch (CS).
4. A SIM group accepts up to 32 switches (numbere d 1-32), not including the Commander Switch (numbered 0).
5. Members of a SIM group cannot cross a router.
6. There is no limit to the number of SIM groups in the same IP subnet (broadcast domain); however a single
switch can only belong to one group.
7. If multiple VLANs are configured, the SI M group will only utilize the default VLAN on any switch.
8. SIM allows intermediate devices that do not sup port SIM. This enables the user to manage switches that are
more than one hop away from the CS.
The SIM group is a group of switches that are managed as a single entity. The Switch may take on three different
roles:
a. Commander Switch (CS) – This is a switch that has been manually configured as the controlling
device for a group, and takes on the following characteristics:
a. It has an IP Address.
b. It is not a command switch or member switch of another Single IP group.
c. It is connected to the member switches through its management VLAN.
b. Member Switch (MS) – This is a switch that has joined a single IP group and is accessible from the
CS, and it takes on the following characterist ics:
a. It is not a CS or MS of another IP group.
b. It is connected to the CS through the CS managem ent VLAN.
c. Candidate Switch (CaS) – This is a switch that is ready to join a SIM group but is not yet a member
of the SIM group. The Candidate Switch may j oin the SIM group of the Switch by manually configurin g
it to be a MS of a SIM group. A switch configured as a CaS is not a member of a SIM group and will
take on the following characteristics:
• It is not a CS or MS of another Single IP group.
• It is connected to the CS through the CS managem ent VLAN
The following rules also apply to the above roles:
1. Each device begins in a Candidate state.
2. CSs must change their role to CaS and then to MS, to become a MS of a SIM group. Thus, the CS canno t
directly be converted to a MS.
3. The user can manually configure a CS to become a CaS.
4. A MS can become a CaS by:
• Being configured as a CaS through the CS.
• If report packets from the CS to the MS time out.
5. The user can manually configure a CaS to become a CS
6. The CaS can be configured through the CS to become a MS.
After configuring one switch to operate as the CS of a SIM group, additional DGS-1510/ME Series switches may join
the group by manually configuring the Switch to be a MS. The CS will then serve as the in band entry point for access
to the MS. The CS’s IP address will become t he path to all MS’s of the group and the CS’s Administrator’s password,
and/or authentication will control access to all M S ’ s of the SIM group.
With SIM enabled, the applications in the CS will redirect the packet instead of executing the packets. The
applications will decode the packet from the adm i ni strator, modify some data, and then send it to the MS. After
execution, the CS may receive a response pac ket from the MS, which it will encode and send it back to the
administrator.
When a CaS becomes a MS, it automatically becomes a member of the first SNMP community (includes read/write
and read only) to which the CS belongs. However, if a MS has its own IP address, it can belong to SNMP
communities to which other switches in the group, including the CS, do not belong.

Upgrade to v1.61
To better improve SIM management, the DGS-1510/ME Series switches have been upgraded to version 1.61 in this
release. Many improvements have been made, including:
a. The Commander Switch (CS) now has the capability
to automatically rediscover member switches t hat
have left the SIM group, either through a reboot or
web malfunction. This feature is accomplishe d
through the use of Discover packets and
Maintenance packets that previously set SI M
members will emit after a reboot. Once a MS has had
its MAC address and password saved to the CS’s
database, if a reboot occurs in the MS, the CS will
keep this MS information in its database and w hen a
MS has been rediscovered, it will add the MS back
into the SIM tree automatically. No configuration will
be necessary to rediscover these switches.
There are some instances where pre-saved MS switches
cannot be rediscovered. For example, if t he S witch is still
powered down, if it has become the member of another group,
or if it has been configured to be a Commander Switch, the
rediscovery process cannot occur.

c. This version will support switch upload and downloads for firmware, configuration files and log files, as follows:
• Firmware – The switch now supports MS firmware downloads from a TFTP server.
• Configuration Files – This switch now supports downloading and uploading of configuration files both to
(for configuration restoration) and from (for configuration backup) MS’s, using a TFTP server.
