Product Description
Cost-effective IPv6 Managed Gigabit Switch solution for SMB
Nowadays, lots of electronic products or mobile devices can browse the Internet, which means the need of IP Address increases.
However, the current IPv4 network infrastructure is not capable enough to provide IP Address to each single users/Clients. The
situation forces the ISP to build up the IPv6 (Internet Protocol version 6) network infrastructure speedily. To fulfill the demand,
IFS releases the IPv6 management Gigabit Ethernet Switch, IFS- series Managed Switch. It supports both IPv4 and IPv6
management functions. It can work with original network structure (IPv4) and also support the new network structure (IPv6) in the
future. With easy and friendly management interfaces and plenty of management functions included, the IFS- series Managed
Switch is the best choice for ISP to build the IPv6 FTTx edge service and for SMB to connect with IPv6 network.
High-Performance / Cost-effective / Telecom class Gigabit solution for Enterprise backbone and Data Center Networking
The IFS Managed Switch is a L2/L4 Managed Gigabit Switch. Since Gigabit network interface had become the basic equipment
and requirement of Enterprise and Network Servers, with 48Gbps switching fabric, the Managed Switch can handle extremely
large amounts of data in a secure topology linking to a backbone or high capacity servers. The powerful QoS and Network
Security features make it to meets the needs of effective data traffic control for both Campus and Enterprise, such VoIP, video
streaming and multicast application.
High Performance
The Managed Switch provides 24 10/100/1000Mbps (or 100/1000Mbps for GE-DSSG-244 fiber switch)
with 4 shared Gigabit SFP slots. It has a high performance switch architecture that is capable of providing non-blocking switch
fabric and wire-speed throughput as high as 48Gbps, which greatly simplifies the tasks of upgrading the LAN for catering to
increase bandwidth demands.
Robust Layer 2 Features
The Managed Switch can be programmed for basic switch management functions such as port speed configuration, Port
aggregation, VLAN, Spanning Tree protocol, QoS, bandwidth control and IGMP Snooping. The Managed Switch provides 802.1Q
Tagged VLAN, Q-in-Q VLAN trunning and private VLAN, the VLAN groups allowed on the Managed Switch will be maximally up to
255. Via supporting port aggregation, the Managed Switch allows the operation of a high-speed trunk combining multiple ports, up
to 12 Trunk groups, and up to 16 ports per trunk group, and it supports fail-over as well.
Excellent Traffic Control
The Managed Switch is equipped with powerful traffic management and QoS features to enhance services offered by telecoms.
The functionality includes QoS features such as wire-speed Layer 4 traffic classifiers and bandwidth limiting that are particular
useful for multi-tenant unit, multi business unit, Telco, or Network Service Provide applications. It also empowers the enterprises
to take full advantages of the limited network resources and guarantees the best performance at VoIP and Video conferencing
transmission.

Efficient Management
For efficient management, the series of Managed Switch is equipped with console, WEB and SNMP management interfaces. With
its built-in Web-based management, it offers an easy-to-use, platform-independent management and configuration facility. The
Managed Switch supports standard Simple Network Management Protocol (SNMP) and can be managed via any standard-based
management software. For text-based management, it can also be accessed via Telnet and the console port.
Powerful Security
The Managed Switch offers comprehensive Access Control List (ACL) for enforcing security to the edge. Its protection
mechanisms also comprise of port-based 802.1x and MAC-based user and device authentication. The port-security is effective in
limit the numbers of clients pass through, so that network administrators can now construct highly secured corporate networks
with time and effort considerably less than before.
Flexibility and Extension solution
The 4 mini-GBIC slots are compatible with 1000Base-SX/LX and WDM SFP (Small Factor Pluggable) fiber-optic modules. The
distance can be extended from 550 meters (Multi-Mode fiber) up to above 10/20/30/40/5060//70 kilometers (Single-Mode fiber or
WDM fiber). They are well suited for using within the enterprise data centers and distributions.
Reliable Stacking Management
The IFS Series Managed Switch provides a switch stacking function to manage up to 16 switches using a single IP address. That
helps network managers to easily configure switches via one single IP address instead of connecting and setting each unit one by
one. Through its high bandwidth tunnel and stacking technology, it gives enterprise, service provider and telcom flexible control
over port density, uplinks and switch stack performance. Up to 384 Gigabit Ethernet ports can be managed by a stacking group
and you can add ports and functionality as needed. The stacking technology also enables the advantages of chassis-based
switches to be integrated into IFS Series Managed Switch, but without the expensive up-front cost.
Advanced Features and Centralized Power Management for Enterprise and Campus PoE Networking (PoE Model)
The IFS GE-DSSG-244-POE and NS3601-24P/4S series PoE switches provides 24 10/100/1000Mbps Power-over-Ethernet (PoE,
IEEE 802.3af compliant) ports which optimize the installation and power management of network devices such as wireless access
points (AP), Voice over IP (VoIP) phones, and security video cameras. The PoE capabilities also help to reduce deployment costs
for network devices like the wireless AP as a result of freeing from restrictions of power outlet locations. Power and data switching
are integrated into one unit and delivered over a single cable. It thus eliminates cost for additional AC wiring and reduces
installation time.

