1.2 Product Description
High-Performance / Cost-effective / Telecom class Gigabit solution for Enterprise backbone and Data
Center Networking
The PLANET 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 Gigabit Ethernet ports with 4 shared Gigabit SFP slots. It boasts 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 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 WGSW-24040 provides 802.1Q Tagged
VLAN, Q-in-Q VLAN trunning and private VLAN, the VLAN groups allowed on the WGSW-24040 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 eight groups of maximum to 8-ports for trunking, and it supports fail-over as well.
Excellent Traffic Control
PLANET WGSW-24040 is loaded 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.

SGSW-24040 / SGSW-24040R
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 10/50/70/120 kilometers (Single-Mode fiber or
WDM fiber). They are well suited for using within the enterprise data centers and distributions.
Reliability Stacking Management
The SGSW 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 SGSW Series Managed
Switch, but without the expensive up-front cost.
AC / DC Power Redundant to ensure continuous operation
The R series Managed Switch equip with one 100~240V AC power supply unit and one DC -48V power supply unit on its
standard package, it provides redundant power supply installation. A redundant power system is also provided to enhance the
reliability with either 100~240V AC power supply unit or DC -48V power supply unit. The continuous power systems are
specifically designed to handle the demands of high tech facilities requiring the highest power integrity available.
Advanced Features and Centralized Power Management for Enterprise and Campus PoE Networking (PoE Model)
The PLANET SGSW-24040P series PoE Switch 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.

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 2-26 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.
41
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.
Stack ID
Master LED
Figure 2-27 Stack Master with “Master” LED lit
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.

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.

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.

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.

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 Telnet, 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.
48
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

4.5 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
88
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
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.

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 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).
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.

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.

■ 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
99
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.

Understand nomenclature of the Switch
■ IEEE 802.1Q Tagged and Untagged
Every port on an 802.1Q compliant switch can be configured as tagged or untagged.
• Tagged:
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.
• Untagged:
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.
102
User’s Manual of WGSW-24040 / WGSW-24040R
SGSW-24040 / SGSW-24040R
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.

4.6.6 Private VLAN Configuration
Overview
When a VLAN is configured to be a private VLAN, communication between ports within that VLAN can be prevented. Two
application examples are provided in this section:
• Customers connected to an ISP can be members of the same VLAN, but they are not allowed to communicate with each
other within that VLAN.
• Servers in a farm of web servers in a Demilitarized Zone (DMZ) are allowed to communicate with the outside world and
with database servers on the inside segment, but are not allowed to communicate with each other
For private VLANs to be applied, the switch must first be configured for standard VLAN operation When this is in place, one or
more of the configured VLANs can be configured as private VLANs. Ports in a private VLAN fall into one of these two groups:
„
Promiscuous ports
— Ports from which traffic can be forwarded to all ports in the private VLAN
— Ports which can receive traffic from all ports in the private VLAN
„
Isolated ports
— Ports from which traffic can only be forwarded to promiscous ports in the private VLAN
— Ports which can receive traffic from only promiscuous ports in the private VLAN
The configuration of promiscuous and isolated ports applies to all private VLANs. When traffic comes in on a promiscuous port
in a private VLAN, the VLAN mask from the VLAN table is applied. When traffic comes in on an isolated port, the private VLAN
mask is applied in addition to the VLAN mask from the VLAN table. This reduces the ports to which forwarding can be done to
just the promiscuous ports within the private VLAN.

4.7 Rapid Spanning Tree Protocol
4.7.1 Theory
The Spanning Tree protocol can be used to detect and disable network loops, and to provide backup links between switches,
bridges or routers. This allows the switch to interact with other bridging devices in your network to ensure that only one route
exists between any two stations on the network, and provide backup links which automatically take over when a primary link
goes down. The spanning tree algorithms supported by this switch include these versions:
„
STP – Spanning Tree Protocol (IEEE 802.1D)
„
RSTP – Rapid Spanning Tree Protocol (IEEE 802.1w)
The IEEE 802.1D Spanning Tree Protocol and IEEE 802.1W Rapid Spanning Tree Protocol allow for the blocking of links
between switches that form loops within the network. When multiple links between switches are detected, a primary link is
established. Duplicated links are blocked from use and become standby links. The protocol allows for the duplicate links to be
used in the event of a failure of the primary link. Once the Spanning Tree Protocol is configured and enabled, primary links are
established and duplicated links are blocked automatically. The reactivation of the blocked links (at the time of a primary link
failure) is also accomplished automatically without operator intervention.
This automatic network reconfiguration provides maximum uptime to network users. However, the concepts of the Spanning
Tree Algorithm and protocol are a complicated and complex subject and must be fully researched and understood. It is possible
to cause serious degradation of the performance of the network if the Spanning Tree is incorrectly configured. Please read the
following before making any changes from the default values.
The Switch STP performs the following functions:
„
Creates a single spanning tree from any combination of switching or bridging elements.
„
Creates multiple spanning trees – from any combination of ports contained within a single switch, in user specified
groups.
„
Automatically reconfigures the spanning tree to compensate for the failure, addition, or removal of any element in
the tree.
„
Reconfigures the spanning tree without operator intervention.
Bridge Protocol Data Units
For STP to arrive at a stable network topology, the following information is used:
„
The unique switch identifier
„
The path cost to the root associated with each switch port
„
The por tidentifier
STP communicates between switches on the network using Bridge Protocol Data Units (BPDUs). Each BPDU contains the
following information:
„
The unique identifier of the switch that the transmitting switch currently believes is the root switch
„
The path cost to the root from the transmitting port
„
The port identifier of the transmitting port
109
User’s Manual of WGSW-24040 / WGSW-24040R
SGSW-24040 / SGSW-24040R
The switch sends BPDUs to communicate and construct the spanning-tree topology. All switches connected to the LAN on
which the packet is transmitted will receive the BPDU. BPDUs are not directly forwarded by the switch, but the receiving switch
uses the information in the frame to calculate a BPDU, and, if the topology changes, initiates a BPDU transmission.
The communication between switches via BPDUs results in the following:
„
One switch is elected as the root switch
„
The shortest distance to the root switch is calculated for each switch
„
A designated switch is selected. This is the switch closest to the root switch through which packets will be forwarded
to the root.
„
A port for each switch is selected. This is the port providing the best path from the switch to the root switch.
„
Ports included in the STP are selected.
Creating a Stable STP Topology
It is to make the root port a fastest link. If all switches have STP enabled with default settings, the switch with the lowest MAC
address in the network will become the root switch. By increasing the priority (lowering the priority number) of the best switch,
STP can be forced to select the best switch as the root switch.
When STP is enabled using the default parameters, the path between source and destination stations in a switched network
might not be ideal. For instance, connecting higher-speed links to a port that has a higher number than the current root port can
cause a root-port change.
STP Port States
The BPDUs take some time to pass through a network. This propagation delay can result in topology changes where a port that
transitioned directly from a Blocking state to a Forwarding state could create temporary data loops. Ports must wait for new
network topology information to propagate throughout the network before starting to forward packets. They must also wait for
the packet lifetime to expire for BPDU packets that were forwarded based on the old topology. The forward delay timer is used to
allow the network topology to stabilize after a topology change. In addition, STP specifies a series of states a port must
transition through to further ensure that a stable network topology is created after a topology change.
Each port on a switch using STP exists is in one of the following five states:
„
Blocking – the port is blocked from forwarding or receiving packets
„
Listening – the port is waiting to receive BPDU packets that may tell the port to go back to the blocking state
„
Learning – the port is adding addresses to its forwarding database, but not yet forwarding packets
„
Forwarding – the port is forwarding packets
„
Disabled – the port only responds to network management messages and must return to the blocking state first
A port transitions from one state to another as follows:
„
From initialization (switch boot) to blocking
„
From blocking to listening or to disabled
„
From listening to learning or to disabled
„
From learning to forwarding or to disabled
„
From forwarding to disabled
„
From disabled to blocking

Figure 4-7-1 STP Port State Transitions
You can modify each port state by using management software. When you enable STP, every port on every switch in the
network goes through the blocking state and then transitions through the states of listening and learning at power up. If properly
configured, each port stabilizes to the forwarding or blocking state. No packets (except BPDUs) are forwarded from, or received
by, STP enabled ports until the forwarding state is enabled for that port.
2. STP Parameters
STP Operation Levels
The Switch allows for two levels of operation: the switch level and the port level. The switch level forms a spanning tree
consisting of links between one or more switches. The port level constructs a spanning tree consisting of groups of one or more
ports. The STP operates in much the same way for both levels.
On the switch level, STP calculates the Bridge Identifier for each switch and then sets the Root
Bridge and the Designated Bridges.
On the port level, STP sets the Root Port and the Designated Ports.
The following are the user-configurable STP parameters for the switch level:

