• If any of the fo llowing cond itions occur , unplug the product from the electrical outlet and replace the part or contact your

trained service provider:

• Damage to the power cable, extension cable, or plug.

• An object has fallen into the prod uct.

• The product has been exposed to water.

• The product has been dropped or damaged.

• The product does not operate correctly when the operating instructions are correctly followed.

• Keep your system away from radiators and heat sources. Also, do not block cooling vents.

• Do not spill food or liquids on system components, and never operate t he produc t in a wet e nvironme nt. If the system gets

wet, see the appropriate section in the troubleshooting guide or contact your trained service provider.

• Do not push a ny objects int o the openin gs of the syste m. Doing so ca n cause fire or electri c shock by shor ting out int erior

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 lo c a tion:

• 115 volts (V)/60 hertz (Hz) in most of North and South America and some Far Eastern countries such as South Korea

and Taiwan

• 100 V/50 Hz in eastern Japan and 100 V/60 Hz in western Japan

• 230 V/50 Hz in most of Europe, the Middle East, and the Far East

• Also, be sure that attached devices are electrically rated to operate with the power available in your location.

• Use only approved power cable(s). If you have 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 necessary, use a 3-wire cable with properly grounded plugs.

• Observe extension cable and power strip ratings. Make sure that the total ampere rating of all products plugged into the

extension cable or power strip does not exceed 80 percent of the ampere ratings limit for the extension cable or power strip.

• To help protect the system from sudden, transient increases and decreases in electrical power, use a surge suppressor, line

conditioner, or uninterruptible power supply (UPS).

• Position system cables and power cables carefully; route cables so that they cannot be stepped on or tripped over. Be sure

that nothing rests on any cables.

• Do not modify power cables or plugs. Consult a licensed electrician or your power company for site modifications. Always

follow your local/national wiring rules.

• When connecting or disconnecting power to hot-pluggable power supplies, if offered with your system, observe the

following guidelines:

• Install the power supply before connecting the power cable to the power supply.

• Unplug the power cable before removing the power supply.

• If the system has multiple sources of power, disconnect power from the system b y unpluggi ng all power cables fro m

the power supplies.

• Move products with care; ensure that all casters and/or stabilizers are firmly connected to the system. Avoid sudden stops

and uneven surfaces.

General Precautions for Rack-Mountable Products

Observe the following precautions for rack stability 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 rack. Thus, "component" refers to any system as well as to various peripherals

or supporting hardware.

CAUTION: Installing s yste ms in a rack without t he f ront and s ide sta bilizers insta lled c ould cause the rack to t ip o ver , pote nti al l y resul tin g in bo di l y inj ury under certain circums tanc es . Therefore, always install the stabilizers before installing components in the rack. After installing system /components in a rack, never pul l more than one component out of th e rack on its slide assemblies at one time. The weig component could cause the rack to tip over and may result in serious injury.

• Before working on the rack, make sure that the stabilizers are secured to the rack, extended to the floor, and that the full

weight of the rack rests on the floor. Install front and side stabilizers on a single rack or front stab ilizers for joined multiple racks befor e working on the rack.

• Always load the rack from the bo ttom up, and load the heaviest item in the ra c k first.

• Make sure that the rack is level and stable before 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 finge r s.

• After a component is inserted into the rack, carefully 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 components 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 applicable local or national codes and practices.

CAUTION: Ne ver defeat the ground conductor or operate the equipm ent in the absence of a suitably installed ground conductor. Contact the appropriate electrical inspection authority or an electrician if uncertain that suitable grounding is available.

xiii

xStack® DGS-3200 Series Layer 2 Managed Gigabit Ethernet Switch Web UI Reference Guide

CAUTION: The s ystem chassis m ust be positively grounded to the rack cabine t 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 inspector. An energy hazard will exist if the safety ground cable is omitted or disconnected.

CAUTION: When mounting the Switch on a cement wall, a proper concrete sleeve anchor should be used, such as the one that is included in the optional D-Link Wall Mount kit (DRE-KIT018).

Lithium Batter y Precauti on

CAUTION: Incorrec tl y replac ing the lithi um batter y of the Switch m a y cause the bat tery to

explode. Replace this batter y only with the s ame or equi valent t ype recomm ended by the manufacturer. Discard used batteries according to the manufacturer’s instructions.