Before attempting to connect stacking ports, verify that you have the required stack cables. The following cables are used to connect
stacked switches:
• NS-CBL-50: 50cm, Short stack cable –used to connect adjacent IFS switches.
• NS-CBL-200: 200cm, Long / Redundant stack cable – used to connect the top and bottom IFS switches of a stack.
There are two high-performance HDMI-like Stack ports on the rear panel for proprietary management stack. Only these IFS stacking
cables can be used for proper functionality.
STEP-1: Plug one end of the cable in the “STX1 / Cascade Down” port and the other end to the ”STX2 / Cascade UP” port of next
device.
STEP-2: Repeat the step for every device in the stack cluster, then ending at last switch.
STEP-3: If you wish to implement stack redundancy, use the long stack cable NS-CBL-200 to connect the stack port marked “STX1 /
Cascade Down” on the bottom switch to the port marked “STX2 / Cascade Up” on the top switch of the stack.
Figure 2-13 Stacking connection

IFS NS3601-24P/4S GE-DSSG-244 and 244-POE User Manual
The stack port is for management and data packets to be transmitted between other IFS stackable
switches, the stack ports can’t be configured with Layer 2 features via management interface.
STEP-4: Power up the stack switches.
Management Stacking
The stack operation of the IFS Managed Switch supports Plug and Play Stacking connection and auto stack configuration.
STEP-5: Once the stack start operation, the Stack master be automatically elected without any configuration required. The Stack
master is indicated by a green “Master” LED on the front panel. As the Figure 2-14.
Figure 2-14 Stack Master with “Master” LED lit
STEP-6: When an IFS Switch is added to the stack, a Switch ID is automatically assigned to the new IFS Switch. The automatic SID
assignment can be modified by choosing a different Switch ID on the Stack Configuration page. This method allows Switch
IDs to be assigned so that it is easier for the user to remember the ID of each switch.
STEP-7: Connect the RS-232 serial cable to the console port on the front of the stack master, then loin the IFS Switch to start the
switch management. The default IP address of the IFS Switch is 192.168.0.100.
1. The stack switch with least priority ID or MAC Address number will become Master. Only Master
switch’s management interface (console, telnet, web and SNMP) is accessible.

