1.2 Product Description

Ideal Solution for Secure IP Surveillance Infrastructure

Particularly designed for the growing popular IP surveillance applications, IFS ES2402 SERIES 802.3at PoE web smart switch

is positioned as a surveillance switch with the central management of remote power control and IP camera monitoring. The

ES2402 SERIES provides intelligent PoE functions along with 8/16/24 10/100BASE-TX ports featuring 30-watt 802.3at PoE+

with RJ45 copper interfaces and 2 Gigabit TP/SFP combo interfaces supporting high-speed transmission of surveillance

images and videos.

Perfectly-integrated Solution for PoE IP Camera and NVR System

Being different from the general IT industry PoE switch which usually contains 8, 16 or 24 PoE ports, the ES2402 SERIES

provides 8/16/24 802.3at PoE+ ports for catering to medium to large scale of IP surveillance networks at a lower total cost. With

its 5.6Gbps/7.2Gbps/8.8Gbps high-performance switch architecture and 120-watt/220-watt/360-watt PoE power budget, the

recorded video files from 8/16/24 PoE IP cameras can be powered by the ES2402 SERIES and saved in the 8/16-channel NVR

systems or surveillance software to perform comprehensive security monitoring. For instance, one ES2402 SERIES can be

combined with one 8/16-channel NVR and 8/16 PoE IP cameras as a kit for the administrators to centrally and efficiently

manage the surveillance system in the local LAN and the remote site via Internet. Please refer to following ES2402 SERIES

application example.

8

Intelligent LED Indicator for Real-time PoE Usage

The ES2402 SERIES helps users to monitor the current status of PoE power usage easily and efficiently by its advanced LED

indication. Called “PoE Power Usage”, the front panel of the ES2402 SERIES Fast Ethernet PoE+ Switch has four orange

LEDs indicating PoE power usage.

Robust Layer 2 Features

The ES2402 SERIES can be programmed for advanced switch management functions such as dynamic port link aggregation

(LACP), Spanning Tree Protocol (STP), IGMP Snooping v1, v2, bandwidth control and L2/L4 security control. The ES2402

SERIES provides IEEE 802.1Q tagged VLAN, port-based VLAN and MTU VLAN. Via aggregation of supporting ports, the

ES2402 SERIES allows the operation of a high-speed trunk combining multiple ports and supports fail-over as well.

Flexible and Extendable Uplink Solution

The ES2402 SERIES provides 2 extra Gigabit TP/SFP combo interfaces supporting 10/100/1000BASE-T RJ45 copper to

connect with surveillance network devices such as NVR, Video Streaming Server or NAS to facilitate surveillance

management. It can be connected with the 1000BASE-SX/LX SFP (Small Form-factor Pluggable) fiber transceiver and uplinks

to backbone switch for monitoring control center in long distance. The distance can be extended from 550m to 2km (multi-mode

fiber), even going up to above 10/20/30/50/60/70km (single-mode fiber or WDM fiber). They are well suited for applications

within the enterprise data centers and distributions.

2.2.3 Installing the SFP transceiver

The sections describe how to insert an SFP transceiver into an SFP slot.

The SFP transceivers are hot-pluggable and hot-swappable. You can plug in and out the transceiver to/from any SFP port

without having to power down the PoE Web Smart Switch, as the Figure 2-5 shows.

Figure 2-5 Plug in the SFP transceiver

 Approved IFS SFP Transceivers

IFS PoE Web Smart Switch supports both Single mode and Multi-mode SFP transceiver. The following list of approved IFS SFP

transceivers is correct at the time of publication:

Fast Ethernet Transceiver (100Base-X SFP)

Gigabit Ethernet Transceiver (1000BASX-LX-BX, Fiber Bi-Directional SFP)

26

It is recommended to use IFS SFP on the PoE Web Smart Switch. If you insert an SFP transceiv

er

that is not supported, the PoE Web Smart Switch will not recognize it.

1. Before we connect PoE Web Smart Switch to the other network device, we have to make sure both sides of the SFP

transceivers are with the same media type, for example: 1000BASE-SX to 1000BASE-SX, 1000Bas-LX to 1000BASE-LX.

