EDS-408A/405A Series User’s Manual Introduction

Inside the Future of Industrial Ethernet Technology

The trend in industrial communications and automation applications

As the world’s network and information technology becomes more mature, the trend is to use Ethernet as the major communications interface in many industrial communications, and automation applications. In fact, a whole new industry has sprung up to provide Ethernet products that comply with the requirements of demanding industrial applications.

Industrial vs. Commercial

Users have found that when moving Ethernet equipment from the comfortable office environment to the harsh and less predictable industrial environment, the commercial Ethernet equipment available in today’s market simply cannot meet the high reliability requirements demanded by industrial applications. This means that a more robust type of network equipment, commonly referred to as industrial Ethernet equipment, is required for these applications.

Informative vs. Passive

Since industrial Ethernet devices are often located at the endpoints of a system, such devices cannot always know what’s happening elsewhere on the network. This means that industrial Ethernet communication equipment that connects these devices must take responsibility for providing system maintainers with real-time alarm messages.

MOXA EtherDevice™ Switch

MOXA EtherDevice Switches come with a suite of useful maintenance and monitoring functions, and is designed to provide smooth and reliable operation in harsh industrial environments. You will find that MOXA EtherDevice Switches establish a new industrial Ethernet benchmark. The switches excellent for keeping automation systems running continuously, are ideal for sending status reports to help prevent system damages and losses, are a great tool for mastering your industrial Ethernet networks, and are well-suited for use with industrial device control networks.

ATTENTION

Throughout this User’s Manual, we use EDS as an abbreviation for MOXA EtherDevice Switch:

Chapter 2 Getting Started

This chapter explains how to access your MOXA EtherDevice Switch for the first time. There are three ways to access the switch: serial console, Telnet console, and web browser. The serial console connection method, which requires using a short serial cable to connect the switch to a PC’s COM port, can be used if you do not know the switch’s IP address. The Telnet console and web browser connection methods can be used to access MOXA EtherDevice Switches over an Ethernet LAN, or over the Internet.

The following topics are covered:

 RS-232 Console Configuration (115200, None, 8, 1, VT100)  Configuration Using a Telnet Console  Configuration Using a Web Browser  Disabling Telnet and Browser Access

Configuration Using a Telnet Console

You may use Telnet to access the EDS’s console utility over a network. To be able to access the EDS’s functions over the network (using Telnet or a Web Browser) from a PC host that is connected to the same LAN as the EDS, you need to make sure that the PC host and the EDS are on the same logical sub network. To do this, check your PC host’s IP address and netmask. By default, the EDS’s IP address is 192.168.127.253 and the EDS’s netmask is 255.255.0.0 (for a Class B network). If you do not change these values, and your PC host’s netmask is 255.255.0.0, then its IP address must have the form 192.168.xxx.xxx. On the other hand, if your PC host’s netmask is 255.255.255.0, then its IP address must have the form 192.168.127.xxx.

NOTE

To use the EDS’s management and monitoring functions from a PC host connected to the same LAN as the EDS, you must make sure that the PC host and the EDS are on the same logical sub network.

Before accessing the console utility via Telnet, first connect one of the ED’s RJ45 Ethernet ports to your Ethernet LAN, or directly to your PC’s Ethernet NIC. You can establish a connection with either a straight-through or cross-over Ethernet cable. If you have difficulty connecting, refer to the Auto MDI/MDI-X Connection section from the Hardware installation Guide for more information about the different types of Ethernet cables and ports.

The EDS’s default IP is 192.168.127.253.

Perform the following steps to access the console utility via Telnet.

1. Telnet to the EDS’s IP address from the Windows Run window (or fr om the command

prompt).

2. Type 1 to choose ansi/vt100, and then press Enter.

2-5

NOTE

The proprietary “Turbo Ring” protocol (recovery time < 300 ms) was developed by MOXA in 2003 to provide better network reliability and faster recovery time for redundant ring topologies. The “Turbo Ring V2” protocol (recovery time < 20 ms), which was released in 2007, supports additional redundant ring architectures.

In this manual, we use the terminology “Turbo Ring” ring and “Turbo Ring V2” ring to differentiate between rings configured for one or the other of these protocols.

For a detailed description of “Turbo Ring” and “Turbo Ring V2,” please refer to the Using Communication Redundancy section later in this chapter.

