3. Network Application

This chapter provides some sample applications to help user to have more actual idea of Industrial Switch function

application. A sample application of the industrial switch is as below:

 Factory Redundant Ring Application



Transportation Networking and Public Wireless Service

User’s Manual of ISW-1022M Series and ISW-1033MT

3.1 Rapid Ring Application

The industrial Switch supports the Rapid Ring (X-Ring) protocol that can help the network system to recovery from

network connection failure within 20ms or less, and make the network system more reliable. The X-Ring algorithm is

similar to spanning tree protocol (STP) algorithm but its recovery time is faster than STP. The following figure is a sample

X-Ring application.

3.2 Coupling Ring Application

In the network, it may have more than one X-Ring group. By using the coupling ring function, it can connect each X-Ring

for the redundant backup. It can ensure the transmissions between two ring groups not to fail. The following figure is a

sample of coupling ring application.

User’s Manual of ISW-1022M Series and ISW-1033MT

3.3 Dual Homing Application

Dual Homing function is to prevent the connection lose from between X-Ring group and upper level/core switch. Assign

two ports to be the Dual Homing port that is backup port in the X-Ring group. The Dual Homing function only works when

the X-Ring function is active. Each X-Ring group only has one Dual Homing port.

In Dual Homing application architecture, the upper level switches need to enable the Rapid

Spanning Tree protocol.

5. Web-Based Management

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

5.1 About Web-based Management

The Managed Industrial Switch offers management features that allow users to manage the Managed Industrial 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 following screen based on ISW-1022M. For ISW-1022M series and ISW-1033MT, the WEB

UI display will be the same as ISW-1022M. The PoE function and Digital Inputs / Outputs function

will be described additional.

The Managed Industrial 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 Industrial Switch.

For example, the default IP address of the Managed Industrial 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 Industrial 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.

to decide a means of assigning IP address to the switch.

The page includes the following fields:

Object Description

DHCP Client:

IP Address:

Figure 5-4 IP configuration interface

Enable or disable the DHCP client function. When DHCP client function is

enabled, the switch will be assigned an IP address from the network DHCP

server. The default IP address will be replaced by the assigned IP address on

DHCP server. After the user clicks Apply, a popup dialog shows up to inform the

user that when the DHCP client is enabled, the current IP will lose and user

should find the new IP on the DHCP server.

Assign the IP address that the network is using. If DHCP client function is

enabled, this switch is configured as a DHCP client. The network DHCP server

will assign the IP address to the switch and display it in this column.

The default IP is 192.168.0.100 or the user has to assign an IP address

manually when DHCP Client is disabled.

5.4.3 DHCP Server

DHCP is the abbreviation of Dynamic Host Configuration Protocol that is a protocol for assigning dynamic IP

addresses to devices on a network. With dynamic addressing, a device can have a different IP address every time it

connects to the network. In some systems, the device's IP address can even change while it is still connected. DHCP also

supports a mix of static and dynamic IP addresses. 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.

The system provides the DHCP server function. Having enabled the DHCP server function, the switch system will be

configured as a DHCP server.

5.4.3.1 System configuration

The Dynamic Host Configuration Protocol (DHCP) Server gives out IP addresses when a device is booting up and request

an IP to logged on to the network. It must be set as a DHCP client to obtain the IP address automatically.

For example, dynamic IP is in the range between 192.168.0.101 ~

192.168.0.200. In contrast, 192.168.0.101 is the Low IP address.

Type in an IP address. High IP address is the end of the dynamic IP range. For

example, dynamic IP is in the range between 192.168.0.101 ~ 192.168.0.200. In

contrast, 192.168.0.200 is the High IP address.

Type in the subnet mask of the IP configuration.

Type in the IP address of the gateway in your network.

Type in the Domain Name Server IP Address in your network.

It is the time period that system will reset the dynamic IP assignment to ensure

the dynamic IP will not been occupied for a long time or the server doesn’t know

that the dynamic IP is idle.