Management Access Overview
The Managed Switch gives you the flexibility to access and manage it using any or all of the following methods:
An administration console
Web browser interface
An external SNMP-based network management application
The administration console and Web browser interface support are embedded in the Managed Switch software and are available for
immediate use. Each of these management methods has their own advantages. Table 3-1 compares the three management
methods.
Method Advantages Disadvantages
Console
Web Browser
SNMP Agent
• No IP address or subnet needed
• Text-based
• Telnet functionality and HyperTerminal
built into Windows
95/98/NT/2000/ME/XP operating
systems
• Secure
• Ideal for configuring the switch remotely
• Compatible with all popular browsers
• Can be accessed from any location
• User friendly GUI
• Communicates with switch functions at
the MIB level
• Based on open standards
Table 3-1 Management Methods Comparison
• Must be near switch or use dial-up connection
• Not convenient for remote users
• Modem connection may prove to be unreliable
or slow
• Security can be compromised (hackers need
only know the IP address and subnet mask)
• May encounter lag times on poor connections
• Requires SNMP manager software
• Least visually appealing of all three methods
• Some settings require calculations
• Security can be compromised (hackers need
only know the community name)
Administration Console
The administration console is an internal, character-oriented, and command line user interface for performing system administration
such as displaying statistics or changing option settings. Using this method, you can view the administration console from a terminal,
personal computer, Apple Macintosh, or workstation connected to the switch's console (serial) port.
There are two ways to use this management method: via direct access or modem port access. The following sections describe
these methods. For more information about using the console, refer to Chapter 5 Command Line Interface Console
Management.
Figure 3-1 Console management
Direct Access
Direct access to the administration console is achieved by directly connecting a terminal or a PC equipped with a
terminal-emulation program (such as HyperTerminal) to the Managed Switch console (serial) port.
When using this management method, a straight DB9 RS-232 cable is required to connect the switch to the PC. After making
this connection, configure the terminal-emulation program to use the following parameters:
The default parameters are:
115200 bps
8 data bits
No parity
1 stop bit
33
IFS NS3601-24P/4S GE-DSSG-244 and 244-POE User Manual
Figure 3-2 Terminal parameter settings
You can change these settings, if desired, after you log on. This management method is often preferred because you can remain
connected and monitor the system during system reboots. Also, certain error messages are sent to the serial port, regardless of the
interface through which the associated action was initiated. A Macintosh or PC attachment can use any terminal-emulation program
for connecting to the terminal serial port. A workstation attachment under UNIX can use an emulator such as TIP.
Web Management
The Managed Switch offers management features that allow users to manage the Managed Switch from anywhere on the network
through a standard browser such as Microsoft Internet Explorer. After you set up your IP address for the switch, you can access the
Managed Switch's Web interface applications directly in your Web browser by entering the IP address of the Managed Switch.
You can then use your Web browser to list and manage the Managed Switch configuration parameters from one central location, just
as if you were directly connected to the Managed Switch's console port. Web Management requires either Microsoft Internet
Explorer 7.0 or later, Safari or Mozilla Firefox 3.0 or later.

Figure 3-4 Web main screen of Managed Switch
SNMP-Based Network Management
You can use an external SNMP-based application to configure and manage the Managed Switch, such as SNMPc Network Manager,
HP Openview Network Node Management (NNM) or What’s Up Gold. This management method requires the SNMP agent on the
switch and the SNMP Network Management Station to use the same community string. This management method, in fact, uses
two community strings: the get community string and the set community string. If the SNMP Net-work management Station only
knows the set community string, it can read and write to the MIBs. However, if it only knows the get community string, it can only
read MIBs. The default gets and sets community strings for the Managed Switch are public.

WEB CONFIGURATION
This section introduces the configuration and functions of the Web-Based management.
About Web-based Management
The Managed Switch offers management features that allow users to manage the Managed Switch from anywhere on the network
through a standard browser such as Microsoft Internet Explorer.
The Web-Based Management supports Internet Explorer 7.0. It is based on Java Applets with an aim to reduce network bandwidth
consumption, enhance access speed and present an easy viewing screen.
By default, IE7.0 or later version does not allow Java Applets to open sockets. The user has to
explicitly modify the browser setting to enable Java Applets to use network ports.
The Managed Switch can be configured through an Ethernet connection, make sure the manager PC must be set on same the IP
subnet address with the Managed Switch.
For example, the default IP address of the IFS Managed Switch is 192.168.0.100, then the manager PC should be set at
192.168.0.x (where x is a number between 1 and 254, except 100), and the default subnet mask is 255.255.255.0.
If you have changed the default IP address of the Managed Switch to 192.168.1.1 with subnet mask 255.255.255.0 via console,
then the manager PC should be set at 192.168.1.x (where x is a number between 2 and 254) to do the relative configuration on
manager PC.

When the mode is enabled, two ACEs are added automatically to trap UPNP
related packets to CPU. The ACEs are automatically removed when the mode is
disabled.
The TTL value is used by UPnP to send SSDP advertisement messages. Valid
values are in the range 1 to 255.
The duration, carried in SSDP packets, is used to inform a control point or control
points how often it or they should receive a SSDP advertisement message from
this switch. If a control point does not receive any message within the duration, it
will think that the switch no longer exists. Due to the unreliable nature of
the standard it is recommended that such refreshing of advertisements to be
done at less than one-half of the advertising duration. In the implementation, the
switch sends SSDP messages periodically at the interval one-half of the
advertising duration minus 30 seconds. Valid values are in the range 100 to
86400.