NOTE

If you upgrade the firmware of your EDS from Turbo Ring to Turbo Ring V2, bu t do not reset the switch to factory defaults, the DIP switches will be set to configure the EDS for a “Turbo Ring” ring. If you reset the switch to factory defaults, the DIP switches will be set to configure the EDS for a “Turbo Ring V2” ring.

How to Configure the Turbo Ring DIP Switches

The Turbo Ring DIP Switches are set to the OFF position at the factory.

NOTE

The four DIP Switches are used to configure both the “Turbo Ring” and “Turbo Ring V2” protocols, depending on which protocol is active. To select which protocol the EDS will use, start the user interface software, and then use the left menu to navigate to the Communication Redundancy page. To use one of the Turbo Ring protocols for the EDS, select either “Turbo Ring” or “Turbo Ring V2” in the Redundancy Protocol drop-down box. See the Configuring “Turbo Ring” and “Turbo Ring V2” section in this chapter for details.

The following tables show how to use the DIP switches to configure the EDS for “Turbo Ring” or “Turbo Ring V2.”

DIP switch 4 must be set to the ON position to enable DIP switches 1, 2, and 3. If DIP switch 4 is set to the “OFF” position, then DIP switches 1, 2, and 3 will all be disabled.

Configuring SNMP

EDS switches support SNMP protocol. The available versions are SNMP V1, SNMP V2c, and SNMP V3. SNMP V1 and SNMP V2c use a community string match for authentication, which means SNMP servers access all objects with read-only or read/write permissions using the community string public/private (default value). SNMP V3, which requires you to select an authentication level of MD5 or SHA, is the most secure protocol. You can also enable data encryption to enhance data security.

SNMP security modes and security levels supported by the EDS are shown in the following table. Select the security mode and level that will be used to communicate between the SNMP agent and manager.

Using Communication Redundancy

Setting up Communication Redundancy on your network helps protect critical links again st failure, protects against network loops, and keeps network downtime at a minimum.

The Communication Redundancy function allows the user to set up redundant loops in the network to provide a backup data transmission route in the event that a cable is inadvertently disconnected or damaged. This feature is particularly important for industrial applications, since it could take several minutes to locate the disconnected or severed cable. For example, if the EDS is used as a key communications component of a production line, several minutes of downtime could result in a big loss in production and revenue. The EDS supports three different protocols to support this communication redundancy function—Rapid Spanning Tree/ Spanning Tree Protocol (IEEE 802.1W/1D), Turbo Ring, and Turbo Ring V2.

When configuring a redundant ring, all switche s on the same ring must be configured to use the same redundancy protocol. You cannot mix the “Turbo Ring,” “Turbo Ring V2,” and STP/RSTP protocols on the same ring. The following table lists the key differences between each feature. Use this information to evaluate the benefits of each, and then determine which features are most suitable for your network.

Turbo Ring V2 Turbo Ring STP RSTP Topology Ring Ring Ring, Mesh Ring, Mesh Recovery Time < 20 ms < 300 ms Up to 30 sec. Up to 5 sec

NOTE

Most of MOXA’s managed switches now support two proprietary Turbo Ring protocols:

(1) “Turbo Ring” refers to the original version of MOXA’s proprietary redundant ring

protocol, which has a recovery time of under 300 ms.

(2) “Turbo Ring V2” refers to the new generation Turbo Ring, which has a recovery time

of under 20 ms.

In this manual, we use the terminology “Turbo Ring” ring and “Turbo Ring V2” ring to differentiate between rings configured for one or the other of these protocols.

The Turbo Ring Concept

MOXA developed the proprietary Turbo Ring protocol to optimize communication redundancy and achieve a faster recovery time on the network.

The Turbo Ring and Turbo Ring V2 protocols identify one switch as the master of the network, and then automatically block packets from traveling through any of the network’s redundant loops.

3-18

EDS-408A/405A Series User’s Manual Featured Functions

In the event that one branch of the ring gets disconnected from the rest of the network, the protocol automatically readjusts the ring so that the part of the network that was disconnected can reestablish contact with the rest of the network.

Initial setup of a “Turbo Ring” or “Turbo Ring V2” ring

1. For each switch in the ring, select any two

ports as the redundant ports.

2. Connect redundant ports on neighboring

switches to form the redundant ring.