Protecting Against Electrostatic Discharge

Static electricity can harm delicate components inside the system. To prevent static da mage, dis charge 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 metal surface on the chassis.

The following steps can also be taken prevent damage from electrostatic discharge (ESD):

1. When unpacking a static-sensitive component from its shipping carton, do not remove the component from the antistatic

packing material until read y to install the component in the system. Just before un wrappi ng the anti static pac kaging, b e

sure to discharge static electricity from your body.

2. When transporting a sensitive component, first place it in an antistatic container or packaging.

3. Handle all sensitive compone nts in a static-safe area. If possible, use antistatic floor pads, workbench pads and an

antistatic grounding strap.

field.

xStack® DGS-3200 Series Layer 2 Managed Gigabit Ethernet Switch Web UI Reference Guide

4. If the Switch has no previously configured VLANs, the user can use the Management VLAN Name entitled “default”.

This defaul t Management VLAN contai ns all of the S witch ports a s members. I f the Switch has previousl y configured

VLANs, the user will need to enter the VLAN ID of the VLAN that conta ins the port connec ted to the manage ment

station that will access the Switch. T he Switch will allow management access from statio ns with the same VID listed

here.

NOTE: The Switch’s factory default IP address is 10.90.90.90 with a subnet mask of 255.0.0.0 and a default gateway of 0.0.0.0.

To use the DHCP or BOOTP protocols to assign the Switch an IP address, subnet mask, and default gateway address: Use the radio button at the top of the window to choose either DHCP or BOOTP. This selects the method the Switch assigns an IP

address on the next reboot. The following parameters may be configured or viewed:

Parameter Description Manual

DHCP

BOOTP

Subnet Mask

Gateway

Management VLAN Name

Allows the entry of an IP address, subnet mask, and a default gateway for the Switch. These fields should be of the form xxx.xxx.xxx.xxx, where each xxx is a number (represented in decimal form) between 0 and 255. This address should be a unique address on the network assigned for use by the network admini strator.

The Switch will send out a DHCP broadcast request when it is powered up. The DHCP protocol allows IP addresses, network masks, and default gateways to be assigned by a DHCP server. If this option is set, the Switch will first look for a DHCP server to provide it with this information before using the default or previously entered settings.

The Switch will send out a BOOTP broadcast request when it is powered up. The BOOTP protocol allows IP addresses, network masks, and default gateways to be assigned by a central BOOTP server. If this option is set, the Switch will first look for a BOOTP server to provide it with this information before using the default or previously entered settings.

A Bitmask that determines the extent of the subnet that the Switch is on. Should be of the form xxx.xxx.xxx.xxx, where each xxx is a number (represented in decimal) between 0 and 255. The value should be 255.0.0.0 for a Class A network, 255.255.0.0 for a Class B network, and

255.255.255.0 for a Class C network, but custom subnet masks are allowed. IP address that determines where packets with a destination address outside the current subnet

should be sent. This is usually the address of a router or a host acting as an IP gateway. If your network is not part of an intranet, or you do not want the Switch to be accessible outside your local network, you can leave this field unchanged.

This allows the entry of a VLAN name from which a management station will be allowed to manage the Switch using TCP/IP (in-band via Web manager or Telnet). Management stations that are on VLANs other than the one entered here will not be able to manage the Switch in-band unless their IP addresses are entered in the Trusted Host window (Security > Trusted Host). If VLANs have not yet been configured for the Switch, the default VLAN contains all of the Switch’s ports. There are no entries in the Trusted Host table, by default, so any management station that can connect to the Switch can access the Switch until a management VLAN is specified or Management Station IP addresses are assigned.

Click Apply to implement changes made.

Setting the Switch’s IP Address using the Console Interface

Each Switch must be assigned its own IP Address, which is used for communication with an SNMP network mana ger or othe r TCP/IP application (for example BO OTP, TFTP). The Switch’s default IP address is 10.90.90.90. The default Switch IP address can be changed to meet the specification of your networking address scheme.

xStack® DGS-3200 Series Layer 2 Managed Gigabit Ethernet Switch Web UI Reference Guide

The IP address for the Switch must be set be fore the Web-based manager can manage the switch. The Switch IP address can be automatically set using BOOTP or DHCP protocols, in which case the actual address assigned to the Switch must be known. The IP address may be set using the Command Line Interface (CLI) over the console serial port as follows:

• Starting at the command line prompt, enter the commands config ipif System ipaddress xxx.xxx.xxx.xxx/

yyy.yyy.yyy.yyy. Where the x’s represent the IP address to be assigned to the IP interface named System and the y’s

represent the corresponding subnet mask.