User-Changeable STA Parameters
The Switch’s factory default setting should cover the majority of installations. However, it is advisable to keep the default settings
as set at the factory; unless, it is absolutely necessary. The user changeable parameters in the Switch are as follows:
Priority – A Priority for the switch can be set from 0 to 65535. 0 is equal to the highest Priority.
Hello Time – The Hello Time can be from 1 to 10 seconds. This is the interval between two transmissions of BPDU packets sent
by the Root Bridge to tell all other Switches that it is indeed the Root Bridge. If you set a Hello Time for your Switch, and it is not
112
User’s Manual of WGSW-24040 / WGSW-24040R
SGSW-24040 / SGSW-24040R
the Root Bridge, the set Hello Time will be used if and when your Switch becomes the Root Bridge.
The Hello Time cannot be longer than the Max. Age. Otherwise, a configuration error will
occur.
Max. Age – The Max Age can be from 6 to 40 seconds. At the end of the Max Age, if a BPDU has still not been received from
the Root Bridge, your Switch will start sending its own BPDU to all other Switches for permission to become the Root Bridge. If it
turns out that your Switch has the lowest Bridge Identifier, it will become the Root Bridge.
Forward Delay Timer – The Forward Delay can be from 4 to 30 seconds. This is the time any port on the
Switch spends in the listening state while moving from the blocking state to the forwarding state.
Observe the following formulas when setting the above parameters:
Max. Age _ 2 x (Forward Delay - 1 second)
Max. Age _ 2 x (Hello Time + 1 second)
Port Priority – A Port Priority can be from 0 to 240. The lower the number, the greater the probability the port will be chosen as
the Root Port.
Port Cost – A Port Cost can be set from 0 to 200000000. The lower the number, the greater the probability the port will be
chosen to forward packets.
3. Illustration of STP
A simple illustration of three switches connected in a loop is depicted in the below diagram. In this example, you can anticipate
some major network problems if the STP assistance is not applied.
If switch A broadcasts a packet to switch B, switch B will broadcast it to switch C, and switch C will broadcast it to back to switch
A and so on. The broadcast packet will be passed indefinitely in a loop, potentially causing a network failure. In this example,
STP breaks the loop by blocking the connection between switch B and C. The decision to block a particular connection is based
on the STP calculation of the most current Bridge and Port settings.
Now, if switch A broadcasts a packet to switch C, then switch C will drop the packet at port 2 and the broadcast will end there.
Setting-up STP using values other than the defaults, can be complex. Therefore, you are advised to keep the default factory
settings and STP will automatically assign root bridges/ports and block loop connections. Influencing STP to choose a particular
switch as the root bridge using the Priority setting, or influencing STP to choose a particular port to block using the Port Priority
and Port Cost settings is, however, relatively straight forward.

The switch with the lowest Bridge ID (switch C) was elected the root bridge, and the ports were selected to give a high port cost
between switches B and C. The two (optional) Gigabit ports (default port cost = 4) on switch A are connected to one (optional)
Gigabit port on both switch B and C. The redundant link between switch B and C is deliberately chosen as a 100 Mbps Fast
Ethernet link (default port cost = 19). Gigabit ports could be used, but the port cost should be increased from the default to
ensure that the link between switch B and switch C is the blocked link.

4.8 Quality of Service
4.8.1 Understand QOS
Quality of Service (QoS) is an advanced traffic prioritization feature that allows you to establish control over network traffic. QoS
enables you to assign various grades of network service to different types of traffic, such as multi-media, video, protocol-specific,
time critical, and file-backup traffic.
QoS reduces bandwidth limitations, delay, loss, and jitter. It also provides increased reliability for delivery of your data and
allows you to prioritize certain applications across your network. You can define exactly how you want the switch to treat
selected applications and types of traffic.
You can use QoS on your system to:
• Control a wide variety of network traffic by:
• Classifying traffic based on packet attributes.
• Assigning priorities to traffic (for example, to set higher priorities to time-critical or business-critical applications).
• Applying security policy through traffic filtering.
• Provide predictable throughput for multimedia applications such as video conferencing or voice over IP by minimizing
delay and jitter.
• Improve performance for specific types of traffic and preserve performance as the amount of traffic grows.
• Reduce the need to constantly add bandwidth to the network.
• Manage network congestion.
QoS Terminology
• Classifier-classifies the traffic on the network. Traffic classifications are determined by protocol, application, source,
destination, and so on. You can create and modify classifications. The Switch then groups classified traffic in order to
schedule them with the appropriate service level.
• DiffServ Code Point (DSCP) - is the traffic prioritization bits within an IP header that are encoded by certain
applications and/or devices to indicate the level of service required by the packet across a network.
• Service Level-defines the priority that will be given to a set of classified traffic. You can create and modify service
levels.
• Policy-comprises a set of “rules” that are applied to a network so that a network meets the needs of the business. That
is, traffic can be prioritized across a network according to its importance to that particular business type.
• QoS Profile-consists of multiple sets of rules (classifier plus service level combinations). The QoS profile is assigned
to a port(s).
• Rules-comprises a service level and a classifier to define how theSwitch will treat certain types of traffic. Rules are
associated with a QoS Profile (see above).
To implement QoS on your network, you need to carry out the following actions:
1.
Define a service level to determine the priority that will be applied to traffic.
2.
Apply a classifier to determine how the incoming traffic will be classified and thus treated by the Switch.
122
User’s Manual of WGSW-24040 / WGSW-24040R
SGSW-24040 / SGSW-24040R
3.
Create a QoS profile which associates a service level and a classifier.
4.
Apply a QoS profile to a port(s).
4.8.2 QoS Control List Configuration

4.9 Multicast
4.9.1 IGMP Snooping
The Internet Group Management Protocol (IGMP) lets host and routers share information about multicast groups
memberships. IGMP snooping is a switch feature that monitors the exchange of IGMP messages and copies them to the CPU
for feature processing. The overall purpose of IGMP Snooping is to limit the forwarding of multicast frames to only ports that are
a member of the multicast group.
About the Internet Group Management Protocol (IGMP) Snooping
Computers and network devices that want to receive multicast transmissions need to inform nearby routers that they will
become members of a multicast group. The Internet Group Management Protocol (IGMP) is used to communicate this
information. IGMP is also used to periodically check the multicast group for members that are no longer active. In the case
where there is more than one multicast router on a sub network, one router is elected as the ‘queried’. This router then keeps
track of the membership of the multicast groups that have active members. The information received from IGMP is then used to
determine if multicast packets should be forwarded to a given sub network or not. The router can check, using IGMP, to see if
there is at least one member of a multicast group on a given subnet work. If there are no members on a sub network, packets
will not be forwarded to that sub network.

IGMP Versions 1 and 2
Multicast groups allow members to join or leave at any time. IGMP provides the method for members and multicast routers to
communicate when joining or leaving a multicast group.
IGMP version 1 is defined in RFC 1112. It has a fixed packet size and no optional data.
The format of an IGMP packet is shown below:

IGMP packets enable multicast routers to keep track of the membership of multicast groups, on their respective sub networks.
The following outlines what is communicated between a multicast router and a multicast group member using IGMP.
A host sends an IGMP “report” to join a group
A host will never send a report when it wants to leave a group (for version 1).
A host will send a “leave” report when it wants to leave a group (for version 2).
Multicast routers send IGMP queries (to the all-hosts group address: 224.0.0.1) periodically to see whether any group members
exist on their sub networks. If there is no response from a particular group, the router assumes that there are no group members
on the network.
The Time-to-Live (TTL) field of query messages is set to 1 so that the queries will not be forwarded to other sub networks.
IGMP version 2 introduces some enhancements such as a method to elect a multicast queried for each LAN, an explicit leave

IGMP Querier –
A router, or multicast-enabled switch, can periodically ask their hosts if they want to receive multicast traffic. If there is more
than one router/switch on the LAN performing IP multicasting, one of these devices is elected “querier” and assumes the
role of querying the LAN for group members. It then propagates the service requests on to any upstream multicast
switch/router to ensure that it will continue to receive the multicast service.
Multicast routers use this information, along with a multicast routing protocol such as
DVMRP or PIM, to support IP multicasting across the Internet.

4.10 IEEE 802.1X Network Access Control
Overview of 802.1X (Port-Based) Authentication
In the 802.1X-world, the user is called the supplicant, the switch is the authenticator, and the RADIUS server is the
authentication server. The switch acts as the man-in-the-middle, forwarding requests and responses between the supplicant
and the authentication server. Frames sent between the supplicant and the switch are special 802.1X frames, known as EAPOL
(EAP Over LANs) frames. EAPOL frames encapsulate EAP PDUs (RFC3748). Frames sent between the switch and the
RADIUS server are RADIUS packets. RADIUS packets also encapsulate EAP PDUs together with other attributes like the
switch's IP address, name, and the supplicant's port number on the switch. EAP is very flexible, in that it allows for different
authentication methods, like MD5-Challenge, PEAP, and TLS. The important thing is that the authenticator (the switch) doesn't
need to know which authentication method the supplicant and the authentication server are using, or how many information
exchange frames are needed for a particular method. The switch simply encapsulates the EAP part of the frame into the
relevant type (EAPOL or RADIUS) and forwards it.
When authentication is complete, the RADIUS server sends a special packet containing a success or failure indication. Besides
forwarding this decision to the supplicant, the switch uses it to open up or block traffic on the switch port connected to the
supplicant.
Overview of MAC-Based Authentication
Unlike 802.1X, MAC-based authentication is not a standard, but merely a best-practices method adopted by the industry. In
MAC-based authentication, users are called clients, and the switch acts as the supplicant on behalf of clients. The initial frame
(any kind of frame) sent by a client is snooped by the switch, which in turn uses the client's MAC address as both username and
password in the subsequent EAP exchange with the RADIUS server. The 6-byte MAC address is converted to a string on the
following form "xx-xx-xx-xx-xx-xx", that is, a dash (-) is used as separator between the lower-cased hexadecimal digits. The
switch only supports the MD5-Challenge authentication method, so the RADIUS server must be configured accordingly.
When authentication is complete, the RADIUS server sends a success or failure indication, which in turn causes the switch to
open up or block traffic for that particular client, using static entries into the MAC Table. Only then will frames from the client be
forwarded on the switch. There are no EAPOL frames involved in this authentication, and therefore, MAC-based Authentication
has nothing to do with the 802.1X standard.
The advantage of MAC-based authentication over 802.1X is that several clients can be connected to the same port (e.g. through
a 3rd party switch or a hub) and still require individual authentication, and that the clients don't need special supplicant software
to authenticate. The disadvantage is that MAC addresses can be spoofed by malicious users, equipment whose MAC address
is a valid RADIUS user can be used by anyone, and only the MD5-Challenge method is supported.
The 802.1X and MAC-Based Authentication configuration consists of two sections, a system- and a port-wide.