• Log – The Switch now supports uploading MS l og files to a TFTP server.

SNMP Settings
Simple Network Management Protocol (SNMP) is an OSI Layer 7 (Application Layer) designed specifically for
managing and monitoring network devices. S NMP enables network management stations to read and modify the
settings of gateways, routers, switches, and other network devices. Use SNMP to configure system features for proper
operation, monitor performance and detect potential problems in the Switch, switch group or network.
Managed devices that support SNMP include software (referred to as an agent), which runs locally on t he device. A
defined set of variables (managed objects) is mai ntained by the SNMP agent and used to manage the de vice. These
objects are defined in a Management Inform ation Base (MIB), which provides a standard p resentation of the
information controlled by the on-board SNMP agent. SNMP defines both the format of the MIB specif ications and the
protocol used to access this information over t he network.
The Switch supports the SNMP versions 1, 2c, and 3. The three versions of SNMP vary in the level of security
provided between the management station and the network device.
In SNMPv1 and SNMPv2c, user authentication i s ac complished using ‘community strings’, which function like
passwords. The remote user SNMP application and the Switch SNMP must use the same community string. SNMP
packets from any station that has not been aut henticated are ignored (dropped).
The default community strings for the Switch used for SNMPv1 and SNMPv2c management acce ss a re:
2. public – Allows authorized management stations to retrieve M IB objects.
3. private – Allows authorized management stations to retrieve and modify MIB objects.
SNMPv3 uses a more sophisticated authentic ation process that is separated into two parts. The fi rst part is to
maintain a list of users and their attributes that are allowed to act as SNMP managers. The second part desc ribes
what each user on that list can do as an SNMP mana ger.
49
DGS-1510/ME Series Metro Ethernet Switch Web UI Reference Guide
SNMP State
Enable this option to use the SNMP feature.
The Switch allows groups of users to be listed and configured with a shared set of privileges. The SNMP version may
also be set for a listed group of SNMP managers. Thus, you may create a group of SNMP managers that are allowed
to view read-only information or receive traps u sing SNMPv1 while assigning a higher level of securit y to another
group, granting read/write privileges using SNMPv3.
Using SNMPv3 individual users or groups of SNMP managers can be allowed to perform or be re st ricted from
performing specific SNMP management funct i ons. The functions allowed or restricted are defined using the Object
Identifier (OID) associated with a specifi c MIB. An additional layer of security is available f or SNMPv3 in that SNMP
messages may be encrypted. To read more about how to configure SNMPv3 settings for the Switch read the next
section.
Traps
Traps are messages that alert network personnel of events that occur on the Switch. The event s can be as serious as
a reboot (someone accidentally turned OFF the Switch), or less serious like a port status change. The Switch
generates traps and sends them to the trap recipi ent (or network manager). Typical traps inclu de trap messages for
Authentication Failure, Topology Change and Broadcast\Multicast Storm.
MIBs
The Switch in the Management Information B ase (MIB) stores management and counter informati on. The Switch uses
the standard MIB-II Management Information Base m odul e. Consequently, values for MIB objects can be r etrieved
from any SNMP-based network management sof tware. In addition to the standard MIB-II, the Switch also supports its
own proprietary enterprise MIB as an extended Management Information Base. Specifying the MIB Object Identifier
may also retrieve the proprietary MIB. M IB values can be either read-only or read-write.
The Switch incorporates a flexible SNMP m anagement for the switching environment. SNMP m anagement can be
customized to suit the needs of the networks and the preferences of the network administrator. Use the SNMP V3
menus to select the SNMP version used for specif ic tasks.
The Switch supports the Simple Network Management Protocol (SNMP) versions 1, 2c, and 3 . The administrator can
specify the SNMP version used to monitor and control the Switch. The three versions of SNMP v ary in the level of
security provided between the management st ation and the network device.
SNMP settings are configured using the menus located on the SNMP V3 folder of the Web manager. Workstations on
the network that are allowed SNMP privileged access to the Switch can be restricted with the M anagement Station IP
Address menu.