• Alternatively, the user can enter config ipif System ipaddress xxx.xxx.xxx.xxx/z. Where the x’s represent the IP

address to be assigned to the IP interface named System and the z represents the corresponding number of subnets in CIDR notation.

The IP interface named System on the Switch can be assigned an IP address and subnet mask, which can then be used to connect a management station to the Switc h’s Telnet or Web-based management agent.

Successful entry of the command will produce a “Success” message, indicating that the command execution was correctly. The user may now utilize this address to configure or manage the Switch through Telnet, the Command Line Interface (CLI) or the Web-based management (GUI).

The following parameters may be configured or viewed:

Parameter Description

From Port / To Port State Speed/Duplex

Use the drop-down menus to select the ports to be configured. Use the drop-down menu to enable or disable a given port or group of ports.

Toggle the Speed/Du plex field to either s elect the speed and duplex/half -duplex s tate of the port. Auto denotes auto-negotiation between 10 and 100 Mbps devices, in full- or halfduplex. The Auto s etting allows the port t o automatically determ ine the fastest settings the device the port is connected to can handle, and then to use those settings. The other options are 10M Half, 10M Full, 100M Half, 100M Full, 1000M Full_Master, 1000M Full_Slave, and 1000M Full. There is no automatic adjustment of port settings with any option other than Auto.

The Switch allows the user to configure three types of gigabit connections; 1000M Full_Master, 1000M Full_Slave, and 1000M Full. Gigabit connections only support full duplex connections and take on certain characteristics that are different from the other choices listed.

The 1000M Full_Master and 1000M Full_Slave parameters refer to connections running a 1000BASE-T cable for connection between the Switch port and other device capable of a gigabit connection. The master setting (1000M Full_Master) will allow the port to advertise capabilities related to duplex, speed and physical layer type. The master setting will also determine the master and slave relationship between the two connected physical layers. This relationship is necessary for establishing the timing control between the two physical layers. The timing control is set on a master physical layer by a local source. The slave setting (1000M Full_Slave) uses loop timing, where the timing comes from a data stream received from the master. If one connection is set for 1000M Full_Master, the other side of the connection must be set for 1000M Full_Slave. Any other configuration will result in a link down status for both ports.

SNMP Settings

Simple Network Management Protocol (SNMP) is an OSI Layer 7 (Application Layer) designed specifically for managing and monitoring network device s. SNMP enab les network mana gement statio ns to read and modi fy the settings of gateways, ro uters, 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 the device. A defined set of variables (managed objects) is maintained by the SNMP agent and used to manage the device. These objects are defined in a Management Information Base (MIB), which provides a standard presentation of the information controlled by the on-board SNMP agent. SNMP defines both the format of the MIB specifications and the protocol used to access this information over the 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 ne twork device.

In SNMP v.1 a nd v.2, us er authe ntica tion is ac compl ished using ‘c ommun ity strin gs’, which func tion like password s. The remote user SNMP application and the Switch SNMP must use the same community string. SNMP packets from any station that has not been authenticated are ignored (dropped).

The default community strings for the Switch used for SNMP v.1 and v.2 management access are:

• public – Allows authorized management stations to retrieve MIB objects.

• private – Allows authorized management stations to retr ieve and modify MIB objects.

xStack® DGS-3200 Series Layer 2 Managed Gigabit Ethernet Switch Web UI Reference Guide

SNMPv3 uses a more sophisticated authentication process that is separated into two parts. The first part is to maintain a list of users and their attributes that are allowed to act as SNMP managers. The second part describes what each user on that list can do as an SNMP manager.

The Switch al lows 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 using SNMPv1 while a ssign ing a higher l evel o f secur ity to anothe r gro up, gra ntin g read/ write privileges usin g S NMPv3.