4.10.1 Understanding IEEE 802.1X Port-Based Authentication
The IEEE 802.1X standard defines a client-server-based access control and authentication protocol that restricts unauthorized
clients from connecting to a LAN through publicly accessible ports. The authentication server authenticates each client
connected to a switch port before making available any services offered by the switch or the LAN.
Until the client is authenticated, 802.1X access control allows only Extensible Authentication Protocol over LAN (EAPOL)
traffic through the port to which the client is connected. After authentication is successful, normal traffic can pass through the
port.
This section includes this conceptual information:
• Device Roles
• Authentication Initiation and Message Exchange
• Ports in Authorized and Unauthorized States
Device Roles
„
With 802.1X port-based authentication, the devices in the network have specific roles as shown below.
Figure 4-10-1
z
Client—the device (workstation) that requests access to the LAN and switch services and responds to requests from
the switch. The workstation must be running 802.1X-compliant client software such as that offered in the Microsoft
Windows XP operating system. (The client is the supplicant in the IEEE 802.1X specification.)
z
Authentication server—performs the actual authentication of the client. The authentication server validates the
identity of the client and notifies the switch whether or not the client is authorized to access the LAN and switch services.
Because the switch acts as the proxy, the authentication service is transparent to the client. In this release, the Remote
Authentication Dial-In User Service (RADIUS) security system with Extensible Authentication Protocol (EAP)
extensions is the only supported authentication server; it is available in Cisco Secure Access Control Server version 3.0.
RADIUS operates in a client/server model in which secure authentication information is exchanged between the
RADIUS server and one or more RADIUS clients.
145
User’s Manual of WGSW-24040 / WGSW-24040R
SGSW-24040 / SGSW-24040R
z
Switch (802.1X device)—controls the physical access to the network based on the authentication status of the client.
The switch acts as an intermediary (proxy) between the client and the authentication server, requesting identity
information from the client, verifying that information with the authentication server, and relaying a response to the client.
The switch includes the RADIUS client, which is responsible for encapsulating and decapsulating the Extensible
Authentication Protocol (EAP) frames and interacting with the authentication server. When the switch receives EAPOL
frames and relays them to the authentication server, the Ethernet header is stripped and the remaining EAP frame is
re-encapsulated in the RADIUS format. The EAP frames are not modified or examined during encapsulation, and the
authentication server must support EAP within the native frame format. When the switch receives frames from the
authentication server, the server's frame header is removed, leaving the EAP frame, which is then encapsulated for
Ethernet and sent to the client.
„
Authentication Initiation and Message Exchange
The switch or the client can initiate authentication. If you enable authentication on a port by using the dot1x port-control auto
interface configuration command, the switch must initiate authentication when it determines that the port link state transitions
from down to up. It then sends an EAP-request/identity frame to the client to request its identity (typically, the switch sends an
initial identity/request frame followed by one or more requests for authentication information). Upon receipt of the frame, the
client responds with an EAP-response/identity frame.
However, if during bootup, the client does not receive an EAP-request/identity frame from the switch, the client can initiate
authentication by sending an EAPOL-start frame, which prompts the switch to request the client's identity
If 802.1X is not enabled or supported on the network access device, any EAPOL frames from the
client are dropped. If the client does not receive an EAP-request/identity frame after three attempts
to start authentication, the client transmits frames as if the port is in the authorized state. A port in
the authorized state effectively means that the client has been successfully authenticated.
When the client supplies its identity, the switch begins its role as the intermediary, passing EAP frames between the client and
the authentication server until authentication succeeds or fails. If the authentication succeeds, the switch port becomes
authorized.
The specific exchange of EAP frames depends on the authentication method being used. “Figure 4-10-1” shows a message
exchange initiated by the client using the One-Time-Password (OTP) authentication method with a RADIUS server.

„
Ports in Authorized and Unauthorized States
The switch port state determines whether or not the client is granted access to the network. The port starts in the unauthorized
state. While in this state, the port disallows all ingress and egress traffic except for 802.1X protocol packets. When a client is
successfully authenticated, the port transitions to the authorized state, allowing all traffic for the client to flow normally.
If a client that does not support 802.1X is connected to an unauthorized 802.1X port, the switch requests the client's identity. In
this situation, the client does not respond to the request, the port remains in the unauthorized state, and the client is not granted
access to the network.
In contrast, when an 802.1X-enabled client connects to a port that is not running the 802.1X protocol, the client initiates the
authentication process by sending the EAPOL-start frame. When no response is received, the client sends the request for a
fixed number of times. Because no response is received, the client begins sending frames as if the port is in the authorized state
If the client is successfully authenticated (receives an Accept frame from the authentication server), the port state changes to
authorized, and all frames from the authenticated client are allowed through the port. If the authentication fails, the port remains
in the unauthorized state, but authentication can be retried. If the authentication server cannot be reached, the switch can
retransmit the request. If no response is received from the server after the specified number of attempts, authentication fails,
and network access is not granted.
When a client logs off, it sends an EAPOL-logoff message, causing the switch port to transition to the unauthorized state.
If the link state of a port transitions from up to down, or if an EAPOL-logoff frame is received, the port returns to the unauthorized
state.

4.10.2 802.1X System Configuration
This page allows you to configure the IEEE 802.1X and MAC-based authentication system and port settings.
The IEEE 802.1X standard defines a port-based access control procedure that prevents unauthorized access to a network by
requiring users to first submit credentials for authentication. A central server, the RADIUS server, determines whether the user is
allowed access to the network.
MAC-based authentication allows for authentication of more than one user on the same port, and doesn't require the user to
have special 802.1X software installed on his system. The Managed Switch uses the user's MAC address to authenticate
against the RADIUS server. Intruders can create counterfeit MAC addresses, which makes MAC-based authentication less
secure than 802.1X authentication.
The 802.1X System Configuration screen in Figure 4-10-3 appears.

• RADIUS IP

the RADIUS IP changes while the protocol is globally enabled, then all
ports/clients will get reinitialized.
• RADIUS Secret
The secret - up to 29 characters long - shared between the RADIUS Server and
the switchstack.

• Reauthentication
Enabled
If checked, clients are reauthenticated after the interval specified by the
Reauthentication Period. Reauthentication for 802.1X-enabled ports can be used
to detect if a new device is plugged into a switch port.
For MAC-based ports, reauthentication is only useful if the RADIUS server
configuration has changed. It does not involve communication between the
switch and the client, and therefore doesn't imply that a client is still present on a
port (see Age Period below).
• Reauthentication
Period
Determines the period, in seconds, after which a connected client must be
reauthenticated. This is only active if the Reauthentication Enabled checkbox is
checked. Valid values are in the range 1 to 3600 seconds.
• EAP Timeout
Determines the time the switch shall wait for the supplicant response before
retransmitting a packet. Valid values are in the range 1 to 255 seconds. This has
no effect for MAC-based ports.
• Age Period
This setting applies to ports running MAC-based authentication, only.
Suppose a client is connected to a 3rd party switch or hub, which in turn is
connected to a port on this switch that runs MAC-based authentication, and
suppose the client gets successfully authenticated. Now assume that the client
powers down his PC. What should make the switch forget about the
authenticated client? Reauthentication will not solve this problem, since this
doesn't require the client to be present, as discussed under Reauthentication
Enabled above. The solution is aging of authenticated clients. The Age Period,
which can be set to a number between 10 and 1000000 seconds, works like this:
A timer is started when the client gets authenticated. After half the age period, the
switch starts looking for frames sent by the client. If another half age period
elapses and no frames are seen, the client is considered removed from the
system, and it will have to authenticate again the next time a frame is seen from
it. If, on the other hand, the client transmits a frame before the second half of the
age period expires, the switch will consider the client alive, and leave it
authenticated, and restart the age timer.
• Hold Time
This setting applies to ports running MAC-based authentication, only.
If the RADIUS server denies a client access, or a RADIUS server request times
out (after 40 seconds with two retries), the client is put on hold in the
Unauthorized state. In this state, frames from the client will not cause the switch
to attempt to reauthenticate the client. The Hold Time, which can be set to a
number between 10 and 1000000 seconds, determines the time after an EAP
Failure indication or RADIUS timeout that a client is not allowed access.

The current state of the port. It can undertake one of the following values:
• 802.1X Disabled: 802.1X and MAC-based authentication is globally
disabled.
• Link Down: 802.1X or MAC-based authentication is enabled, but there is
no link on the port.
• Authorized: The port is authorized. This is the case when 802.1X
authentication is enabled, the port has link, and the Admin State is "Auto"
and the supplicant is authenticated or the Admin State is "Authorized".
• Unauthorized: The port is unauthorized. This is the case when 802.1X
authentication is enabled, the port has link, and the Admin State is "Auto",
but the supplicant is not (yet) authenticated or the Admin State is
"Unauthorized".
• X Auth/Y Unauth: X clients are currently authorized and Y are
unauthorized. This state is shown when 802.1X and MAC-based
authentication is globally enabled and the Admin State is set to
"MAC-Based".
• Max Clients
This setting applies to ports running MAC-based authentication, only.
The maximum number of clients allowed on a given port can be configured
through the list-box and edit-control for this setting. Choosing the value "All" from
the list-box allows the port to consume up to 104 client state-machines. Choosing
151
User’s Manual of WGSW-24040 / WGSW-24040R
SGSW-24040 / SGSW-24040R
the value "Specific" from the list-box opens up for entering a specific number of
maximum clients on the port (1 to 104).
The stackswitch is "born" with a pool of state-machines, from which all ports draw
whenever a new client is seen on the port. When a given port's maximum is
reached (both authorized and unauthorized clients count), further new clients are
disallowed access. Since all ports draw from the same pool, it may happen that a
configured maximum cannot be granted, if the remaining ports have already used
all available state-machines.
• Restart
Two buttons are available for each row. The buttons are only enabled when
authentication is globally enabled and the port's Admin State is "Auto" or
"MAC-Based".
Clicking these buttons will not cause settings changed on the page to take effect.
• Reauthenticate: Schedules a reauthentication to whenever the
quiet-period of the port runs out (port-based authentication). For
MAC-based authentication, reauthentication will be attempted immediately.
The button only has effect for successfully authenticated ports/clients and will not
cause the port/client to get temporarily unauthorized.
• Reinitialize: Forces a reinitialization of the port/clients and thereby a
reauthentication immediately. The port/clients will transfer to the
unauthorized state while the reauthentication is ongoing.