2. Check whether the fiber-optic cable type matches with the SFP transceiver requirement.

 To connect to 1000BASE-SX SFP transceiver, please use the multi-mode fiber cable with one side being the male

duplex LC connector type.

 To connect to 1000BASE-LX SFP transceiver, please use the single-mode fiber cable with one side being the male

duplex LC connector type.

 Connect the Fiber Cable

1. Insert the duplex LC connector into the SFP transceiver.

2. Connect the other end of the cable to a device with SFP transceiver installed.

3. Check the LNK/ACT LED of the SFP slot on the front of the PoE Web Smart Switch. Ensure that the SFP transceiver is

operating correctly.

4. Check the Link mode of the SFP port if the link fails. To function with some fiber-NICs or Media Converters, user has to set

the port Link mode to “1000 Force”.

 Remove the Transceiver Module

1. Make sure there is no network activity anymore.

2. Remove the Fiber-Optic Cable gently.

3. Lift up the lever of the SFP module and turn it to a horizontal position.

4. Pull out the module gently through the lever.

Figure 2-8 How to Pull Out the SFP Transceiver

27

Never pull out the module without lifting up the lever of the module and turning it to a

horizontal position. Directly pulling out

the module could damage the module and the SFP

module slot of the PoE Web Smart Switch.

3. SWITCH MANAGEMENT

This chapter explains the methods that you can use to configure management access to the PoE Web Smart Switch. It

describes the types of management applications and the communication and management protocols that deliver data between

your management device (workstation or personal computer) and the system. It also contains information about port connection

options.

This chapter covers the following topics:

 Requirements

 Management Access Overview

 Web Management Access

 SNMP Access

 Standards, Protocols, and Related Readings

3.1 Requirements

 Workstations running Windows 2000/XP, 2003, Vista/7/8, 2008, MAC OS9 or later, Linux, UNIX or other platforms

are compatible with TCP/IP protocols.

 Workstation is installed with Ethernet NIC (Network Interface Card)

 Ethernet Port connection

• Network cables -- Use standard network (UTP) cables with RJ45 connectors.

 The above Workstation is installed with Web Browser and JAVA runtime environment Plug-in

1. It is recommended to use Internet Explore 8.0 or above to access PoE Web Smart Switch

.

2. Because of WEB UI operation method is same for all ES2402 SERIES.

28

3.2 Management Access Overview

The PoE Web Smart Switch gives you the flexibility to access and manage it using any or all of the following methods:

 Web browser interface

 An external SNMP-based network management application

The Web browser management is embedded in the PoE Web Smart Switch software and available for immediate use. Each of

these management methods has their own advantages. Table 3-1 compares the three management methods.

Method Advantages Disadvantages

Web Browser  Ideal for configuring the switch

remotely

 Compatible with all popular

browsers

 Can be accessed from any location

 Most visually appealing

 Security can be compromised (hackers

need to know only the IP address and

subnet mask)

 May encounter lag times on poor

connections

SNMP Agent  Communicates with switch functions

at the MIB level

 Based on open standards

 Requires SNMP manager software

 Least visually appealing of all three

methods

 Some settings require calculations

 Security can be compromised (hackers

need to know only the community name)

Table 3-1 Comparison of Management Methods

3.3 Web Management

The PoE Web Smart Switch offers management features that allow users to manage the PoE Web Smart 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 PoE Web Smart Switch's Web interface applications directly in your Web browser by entering the IP address

of the PoE Web Smart Switch.

Figure 3-1 Web Management

29

You can then use your Web browser to list and manage the PoE Web Smart Switch configuration parameters from one central

location, just as if you were directly connected to the PoE Web Smart Switch's console port. Web Management requires

Microsoft Internet Explorer 8.0 or later.

Figure 3-2 Web Main Screen of the PoE Web Smart Switch

3.4 SNMP-based Network Management

You can use an external SNMP-based application to configure and manage the PoE Web Smart 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 Network 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 setting gets and sets community strings for the PoE Web

Smart Switch are public.

Figure 3-4 SNMP Management

4. WEB CONFIGURATION

This section introduces the configuration and functions of the Web-based management.

About Web-based Management

The PoE Web Smart Switch offers management features that allow users to manage the PoE Web Smart Switch from anywhere

on the network through a standard browser such as Microsoft Internet Explorer.