Using SNMPv3 individual users or groups of SNMP managers can be allowed to perform or be restricted from performing specific SNMP management functions. The functions allowed or restricted are defined using the Object Identifier (OID) associated with a specific MIB. An additional layer of security is available for 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 events can be as serious as a reboot (someone accidentally turned OFF the Switch), or less serious like a port status c hange. The Switch generates traps and sends them to the tr ap r ec ip ie nt ( o r net work ma na ge r) . Typical traps include tr ap me ssa ge s fo r A uthe nt ication Failure, To po lo gy C ha nge and Broadcast\Multicast Storm.

MIBs

The Switch in the Management Information Base (MIB) stores management and counter information. The Switch uses the standard MIB-II Management Informatio n Ba se mod ule. Co nsequently, values for MIB objects can be retrieved from any SNMPbased network management software. In addition to the standard MIB-II, the Switch also supports its own p roprietary enterprise MIB as an extended Management Information Base. Specifying the MIB Object Identifier may also retrieve the proprietary MIB. MIB values can be either read-only or read-write.

The Switch incorp orate s a fle xible SNMP manage ment for the s witchi ng en viron ment. S NMP manage ment can b e cus tomize d 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 specific 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 vary in the level of security provided between the management station and the network device.

SNMP settings are configured using the menus located on the SNMP Settings folder of the Web manager. Wor kstations on the network that are allowed SNMP privileged access to the Switch can be restricted with the Management Station IP Address menu.

Single IP Management

Simply put, D -Link Single IP Management is a concept that will stack switches together over Ethernet instead of using stacking ports or modules. There are some advantages in implement ing the “Single IP Management” feature:

1. SIM can simplify management of small workgroups or wiring closets while scaling the network to handle increased

bandwidth demand.

2. SIM can reduce the number of IP address needed in your network.

3. SIM can eliminate any specialized cables for stacking connectivity and remove the distance barriers that typically limit

your topology options when using other stacking technology.

Switches using D-Link Single IP Management (labeled here as SIM) must conform to the following rules:

• 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 Switch in the user’s network.

• There are three classifications for switches using SIM. The Commander Switch ( CS), which is the master switch of the

group, Member Switch (MS), which is a switch that is recognized by the CS a member of a SIM group, and a Candidate Switch (Ca S), which is a Switch that has a physical link to the SIM group but has not been recognized by the CS as a member of the SIM group.

• A SIM group can only have one Commander Switch (CS).

xStack® DGS-3200 Series Layer 2 Managed Gigabit Ethernet Switch Web UI Reference Guide

• All switches in a particular SIM group must be in the same IP subnet (broadcast domain). Members of a SIM group

cannot cross a router.

• A SIM group accepts up to 32 switches (numbered 1-32), not including the Commander Switch (numbered 0).

• There is no l imit to t he number o f SIM group s in the sa me IP subnet (broadcast domain); however a single switch can

only belong to one group.

• If multiple VLANs are configured , the SI M group will only utilize the default VLAN on any switch.

• SIM allows intermediate devices that do not support SIM. This enables the user to manage switches that are more than

one hop awa y 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:

1. Commander Switch (CS) – T his is a switch that has been manually configured as the controlling device for a group, and

takes on the following characteristics:

• It has an IP Addre s s.

• It is not a command switch or member switch of another Single IP group.

• It is connected to the member switches through its management VLAN.

2. 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 characteristics:

• It is not a CS or MS of another IP group.

• It is connected to the CS through the CS management VL AN.

3. Candidate Switch (Ca S) – This is a switch that is ready to join a SIM gro up but i s not yet a member of the SIM group.

The Candid ate Switch may join the SIM group of the S witch by man ually confi guring it to be a MS of a SIM gr oup. 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 management VL AN

The following rules also apply to the above roles:

• Each device begins in a Candidate state.

• CS's must change their role to CaS and then to MS, to become a MS of a SIM group. Thus, the CS cannot directly be

converted to a MS.

• The user can manually configure a CS to become a CaS.

• 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.

• The user can manually configure a CaS to become a CS

• 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-3200 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 the path to all MS’s of the group and the CS’s Administrator’s password , and/or authentication will control access to all MS’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 administrator, modify some data, and then send it to the MS. After execution, the CS may receive a response packet 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 (including 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 i n the group, including the CS, do not belong.