4.11 Access Control Lists
ACL is an acronym for Access Control List. It is the list table of ACEs, containing access control entries that specify individual
users or groups permitted or denied to specific traffic objects, such as a process or a program.
Each accessible traffic object contains an identifier to its ACL. The privileges determine whether there are specific traffic object
access rights.
ACL implementations can be quite complex, for example, when the ACEs are prioritized for the various situation. In networking,
the ACL refers to a list of service ports or network services that are available on a host or server, each with a list of hosts or
servers permitted or denied to use the service. ACL can generally be configured to control inbound traffic, and in this context,
they are similar to firewalls.
ACE is an acronym for Access Control Entry. It describes access permission associated with a particular ACE ID.
There are three ACE frame types (Ethernet Type, ARP, and IPv4) and two ACE actions (permit and deny). The ACE also
contains many detailed, different parameter options that are available for individual application.
4.11.1 Access Control List Configuration
This page shows the Access Control List (ACL), which is made up of the ACEs defined for this Managed Switch. Each row
describes the ACE that is defined.

4.12 Address Table
Switching of frames is based upon the DMAC address contained in the frame. The Managed Switch builds up a table that maps
MAC addresses to switch ports for knowing which ports the frames should go to ( based upon the DMAC address in the frame ).
This table contains both static and dynamic entries. The static entries are configured by the network administrator if the
administrator wants to do a fixed mapping between the DMAC address and switch ports.
The frames also contain a MAC address ( SMAC address ), which shows the MAC address of the equipment sending the frame.
The SMAC address is used by the switch to automatically update the MAC table with these dynamic MAC addresses. Dynamic
entries are removed from the MAC table if no frame with the corresponding SMAC address have been seen after a configurable
age time.

4.13 Port Security (To be Continued)
Port security is a feature that allows you to configure a switch port with one or more device MAC addresses that are authorized
to access the network through that port.
When port security is enabled on a port, the Managed Switch stops learning new MAC addresses on the specified port when it
has reached a configured maximum number. Only incoming traffic with source addresses already stored in the dynamic or static
address table will be authorized to access the network through that port. If a device with an unauthorized MAC address attempts
to use the switch port, the intrusion will be detected and the switch can automatically take action by disabling the port and
sending a trap message.
<source MAC address, VLAN> pair for frames received on the port.
Note that you can also manually add secure addresses to the port using the Static Address Table. The selected port will stop
learning. The MAC addresses already in the address table will be retained and will not age out. Any other device that attempts to
use the port will be prevented from accessing the switch.

4.14 LLDP
4.14.1 Link Layer Discovery Protocol
Link Layer Discovery Protocol (LLDP) is used to discover basic information about neighboring devices on the local broadcast
domain. LLDP is a Layer 2 protocol that uses periodic broadcasts to advertise information about the sending device. Advertised
information is represented in Type Length Value (TLV) format according to the IEEE 802.1ab standard, and can include details
such as device identification, capabilities and configuration settings. LLDP also defines how to store and maintain information
gathered about the neighboring network nodes it discovers.
Link Layer Discovery Protocol - Media Endpoint Discovery (LLDP-MED) is an extension of LLDP intended for managing
endpoint devices such as Voice over IP phones and network switches. The LLDP-MED TLVs advertise information such as
network policy, power, inventory, and device location details. LLDP and LLDP-MED information can be used by SNMP
applications to simplify troubleshooting, enhance network management, and maintain an accurate network topology.

LLDP Parameters
Object
Description
• Tx Interval
The switch is periodically transmitting LLDP frames to its neighbors for having the
network discovery information up-to-date. The interval between each LLDP
frame is determined by the Tx Interval value. Valid values are restricted to 5 32768 seconds.
Default: 30 seconds
192
User’s Manual of WGSW-24040 / WGSW-24040R
SGSW-24040 / SGSW-24040R
This attribute must comply with the following rule:
(Transmission Interval * Hold Time Multiplier) ≤65536, and Transmission Interval
>= (4 * Delay Interval)
• Tx Hold
Each LLDP frame contains information about how long the information in the
LLDP frame shall be considered valid. The LLDP information valid period is set to
Tx Hold multiplied by Tx Interval seconds. Valid values are restricted to 2 - 10
times.
TTL in seconds is based on the following rule:
(Transmission Interval * Holdtime Multiplier) ≤ 65536.
Therefore, the default TTL is 4*30 = 120 seconds.
• Tx Delay
If some configuration is changed (e.g. the IP address) a new LLDP frame is
transmitted, but the time between the LLDP frames will always be at least the

4.16 Stacking – SGSW-24040 / SGSW-24040R
Using Stacking, it is possible to connect a number of switches together in a stack, which behaves as a single switch as seen
from outside the stack.
Two types of stack topologies are supported:
„
Ring topology
„
Chain topology (same as a disconnected ring)
Multiple PLANET SGSW-24040 / SGSW-24040R devices may be connected together to constitute a ring or chain stack
topology using the STX / 5Gbps ports as interconnect links. Dedicated stacking features built into SGSW-24040 /
SGSW-24040R makes all devices in the stack operate together as a single, much larger switch. Among the stacking features
are:
„
Hardware controlled stack wide learning and continuous automatic MAC table synchronization
„
Shortest path forwarding, providing low latency and optimal use of stacking link bandwidth
„
QoS consistency across stack
„
Single point of management for simple stack administration
„
Low Cost and Flexible HDMI-like Stacking cables
„
Real Plug and Play connectivity
„
The following figure shows an example with five devices in a ring topology stack. Each device in the stack is, in a stack context,
called a unit. The ports connecting the units are called stack ports, and the ports connecting to external hosts and switches are
called front ports.

4.16.1.1 Switch IDs
The Switch ID (1-16) assigned to a SGSW Switch.
„
Assigning and Swapping Switch IDs
When a switch is added to the stack, a Switch ID is automatically assigned to the 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.
The Switch IDs of two switches can be swapped by simply interchanging the values in the Switch ID column.
Changing Switch IDs does not result in any interruption of the stack operation.
„
Removing a Switch From the Stack
When a switch is removed from the stack, the configuration for the switch is preserved, and the switch still appears on the
Stack Configuration page. If the configuration of the switch is not to be transferred to another switch, then the configuration
may be deleted by choosing Delete, followed by "Save".
„
Replacing a Switch
If a switch is to be replaced with another switch (for example, replacing failing hardware), the following procedure must be
used to assign the configuration of the failing switch to the new hardware:
1.
Remove the failing switch from the stack. For example, assume that the failing switch had Switch ID 3.
2.
Insert the new switch into the stack. The new switch is assigned an unused Switch ID.
3.
To remove the automatic switch ID assignment, choose "Delete", followed by "Save". The new switch is then
shown with Switch ID set to "-".
4.
To assign the configuration of Switch ID 3 to the new hardware, simply choose 3 in the Switch ID column and click
202
User’s Manual of WGSW-24040 / WGSW-24040R
SGSW-24040 / SGSW-24040R
"Save".
5.
„
The new hardware has now taken over the configuration of the failing hardware.
General Switch ID Assignment Rules
When assigning Switch IDs to the devices in the stack, you must note the following:
1.
Switches with assigned IDs can be changed to use any other switch ID (possibly by swapping Switch ID with
another active switch).
2.
When swapping two Switch IDs, the devices will retain their (own) configuration, except for the Switch ID.
3.
Switches without an assigned Switch ID can only be assigned to any unused ID.
4.
When assigning a Switch ID of an inactive switch to a new switch, the new switch will inherit the former's
configuration (see "Replacing a Switch" above).
5.
Deleting a switch will remove any configuration pertaining to it.
6.
Deleting an active switch will leave it with an unassigned Switch ID until rebooted or manually assigning a Switch
ID.
4.16.1.2 Master Election
Within a managed stack, one master switch (or just "master") must be elected. Any switch not being master is a slave switch (or
just "slave").
To elect a master, the following criteria are evaluated sequentially:
1. If any switch already claims to have been master for more than 30 seconds, then that switch will become
master.
2. If multiple switches claim to have been master for more than 30 seconds, then the switch which has been
master for the longest period of time will become master.
3. The switch with the smallest master priority.
4. The switch with the smallest MAC address.
The above algorithm ensures that once a master has been elected and has been master for more than 30 seconds, it will remain
master. However in some cases the user may want to enforce a new master election.
4.16.1.3 Stack Redundancy
In the unlikely event that a SGSW Switch fails in a stack, stack integrity is maintained if the redundant cable is connected to the
stack. The affected switch within the sack can be replaced or removed without disrupting normal operation. The broken link is
bypassed and data transmission continues uninterrupted. The single management IP address for the stack is also preserved for
uninterrupted management and monitoring.

Stacking function is convenient for administrator to manage multiple switches by single IP. Basically, you got to have min. 2 units.
The SGSW Switch supports auto stack configuration. Once the stack cable is connect to the stack port of each SGSW switch
and power on them, the stack is builded automatically and the Switch ID is automatically assigned to the switch. It is also easy
to add or delete stackable switch to the stack without service interruption. The key point of the Stack management are:
„
Identify the MASTER SWITCH
„
Assign / re-assing Switch ID for each management purpose
Step 1: linking the switches by CB-STX50 stack cable.
Step 2: Check the Master LED of each SGSW switch to find out the Master Switch that is elected automatically by the stack
operation.
Step 3: Use the Web browser such as IE 6.0 to login the Master Switch, the default IP address is 192.168.0.100. Or you can use
the PLANET Smart Discovery Utility to find out the IP address of the stack group.

the installation time.
4.17.2 Power Configuration
In a power over Ethernet system, operating power is applied from a power source (PSU-power supply unit) over the LAN
infrastructure to powered devices (PDs), which are connected to ports. Under some conditions, the total output power required
by PDs can exceed the maximum available power provided by the PSU. The system may a prior be planed with a PSU capable
of supplying less power than the total potential power consumption of all the PoE ports in the system. In order to maintain the
majority of ports active, power management is implemented.
The PSU input power consumption is monitored by measuring voltage and current .The input power consumption is equal to the
system’s aggregated power consumption .The power management concept allows all ports to be active and activates additional
ports, as long as the aggregated power of the system is lower than the power level at which additional PDs cannot be
connected .When this value is exceeded, ports will be deactivated, according to user-defined priorities. The power budget is
managed according to the following user-definable parameters: maximum available power, ports priority, maximum allowable
power per port.
Reserved Power determined by
There are five modes for configuring how the ports/PDs may reserve power and when to shut down ports.

Allocation mode
In this mode the user allocates the amount of power that each port may reserve. The allocated/reserved power for each
port/PD is specified in the Maximum Power fields. The ports are shut down when total reserved powered exceeds the
amount of power that the power supply can deliver.
In this mode the port power is not turned on if the PD requests more power the available.
„
Auto mode
The Power Management function will automatically select the mode of operation, according to the following sequence:
„
z
Port class, if available
z
Power allocation, if available
z
Port power consumption.
Consumption
In this mode the ports are shut down when the actual power consumption for all ports exceeds the amount of power that the
power supply can deliver or if the actual power consumption for a given port exceeds the reserved power for that port. The
ports are shut down according to the ports priority. If two ports have the same priority the port with the highest port number
is shut down.

Priority mode
In this mode the user assign the priority to the ports/PD. When the total PoE power consumption request is over the allowed

• Local Port
This is the logical port number for this row.
• PoE Enabled
The PoE Enabled represents whether the PoE is enable for the port.
• Priority
The Priority represents the ports priority. There are three levels of power priority
named Low, High and Critical.
The priority is used in the case where the remote devices requires uses more
power than power supply can deliver. In this case the port with the lowest priority
will be turn off starting from the port with the lowest port number.
• Maximum Power
The Maximum Power value contains a numerical value that indicates the
maximum power in watts that can be delived to a remote device.
• Power Allocation
It can limit the port PoE supply watts. Per port maximum value must less 15.4,
total ports values must less than the Power Reservation value.
Once power overload detected, the port will auto shut down and keep on
detection mode until PD’s power consumption lower than the power limit value.
Note. The system PoE mode have to set to Allocation mode then it effect.
For SGSW-24040P, the total PoE power reservation from Port-1~24 is up to 220W
For SGSW-24040P4, the total PoE power reservation from Port-1~24 is up to 380W
PD Classifications
A PD may be classified by the PSE based on the classification information provided by the PD. The intent of PD classification is
to provide information about the maximum power required by the PD during operation. Class 0 is the default for PDs. However,
to improve power management at the PSE, the PD may opt to provide a signature for Class 1 to 3.
The PD is classified based on power. The classification of the PD is the maximum power that the PD will draw across all input
voltages and operational modes.

5. COMMAND LINE INTERFACE
5.1 Accessing the CLI
When accessing the management interface for the switch over a direct connection to the server’s console port, or via a Telnet
connection, the switch can be managed by entering command keywords and parameters at the prompt. Using the switch's
command-line interface (CLI) is very similar to entering commands on a UNIX system.
This chapter describes how to use the Command Line Interface (CLI).
Logon to the Console
Once the terminal has connected to the device, power on the WGSW / SGSW Managed Switch, the terminal will display that it is
running testing procedures.
Then, the following message asks the login password. The factory default password as following and the login screen in Figure
5-1 appears.
Password: admin

For security reason, please change and memorize the new password after this first setup.
2.
Only accept command in lowercase letter under console interface.
Configure IP address
The WGSW / SGSW Managed Switch is shipped with default IP address as following.
IP Address : 192.168.0.100
Subnet Mask : 255.255.255.0
To check the current IP address or modify a new IP address for the Switch, please use the procedures as follow:
„
Show the current IP address
1.
On ”Switch/> ” prompt, enter “show ip”.
2.
The screen displays the current IP address, Subnet Mask and Gateway. As show in Figure 5-2.

On “Switch/> ” prompt, enter the following command and press <Enter>. As show in Figure 5-3.
Switch/> ip setup 192.168.1.100 255.255.255.0 192.168.1.1
The previous command would apply the follow settings for the Switch.
IP: 192.168.1.100
Subnet Mask: 255.255.255.0
Gateway: 192.168.1.1
Figure 5-3 Set IP address screen
4.
Repeat Step 1 to check if the IP address is changed.
If the IP is successfully configured, the Managed Switch will apply the new IP address setting immediately. You can access the
Web interface of WGSW / SGSW Managed Switch through the new IP address.
If you do not familiar with console command or the related parameter, enter “help” anytime in
console to get the help description.
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

such as TIP
5.2 Telnet login
The Managed Switch also supports telnet for remote management. The switch asks for user name and password for remote
login when using telnet, please use “admin” for password.

7. SWITCH OPERATION
7.1 Address Table
The Switch is implemented with an address table. This address table composed of many entries. Each entry is used to store the
address information of some node in network, including MAC address, port no, etc. This in-formation comes from the learning
process of Ethernet Switch.
7.2 Learning
When one packet comes in from any port, the Switch will record the source address, port no. And the other related information
in address table. This information will be used to decide either forwarding or filtering for future packets.
7.3 Forwarding & Filtering
When one packet comes from some port of the Ethernet Switching, it will also check the destination address besides the source
address learning. The Ethernet Switching will lookup the address-table for the destination address. If not found, this packet will
be forwarded to all the other ports except the port, which this packet comes in. And these ports will transmit this packet to the
network it connected. If found, and the destination address is located at different port from this packet comes in, the Ethernet
Switching will forward this packet to the port where this destination address is located according to the information from address
table. But, if the destination address is located at the same port with this packet comes in, then this packet will be filtered.
Thereby increasing the network throughput and availability
7.4 Store-and-Forward
Store-and-Forward is one type of packet-forwarding techniques.
A Store-and-Forward Ethernet Switching stores the incoming
frame in an internal buffer, do the complete error checking before transmission. Therefore, no error packets occurrence, it is the
best choice when a network needs efficiency and stability.
The Ethernet Switch scans the destination address from the packet-header, searches the routing table pro-vided for the
incoming port and forwards the packet, only if required. The fast forwarding makes the switch attractive for connecting servers
directly to the network, thereby increasing throughput and availability. How-ever, the switch is most commonly used to segment
existence hubs, which nearly always improves overall performance. An Ethernet Switching can be easily configured in any
Ethernet network environment to signifi-cantly boost bandwidth using conventional cabling and adapters.
Due to the learning function of the Ethernet switching, the source address and corresponding port number of each incoming and
outgoing packet are stored in a routing table. This information is subsequently used to filter packets whose destination address
is on the same segment as the source address. This confines network traffic to its respective domain and reduce the overall
load on the network.
The Switch performs "Store and forward" therefore, no error packets occur.
No packet loss will occur.
304
More reliably, it reduces the re-transmission rate.

7.5 Auto-Negotiation
The STP ports on the Switch have built-in "Auto-negotiation". This technology automatically sets the best possible bandwidth
when a connection is established with another network device (usually at Power On or Reset). This is done by detect the modes
and speeds at the second of both device is connected and capable of, both 10Base-T and 100Base-TX devices can connect
with the port in either Half- or Full-Duplex mode.
If attached device is:
100Base-TX port will set to:
10Mbps, no auto-negotiation
10Mbps.
10Mbps, with auto-negotiation