The Web-based Management supports Internet Explorer 8.0. 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, IE8.0 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 PoE Web Smart Switch can be configured through an Ethernet connection, making sure the manager PC must be set on

the same IP subnet address as the PoE Web Smart Switch.

For example, the default IP address of the PoE Web Smart 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 PoE Web Smart 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.

4.4 VLAN

4.4.1 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.

Port-based VLAN

Port-based VLAN limit traffic that flows into and out of switch ports. Thus, all devices connected to a port are members of

the VLAN(s) the port belongs to, whether there is a single computer directly connected to a switch, or an entire

department.

50

On port-based VLAN, NICs do not need to be able to identify 802.1Q tags in packet headers. NICs send and receive

normal Ethernet packets. If the packet's destination lies on the same segment, communications take place using normal

Ethernet protocols. Even though this is always the case, when the destination for a packet lies on another switch port,

VLAN considerations come into play to decide if the packet is dropped by the Switch or delivered.

IEEE 802.1Q Tag-based VLAN

IEEE 802.1Q (tagged) VLAN is implemented on the Switch. 802.1Q VLAN requires 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.

Any port can be configured as either tagging or untagging. The untagging feature of IEEE 802.1Q VLAN allows VLAN to

work with legacy switches that don’t recognize VLAN tags in packet headers. The tagging feature allows VLAN to span

multiple 802.1Q-compliant switches through a single physical connection and allows Spanning Tree to be enabled on all

ports and work normally.

Some relevant terms:

Ta g - The act of putting 802.1Q VLAN information into the header of a packet.

Untag - The act of stripping 802.1Q VLAN information out of the packet header.

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 PoE Web Smart 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 PoE Web Smart 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.

4.5 Quality of Service

4.5.1 QoS overview

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.

The QoS page of the PoE Web Smart Switch contains three types of QoS mode – the First-In-First-Out mode,

All-High-before-Low mode or Weighted-Round-Robin mode can be selected. All the three modes rely on predefined fields

within the packet to determine the output queue.

 First-In-First-Out Mode –The output queue assignment is determined with first-come, first-served (FCFS) behaviour.

 All-High-before-Low Mode - The output queue assignment is determined by the To S or CoS field in the packets with strict

priority.

 Weighted-Round-Robin Mode –The output queue assignment is determined by the ToS or CoS field in the packets with

scheduling discipline policy.

The PoE Web Smart Switch supports eight priority level queues; the queue service rate is based on the WRR (Weight Round

Robin). The WRR ratio of high-priority and low-priority can be set to 4:1 or 8:1 or any.

4.7 Spanning Tree

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 port identifier

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

64

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 Statuses

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 statuses:

 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 status 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

65

Figure 4-7-1 STP Port Status Transitions

You can modify each port status by using management software. When you enable STP, every port on every switch in the

network goes through the blocking status and then transitions through the statuses of listening and learning at power up. If

properly configured, each port stabilizes to the forwarding or blocking statis. No packets (except BPDUs) are forwarded from, or

received by, STP enabled ports until the forwarding status 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:

Parameter Description Default Value

Bridge Identifier(Not user

except by setting priority

A combination of the User-set priority and

the switch’s MAC address.

The Bridge Identifier consists of two parts:

numbers give a higher priority and a greater

chance of a given switch being elected as

32768

Hello Time The length of time between broadcasts of

the hello message by the switch

Maximum Age Timer Measures the age of a received BPDU for a

port and ensures that the BPDU is discarded

when its age exceeds the value of the

maximum age timer.

20 seconds

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.

67

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

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 status while moving from the blocking status to the forwarding status.

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.

68

Figure 4-7-2 Before Applying the STA Rules

In this example, only the default STP values are used.

Figure 4-7-3 After Applying the STA Rules

69

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 = 20,000) 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 = 200,000). 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 Trunking Setting

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 following is the example of Aggregation links:

 Static LAGs (Port Trunk) – Force aggregared selected ports to be a trunk group.

 Link Aggregation Control Protocol (LACP) LAGs - LACP LAG negotiate Aggregated Port links with other

LACP ports located on a different device. If the other device ports are also LACP ports, the devices establish

a LAG between them.