When the DHCP server function is enabled, the system will collect the DHCP client information including the assigned IP

address, the MAC address of the client device, the IP assigning type, status and lease time.

5.4.7 SNTP Configuration

SNTP (Simple Network Time Protocol) is a simplified version of NTP which is an Internet protocol used to synchronize

the clocks of computers to some time reference. Because time usually just advances, the time on different node stations

will be different. With the communicating programs running on those devices, it would cause time to jump forward and

back, a non-desirable effect. Therefore, the switch provides comprehensive mechanisms to access national time and

frequency dissemination services, organize the time-synchronization subnet and the local clock in each participating

subnet peer.

Daylight saving time (DST) is the convention of advancing clocks so that afternoons have more daylight and mornings

have less. Typically clocks are adjusted forward one hour near the start of spring and are adjusted backward in autumn.

For example, key in ‘20070701 02:00’ and ‘20071104 02:04’ in the two column

fields respectively to represent that DST begins at 2:00 a.m. on March 11, 2007

and ends at 2:00 a.m. on November 4, 2007.

For non-US and European countries, specify the amount of time for day light

savings. Please key in the valid figure in the range of minute between 0 and 720,

which means you can set the offset up to 12 hours.

Whether or not the receiving node sends feedback to the sending node is

determined by this item. When enabled, once the device exceeds the input data

rate of another device, the receiving device will send a PAUSE frame which halts

the transmission of the sender for a specified period of time. When disabled, the

receiving device will drop the packet if too much to process.

When the Security selection is set as ‘On’, any access from the device which

connects to this port will be blocked unless the MAC address of the device is

included in the static MAC address table. See the segment of MAC Address Table—Static MAC Addresses.

Port trunking is the combination of several ports or network cables to expand the connection speed beyond the limits of

any one single port or network cable. Link Aggregation Control Protocol (LACP), which is a protocol running on layer 2, provides a standardized means in accordance with IEEE 802.3ad to bundle several physical ports together to form a

single logical channel. All the ports within the logical channel or so-called logical aggregator work at the same connection

speed and LACP operation requires full-duplex mode.

When enabled, the trunk group is using LACP. A port which joins an LACP trunk

group has to make an agreement with its member ports first. Please notice that a

trunk group, including member ports split between two switches, has to enable

the LACP function of the two switches. When disabled, the trunk group is a static

trunk group. The advantage of having the LACP disabled is that a port joins the

trunk group without any handshaking with its member ports; but member ports

won’t know that they should be aggregated together to form a logic trunk group.

5.6.1.1 VLAN Overview

A Virtual LAN (VLAN) is a logical network grouping that limits the broadcast domain. It allows you to isolate network traffic

so only members of the VLAN receive traffic from the same VLAN members. Basically, creating a VLAN from a switch is

logically equivalent of reconnecting a group of network devices to another Layer 2 switch. However, all the network

devices are still plug into the same switch physically.

The Managed Industrial Switch supports IEEE 802.1Q (tagged-based) and Port-Base VLAN setting in web management page. In the default configuration, VLAN support is “Disable”.

 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.

On port-based VLAN.NIC do not need to be able to identify 802.1Q tags in packet headers. NIC 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 VLANs

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.

User’s Manual of ISW-1022M Series and ISW-1033MT

 The tagging feature allows VLAN to span multiple 802.1Q-compliant switches through a single physical

connection and allows Spanning Tree to be enabled on all ports and work normally.

Some relevant terms:

Tagging - The act of putting 802.1Q VLAN information into the header of a packet. Untagging - The act of stripping 802.1Q VLAN information out of the packet header.

 802.1Q VLAN Tags

The figure below shows the 802.1Q VLAN tag. There are four additional octets inserted after the source MAC address.

Their presence is indicated by a value of 0x8100 in the Ether Type field. When a packet's Ether Type field is equal to

0x8100, the packet carries the IEEE 802.1Q/802.1p tag. The tag is contained in the following two octets and consists of 3

bits of user priority, 1 bit of Canonical Format Identifier (CFI - used for encapsulating Token Ring packets so they can be

carried across Ethernet backbones), and 12 bits of VLAN ID (VID). The 3 bits of user priority are used by 802.1p. The VID

is the VLAN identifier and is used by the 802.1Q standard. Because the VID is 12 bits long, 4094 unique VLAN can be

identified.