Upgrade to v1.61

To better improve SIM manage ment, the DGS-320 0 Series switches have been upgraded to version 1.61 in this release. Many improvements have been made, including:

xStack® DGS-3200 Series Layer 2 Managed Gigabit Ethernet Switch Web UI Reference Guide

Commander – Choosing this parameter will make the Switch a Commander Switch (CS). The

4. The Commander Switch (CS) now has the capability to automatically rediscover member switches that have left the SIM

group, either through a reboot or web malfunction. This feature is accomplished through the use of Discover packets and Maintenance packets that previously set SIM 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 when 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 the Switch 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.

2. The topology map now includes new features for connections that are a member of a port trunking group. It will display the speed and number of Ethernet connections creating this por t trunk gro up, as shown in the adjacent picture.

5. This version will support s witch 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 log files to a TFTP server.

6. The user may zoom in and zoom out when utilizing the topology window to get a better, more defined view of the

configurations.

Understanding IEEE 80 2. 1 p Pri ority

Priority tagging is a function defined by the IEEE 802.1p standard designed to provide a means of managing traffic on a network where many different types of data may be transmitted simultaneously. It is int ended to alleviate pro blems associated with the delivery of time critical data over congested networks. The quality of applications that are dependent on such time critical data, such as video conferencing, can be severely and adversely affected by even very small delays in transmission.

Network devices that are in compliance with 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 devices can also strip priority tags from packets. This priority tag determines the 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 pr iority data and 7 assigned to the hi ghest. 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 transmissions warrant special consideration.

The Switch allows you to further tailor how priority tagged data packets are handled on your network. Us ing queues t o manage priority tagged data allows you to specify its relative priority to suit the needs of your networ k. There may be circumstances where it would be advantageous to group two or more differently tagged packets into the same queue. Generally, however, it is recommended t hat the highe st prio rity queue , Queue 7 , be reser ved for d ata packet s with a prio rity value o f 7. Pac kets that have not been given any priority value are placed in Queue 0 and thus given 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 the queues is 4:1. This means that the highest priority queue, Queue 7, will clear 4 packets for every 1 packet cleared from Queue 0.

Remember, the priority queue settings on the Switc h 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 rather 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 segment the network into different broadcast domains so that packets are forwarded only between ports within the VLAN. Typically, a VLAN corresponds to a particular subnet, although not necessarily.

xStack® DGS-3200 Series Layer 2 Managed Gigabit Ethernet Switch Web UI Reference Guide

VLANs can enhance performance by conserving bandwidth, and improve security by limiting traffic to specific domains. A VLAN is a collection of end nodes grouped by logic instead of physical location. End nodes that frequently 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 to 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 identify end nodes and assign these nodes VLAN membership, packets cannot

cross VLANs without a network device performing a routing function between the VLANs.

• The Switch supports IEEE 802.1Q VLANs. The port untaggi ng function can be used to remove the 802.1Q tag from

packet headers to maintain compatibility 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 into 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 s witch where packets are flowing out of t he 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 taggin g, which ena bles the m 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 to reduce the size of broadcast domains. All packets entering a VLAN will only be forwarded to the stations (over IEEE 802.1Q enabled switches) that are members of that VLAN, and this includes broadcast, multicast and unicast packets from unknown sources.

VLANs can also provide a level of security to your network. IEEE 802.1Q VLANs will only deliver packets b et ween statio ns that are members of the VLAN.

Any port can be configured as either tagging or untagging. The untagging feature of IEEE 802.1Q VLANs allows VLANs to work with legacy switches that don’t reco gnize VLAN tags in packet headers. The tagging feature allows VLANs to span multiple

802.1Q-compliant switches through a single physical connection and allows 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. The main characteristics of IEEE 802.1Q are as follows:

• Assigns packets to VLANs by filtering.

• Assumes the presence of a single global spanning tree.

• Uses an expli cit tagging scheme with one-level tagging.

• 802.1Q VLAN Packet Forwarding

• Packet forwarding decisions are made based upon the following three types of rules:

• Ingress rules – rules relevant to the classification of received frames belonging to a VLAN.

• Forwarding rules between ports – decides whether to filter or forward the packet.