Figure 4-8-1 Link Aggregation

76

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 8 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 (RJ45, 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 8 ports to be aggregated at the same time. The PoE Web Smart Switch support Gigabit Ethernet ports

(up to 8 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.

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. However, to improve power management

at the PSE, the PD provides a signature about Class level.

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.

A PD will return Class 0 to 4 in accordance with the maximum power draw as specified by Table 4-10-1.

4.9.2 PoE Status

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.

4.12 SNMP

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.

• 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.

1. Get -- Allows the NMS to retrieve an object instance from the agent.

2. Set -- Allows the NMS to set values for object instances within an agent.

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:

• Read = public

5. SWITCH OPERATION

5.1 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.

5.2 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.

5.3 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

5.4 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. More reliably, it reduces the re-transmission rate.

No packet loss will occur.

92

5.5 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 10/20Mbps (10BASE-T/Full-Duplex)

100Mbps, no auto-negotiation 100Mbps

100Mbps, with auto-negotiation 100/200Mbps (100BASE-TX/Full-Duplex)

6. Power over Ethernet Overview

What is PoE?

The PoE is an abbreviation of Power over Ethernet; the PoE technology means a system to pass electrical power safely, along

with data on Ethernet UTP cable. The IEEE standard for PoE technology requires Category 5 cable or higher for high power

PoE levels, but can operate with category 3 cable for low power levels. Power is supplied in common mode over two or more of

the differential pairs of wires found in the Ethernet cables and comes from a power supply within a PoE-enabled networking

device such as an Ethernet switch or can be injected into a cable run with a mid-span power supply.

The original IEEE 802.3af-2003 PoE standard provides up to 15.4 W of DC power (minimum 44 V DC and 350mA) to each

device. Only 12.95 W is assured to be available at the powered device as some power is dissipated in the cable. The updated

IEEE 802.3at-2009 PoE standard also known as PoE+ or PoE plus, provides up to 25.5 W of power. The 2009 standard

prohibits a powered device from using all four pairs for power. The 802.3af / 802.3at 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.

93

Powered Source Equipment (PSE)

Power sourcing equipment (PSE) is a device such as a switch

that provides (sources) power on the Ethernet cable. The

maximum allowed continuous output power per cable in IEEE 802.3af is 15.40 W. A later specification, IEEE 802.3at, offers

25.50 W. When the device is a switch, it is commonly called an End-span (although IEEE 802.3af refers to it as endpoint).

Otherwise, if it's an intermediary device between a non PoE capable switch and a PoE device, it's called a Mid-span. An

external PoE injector is a Mid-span device

.

Powered device

A powered device (PD) is a device powered by a PSE and thus consumes energy. Examples include wireless access points, IP

Phones, and IP cameras. Many powered devices have an auxiliary power connector for an optional, external, power supply.

Depending on the PD design, some, none, or all power can be supplied from the auxiliary port, with the auxiliary port sometimes

acting as backup power in case of PoE supplied power failure.

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-TX. The

specification allows two options for using these cables for power, shown in Figure 1 and Figure 2:

The spare pairs are used. Figure 1 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).

Figure 6-1: 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.

7. TROUBLESHOOTING

This chapter contains information to help you solve your issue. If the PoE Web Smart Switch is not functioning properly, make

sure the PoE Web Smart Switch is 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 PoE Web Smart 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 PoE Web Smart Switch. If the PoE Web Smart 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 PoE Web Smart Switch

2. Try another port on the PoE Web Smart 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:

 AC power cord not inserted or faulty

 Check whether the AC power cord is inserted correctly

 Replace the power cord if the cord is inserted correctly; check whether the AC power source is working by

connecting a different device in place of the switch.

 If that device works, refer to the next step.

 If that device does not work, check the AC pow

Implicit implementation of the crossover function within a twisted-pair cable, or at a wiring panel, while not expressly forbidden,

is beyond the scope of this standard.

A.2 10/100Mbps, 10/100BASE-TX

When connecting your 10/100Mbps Ethernet Switch to another switch, a bridge or a hub, a straight or crossover cable is

necessary. Each port of the Switch supports auto-MDI/MDI-X detection. That means you can directly connect the Switch to any

Ethernet devices without making a crossover cable. The following table and diagram show the standard RJ45 receptacle/

connector and their pin assignments:
