It recommends using PLANET SFPs on the Managed Switch. If you insert a SFP transceiver that is
not supported, the Managed Switch will not recognize it.
Before connect the other Managed Switches, workstation or Media Converter.
1. Make sure both side of the SFP transceiver are with the same media type, for example: 1000Base-SX to 1000Base-SX,
1000Bas-LX to 1000Base-LX.
2. Check the fiber-optic cable type match the SFP transceiver model.
¾ To connect to 1000Base-SX SFP transceiver, use the Multi-mode fiber cable- with one side must be male duplex LC
connector type.
¾ To connect to 1000Base-LX SFP transceiver, use the Single-mode fiber cable-with one side must be male duplex LC
connector type.
Connect the fiber cable
1. Attach the duplex LC connector on the network cable into the SFP transceiver.
2. Connect the other end of the cable to a device – switches with SFP installed, fiber NIC on a workstation or a Media
Converter..
3. Check the LNK/ACT LED of the SFP slot on the front of the Managed Switch. Ensure that the SFP transceiver is operating
correctly.
4. Check the Link mode of the SFP port if the link failed. Co works with some fiber-NICs or Media Converters, set the Link
mode to “1000 Force” is needed.
Remove the transceiver module
1. Make sure there is no network activity by consult or check with the network administrator. Or through the management
interface of the switch/converter (if available) to disable the port in advance.
2. Remove the Fiber Optic Cable gently.
3. Turn the handle of the MGB module to horizontal.
4. Pull out the module gently through the handle.

2.3 Stack Installation
SGSW-24040 / SGSW-24040R
The SGSW-24040 series Managed Switch provides a switch stacking function to manage up to 16 switches using a single IP
address. And up to 384 Gigabit Ethernet ports can be managed by a stacking group and you can add ports and functionality as
needed. You can add SGSW-24040 series switches as needed to support more network clients, knowing that your switching
fabric will scale to meet increasing traffic demands.
Two types of stack topologies are supported by the SGSW-24040 series:
Chain topology (same as a disconnected ring)
Ring topology
Please find the following picture for sample connection.

SGSW-24040 / SGSW-24040R
2.3.1 Connecting Stacking cable
Before attempting to connect stacking ports, verify that you have the required stack cables. The following cables are used to
connect stacked switches:
• CB-STX50: 50cm, Short stack cable –used to connect adjacent SGSW switches.
• CB-STX200: 200cm, Long / Redundant stack cable – used to connect the top and bottom SGSW switches of a stack.
There are two high-performance HDMI-like Stack ports on the rear panel for proprietary management stack. Only attached
PLANET CB-STX50 and CB-STX200 cross-overed HDMI cable can be used.
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.
Figure 2-18 Stacking connection
STEP-3: If you wish to implement stack redundancy, use the long stack cable –CB-STX200 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.
The stack port is for management and data packets to be transmitted between other SGSW stackable
switches, the stack ports can’t be configured with Layer 2 features via management interface.
STEP-4: Power up the stack switches.
2.3.2 Management Stacking
The stack operation of the SGSW Managed Switch supports Plug and Play Stacking connection and auto stack configuration.
33
User’s Manual of WGSW-24040 / WGSW-24040R
SGSW-24040 / SGSW-24040R
STEP-5: Once the stack start operation, the Stack master be automatically elected without any configure. The Stack master is
indicated by a lit green “Master” LED on the front panel. As the Figure 2-19 appears.
Master LED
Figure 2-19 Stack Master with “Master” LED lit
Stack ID
STEP-6: When a SGSW Switch is added to the stack, a Switch ID is automatically assigned to the SGSW 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 SGSW Switch to
start the switch management. Or you can use the PLANET Smart Discovery Utility to displayt the IP address of the
stack and Web login the stack with this IP address. The default IP address of the SGSW 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.
2.
It’s allow to build a stack of up to 16 PLANET SGSW Switches. If there is the space limitation or power issue and you wish to
stack all the switches in different racks, use long stack cables “CB-STX200” to connect two stacks.