Understanding IEEE 802.1p Priority
Priority tagging is a function defined by the IEE E 802.1p standard designed to provide a means of managing traffic on
a network where many different types of data m ay be transmitted simultaneously. It is intended to alleviate problems
associated with the delivery of time crit i cal data over congested networks. The quality of applicat ions that are
dependent on such time critical data, such as vi deo conferencing, can be severely and adversely affected by even
very small delays in transmission.
Network devices that are in compliance wit h the IEEE 802.1p standard have the ability to recognize the priority level of
data packets. These devices can also assign a priority label or tag to packets. Compliant device s can also strip priority
tags from packets. This priority tag determines t he packet’s degree of expeditiousness and determines the queue to
which it will be assigned.
Priority tags are given values from 0 to 7 with 0 being assigned to the lowest priority data and 7 assigne d to the
highest. The highest priority tag 7 is generally only used for data associated with video or audio applications, which
are sensitive to even slight delays, or for data from specified end users whose data transmissi ons warrant special
consideration.
The Switch allows you to further tailor how prio rity tagged data packets are handled on your network. Using queues to
manage priority tagged data allows you to specify its relative priority to suit the needs of your network. There may be
circumstances where it would be advantageous to group two or more di fferently tagged packets into the same queue.
Generally, however, it is recommended that the highest priority queue, Queue 7, be reserved f or data packets with a
priority value of 7. Packets that have not been give n any priority value are placed in Queue 0 and thus give n the
lowest priority for delivery.
Strict mode and weighted round robin system are employed on the Switch to determine the rate at which the queues
are emptied of packets. The ratio used for clearing t he queues is 4:1. This means that the highest pri ority queue,
Queue 7, will clear 4 packets for every 1 packet cleared from Queue 0.
Remember, the priority queue settings on the Switch are for all ports, and all devices connected to the Switch will be
affected. This priority queuing system will be especially beneficial if your network employs switches with the capability
of assigning priority tags.
VLAN Description
A Virtual Local Area Network (VLAN) is a network topology configured according to a logical scheme rathe r than the
physical layout. VLANs can be used to combine any collection of LAN segments into an autonomous user group that
appears as a single LAN. VLANs also logically segme nt the network into different broadcast domains so th at packets
are forwarded only between ports within the VLA N. Typically, a VLAN corresponds to a particular subnet, although not
necessarily.
VLANs can enhance performance by conserving bandwi dth, and improve security by limiting traffic to speci fic domains.
59
DGS-1510/ME Series Metro Ethernet Switch Web UI Reference Guide
A VLAN is a collection of end nodes grouped by logic instead of physical location. End nodes that frequentl y
communicate with each other are assigned to the same VLAN, regardless of where they are physically on the network.
Logically, a VLAN can be equated to a broadcast domain, because broadcast packets are forwarded t o only members
of the VLAN on which the broadcast was initiated.
Notes about VLANs on the Switch
• No matter what basis is used to uniquely i dentify end nodes and assign these nodes VLAN membe rship,
packets cannot cross VLANs without a netwo rk device performing a routing function between the VLANs.
• The Switch supports IEEE 802.1Q VLANs. Th e port untagging function can be used to remove the 802.1Q tag
from packet headers to maintain compatibili ty with devices that are tag-unaware.
• The Switch’s default is to assign all ports to a single 802.1Q VLAN named “default.”
• The “default” VLAN has a VID = 1.
• The member ports of Port-based VLANs may overlap, if desired.
IEEE 802.1Q VLANs
Some relevant terms:
• Tagging – The act of putting 802.1Q VLAN information i nto the header of a packet.
• Untagging – The act of stripping 802.1Q VLAN information out of the packet header.
• Ingress port – A port on a switch where packets are flowing into the Switch and VLAN decisions must be
made.
• Egress port – A port on a switch where packets are flowing out of the Switch, either to another switch or to an
end station, and tagging decisions must be made.
IEEE 802.1Q (tagged) VLANs are implemented on the Switch. 802.1Q VLANs require tagging, whic h enables them to
span the entire network (assuming all switches on the network are IEEE 802.1Q-compliant).