DHCP Relay
Configure DHCP Relay on this page. DHCP Relay is used to forward and to transfer DHCP messages between the clients and the
server when they are not on the same subnet domain.
The DHCP option 82 enables a DHCP relay agent to insert specific information into a DHCP request packets when forwarding client
DHCP packets to a DHCP server and remove the specific information from a DHCP reply packets when forwarding server DHCP
packets to a DHCP client. The DHCP server can use this information to implement IP address or other assignment policies.
Specifically the option works by setting two sub-options:
Circuit ID (option 1)
Remote ID (option2).
The Circuit ID sub-option is supposed to include information specific to which circuit the request came in on.
The Remote ID sub-option was designed to carry information relating to the remote host end of the circuit.
The definition of Circuit ID in the switch is 4 bytes in length and the format is "vlan_id" "module_id" "port_no". The parameter of
"vlan_id" is the first two bytes represent the VLAN ID. The parameter of "module_id" is the third byte for the module ID (in
standalone switch it always equal 0, in stackable switch it means switch ID). The parameter of "port_no" is the fourth byte and it
means the port number.
The Remote ID is 6 bytes in length, and the value is equal the DHCP relay agent’s MAC address. The DHCP Relay Configuration
screen is shown Figure 4-2-11.

Simple Network Management Protocol
SNMP Overview
The Simple Network Management Protocol (SNMP) is an application layer protocol that facilitates the exchange of management
information between network devices. It is part of the Transmission Control Protocol/Internet Protocol (TCP/IP) protocol suite. SNMP
enables network administrators to manage network performance, find and solve network problems, and plan for network growth.
An SNMP-managed network consists of three key components: Network management stations (NMSs), SNMP agents,
Management information base (MIB) and network-management protocol：
。 Network management stations (NMSs):Sometimes called consoles, these devices execute management applications that
monitor and control network elements. Physically, NMSs are usually engineering workstation-caliber computers with fast
CPUs, megapixel color displays, substantial memory, and abundant disk space. At least one NMS must be present in each
managed environment.
。 Agents：Agents are software modules that reside in network elements. They collect and store management information such
as the number of error packets received by a network element.
。 Management information base (MIB):A MIB is a collection of managed objects residing in a virtual information store.
Collections of related managed objects are defined in specific MIB modules.
。 Network-management protocol: A management protocol is used to convey management information between agents and
NMSs. SNMP is the Internet community's de facto standard management protocol.
SNMP Operations
SNMP itself is a simple request/response protocol. NMSs can send multiple requests without receiving a response.
。 Get -- Allows the NMS to retrieve an object instance from the agent.
。 Set -- Allows the NMS to set values for object instances within an agent.
。 Tra p -- Used by the agent to asynchronously inform the NMS of some event. The SNMPv2 trap message is designed to
replace the SNMPv1 trap message.
SNMP community
An SNMP community is the group that devices and management stations running SNMP belong to. It helps define where information
is sent. The community name is used to identify the group. A SNMP device or agent may belong to more than one SNMP community.
It will not respond to requests from management stations that do not belong to one of its communities. SNMP default communities
are:
。 Write = private
。 Read = public
Use the SNMP Menu to display or configure the Managed Switch's SNMP function. This section has the following items:

Configure port Mirroring on this page. This function provide to monitoring network traffic that forwards a copy of each incoming or
outgoing packet from one port of a network Switch to another port where the packet can be studied. It enables the manager to keep
close track of switch performance and alter it if necessary.
• To debug network problems, selected traffic can be copied, or mirrored, to a mirror port where a frame analyzer can be
attached to analyze the frame flow.
• The Managed Switch can unobtrusively mirror traffic from any port to a monitor port. You can then attach a protocol analyzer or
RMON probe to this port to perform traffic analysis and verify connection integrity.