3.2 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
• Most visually appealing
• Communicates with switch functions at
the MIB level
• Based on open standards
• 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)
Table 3-1 Management Methods Comparison
3.3 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.
37
User’s Manual of WGSW-24040 / WGSW-24040R
SGSW-24040 / SGSW-24040R
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
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.

3.4 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.
Figure 3-3 Web management
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 6.0 or later, Safari or Mozilla Firefox 1.5 or later.
Figure 3-4 Web main screen of Managed Switch
39
User’s Manual of WGSW-24040 / WGSW-24040R
SGSW-24040 / SGSW-24040R
3.5 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.
Figure 3-4 SNMP management
3.6 Protocols
The Managed Switch supports the following protocols:
Virtual terminal protocols, such as Telnet
Simple Network Management Protocol (SNMP)
3.6.1 Virtual Terminal Protocols
A virtual terminal protocol is a software program, such as Telne t, that allows you to establish a management session from a
Macintosh, a PC, or a UNIX workstation. Because Telnet runs over TCP/IP, you must have at least one IP address configured on
the Managed Switch before you can establish access to it with a virtual terminal protocol.
Terminal emulation differs from a virtual terminal protocol in that you must connect a terminal directly
to the console (serial) port.
To access the Managed Switch through a Telnet session:
1. Be Sure of the Managed Switch is configured with an IP address and the Managed Switch is reachable from a PC.
40
User’s Manual of WGSW-24040 / WGSW-24040R
SGSW-24040 / SGSW-24040R
2. Start the Telnet program on a PC and connect to the Managed Switch.
The management interface is exactly the same with RS-232 console management.
3.6.2 SNMP Protocol
Simple Network Management Protocol (SNMP) is the standard management protocol for multi-vendor IP networks. SNMP
supports transaction-based queries that allow the protocol to format messages and to transmit information between reporting
devices and data-collection programs. SNMP runs on top of the User Datagram Protocol (UDP), offering a connectionless-mode
service.
3.6.3 Management Architecture
All of the management application modules use the same Messaging Application Programming Interface (MAPI). By unifying
management methods with a single MAPI, configuration parameters set using one method (console port, for example) are
immediately displayable by the other management methods (for example, SNMP agent of Web browser).
The management architecture of the switch adheres to the IEEE open standard. This compliance assures customers that the
Managed Switch is compatible with, and will interoperate with other solutions that adhere to the same open standard.

4. 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 6.0. 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, IE6.0 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 WGSW / SGSW 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.

4.3 Simple Network Management Protocol
4.3.1 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.
。 Trap -- 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

4.4.4 Port Mirroring Configuration
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.

The traffic to be copied to the mirror port is selected as follows:
• All frames received on a given port (also known as ingress or source mirroring).
• All frames transmitted on a given port (also known as egress or destination mirroring).

4.5 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 trounk 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.
Figure 4-5-1 Link Aggregation
85
User’s Manual of WGSW-24040 / WGSW-24040R
SGSW-24040 / SGSW-24040R
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
• Destination MAC
• Source and destination IPv4 address.
• Source and destination TCP/UDP ports for IPv4 packets
• IPv6 Flow Label
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 aggregation s 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.

4.6 VLAN
4.6.1 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
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.
This section has the following items:
IEEE 802.1Q VLAN

4.6.2 IEEE 802.1Q VLAN
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 4k 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
1. The Managed Switch allows 4k user-manageable VLANs.
2. One other VLAN (VLAN ID 4093) is reserved for switch clustering.
■ 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).
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
94
User’s Manual of WGSW-24040 / WGSW-24040R
SGSW-24040 / SGSW-24040R
ports and work normally.
Any port can be configured as either tagging or untagging. The untagging feature of IEEE 802.1Q VLAN allow 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.

recalculated.

■ 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
96
User’s Manual of WGSW-24040 / WGSW-24040R
SGSW-24040 / SGSW-24040R
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. However, you should use IEEE 802.3 tagged VLANs with GVRP whenever possible to fully automate VLAN
registration.

4.6.4 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:
Frame Leave
Leave port is tagged Frame remains tagged Tag is inserted
Leave port is untagged Tag is removed Frame remain 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 (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.