VLANs allow a network to be segmented in order t o reduce the size of broadcast domains. All packet s entering a
VLAN will only be forwarded to the stations (over IE EE 802.1Q enabled switches) that are members of that VLAN, and
this includes broadcast, multicast and uni cast packets from unknown sources.
VLANs can also provide a level of security t o your network. IEEE 802.1Q VLANs will only deliver packets between
stations that are members of the VLAN.
Any port can be configured as either tagging or untagging. The untagging feature of IEEE 802.1Q VLA Ns allows
VLANs to work with legacy switches that don’t recognize VLAN tags in packet headers. The tagging feature allows
VLANs to span multiple 802.1Q-compliant switches through a single physical connection an d al l ows Spanning Tree to
be enabled on all ports and work normally.
The IEEE 802.1Q standard restricts the forwarding of untagged packets to the VLAN the receiving port is a member of.

Figure 4-1 IEEE 802.1Q Packet Forwarding
The main characteristics of IEEE 802.1Q are as fol l ows:
1. Assigns packets to VLANs by filtering.
2. Assumes the presence of a singl e global spanning tree.
3. Uses an explicit tagging scheme with one-level t agging.
4. 802.1Q VLAN Packet Forwarding
5. Packet forwarding decisions are made based upo n the following three types of rules:
Ingress rules – rules relev ant to the classification of received frames bel ongi ng to a VLAN.
Forwarding rules b etween ports – decides whether to filter or forward the packet.
Egress rule s – determines if the packet must be sent tagged or untagged.
802.1Q VLAN Tags
The figure below shows the 802.1Q VLAN tag. There are four additional octets inserted after the source MAC address.
Their presence is indicated by a value of 0x8100 in t he EtherType field. When a packet’s EtherType field i s equal to
0x8100, the packet carries the IEEE 802.1Q/802.1p tag. The tag is contained in the following two octets and consists
of 3 bits of user priority, 1 bit of Canonical F ormat Identifier (CFI – used for encapsulating Token Ring packets so they
can be carried across Ethernet backbones), an d 12 bits of VLAN ID (VID). The 3 bits of user priority are used by
802.1p. The VID is the VLAN identifier and is used by the 802.1Q standard. Because the VID is 12 bits long, 4094
unique VLANs can be identified.
The tag is inserted into the packet header making the entire packet longer by 4 octets. All of the informat i on originally
contained in the packet is retained.

DGS-1510/ME Series Metro Ethernet Switch Web UI Reference Guide
Packets that are tagged (are carrying the 802. 1Q VID information) can be transmitted from one 802.1Q compliant
network device to another with the VLAN information intact. This allows 802.1Q VLANs to span network devices (and
indeed, the entire network, if all network devices are 802.1Q compliant).
Unfortunately, not all network devices are 802. 1Q compliant. These devices are referred to as tag-unaware. 802.1Q
devices are referred to as tag-aware.
Prior to the adoption of 802.1Q VLANs, port-based and MAC-based VLANs were in common use. These VLANs reli ed
upon a Port VLAN ID (PVID) to forward packets. A packet received on a given port would be assigned that port’s PVID
and then be forwarded to the port that correspon ded to the packet’s destination address (found in the Switch’s
forwarding table). If the PVID of the port that received the packet is different from the PVID of the port that is to
transmit the packet, the Switch will drop the packet.
Within the Switch, different PVIDs mean di fferent VLANs (remember that two VLANs cannot com m unicate without an
external router). So, VLAN identification based upon the PVIDs cannot create VLANs that extend outside a given
switch (or switch stack).
Every physical port on a switch has a PVID. 802.1Q ports are also assigned a PVID, for use within the S witch. If no
VLANs are defined on the Switch, all ports are then assigned to a default VLAN with a PVID equal to 1. Untagged
packets are assigned the PVID of the port on which t hey were received. Forwarding decisions are based upon this
PVID, in so far as VLANs are concerned. Tagged packets are forwarded according to the VID contained within the tag.