Link Aggregation
Port Aggregation optimizes port usage by linking a group of ports together to form a single Link Aggregated Groups (LAGs). Port
Aggregation multiplies the bandwidth between the devices, increases port flexibility, and provides link redundancy.
Each LAG is composed of ports of the same speed, set to full-duplex operations. Ports in a LAG, can be of different media types
(UTP/Fiber, or different fiber types), provided they operate at the same speed.
Aggregated Links can be assigned manually (Port Trunk) or automatically by enabling Link Aggregation Control Protocol (LACP)
on the relevant links.
Aggregated Links are treated by the system as a single logical port. Specifically, the Aggregated Link has similar port attributes to a
non-aggregated port, including auto-negotiation, speed, Duplex setting, etc.
The device supports the following Aggregation links :
Static LAGs (Port Trunk) – Force aggregared selected ports to be a trunk group.
Link Aggregation Control Protocol (LACP) LAGs - LACP LAG negotiate Aggregated Port links with other LACP ports
located on a different device. If the other device ports are also LACP ports, the devices establish a LAG between them.
84
IFS NS3601-24P/4S GE-DSSG-244 and 244-POE User Manual
Figure 4-5-1 Link Aggregation
The Link Aggregation Control Protocol (LACP) provides a standardized means for exchanging information between Partner
Systems that require high speed redundant links. Link aggregation lets you group up to eight consecutive ports into a single
dedicated connection. This feature can expand bandwidth to a device on the network. LACP operation requires full-duplex mode,
more detail information refer to the IEEE 802.3ad standard.
Port link aggregations can be used to increase the bandwidth of a network connection or to ensure fault recovery. Link aggregation
lets you group up to 4 consecutive ports into a single dedicated connection between any two the Switch or other Layer 2 switches.
However, before making any physical connections between devices, use the Link aggregation Configuration menu to specify the link
aggregation on the devices at both ends. When using a port link aggregation, note that:
• The ports used in a link aggregation must all be of the same media type (RJ-45, 100 Mbps fiber).
• The ports that can be assigned to the same link aggregation have certain other restrictions (see below).
• Ports can only be assigned to one link aggregation.
• The ports at both ends of a connection must be configured as link aggregation ports.
• None of the ports in a link aggregation can be configured as a mirror source port or a mirror target port.
• All of the ports in a link aggregation have to be treated as a whole when moved from/to, added or deleted from a VLAN.
• The Spanning Tree Protocol will treat all the ports in a link aggregation as a whole.
• Enable the link aggregation prior to connecting any cable between the switches to avoid creating a data loop.
• Disconnect all link aggregation port cables or disable the link aggregation ports before removing a port link aggregation to
avoid creating a data loop.
It allows a maximum of 16 ports to be aggregated at the same time. The Managed Switch support Gigabit Ethernet ports (up to 12
groups). If the group is defined as a LACP static link aggregationing group, then any extra ports selected are placed in a standby
mode for redundancy if one of the other ports fails. If the group is defined as a local static link aggregationing group, then the
number of ports must be the same as the group member ports.
The aggregation code ensures that frames belonging to the same frame flow (for example, a TCP connection) are always forwarded
on the same link aggregation member port. Reording of frames within a flow is therefore not possible. The aggregation code is
based on the following information:
• Source MAC
85
IFS NS3601-24P/4S GE-DSSG-244 and 244-POE User Manual
• Destination MAC
• Source and destination IPv4 address.
• Source and destination TCP/UDP ports for IPv4 packets
Normally, all 5 contributions to the aggregation code should be enabled to obtain the best traffic distribution among the link
aggregation member ports. Each link aggregation may consist of up to 16 member ports. Any quantity of link aggregations may be
configured for the device (only limited by the quantity of ports on the device.) To configure a proper traffic distribution, the ports within
a link aggregation must use the same link speed.