8. POWER OVER ETHERNET OVERVIEW
What is PoE?
Based on the global standard IEEE 802.3af, PoE is a technology for wired Ethernet, the most widely installed local area network
technology adopted today. PoE allows the electrical power necessary for the operation of each end-device to be carried by data
cables rather than by separate power cords. New network applications, such as IP Cameras, VoIP Phones, and Wireless
Networking, can help enterprises improve productivity. It minimizes wires that must be used to install the network for offering
lower cost, and less power failures.
IEEE802.3af also called Data Terminal equipment (DTE) power via Media dependent interface (MDI) is an international
standard to define the transmission for power over Ethernet. The 802.3af is delivering 48V power over RJ-45 wiring. Besides
802.3af also define two types of source equipment: Mid-Span and End-Span.
„
Mid-Span
Mid-Span device is placed between legacy switch and the powered device. Mid-Span is tap the unused wire pairs 4/5 and
7/8 to carry power, the other four is for data transmit.
„
End-Span
End-Span device is direct connecting with power device. End-Span could also tap the wire 1/2 and 3/6.
PoE System Architecture
The specification of PoE typically requires two devices: the Powered Source Equipment (PSE) and the Powered Device (PD).
The PSE is either an End-Span or a Mid-Span, while the PD is a PoE-enabled terminal, such as IP Phones, Wireless LAN, etc.
Power can be delivered over data pairs or spare pairs of standard CAT-5 cabling.
How Power is Transferred Through the Cable
A standard CAT5 Ethernet cable has four twisted pairs, but only two of these are used for 10BASE-T and 100BASE-T. The
specification allows two options for using these cables for power, shown in Figure 2 and Figure 3:
The spare pairs are used. Figure 2 shows the pair on pins 4 and 5 connected together and forming the positive supply, and the
pair on pins 7 and 8 connected and forming the negative supply. (In fact, a late change to the spec allows either polarity to be
used).
306
User’s Manual of WGSW-24040 / WGSW-24040R
SGSW-24040 / SGSW-24040R
Figure 1 - Power Supplied over the Spare Pins
The data pairs are used. Since Ethernet pairs are transformer coupled at each end, it is possible to apply DC power to the
center tap of the isolation transformer without upsetting the data transfer. In this mode of operation the pair on pins 3 and 6 and
the pair on pins 1 and 2 can be of either polarity.
Figure 2 - Power Supplied over the Data Pins
When to install PoE?
Consider the following scenarios:
• • You're planning to install the latest VoIP Phone system to minimize cabling building costs when your company moves into
new offices next month.
• • The company staff has been clamoring for a wireless access point in the picnic area behind the building so they can work on
their laptops through lunch, but the cost of electrical power to the outside is not affordable.
• • Management asks for IP Surveillance Cameras and business access systems throughout the facility, but they would rather
avoid another electrician's payment.

The PoE Provision Process
While adding PoE support to networked devices is relatively painless, it should be realized that power cannot simply be
transferred over existing CAT-5 cables. Without proper preparation, doing so may result in damage to devices that are not
designed to support provision of power over their network interfaces.
The PSE is the manager of the PoE process. In the beginning, only small voltage level is induced on the port's output, till a valid
PD is detected during the Detection period. The PSE may choose to perform classification, to estimate the amount of power to
be consumed by this PD. After a time-controlled start-up, the PSE begins supplying the 48 VDC level to the PD, till it is
physically or electrically disconnected. Upon disconnection, voltage and power shut down.
Since the PSE is responsible for the PoE process timing, it is the one generating the probing signals prior to operating the PD
and monitoring the various scenarios that may occur during operation.
All probing is done using voltage induction and current measurement in return.

Line Detection
Before power is applied, safety dictates that it must first be ensured that a valid PD is connected to the PSE's output. This
process is referred to as "line detection", and involves the PSE seeking a specific, 25 KΩ signature resistor. Detection of this
signature indicates that a valid PD is connected, and that provision of power to the device may commence.
308
User’s Manual of WGSW-24040 / WGSW-24040R
SGSW-24040 / SGSW-24040R
The signature resistor lies in the PD's PoE front-end, isolated from the rest of the the PD's circuitries till detection is certified.
Classification
Once a PD is detected, the PSE may optionally perform classification, to determine the maximal power a PD is to consume. The
PSE induces 15.5-20.5 VDC, limited to 100 mA, for a period of 10 to 75 ms responded by a certain current consumption by the
PD, indicating its power class.
The PD is assigned to one of 5 classes: 0 (default class) indicates that full 15.4 watts should be provided, 1-3 indicate various
required power levels and 4 is reserved for future use. PDs that do not support classification are assigned to class 0. Special
care must be employed in the definition of class thresholds, as classification may be affected by cable losses.
Classifying a PD according to its power consumption may assist a PoE system in optimizing its power distribution. Such a
system typically suffers from lack of power resources, so that efficient power management based on classification results may
reduce total system costs.
Start-up
Once line detection and optional classification stages are completed, the PSE must switch from low voltage to its full voltage
capacity (44-57 Volts) over a minimal amount of time (above 15 microseconds).
A gradual startup is required, as a sudden rise in voltage (reaching high frequencies) would introduce noise on the data lines.
Once provision of power is initiated, it is common for inrush current to be experienced at the PSE port, due to the PD’s input
capacitance. A PD must be designed to cease inrush current consumption (of over 350 mA) within 50 ms of power provision
startup.
Operation
During normal operation, the PSE provides 44-57 VDC, able to support a minimum of 15.4 watts power.
Power Overloads
The IEEE 802.3af standard defines handling of overload conditions. In the event of an overload (a PD drawing a higher power
level than the allowed 12.95 Watts), or an outright short circuit caused by a failure in cabling or in the PD, the PSE must shut
down power within 50 to 75 milliseconds, while limiting current drain during this period to protect the cabling infrastructure.
Immediate voltage drop is avoided to prevent shutdown due to random fluctuations.
Power Disconnection Scenarios
The IEEE 802.3af standard requires that devices powered over Ethernet be disconnected safely (i.e. power needs be shut down
within a short period of time following disconnection of a PD from an active port).
When a PD is disconnected, there is a danger that it will be replaced by a non-PoE-ready device while power is still on. Imagine
disconnecting a powered IP phone utilizing 48 VDC, then inadvertently plugging the powered Ethernet cable into a non-PoE
notebook computer. What’s sure to follow is not a pretty picture.
The standard defines two means of disconnection, DC Disconnect and AC Disconnect, both of which provide the same
309
User’s Manual of WGSW-24040 / WGSW-24040R
SGSW-24040 / SGSW-24040R
functionality - the PSE shutdowns power to a disconnected port within 300 to 400ms. The upper boundary is a physical human
limit for disconnecting one PD and reconnecting another.
DC Disconnect
DC Disconnect detection involves measurement of current. Naturally, a disconnected PD stops consuming current, which can
be inspected by the PSE. The PSE must therefore disconnect power within 300 to 400 ms from the current flow stop. The lower
time boundary is important to prevent shutdown due to random fluctuations.
AC Disconnect
This method is based on the fact that when a valid PD is connected to a port, the AC impedance measured on its terminals is
significantly lower than in the case of an open port (disconnected PD).
AC Disconnect detection involves the induction of low AC signal in addition to the 48 VDC operating voltage. The returned AC
signal amplitude is monitored by the PSE at the port terminals. During normal operation, the PD's relatively low impedance
lowers the returned AC signal while a sudden disconnection of this PD will cause a surge to the full AC signal level and will
indicate PD disconnection.

9. TROUBLE SHOOTING
This chapter contains information to help you solve problems. If the Ethernet Switch is not functioning properly, make sure the
Ethernet Switch was set up according to instructions in this manual.
■ The Link LED is not lit
Solution:
Check the cable connection and remove duplex mode of the Ethernet Switch
■ Some stations cannot talk to other stations located on the other port
Solution:
Please check the VLAN settings, trunk settings, or port enabled / disabled status.
■ Performance is bad
Solution:
Check the full duplex status of the Ethernet Switch.
If the Ethernet Switch is set to full duplex and the partner is set to half
duplex, then the performance will be poor. Please also check the in/out rate of the port.
■ Why the Switch doesn't connect to the network
Solution:
1.
Check the LNK/ACT LED on the switch
2.
Try another port on the Switch
3.
Make sure the cable is installed properly
4.
Make sure the cable is the right type
5.
Turn off the power. After a while, turn on power again
■ 100Base-TX port link LED is lit, but the traffic is irregular
Solution:
Check that the attached device is not set to dedicate full duplex. Some devices use a physical or software switch to change
duplex modes. Auto-negotiation may not recognize this type of full-duplex setting.
■ Switch does not power up
Solution:
1.
AC power cord not inserted or faulty
2.
Check that the AC power cord is inserted correctly
3.
Replace the power cord If the cord is inserted correctly, check that the AC power source is working by connecting a
different device in place of the switch.
4.
If that device works, refer to the next step.
5.
If that device does not work, check the AC power

APPENDEX B : GLOSSARY
A
ACE
ACE is an acronym for Access Control Entry. It describes access permission associated with a particular ACE ID.
There are three ACE frame types (Ethernet Type, ARP, and IPv4) and two ACE actions (permit and deny). The ACE
also contains many detailed, different parameter options that are available for individual application.
ACL
ACL is an acronym for Access Control List. It is the list table of ACEs, containing access control entries that specify
individual users or groups permitted or denied to specific traffic objects, such as a process or a program.
Each accessible traffic object contains an identifier to its ACL. The privileges determine whether there are specific
traffic object access rights.
ACL implementations can be quite complex, for example, when the ACEs are prioritized for the various situation. In
networking, the ACL refers to a list of service ports or network services that are available on a host or server, each with
a list of hosts or servers permitted or denied to use the service. ACL can generally be configured to control inbound
traffic, and in this context, they are similar to firewalls.
Aggregation
Using multiple ports in parallel to increase the link speed beyond the limits of a port and to increase the redundancy for
higher availability.
(Also Port Aggregation, Link Aggregation).
ARP
ARP is an acronym for Address Resolution Protocol. It is a protocol that used to convert an IP address into a physical
address, such as an Ethernet address. ARP allows a host to communicate with other hosts when only the Internet
address of its neighbors is known. Before using IP, the host sends a broadcast ARP request containing the Internet
address of the desired destination system.
Auto-Negotiation
315
User’s Manual of WGSW-24040 / WGSW-24040R
SGSW-24040 / SGSW-24040R
Auto-negotiation is the process where two different devices establish the mode of operation and the speed settings
that can be shared by those devices for a link.
D
DES
DES is an acronym for Data Encryption Standard. It provides a complete description of a mathematical algorithm for
encrypting (enciphering) and decrypting (deciphering) binary coded information.
Encrypting data converts it to an unintelligible form called cipher. Decrypting cipher converts the data back to its
original form called plaintext. The algorithm described in this standard specifies both enciphering and deciphering
operations which are based on a binary number called a key.
DHCP
DHCP is an acronym for Dynamic Host Configuration Protocol. It is a protocol used for assigning dynamic IP
addresses to devices on a network.
DHCP used by networked computers (clients) to obtain IP addresses and other parameters such as the default
gateway, subnet mask, and IP addresses of DNS servers from a DHCP server.
The DHCP server ensures that all IP addresses are unique, for example, no IP address is assigned to a second client
while the first client's assignment is valid (its lease has not expired). Therefore, IP address pool management is done
by the server and not by a human network administrator.
Dynamic addressing simplifies network administration because the software keeps track of IP addresses rather than
requiring an administrator to manage the task. This means that a new computer can be added to a network without the
hassle of manually assigning it a unique IP address.
DNS
DNS is an acronym for Domain Name System. It stores and associates many types of information with domain names.
Most importantly, DNS translates human-friendly domain names and computer hostnames into computer-friendly IP
addresses. For example, the domain name www.example.com might translate to 192.168.0.1.
DoS
DoS is an acronym for Denial of Service. In a denial-of-service (DoS) attack, an attacker attempts to prevent legitimate
users from accessing information or services. By targeting at network sites or network connection, an attacker may be
able to prevent network users from accessing email, web sites, online accounts (banking, etc.), or other services that
rely on the affected computer.
Dotted Decimal Notation
Dotted Decimal Notation refers to a method of writing IP addresses using decimal numbers and dots as separators

between octets.
An IPv4 dotted decimal address has the form x.y.z.w, where x, y, z, and w are decimal numbers between 0 and 255.
DSCP
DSCP is an acronym for Differentiated Services Code Point. It is a field in the header of IP packets for packet
classification purposes.
E
Ethernet Type
Ethernet Type, or EtherType, is a field in the Ethernet MAC header, defined by the Ethernet networking standard. It is
used to indicate which protocol is being transported in an Ethernet frame.
F
FTP
FTP is an acronym for File Transfer Protocol. It is a transfer protocol that uses the Transmission Control Protocol (TCP)
and provides file writing and reading. It also provides directory service and security features.
Fast Leave
IGMP snooping Fast Leave processing allows the switch to remove an interface from the forwarding-table entry without
first sending out group specific queries to the interface. The VLAN interface is pruned from the multicast tree for the
multicast group specified in the original leave message. Fast-leave processing ensures optimal bandwidth
management for all hosts on a switched network, even when multiple multicast groups are in use simultaneously.
H
HTTP
HTTP is an acronym for Hypertext Transfer Protocol. It is a protocol that used to transfer or convey information on the
World Wide Web (WWW).
HTTP defines how messages are formatted and transmitted, and what actions Web servers and browsers should take
in response to various commands. For example, when you enter a URL in your browser, this actually sends an HTTP
command to the Web server directing it to fetch and transmit the requested Web page. The other main standard that
controls how the World Wide Web works is HTML, which covers how Web pages are formatted and displayed.
Any Web server machine contains, in addition to the Web page files it can serve, an HTTP daemon, a program that is
designed to wait for HTTP requests and handle them when they arrive. The Web browser is an HTTP client, sending
requests to server machines. An HTTP client initiates a request by establishing a Transmission Control Protocol (TCP)
connection to a particular port on a remote host (port 80 by default). An HTTP server listening on that port waits for the
client to send a request message.

HTTPS
HTTPS is an acronym for Hypertext Transfer Protocol over Secure Socket Layer. It is used to indicate a secure HTTP
connection.
HTTPS provide authentication and encrypted communication and is widely used on the World Wide Web for
security-sensitive communication such as payment transactions and corporate logons.
HTTPS is really just the use of Netscape's Secure Socket Layer (SSL) as a sublayer under its regular HTTP
application layering. (HTTPS uses port 443 instead of HTTP port 80 in its interactions with the lower layer, TCP/IP.)
SSL uses a 40-bit key size for the RC4 stream encryption algorithm, which is considered an adequate degree of
encryption for commercial exchange.
I
ICMP
ICMP is an acronym for Internet Control Message Protocol. It is a protocol that generated the error response,
diagnostic or routing purposes. ICMP messages generally contain information about routing difficulties or simple
exchanges such as time-stamp or echo transactions. For example, the PING command uses ICMP to test an Internet
connection.
IEEE 802.1X
IEEE 802.1X is an IEEE standard for port-based Network Access Control. It provides authentication to devices
attached to a LAN port, establishing a point-to-point connection or preventing access from that port if authentication
fails. With 802.1X, access to all switch ports can be centrally controlled from a server, which means that authorized
users can use the same credentials for authentication from any point within the network.
IGMP
IGMP is an acronym for Internet Group Management Protocol. It is a communications protocol used to manage the
membership of Internet Protocol multicast groups. IGMP is used by IP hosts and adjacent multicast routers to establish
multicast group memberships. It is an integral part of the IP multicast specification, like ICMP for unicast connections.
IGMP can be used for online video and gaming, and allows more efficient use of resources when supporting these
uses.
IGMP Querier
A router sends IGMP Query messages onto a particular link. This router is called the Querier.
IMAP
IMAP is an acronym for Internet Message Access Protocol. It is a protocol for email clients to retrieve email messages
from a mail server.
318
User’s Manual of WGSW-24040 / WGSW-24040R
SGSW-24040 / SGSW-24040R
IMAP is the protocol that IMAP clients use to communicate with the servers, and SMTP is the protocol used to
transport mail to an IMAP server.
The current version of the Internet Message Access Protocol is IMAP4. It is similar to Post Office Protocol version 3
(POP3), but offers additional and more complex features. For example, the IMAP4 protocol leaves your email
messages on the server rather than downloading them to your computer. If you wish to remove your messages from
the server, you must use your mail client to generate local folders, copy messages to your local hard drive, and then
delete and expunge the messages from the server.
IP
IP is an acronym for Internet Protocol. It is a protocol used for communicating data across a internet network.
IP is a "best effort" system, which means that no packet of information sent over it is assured to reach its destination in
the same condition it was sent. Each device connected to a Local Area Network (LAN) or Wide Area Network (WAN) is
given an Internet Protocol address, and this IP address is used to identify the device uniquely among all other devices
connected to the extended network.
The current version of the Internet protocol is IPv4, which has 32-bits Internet Protocol addresses allowing for in
excess of four billion unique addresses. This number is reduced drastically by the practice of webmasters taking
addresses in large blocks, the bulk of which remain unused. There is a rather substantial movement to adopt a new
version of the Internet Protocol, IPv6, which would have 128-bits Internet Protocol addresses. This number can be
represented roughly by a three with thirty-nine zeroes after it. However, IPv4 is still the protocol of choice for most of
the Internet.
IPMC
IPMC is an acronym for IP MultiCast.
L
LACP
LACP is an IEEE 802.3ad standard protocol. The Link Aggregation Control Protocol, allows bundling several physical
ports together to form a single logical port.
LLDP
LLDP is an IEEE 802.1ab standard protocol. The Link Layer Discovery Protocol, is used for network discovery, and
works by having the units in the network exchanging information with their neighbors using LLDP frames.
M
MAC Table
Switching of frames is based upon the DMAC address contained in the frame. The switch builds up a table that maps
319
User’s Manual of WGSW-24040 / WGSW-24040R
SGSW-24040 / SGSW-24040R
MAC addresses to switch ports for knowing which ports the frames should go to ( based upon the DMAC address in
the frame ). This table contains both static and dynamic entries. The static entries are configured by the network
administrator if the administrator wants to do a fixed mapping between the DMAC address and switch ports.
The frames also contain a MAC address ( SMAC address ), which shows the MAC address of the equipment sending
the frame. The SMAC address is used by the switch to automatically update the MAC table with these dynamic MAC
addresses. Dynamic entries are removed from the MAC table if no frame with the corresponding SMAC address have
been seen after a configurable age time.
MD5
MD5 is an acronym for Message-Digest algorithm 5. MD5 is a message digest algorithm, used cryptographic hash
function with a 128-bit hash value. It was designed by Ron Rivest in 1991. MD5 is officially defined in RFC 1321 - The
MD5 Message-Digest Algorithm.
Mirroring
For debugging network problems or monitoring network traffic, the switch system can be configured to mirror frames
from multiple ports to a mirror port. (In this context, mirroring a frame is the same as copying the frame.)
Both incoming (source) and outgoing (destination) frames can be mirrored to the mirror port.
N
NetBIOS
NetBIOS is an acronym for Network Basic Input/Output System. It is a program that allows applications on separate
computers to communicate within a Local Area Network (LAN), and it is not supported on a Wide Area Network (WAN).
The NetBIOS giving each computer in the network both a NetBIOS name and an IP address corresponding to a
different host name, provides the session and transport services described in the Open Systems Interconnection (OSI)
model.
NFS
NFS is an acronym for Network File System. It allows hosts to mount partitions on a remote system and use them as
though they are local file systems.
NFS allows the system administrator to store resources in a central location on the network, providing authorized users
continuous access to them, which means NFS supports sharing of files, printers, and other resources as persistent
storage over a computer network.
O