Tagged packets are also assigned a PVID, but the PVID is not used to make packet-forwarding decisions, the VID is.
Tag-aware switches must keep a table to relate P V IDs within the Switch to VIDs on the network. The S witch will
compare the VID of a packet to be transmitt ed to the VID of the port that is to transmit the packet . If the two VIDs are
different, the Switch will drop the packet. Because of the existence of the PVID for untagged packets and the VID for
tagged packets, tag-aware and tag-unaware network devices can coexist on the same network.
A switch port can have only one PVID, but can have as many VIDs as the Switch has memory in its VLAN t abl e to
store them.
Because some devices on a network may be tag-una ware, a decision must be made at each port on a tag-aware
device before packets are transmitted – should the packet to be transmitted have a tag or not? If the transmitting port
is connected to a tag-unaware device, the packet s hould be untagged. If the transmitting port is co nnected to a tagaware device, the packet should be tagged.
Tagging and Untagging
Every port on an 802.1Q compliant switch can be configured as tagging or untagging.
Ports with tagging enabled will put the VID numb er, priority and other VLAN information into the header of all packets
that flow into and out of it.
If a packet has previously been tagged, the port will not alter the packet, thus keeping the VLAN information intact.
Other 802.1Q compliant devices on the netwo rk t o make packet-forwarding decisions can then use the VL AN
information in the tag.
Ports with untagging enabled will strip the 802.1Q tag from all packets that flow into and out of those ports. If the
packet doesn’t have an 802.1Q VLAN tag, t he port will not alter the packet. Thus, all packets receiv ed by and
forwarded by an untagging port will have no 802.1 Q VLAN information. (Remember that the PVID is only used
internally within the Switch). Untagging is used to send packets from an 802.1Q-compliant network device to a noncompliant network device.
Ingress Filtering
A port on a switch where packets are flowing into t he Switch and VLAN decisions must be made is referred to as an
ingress port. If ingress filtering is enabled f or a port , the Switch will examine the VLAN information in the packet
header (if present) and decide whether or not t o forward the packet.
If the packet is tagged with VLAN informat i on, the ingress port will first determine if the ingress port itself is a member
of the tagged VLAN. If it is not, the packet wil l be dropped. If the ingress port is a member of the 802.1Q VLAN, the

Switch then determines if the destination port i s a m ember of the 802.1Q VLAN. If it is not, the packet is dropped. If
the destination port is a member of the 802.1Q VLA N, the packet is forwarded and the destination port transmits it to
its attached network segment.
If the packet is not tagged with VLAN informati on, the ingress port will tag the packet with its own P VID as a VID (if the
port is a tagging port). The switch then determines if the destination port is a member of the same V LAN (has the
same VID) as the ingress port. If it does not, the packet is dropped. If it has the same VID, the packet is f orwarded and
the destination port transmits it on its attached network segment.
This process is referred to as ingress filtering and is used to conserve bandwidth within the Switch by dr opping
packets that are not on the same VLAN as the ingres s port at the point of reception. This eliminates the sub sequent
processing of packets that will just be dropped by the destination port.
Default VLANs
The Switch initially configures one VLAN, VID = 1, called “default.” The factory default setting as signs all ports on the
Switch to the “default.” As new VLANs are confi gured in Port-based mode, their respective member ports are removed
from the “default.”
Packets cannot cross VLANs. If a member of one VLA N wants to connect to another VLAN, the link must be through
an external router.
NOTE: If no VLANs are configured on the Switch, then all packets will be forwarded to any destination
port. Packets with unknown source addresses will be flooded to all ports. Broadcast and multicast
An example is presented below:
VLAN Name VID Switch Ports
Port-based VLANs
Port-based VLANs limit traffic that flows into and out o f switch ports. Thus, all devices connected to a port are
members of the VLAN(s) the port belongs to, whether there is a single computer directly connect ed to a switch, or an
entire department.