VLAN
VLAN Overview
A Virtual Local Area Network (VLAN) is a network topology configured according to a logical scheme rather than the physical
layout. VLAN can be used to combine any collection of LAN segments into an autonomous user group that appears as a single LAN.
VLAN 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.
VLAN 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.
1. No matter what basis is used to uniquely identify end nodes and assign these nodes VLAN
membership, packets cannot cross VLAN without a network device performing a routing
function between the VLAN.
2. The Managed Switch supports IEEE 802.1Q VLAN. The port untagging function can be used
to remove the 802.1 tag from packet headers to maintain compatibility with devices that are
This section has the following items:
IEEE 802.1Q VLAN
IEEE 802.1Q Tunneling
Private VLAN
IEEE 802.1Q VLAN
tag-unaware.
3. The Switch's default is to assign all ports to a single 802.1Q VLAN named DEFAULT_VLAN.
As new VLAN is created, the member ports assigned to the new VLAN will be removed from
the DEFAULT_ VLAN port member list. The DEFAULT_VLAN has a VID = 1.
Enable IEEE 802.1Q Tag based VLAN group
Enables 802.1Q (QinQ) Tunneling
Creates/removes primary or community VLANs
In large networks, routers are used to isolate broadcast traffic for each subnet into separate domains. This Managed Switch
provides a similar service at Layer 2 by using VLANs to organize any group of network nodes into separate broadcast domains.
VLANs confine broadcast traffic to the originating group, and can eliminate broadcast storms in large networks. This also provides a
more secure and cleaner network environment.
An IEEE 802.1Q VLAN is a group of ports that can be located anywhere in the network, but communicate as though they belong to
the same physical segment.
VLANs help to simplify network management by allowing you to move devices to a new VLAN without having to change any
physical connections. VLANs can be easily organized to reflect departmental groups (such as Marketing or R&D), usage groups
(such as e-mail), or multicast groups (used for multimedia applications such as videoconferencing).
VLANs provide greater network efficiency by reducing broadcast traffic, and allow you to make network changes without having to
update IP addresses or IP subnets. VLANs inherently provide a high level of network security since traffic must pass through a
configured Layer 3 link to reach a different VLAN.
This Managed Switch supports the following VLAN features:
Up to 255 VLANs based on the IEEE 802.1Q standard
Distributed VLAN learning across multiple switches using explicit or implicit tagging and GVRP protocol
Port overlapping, allowing a port to participate in multiple VLANs
End stations can belong to multiple VLANs
Passing traffic between VLAN-aware and VLAN-unaware devices
Priority tagging
■ IEEE 802.1Q Standard
IEEE 802.1Q (tagged) VLAN are implemented on the Switch. 802.1Q VLAN require tagging, which enables them to span the entire
network (assuming all switches on the network are IEEE 802.1Q-compliant).
92
IFS NS3601-24P/4S GE-DSSG-244 and 244-POE User Manual
VLAN 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.
VLAN can also provide a level of security to your network. IEEE 802.1Q VLAN 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 VLAN allows VLAN to work with legacy switches that don't recognize VLAN tags in
packet headers.
The tagging feature allows VLAN 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.
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.
■ 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 the Ether Type field. When a packet's Ether Type 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 encapsulating Token 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 VLAN can be identified.
The tag is inserted into the packet header making the entire packet longer by 4 octets. All of the information originally contained in
the packet is retained.
802.1Q Tag

93
IFS NS3601-24P/4S GE-DSSG-244 and 244-POE User Manual
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 VLAN to span network devices (and indeed, the entire network – if all
network devices are 802.1Q compliant).
Every physical port on a switch has a PVID. 802.1Q ports are also assigned a PVID, for use within the switch. If no VLAN 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 they were received. Forwarding decisions are based upon this PVID, in so far as VLAN 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 PVID within the switch to VID on the network. The 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 two VID 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 VID 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 transmitting port is connected to a
tag-unaware device, the packet should be untagged. If the transmitting port is connected to a tag-aware device, the packet should
be tagged.
■ 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 VLAN are configured in Port-based mode, their respective member ports are removed from the "default."
■ Assigning Ports to VLANs
Before enabling VLANs for the switch, you must first assign each port to the VLAN group(s) in which it will participate. By default all
ports are assigned to VLAN 1 as untagged ports. Add a port as a tagged port if you want it to carry traffic for one or more VLANs,
and any intermediate network devices or the host at the other end of the connection supports VLANs. Then assign ports on the other
VLAN-aware network devices along the path that will carry this traffic to the same VLAN(s), either manually or dynamically using
GVRP. However, if you want a port on this switch to participate in one or more VLANs, but none of the intermediate network devices
nor the host at the other end of the connection supports VLANs, then you should add this port to the VLAN as an untagged port.
VLAN-tagged frames can pass through VLAN-aware or VLAN-unaware network interconnection
devices, but the VLAN tags should be stripped off before passing it on to any end-node host that
does not support VLAN tagging.
■ VLAN Classification
When the switch receives a frame, it classifies the frame in one of two ways. If the frame is untagged, the switch assigns the frame
to an associated VLAN (based on the default VLAN ID of the receiving port). But if the frame is tagged, the switch uses the tagged
VLAN ID to identify the port broadcast domain of the frame.
■ Port Overlapping
Port overlapping can be used to allow access to commonly shared network resources among different VLAN groups, such as file
servers or printers. Note that if you implement VLANs which do not overlap, but still need to communicate, you can connect them by
enabled routing on this switch.
■ Untagged VLANs
Untagged (or static) VLANs are typically used to reduce broadcast traffic and to increase security. A group of network users
assigned to a VLAN form a broadcast domain that is separate from other VLANs configured on the switch. Packets are forwarded
only between ports that are designated for the same VLAN. Untagged VLANs can be used to manually isolate user groups or
subnets.