The tag is inserted into the packet header making the entire packet longer by 4 octets. All of the information originally

contained in the packet is retained.

 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."

User’s Manual of ISW-1022M Series and ISW-1033MT

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 Switch supports Port-based VLAN and 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.

5.6.1.2 VLAN Configuration

A Virtual LAN (VLAN) is a logical network grouping that limits the broadcast domain. It allows you to isolate network traffic

so only members of the VLAN receive traffic from the same VLAN members. Basically, creating a VLAN from a switch is

logically equivalent of reconnecting a group of network devices to another Layer 2 switch. However, all the network

devices are still plug into the same switch physically.

The Industrial Switch supports Port-based, 802.1Q (Tagged-based) and GVRP VLAN in web management page. In the default configuration, VLAN support is “Disable”.

5.6.1.3 Port-based VLAN

Figure 5-30 VLAN Configuration interface

A port-based VLAN basically consists of its members—ports, which means the VLAN is created by grouping the selected

ports. This method provides the convenience for users to configure a simple VLAN easily without complicated steps.

Packets can go among only members of the same VLAN group. Note all unselected ports are treated as belonging to

another single VLAN. If the port-based VLAN enabled, the VLAN-tagging is ignored. The port-based VLAN function allows

the user to create separate VLANs to limit the unnecessary packet flooding; however, for the purpose of sharing resource,

a single port called a common port can belongs to different VLANs, which all the member devices (ports) in different

VLANs have the permission to access the common port while they still cannot communicate with each other in different

VLANs.

5.6.1.4 802.1Q VLAN

Virtual Local Area Network (VLAN) can be implemented on the Industrial Switch to logically create different broadcast

domain.

When the 802.1Q VLAN function is enabled, all ports on the switch belong to default VLAN of VID 1, which means they

logically are regarded as members of the same broadcast domain. The valid VLAN ID is in the range of number between 1

and 4094. The amount of VLAN groups is up to 256 including default VLAN that cannot be deleted.

Each member port of 802.1Q is on either an Access Link (no VLA N-tagged) or a T runk Link (VLAN-tagged). All frames

on an Access Link carry no VLAN identification. Conversely, all frames on a Trunk Link are VLAN-tagged. Besides, there

is the third mode—Hybrid. A Hybrid Link can carry both VLAN-tagged frames and untagged frames. A single port is

supposed to belong to one VLAN group, except it is on a Trunk/Hybrid Link.

The technique of 802.1Q tagging inserts a 4-byte tag, including VLAN ID of the destination port—PVID, in the frame. With

the combination of Access/Trunk/Hybrid Links, the communication across switches also can make the packet sent through

tagged and untagged ports.

Ports with tagging enabled will put the VID number, priority and other VLAN information into the

header of all packets that flow into those ports. If a packet has previously been tagged, the port

will not alter the packet, thus keeping the VLAN information intact. The VLAN information in the

tag can then be used by other 802.1Q compliant devices on the network to make

packet-forwarding decisions.

Ports with untagging enabled will strip the 802.1Q tag from all packets that flow into those

ports. If the packet doesn't have an 802.1Q VLAN tag, the port will not alter the packet. Thus,

all packets received by and forwarded by an untagging port will have no 802.1Q VLAN

information. (Remember that the PVID is only used internally within the Switch). Untagging is

used to send packets from an 802.1Q-compliant network device to a non-compliant network

device.

VLAN configuration information with other devices.

For example, having enabled GVRP on two switches, they are able to

automatically exchange the information of their VLAN database. Therefore, the

user doesn’t need to manually configure whether the link is trunk or hybrid, the

packets belonging to the same VLAN can communicate across switches. Tick

this checkbox to enable GVRP protocol. This checkbox is available while the

VLAN Operation Mode is in 802.1Q mode. Only when the VLAN members, whose Untagged VID (PVID) equals to the value

in this column, will have the permission to access the switch. The default value is

‘0’ that means this limit is not enabled (all members in different VLANs can

access this switch).