• Egress rules – determines if the packet must be sent tagged or untagged.

xStack® DGS-3200 Series Layer 2 Managed Gigabit Ethernet Switch Web UI Reference Guide

Figure 3 - 1. IEEE 802.1Q Packet Forwarding

802.1Q VLAN Tags

The figure be low shows the 802.1 Q VLAN tag. There are four additional octets inserted after the source MAC address. Their presence is indicated by a value of 0x8100 in the EtherType field. When a packet’s EtherType field is 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 Format Identifier (CFI – used for encap sula tin g T oke n Ring packets so they can be carried across Ethernet backbones), and 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 i nformation origi nally contained

in the packet is retained.

Figure 3 - 2. IEEE 802.1Q Tag

xStack® DGS-3200 Series Layer 2 Managed Gigabit Ethernet Switch Web UI Reference Guide

The EtherType and VLAN ID are inserted after the MAC source address, but before the original EtherType/Length or Logical Link Control. Because the packet is now a bit longer than it was originally, the Cyclic Redundancy Check (CRC) must be recalculated.

Figure 3 - 3. Adding an IEEE 802.1Q Tag

Port VLAN ID

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 relied 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 corresponded 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 different VLANs (remember that two VLANs cannot communicate without an externa l 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 Switch. I f no VL ANs ar e 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 they 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 kee p a table to relate PVIDs within the Switch to VIDs on the network. T he Switch will compare the VID of a packet to be transmitted to the VID of the port that is to transmit the packet. If the t wo 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 table to store them. Because some devices on a network may be tag-unaware, 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 transmitti ng port is connected to a tagunaware device, the packet should be untagged. If the transmitting port is connected to a tag-aware 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 number, pr iority and other VL AN information into the heade r of all packets that flo w

into and out of it. If a packet has previously been tagged, the port will not alter the packet, thus keeping the VLAN information

xStack® DGS-3200 Series Layer 2 Managed Gigabit Ethernet Switch Web UI Reference Guide

intact. Other 802.1Q compliant devices on the network to make packet-forwarding d ecis ions ca n then use the VL AN infor matio n in the tag.

Ports with untagging enabled will strip the 80 2.1Q tag from all packets that flow into and out of those po rts. If the packet doesn’t have an 802.1Q VLAN tag, the port will not alter the packet. Thus, all packets received by and forwarded by an untagging port will have no 8 02. 1Q VLAN i nfor mation. (Re membe r that t he PVI D is onl y used i nterna lly wit hin the Swit ch). Untagg ing is u sed to send packets from an 802.1Q-compliant network device to a non-compliant network device.

Ingress Filtering

A port on a switch where packets are flowing into the Switch and VLAN decisions must be made is referred to as an ingress port. If ingress filtering is enabled for a port, the Switch will examine the VLAN information in the packet header (if present) and decide whether or not to forward the packet.

If the packet is tagged with V LAN information, the ingress po rt will first determine if the ingress por t itself is a member of the tagged VLAN. If it is not, the packet will be dropped. If the ingress port is a member of the 802.1Q VLAN, the Switch then determines if the destination port is a member of the 802.1Q VLAN. If it is not, the packet is dropped. If the destination port is a member of the 802.1Q VLAN, the packet is forwarded and the destination port transmits it to its attached network segment.

If the packet is not tagged with V LAN infor mation, the ingre ss port will tag the packet with its o wn PVID as a VI D (if the p ort is a tagging port). The switch then determines if the destination port is a member of the same VLAN (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 forwarded 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 b y dropping packets that are not on the same VL AN as t he ingres s po rt a t the p oi nt of re ception. This eliminates the subsequent 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 assigns all ports on the Switch to the “default.” As new VLANs are configured in Port-based mode, their respective member ports are removed from the “default.”

Packets cannot cross VLANs. If a member of one VLAN 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 pack ets will be forwarded to any destination port. Packets with unknown source addresses will be flooded to all ports. Broadcast and multicast packets will also be flooded to all ports.

An example is presented be low:

Table 3 - 1. VLAN Example – Assigned Ports

Port-based VLANs

Port-based VLANs limit traffic that flows into a nd out of switch ports. Thus, all de vices connected to a port are members of the VLAN(s) the port belongs to, whether there is a single computer directly connected 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 destination lies on the same segment, communications take place using normal Ethernet protocols. Even though this is always the case, when the destination for a packet lies on another switch port, VLAN considerations come into play to decide if the packet gets dropped by the Switch or delivered.

xStack® DGS-3200 Series Layer 2 Managed Gigabit Ethernet Switch Web UI Reference Guide

VLAN Segmentation

Take for example a packet that is transmitted by a machine on Port 1 that is a member of VLAN 2. If the destination lies on another port (found through a normal forwarding 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 Por t 10 is a member of VLAN 2, the packet will go through. This selective forwarding feature based on VLAN criteria is how VLANs segment networks. The key point being that Port 1 will only transmit on VLAN 2.