VLAN Port Configuration
This page is used for configuring the Managed Switch port VLAN. The VLAN per Port Configuration page contains fields for
managing ports that are part of a VLAN. The port default VLAN ID (PVID) is configured on the VLAN Port Configuration page. All
untagged packets arriving to the device are tagged by the ports PVID.

■ IEEE 802.1Q Tagged and Untagged
Every port on an 802.1Q compliant switch can be configured as tagged or untagged.
• Tagged:
• Untagged:
Ports with tagging enabled will put the VID number, priority and other VLAN information into the
header of all packets that flow into those ports. If a packet has previously been tagged, the port
will not alter the packet, thus keeping the VLAN information intact. The VLAN information in the
tag can then be used by other 802.1Q compliant devices on the network to make
packet-forwarding decisions.
Ports with untagging enabled will strip the 802.1Q tag from all packets that flow into those
ports. 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 802.1Q 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 non-compliant network
device.

■ IEEE 802.1Q Tunneling (Q-in-Q)
IEEE 802.1Q Tunneling (QinQ) is designed for service providers carrying traffic for multiple customers across their networks. QinQ
tunneling is used to maintain customer-specific VLAN and Layer 2 protocol configurations even when different customers use the
same internal VLAN IDs. This is accomplished by inserting Service Provider VLAN (SPVLAN) tags into the customer’s frames
when they enter the service provider’s network, and then stripping the tags when the frames leave the network.
A service provider’s customers may have specific requirements for their internal VLAN IDs and number of VLANs supported. VLAN
ranges required by different customers in the same service-provider network might easily overlap, and traffic passing through the
infrastructure might be mixed. Assigning a unique range of VLAN IDs to each customer would restrict customer configurations,
require intensive processing of VLAN mapping tables, and could easily exceed the maximum VLAN limit of 4096.
The Managed Switch supports multiple VLAN tags and can therefore be used in MAN applications as a provider bridge, aggregating
traffic from numerous independent customer LANs into the MAN (Metro Access Network) space. One of the purposes of the
provider bridge is to recognize and use VLAN tags so that the VLANs in the MAN space can be used independent of the customers’
VLANs. This is accomplished by adding a VLAN tag with a MAN-related VID for frames entering the MAN. When leaving the MAN,
the tag is stripped and the original VLAN tag with the customer-related VID is again available.
This provides a tunneling mechanism to connect remote costumer VLANs through a common MAN space without interfering with
the VLAN tags. All tags use EtherType 0x8100 or 0x88A8, where 0x8100 is used for customer tags and 0x88A8 are used for service
provider tags.
In cases where a given service VLAN only has two member ports on the switch, the learning can be disabled for the particular VLAN
and can therefore rely on flooding as the forwarding mechanism between the two ports. This way, the MAC table requirements is
reduced.

Allow assign PVID for selected port. The range for the PVID is 1-4094.
The PVID will be inserted into all untagged frames entering the ingress port. The
PVID must as same as the VLAN ID that the port belong to VLAN group, or the
untagged traffic will be dropped.
Enable ingress filtering for a port by checking the box. This parameter affects
VLAN ingress processing. If ingress filtering is enabled and the ingress port is not
a member of the classified VLAN of the frame, the frame is discarded. By default,
ingress filtering is disabled (no checkmark).
Determines whether the port accepts all frames or only tagged frames. This
parameter affects VLAN ingress processing. If the port only accepts tagged
frames, untagged frames received on the port are discarded. By default, the field
is set to All.
Allow 802.1Q Untagged or Tagged VLAN for selected port.
When adding a VLAN to selected port, it tells the switch whether to keep or
remove the tag from a frame on egress.
- Untag: outgoing frames without VLAN-Tagged.
- Tagged: outgoing frames with VLAN-Tagged.
Sets the Managed Switch to QinQ mode, and allows the QinQ tunnel port to be
configured. The default is for the Managed Switch to function in Disable mode.
- Disable: The port operates in its normal VLAN mode. (This is the default.)
- MAN Port: Configures IEEE 802.1Q tunneling (QinQ) for an uplink port to
another device within the service provider network.
- Customer Port: Configures IEEE 802.1Q tunneling (QinQ) for a client access
port to segregate and preserve customer VLAN IDs for traffic crossing the
service provider network.