There are 3 types of link type.

Access Link:

A segment which provides the link path for one or more stations to the

VLAN-aware device. An Access Port (untagged port), connected to the access

link, has an untagged VID (also called PVID). After an untagged frame gets

into the access port, the switch will insert a four-byte tag in the frame. The

contents of the last 12-bit of the tag is untagged VID. When this frame is sent

out through any of the access port of the same PVID, the switch will remove

the tag from the frame to recover it to what it was. Those ports of the same

untagged VID are regarded as the same VLAN group members.

Trunk Link:

A segment which provides the link path for one or more VLAN-aware devices

(switches). A Trunk Port, connected to the trunk link, has an understanding of

tagged frame, which is used for the communication among VLANs across

switches. Which frames of the specified VIDs will be forwarded depends on the

values filled in the Tagged VID column field. Please insert a comma between

two VIDs.

Hybrid Link:

A segment which consists of Access and Trunk links. The hybrid port has both

the features of access and trunk ports. A hybrid port has a PVID belonging to a

particular VLAN, and it also forwards the specified tagged-frames for the

purpose of VLAN communication across switches.

5.6.2 Rapid Spanning Tree

The Rapid Spanning Tree Protocol (RSTP) is an evolution of the Spanning Tree Protocol and provides for faster

spanning tree convergence after a topology change. The system also supports STP and the system will auto-detect the

connected device that is running STP or RSTP protocol.

5.6.2.1 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

User’s Manual of ISW-1022M Series and ISW-1033MT

 The path cost to the root from the transmitting port

 The port identifier of the transmitting port

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

User’s Manual of ISW-1022M Series and ISW-1033MT

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

Switch

Figure 5-38 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.

5.6.2.2 RSTP Parameters

RSTP 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 RSTP operates in much the same way for both levels.

On the switch level, RSTP calculates the Bridge Identifier for each switch and then sets the Root

Bridge and the Designated Bridges.

On the port level, RSTP sets the Root Port and the Designated Ports.

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 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.

5.6 2.3 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

the default to ensure that the link between switch B and switch C is the blocked link.

5.6.2.5 Port Configuration

This web page provides the port configuration interface for RSTP. You can assign higher or lower priority to each port.

Rapid spanning tree will have the port with the higher priority in forwarding state and block other ports to make certain that

there is no loop in the LAN.

number between 0 and 240. The value of priority must be the multiple of 16.

Admin P2P:

User’s Manual of ISW-1022M Series and ISW-1033MT

The rapid state transitions possible within RSTP are dependent upon whether the

port concerned can only be connected to exactly another bridge (i.e. it is served

by a point-to-point LAN segment), or can be connected to two or more bridges

(i.e. it is served by a shared medium LAN segment). This function allows the P2P

status of the link to be manipulated administratively. True means the port is

regarded as a point-to-point link. False means the port is regarded as a shared

link. Auto means the link type is determined by the auto-negotiation between the

two peers.

Admin Edge:

Admin Non STP:

Path cost “0” is used to indicate auto-configuration mode. When the short path cost method is selected

and the default path cost recommended by the IEEE 8021w standard exceeds 65,535, the default is set

to 65,535.

By default, the system automatically detects the speed and duplex mode used on each port, and configures the path cost

according to the values shown below.

The port directly connected to end stations won’t create bridging loop in the

network. To configure the port as an edge port, set the port to “True” status.

The port includes the STP mathematic calculation. True is not including STP mathematic calculation. False is including the STP mathematic calculation.

Simple Network Management Protocol (SNMP) is the protocol developed to manage nodes (servers, workstations,

routers, switches and hubs etc.) on an IP network. SNMP enables network administrators to manage network

performance, find and solve network problems, and plan for network growth. Network management systems learn of

problems by receiving traps or change notices from network devices implementing SNMP.