On port-based VLANs, NICs do not need to be able to identify 802.1Q tags in packet headers. NICs send and receive
normal Ethernet packets. If the packet’s dest i nation lies on the same segment, communications take place using
normal Ethernet protocols. Even though t hi s is always the case, when the destination for a packet li es on another
switch port, VLAN considerations come i nto play to decide if the packet gets dropped by the S witch or delivered.
VLAN Segmentation
Take for example a packet that is transmit ted by a machine on Port 1 that is a member of VLAN 2. If the destination
lies on another port (found through a normal for warding table lookup), the Switch then looks to see if the other port
(Port 10) is a member of VLAN 2 (and can therefore receive VLAN 2 packets). If Port 10 is not a member of VLAN 2,
then the packet will be dropped by the Switch and will not reach its destination. If Port 10 is a member of V LAN 2, the
packet will go through. This selective forwar di ng feature based on VLAN criteria is how VLANs segment networks.
The key point being that Port 1 will only transmit on VLA N 2.

QinQ
Double or Q-in-Q VLANs allow network providers to expand t heir VLAN configurations to place customer VLA Ns
within a larger inclusive VLAN, which adds a new layer to the VLAN configuration. This basically lets large ISP's
create L2 Virtual Private Networks and also cre ate transparent LANs for their customers, which will connect two or
more customer LAN points without over-compli cat i ng configurations on the client's side. Not only will overcomplication be avoided, but also now the administrator has over 4000 VLANs in which over 4000 VLANs can be
placed, therefore greatly expanding the VLAN network and enabling greater support of customers utilizing multiple
VLANs on the network.
Double VLANs are basically VLAN tags placed within existing IEEE 802.1Q VLANs which we will call SPVIDs (Service
Provider VLAN IDs). These VLANs are marked by a TPID (Tagged Protocol ID), configured in hex form to be
encapsulated within the VLAN tag of the packet. This identifies the packet as double-tagged and segre gates it from
other VLANs on the network, therefore creating a hierarchy of VLANs within a single packet.

In this example, the Service Provider Ac cess Network switch (Provider edge switch) is the device creating and
configuring Double VLANs. Both CEVLANs (Cu st omer VLANs), 10 and 11, are tagged with the SPVID 100 on the
Service Provider Access Network and therefore belong to one VLAN on the Service Provider’s network, thus being a
member of two VLANs. In this way, the Cust om er can retain its normal VLAN and the Service Provider can
congregate multiple Customer VLANs withi n one SPVLAN, thus greatly regulating traffic and r outing on the Service
Provider switch. This information is then rout ed to the Service Provider’s main network and regarded there as one
VLAN, with one set of protocols and one routing behavior.
Regulations for Double VLANs
Some rules and regulations apply with the implementation of the Double VLAN procedure.
• All ports must be configured for the SPVID and i ts corresponding TPID on the Service Provider’s edge
switch.
• All ports must be configured as Access Ports or Uplink ports. Access ports can only be Ethernet ports
while Uplink ports must be Gigabit ports.
• Provider Edge switches must allow frames of at least 1522 bytes or more, due to the addition of the SPVID
tag.
• Access Ports must be an un-tagged po rt of the service provider VLANs. Uplink Ports must be a tagged port
of the service provider VLANs.
• The switch cannot have both double and normal VLANs co-existing. Once the change of VLAN is made, all
Access Control lists are cleared and must be reconfigured.
• Once Double VLANs are enabled, GVRP must be disabled.
• All packets sent from the CPU to the Access ports must be untagged.
• The following functions will not operate when the switch is in Double VLAN mode:
o Guest VLANs.
o Web-based Access Control.
o IP Multicast Routing.
o GVRP.
o All Regular 802.1Q VLAN functions.

Spanning Tree
This Switch supports three versions of the Spanning Tree Protocol: 802.1D-1998 STP, 802.1D-2004 Rapid STP, and
802.1Q-2005 MSTP. 802.1D-1998 STP will be familiar to most networking professionals. However, since 802.1D-2004
RSTP and 802.1Q-2005 MSTP have been recently introduced to D-Link managed Ethernet switches, a brief
introduction to the technology is provided bel ow followed by a description of how to set up 802.1D-1998 STP, 802.1D2004 RSTP, and 802.1Q-2005 MSTP.