VLAN and Trunk Groups

The members of a trun k group have the sa me VLAN s etting. Any VLAN se tting o n the membe rs of a t runk group will app ly to the other member ports.

NOTE: In order to use VLAN segmentation in conjunction with port trunk groups, first set the port trunk group(s), and then configure the VLAN settings. To change the port trunk grouping with VLANs already in place it is unnecessary to reconfigure the VLAN settings after changing the port trunk group settings. VLAN settings will automatically change in conjunction with the change of the port trunk group settings.

Parameter Description GVRP Global Settings From Port / To Port

PVID

GVRP

Click the radio buttons to enable or disable GVRP settings. Use the drop-down menus to select a range of ports that will be included in the Port-based

VLAN. This field is used to manually assign a PVID to a VLAN. The Switch's default is to assign all

ports to the default VLAN with a VID of 1.The PVID is used by the port to tag outgoing, untagged packets, and to make filtering decisions about incoming packets. If the port is specified to accept only tagged frames - as tagging, and an untagged packet is forwarded to the port for transmission, the port will add an 802.1Q tag using the PVID to write the VID in the tag. When the packet arrives at its destination, the receiving device will use the PVID to make VLAN forwarding decisions. If the port receives a packet, and Ingress filtering is Enabled, the port will compare the VID of the incoming packet to its PVID. If the two are unequal, the port will drop the packet. If the two are equal, the port will receive the packet.

The GARP VLAN Registration Protocol (GVRP) enables the port to dynamically become a member of a VLAN. GVRP is Disabled by default.

This field denotes the type of frame that will be accepted by the port. The user may choose between Tagged Only, which means only VLAN tagged frames will be accepted, and All, which mean both tagged and untagged frames will be accepted. All is enabled by default.

MAC-based VLAN Settings

Users can create new MAC-based VLAN entries and search, edit, and delete existing entries. When an entry is created for a port, the port will automatically become the untagged member port of the specified VLAN. When a static MAC-based VLAN entry is created for a user, the traffic from this user will be able to be serviced under the specified VLAN regardless of the authentication function operating on this port.

Private VLAN Settings

The Switch allows users to create private VLANs. A private VLAN divides the Layer 2 broadcast domain of a VLAN into subdomains and are particularly useful for service providers who need to assign a unique VLAN to each of their customers. Each subdomain is made up of several pairs of private VLANs, with each private VLAN pair consisting of a primary and secondary VLAN. All of the VLAN pairs in a private VLAN domain are members of the same primary VLAN. Each subdomain is identified using the secondary VLAN ID.

The diagram below illustrates the structure of a Private VLAN domain:

xStack® DGS-3200 Series Layer 2 Managed Gigabit Ethernet Switch Web UI Reference Guide

Figure 3 - 12. Private VLAN domain

The ports in a private VLAN can be one of the following three types:

Port Type Description

Promiscuous

Isolated

Community

A promiscuous port is a port that is a member of a primary VLAN that can communicate with all interfaces, including ports that have been configured as community and isolated ports on secondary VLANs that are associated with the primary VLAN.

An isolated port is used to describe a host port that is a member of an isolated secondary VLAN. An isolated port is completely isolated at Layer 2 from other ports within the same private VLAN domain, apart from promiscuous ports. All traffic destined to isolated ports is blocked, except for tr affic originating from promiscuous ports. An y traffic originating f rom an isolated port is only forwarded to promiscuous ports.

A community port is used to des cribe a host port th at is a mem ber of a community second ary VLAN. A community port can communicate with both ports that are members of the same community VLAN and promiscuous ports. Interfac es that are configured as comm unity ports are isolated at Layer 2 from all other interfaces that are members of a different community and from isolated ports that are members of the same private VLAN domain.

VLAN Trunk Settings

Enable VLAN on a port to allow frames belonging to unknown VLAN groups to pass through that port. This is useful if you want to set up VLA N groups on end devic es without having to c onfigure the same VLAN groups on intermed i ary devices.