SGSW-24040 / SGSW-24040R
Optional TLVs.
A LLDP frame contains multiple TLVs
For some TLVs it is configurable if the switch shall include the TLV in the LLDP frame. These TLVs are known as
optional TLVs. If an optional TLVs is disabled the corresponding information is not included in the LLDP frame.
P
PING
ping is a program that sends a series of packets over a network or the Internet to a specific computer in order to
generate a response from that computer. The other computer responds with an acknowledgment that it received the
packets. Ping was created to verify whether a specific computer on a network or the Internet exists and is connected.
ping uses Internet Control Message Protocol (ICMP) packets. The PING Request is the packet from the origin
computer, and the PING Reply is the packet response from the target.
Policer
A policer can limit the bandwidth of received frames. It is located in front of the ingress queue.
POP3
POP3 is an acronym for Post Office Protocol version 3. It is a protocol for email clients to retrieve email messages from
a mail server.
POP3 is designed to delete mail on the server as soon as the user has downloaded it. However, some
implementations allow users or an administrator to specify that mail be saved for some period of time. POP can be
thought of as a "store-and-forward" service.
An alternative protocol is Internet Message Access Protocol (IMAP). IMAP provides the user with more capabilities for
retaining e-mail on the server and for organizing it in folders on the server. IMAP can be thought of as a remote file
server.
POP and IMAP deal with the receiving of e-mail and are not to be confused with the Simple Mail Transfer Protocol
(SMTP). You send e-mail with SMTP, and a mail handler receives it on your recipient's behalf. Then the mail is read
using POP or IMAP. IMAP4 and POP3 are the two most prevalent Internet standard protocols for e-mail retrieval.
Virtually all modern e-mail clients and servers support both.
Private VLAN
In a private VLAN, communication between ports in that private VLAN is not permitted. A VLAN can be configured as a
private VLAN.
Q
321
User’s Manual of WGSW-24040 / WGSW-24040R
SGSW-24040 / SGSW-24040R
QCE
QCE is an acronym for QoS Control Entry. It describes QoS class associated with a particular QCE ID.
There are six QCE frame types: Ethernet Type, VLAN, UDP/TCP Port, DSCP, TOS, and Tag Priority. Frames can be
classified by one of 4 different QoS classes: "Low", "Normal", "Medium", and "High" for individual application.
QCL
QCL is an acronym for QoS Control List. It is the list table of QCEs, containing QoS control entries that classify to a
specific QoS class on specific traffic objects.
Each accessible traffic object contains an identifier to its QCL. The privileges determine specific traffic object to specific
QoS class.
QoS
QoS is an acronym for Quality of Service. It is a method to guarantee a bandwidth relationship between individual
applications or protocols.
A communications network transports a multitude of applications and data, including high-quality video and
delay-sensitive data such as real-time voice. Networks must provide secure, predictable, measurable, and sometimes
guaranteed services.
Achieving the required QoS becomes the secret to a successful end-to-end business solution. Therefore, QoS is the
set of techniques to manage network resources.
R
RARP
RARP is an acronym for Reverse Address Resolution Protocol. It is a protocol that is used to obtain an IP address for a
given hardware address, such as an Ethernet address. RARP is the complement of ARP.
Router Port
A router port is a port on the Ethernet switch that leads switch towards the Layer 3 multicast device.
RSTP
In 1998, the IEEE with document 802.1w introduced an evolution of STP: the Rapid Spanning Tree Protocol, which
provides for faster spanning tree convergence after a topology change. Standard IEEE 802.1D-2004 now incorporates
RSTP and obsoletes STP, while at the same time being backwards-compatible with STP.
S
SAMBA
322
User’s Manual of WGSW-24040 / WGSW-24040R
SGSW-24040 / SGSW-24040R
Samba is a program running under UNIX-like operating systems that provides seamless integration between UNIX and
Microsoft Windows machines. Samba acts as file and print servers for Microsoft Windows, IBM OS/2, and other SMB
client machines. Samba uses the Server Message Block (SMB) protocol and Common Internet File System (CIFS),
which is the underlying protocol used in Microsoft Windows networking.
Samba can be installed on a variety of operating system platforms, including Linux, most common Unix platforms,
OpenVMS, and IBM OS/2.
Samba can also register itself with the master browser on the network so that it would appear in the listing of hosts in
Microsoft Windows "Neighborhood Network".
SHA
SHA is an acronym for Secure Hash Algorithm. It designed by the National Security Agency (NSA) and published by
the NIST as a U.S. Federal Information Processing Standard. Hash algorithms compute a fixed-length digital
representation (known as a message digest) of an input data sequence (the message) of any length.
Shaper
A shaper can limit the bandwidth of transmitted frames. It is located after the ingress queues.
SMTP
SMTP is an acronym for Simple Mail Transfer Protocol. It is a text-based protocol that uses the Transmission Control
Protocol (TCP) and provides a mail service modeled on the FTP file transfer service. SMTP transfers mail messages
between systems and notifications regarding incoming mail.
SNMP
SNMP is an acronym for Simple Network Management Protocol. It is part of the Transmission Control Protocol/Internet
Protocol (TCP/IP) protocol for network management. SNMP allow diverse network objects to participate in a network
management architecture. It enables network management systems to learn network problems by receiving traps or
change notices from network devices implementing SNMP.
SNTP
SNTP is an acronym for Simple Network Time Protocol, a network protocol for synchronizing the clocks of computer
systems. SNTP uses UDP (datagrams) as transport layer.
SPROUT
Stack Protocol using ROUting Technology. An advanced protocol for almost instantaneous discovery of topology
changes within a stack as well as election of a master switch. SPROUT also calculates parameters for setting up each
switch to perform shortest path forwarding within the stack.
STP
Spanning Tree Protocol is an OSI layer-2 protocol which ensures a loop free topology for any bridged LAN. The
original STP protocol is now obsoleted by RSTP.
323
User’s Manual of WGSW-24040 / WGSW-24040R
SGSW-24040 / SGSW-24040R
Switch ID
Switch IDs (1-16) are used to uniquely identify the switches within a stack. The Switch ID of each switch is shown on
the display on the front of the switch and is used widely in the web pages as well as in the CLI commands.
T
Tag Priority
Tag Priority is a 3-bit field storing the priority level for the 802.1Q frame.
TCP
TCP is an acronym for Transmission Control Protocol. It is a communications protocol that uses the Internet Protocol
(IP) to exchange the messages between computers.
The TCP protocol guarantees reliable and in-order delivery of data from sender to receiver and distinguishes data for
multiple connections by concurrent applications (for example, Web server and e-mail server) running on the same
host.
The applications on networked hosts can use TCP to create connections to one another. It is known as a
connection-oriented protocol, which means that a connection is established and maintained until such time as the
message or messages to be exchanged by the application programs at each end have been exchanged. TCP is
responsible for ensuring that a message is divided into the packets that IP manages and for reassembling the packets
back into the complete message at the other end.
Common network applications that use TCP include the World Wide Web (WWW), e-mail, and File Transfer Protocol
(FTP).
TELNET
TELNET is an acronym for TELetype NETwork. It is a terminal emulation protocol that uses the Transmission Control
Protocol (TCP) and provides a virtual connection between TELNET server and TELNET client.
TELNET enables the client to control the server and communicate with other servers on the network. To start a Telnet
session, the client user must log in to a server by entering a valid username and password. Then, the client user can
enter commands through the Telnet program just as if they were entering commands directly on the server console.
TFTP
TFTP is an acronym for Trivial File Transfer Protocol. It is transfer protocol that uses the User Datagram Protocol (UDP)
and provides file writing and reading, but it does not provides directory service and security features.
ToS
ToS is an acronym for Type of Service. It is implemented as the IPv4 ToS priority control. It is fully decoded to
determine the priority from the 6-bit ToS field in the IP header. The most significant 6 bits of the ToS field are fully
324
User’s Manual of WGSW-24040 / WGSW-24040R
SGSW-24040 / SGSW-24040R
decoded into 64 possibilities, and the singular code that results is compared against the corresponding bit in the IPv4
ToS priority control bit (0~63).
TLV
A LLDP frame can contain multiple pieces of information. Each of these pieces of information is known as TLV (TLV is
short for "Type Length Value").
U
UDP
UDP is an acronym for User Datagram Protocol. It is a communications protocol that uses the Internet Protocol (IP) to
exchange the messages between computers.
UDP is an alternative to the Transmission Control Protocol (TCP) that uses the Internet Protocol (IP). Unlike TCP, UDP
does not provide the service of dividing a message into packet datagrams, and UDP doesn't provide reassembling and
sequencing of the packets. This means that the application program that uses UDP must be able to make sure that the
entire message has arrived and is in the right order. Network applications that want to save processing time because
they have very small data units to exchange may prefer UDP to TCP.
UDP provides two services not provided by the IP layer. It provides port numbers to help distinguish different user
requests and, optionally, a checksum capability to verify that the data arrived intact.
Common network applications that use UDP include the Domain Name System (DNS), streaming media applications
such as IPTV, Voice over IP (VoIP), and Trivial File Transfer Protocol (TFTP).
User Priority
User Priority is a 3-bit field storing the priority level for the 802.1Q frame.
V
VLAN
Virtual LAN. A method to restrict communication between switch ports. VLANs can be used for the following
applications:
VLAN unaware switching: This is the default configuration. All ports are VLAN unaware with Port VLAN ID 1 and
members of VLAN 1. This means that MAC addresses are learned in VLAN 1, and the switch does not remove or
insert VLAN tags.
VLAN aware switching: This is based on the IEEE 802.1Q standard. All ports are VLAN aware. Ports connected to
VLAN aware switches are members of multiple VLANs and transmit tagged frames. Other ports are members of one
VLAN, set up with this Port VLAN ID, and transmit untagged frames.
325
User’s Manual of WGSW-24040 / WGSW-24040R
SGSW-24040 / SGSW-24040R
Provider switching: This is also known as Q-in-Q switching. Ports connected to subscribers are VLAN unaware,
members of one VLAN, and set up with this unique Port VLAN ID. Ports connected to the service provider are VLAN
aware, members of multiple VLANs, and set up to tag all frames. Untagged frames received on a subscriber port are
forwarded to the provider port with a single VLAN tag. Tagged frames received on a subscriber port are forwarded to
the provider port with a double VLAN tag.
VLAN ID
VLAN ID is a 12-bit field specifying the VLAN to which the frame belongs.