802.1Q-2005 MSTP
Multiple Spanning Tree Protocol, or MSTP, i s a st andard defined by the IEEE community that allows mult ipl e VLANs
to be mapped to a single spanning tree instance, which will provide multiple pathways across the network. Therefore,
these MSTP configurations will balance the traffic load, preventing wide scale disrupti ons when a single spanning tree
instance fails. This will allow for faster converg ences of new topologies for the failed instance. Fram es designated for
these VLANs will be processed quickly and complet ely throughout interconnected bridges utilizing any of the three
spanning tree protocols (STP, RSTP or MSTP).
An MSTI ID will classify these instances. M S T P wil l connect multiple spanning trees with a Common and Internal
Spanning Tree (CIST). The CIST will automaticall y determine each MSTP region, its maximum possible extent and
will appear as one virtual bridge that runs a single spanning tree. Consequentially, frames assi gned to different VLANs
will follow different data routes within adm i nist ratively established regions on the network, continuing to allow simple
and full processing of frames, regardless of adm i nistrative errors in defining VLANs and their respective spanning
trees.
Each switch utilizing the MSTP on a network will hav e a single MSTP configuration that will have the f ol l owing three
attributes:
1. A configuration name defined by an alphanumeri c st ring of up to 32 characters (defined in the MST
Configuration Identification window in the Configuration Name field).
2. A configuration revision number (named here as a Revision Level and found in the MST Configuration
Identification window) and;
3. A 4094-element table (defined here as a VID List in the MST Configuration Identification window), which
will associate each of the possible 4094 VLANs supported by the Switch for a given instance.
To utilize the MSTP function on the Switch, thre e st eps need to be taken:
1. The Switch must be set to the MSTP setting (foun d i n the STP Bridge Global Settings window in the STP
Version field)
2. The correct spanning tree priority for the M STP instance must be entered (defined here as a P riority in the
MSTI Config Information window when configuring MSTI ID settings).
3. VLANs that will be shared must be added to the MS T P Instance ID (defined here as a VID List in the MST
Configuration Identification window when configuring an MSTI ID settings).

802.1D-2004 Rapid Spanning Tree
The Switch implements three versions of t he S panning Tree Protocol, the Multiple Spanning Tree Protocol (MSTP) as
defined by the IEEE 802.1Q-2005, the Rapi d Spanning Tree Protocol (RSTP) as defined by the IEEE 802.1D-2004
specification and a version compatible wit h the IEEE 802.1D-1998 STP. RSTP can operate with legacy equipment
implementing IEEE 802.1D-1998; however the adv antages of using RSTP will be lost.
The IEEE 802.1D-2004 Rapid Spanning Tree Protocol (RSTP) evolved from the 802.1D-1998 STP standard. RSTP
was developed in order to overcome some limit ations of STP that impede the function of some recent switching
innovations, in particular, certain Layer 3 functions that are increasingly handled by Ethernet switches. The basic
function and much of the terminology is t he same as STP. Most of the settings configured for STP are also used for
RSTP. This section introduces some new Spanning Tree concepts and illustrates the main differen ces between the
two protocols.
Port Transition States
An essential difference between the three protocols is in the way ports transition to a forwarding state and in the way
this transition relates to the role of the port (f orwarding or not forwarding) in the topology. MSTP and RSTP combine
the transition states disabled, blocking and li st ening used in 802.1D-1998 and creates a single state Discarding. In
either case, ports do not forward packets. In the STP port transition states disabled, blocking or listening or in the
RSTP/MSTP port state discarding, there is no functional difference, the port is not active in the network topology.
Table 7-3 below compares how the three protocols differ regarding the port state transition.
All three protocols calculate a stable topology in the same way. Every segment will have a single path to the root
bridge. All bridges listen for BPDU packets. However, BPDU packets are sent more frequent ly - with every Hello
packet. BPDU packets are sent even if a BPDU packet was not received. Therefore, each link between bridges is
sensitive to the status of the link. Ultimat ely this difference results in faster detection of failed links, and thus faster
topology adjustment. A drawback of 802.1D-1998 is this absence of immediate feedback from adjacent bridges.