Refer to the following figure for an illustrated example. Suppose you want to create VLAN groups 1 and 2 (V1 and V2) on devices A and B. Without a VLAN Trunk, you must first configure VLAN groups 1 and 2 o n all intermediary switc hes C, D and E; otherwise they will drop frames with unkno wn VLAN gr oup tags. Ho wever, wit h VLAN Tr unk enabled on a port(s) in each intermediary switch, you only need to create VLAN groups in the end devices (A and B). C, D and E automatically allow frames with VLAN group tags 1 and 2 (VLAN groups that are unknown to those switches) to pass through their VLAN trunking port(s).

Users can combine a number of VLAN ports together to create VLAN trunks.

MLD Snooping

MLD Snooping Settings

Multicast Listener Discovery (MLD) Snooping is an IPv6 function used similarly to IGMP snooping in IPv4. It is used to discover ports on a VLAN that are requesting multicast data. Instead of flooding all p orts on a selecte d VLAN with multicast traf fic, MLD snooping will only forward multicast data to ports that wish to receive this data through the use of queries and reports produced by the requesting ports and the source of the multicast traffic.

MLD snooping is accomplished through the examination of the layer 3 part of an MLD control packet transferred between end nodes and a MLD router. When the Switch discovers that this route is req uesting multicast traffic, it adds the port directly attached to it into the correct IPv6 multicast table, and begins the pro cess of forwarding multicast traffic to that port. This entry in the multicast routing table records the port, the VLAN ID, and the associated multicast IPv6 multicast group address, and then considers this port to be an active lis te ning port. The active listening ports are the only ones to rece ive multicast group data.

MLD Control Messages

Three types of messages are transferred between devices using MLD snooping. These three messages are all defined by four ICMPv6 packet headers, labeled 130, 131, 132, and 143.

1. Multicast Listener Query – Similar to the IGMPv2 Host Membership Query for IPv4, and labeled as 130 in the

ICMPv6 packet header, this message is sent by the router to ask if any link is requesting multicast data. There are two types of MLD query messages emitted by the router. The General Query is used to advertise all multicast addresses that are ready to send multicast data to all listening ports, and the Multicast Specific query, which advertises a specific multicast address that is also ready. These two types of messages are distinguished by a multicast destination address located in the IPv6 header and a multicast address in the Multicast Listener Query Message.

2. Multicast Listener Report, Version 1 – Comparable to the Host Membership Report in IGMPv2, and labeled as 131 in

the ICMP packet header, this message is sent b y the listening port to the Switch stating that it is interested in receivi ng multicast data from a multicast address in response to the Multicast Listener Query message.

3. Multicast Listener Done – Akin to the Leave Group Message in IGMPv2, and labeled as 132 in the ICMPv6 packet

header, this message is sent by the multicast listening port stating that it is no longer interested in receiving multic a st data from a specific multicast group address, therefor e stating that it is “done” with the multicast data from this addr ess. Once this message is received by the Switch, it will no longer forward multicast tra ffic fro m a specific multica st group addr ess to this listening port.

4. Multicast Listener Report, Version 2 - Comparable to the Host Membership Report in IGMPv3, and labeled as 143 in

the ICMP packet header, this message is sent by the listening por t to the Switch stating t hat it is interested in re ceiving multicast data from a multicast address in response to the Multicast Listener Query message.

This parameter is used to specify the amount of time in seconds between general query transmissions. Default: 125 seconds.

This parameter is used to specify the maximum amount of time in seconds to wait for reports from listeners. Default: 10 seconds.

This parameter is used to provide fine-tuning that allows for expected packet losses on a subnet. The value of the robustness variable is used in calculating the following MLD message intervals:

• Group listener interval—Amount of time that must pass before a multicast router decides there are no more listeners of a group on a network. This interval is calculated as follows: (robustness variable * query interval) + (1 * query response interval).

• Other querier present interval—Amount of time that must pass before a multicast router decides that there is no longer another multicast router that is the querier. This interval is calculated as follows: (robustness variable * query interval) + (0.5 * query response interval).

• Last listener query count—Number of group-specific queries sent before the router assumes there are no local listeners of a group. The default number is the value of the robustness variable.

• By default, the robustness variab le is set to 2. You might want to increase this value if you expect a subnet to lose a high number of packets.