802.1Q-2005 MSTP 802.1D-2004 RSTP 802.1D-1998 STP Forwarding Learning
RSTP is capable of a more rapid transition to a forwarding state - it no longer relies on timer configurati ons - RSTP
compliant bridges are sensitive to feedback from ot her RSTP compliant bridge links. Ports do not need to wait for the
topology to stabilize before transitioning to a forwarding state. In order to allow this rapi d transition, the protocol
introduces two new variables: the edge port and the point-to-point (P2P) port.
Edge Port
The edge port is a configurable designat ion used for a port that is directly connected to a segment where a loop
cannot be created. An example would be a port conn ect ed directly to a single workstation. Ports that are designated
as edge ports transition to a forwarding state immediately without going through the listeni ng and learning states. An
edge port loses its status if it receives a BPDU pac ket, immediately becoming a normal spanning tree port.
P2P Port
A P2P port is also capable of rapid transition. P 2P ports may be used to connect to other bridges. Under RSTP/MSTP,
all ports operating in full-duplex mode are considered to be P2P ports, unless manually overridden t hrough
configuration.
802.1D-1998/802.1D-2004/802.1Q-2005 Compatibility
MSTP or RSTP can interoperate with legacy eq ui pment and is capable of automatically adjusting B P DU packets to
802.1D-1998 format when necessary. Howeve r, any segment using 802.1D-1998 STP will not benefit from the rapid
transition and rapid topology change detection of M STP or RSTP. The protocol also provides for a variable used for
migration in the event that legacy equipment on a segment is updated to use RSTP or MSTP.

Link Aggregation
Understanding Port Trunk Groups
Port trunk groups are used to combine a number of ports together to make a single high-bandwidth data pipeline. The
number of port trunk groups, supported by t he S witch, is equal to half of the total physical ports on the Switch. Each
port trunk group can have two to eight physical ports assigned to each g roup.
83
DGS-1510/ME Series Metro Ethernet Switch Web UI Reference Guide
4-27 Example of Port Trunk Group
The Switch treats all ports in a trunk group as a single port. Data transmitted to a specific host (dest ination address)
will always be transmitted over the same port in a t runk group. This allows packets in a data stream t o arrive in the
same order they were sent.
Link aggregation allows several ports to be grouped together and to act as a single link. This gives a ba ndwidth that is
a multiple of a single link's bandwidth.
Link aggregation is most commonly used to li nk a bandwidth intensive network device or devices, su ch as a server, to
the backbone of a network.
All of the ports in the group must be members of t he same VLAN, and their STP status, static multicast , traffic
segmentation and 802.1p default priority conf i gurations must be identical. Port locking, port mirroring, traffic control,
and 802.1X must not be enabled on the trunk group. Further, the LACP aggregated links must all be of the same
speed and should be configured as full duplex.
The Master Port of the group is to be configure d by the user, and all configuration options, includi ng the VLAN
configuration that can be applied to the Maste r P ort, are applied to the entire link aggregation group.
Load balancing is automatically applied to the port s in the aggregated group, and a link failure within the group causes
the network traffic to be directed to the remaining links in the group.

IGMP Snooping
Internet Group Management Protocol (IGMP) snooping allows the Switch to recognize IGMP queries and reports sent
between network stations or devices and an I G M P host . When enabled for IGMP snooping, the Switch ca n open or
close a port to a specific device based on IGMP messages passing through the Switch.
IGMP Snooping Settings
In order to use IGMP Snooping it must first be enabled for the entire Switch under IGMP Snooping Global Settings at
the top of the window. You may then fine-tune the set tings for each VLAN by clicking the corresponding Edit button.
When enabled for IGMP snooping, the Switch can open or close a port to a specific multicast group member based on
IGMP messages sent from the device to the IGMP host or vice versa. The Switch monitors IG M P m essages and
discontinues forwarding multicast packet s when there are no longer hosts requesting that they continue.