The user does not need to configure any of the switches as the master to use Turbo Ring or Turbo Ring V2. If none of the switches in the ring is configured as the master, then the protocol will automatically assign master status to one of the switches. In fact, the master is only used to identify which segment in the redundant ring acts as the backup path. In the following subsections, we explain how the redundant path is selected for ring s configured for Turbo Ring, and Turbo Ring V2.

Determining the Redundant Path of a “Turbo Ring” Ring

In this case, the redundant segment (i.e., the segment that will be blocked during normal operation) is determined by the number of EDS units that make up the ring, and where the ring master is located.

“Turbo Ring” rings with an even number of EDS units

Master

If there are 2N EDS units (an even number) in the “Turbo Ring” ring, then the backup segment is one of the two segments connected to the (N+1)st EDS (i.e., the EDS unit directly opposite the master).

3-19

EDS-408A/405A Series User’s Manual Featured Functions

“Turbo Ring” rings with an odd number of EDS units

Master

If there are 2N+1 EDS units (an odd number) in the “Turbo Ring” ring, with EDS units and segments labeled counterclockwise, then segment N+1 will serve as the backup path.

For the example shown here, N=1, so that N+1=2.

Segment N+1

Determining the Redundant Path of a “Turbo Ring V2” Ring

Master

For a “Turbo Ring V2” ring, the backup segment is the segment connected to the 2nd redundant port on the master.

See Configuring “Turbo Ring V2” in the

Configuring “Turbo Ring” and “Turbo Ring V2” section below.

Ring Coupling Configuration

For some systems, it may not be convenient to connect all devices in the system to create one BIG redundant ring, since some devices could be located in a remote area. For these systems, “Ring Coupling” can be used to separate the devices into different smaller redundant rings, but in such a way that they can still communicate with each other.

ATTENTION

In a VLAN environment, the user must set “Redundant Port,” “Coupling Port,” and “Coupling Control Port” to join all VLANs, since these ports act as the “backbone” to transmit all packets of different VLANs to different EDS units.

To configure the Ring Coupling function for a “Turbo Ring” ring, select tw o EDS units (e.g., Switch A and B in the above figure) in the ring, and another two EDS units in the adjacent ring (e.g., Switch C and D).

Decide which two ports in each switch are appropriate to be used as coupling ports, and then link them together. Next, assign one switch (e.g., Switch A) to be the “coupler,” and connect the coupler’s coupling control port with Switch B (for this example).

The coupler switch (i.e., Switch A) will monitor switch B through the coupling control port to determine whether or not the coupling port’s backup path should be recovered.

Note that the ring coupling settings for a “Turbo Ring V2” ring are different from a “Turbo Ring” ring. For Turbo Ring V2, Ring Coupling is enabled by configuring the “Coupling Port (Primary)” on Switch B, and the “Coupling Port (Backup)” on Switch A only. You do not need to set u p a coupling control port, so that a “Turbo Ring V2” ring does not use a coupling control line.

The “Coupling Port (Backup)” on Switch A is used for the backup path, and connects directly to an extra network port on Switch C. The “Coupling Port (Primary)” on Switch B monitors the status of the main path, and connects directly to an extra network port on Switch D. With ring coupling established, Switch A can activate the backup path as soon as it detects a problem with the main path.

EDS-408A/405A Series User’s Manual Featured Functions

ATTENTION

Ring Coupling only needs to be enabled on one of the switches serving as the Ring Coupler. The Coupler must designate different ports as the two Turbo Ring ports and the coupling port.

NOTE

You do not need to use the same EDS unit for both Ring Coupling and Ring Master.

Dual-Ring Configuration (applies only to “Turbo Ring V2”)

The STP/RSTP Concept

Spanning Tree Protocol (STP) was designed to help reduce link failures in a network, and provide protection from loops. Networks that have a complicated architecture are prone to broadcast storms caused by unintended loops in the network. MOXA EtherDevice Switch’s STP feature is disabled by default. To be completely effective, you must enable RSTP/STP on every EDS connected to your network.

Rapid Spanning Tree Protocol (RSTP) implements the Spanning Tree Algorithm and Protocol defined by IEEE Std 802.1w-2001. RSTP provides the following benefits:

3-27

EDS-408A/405A Series User’s Manual Featured Functions

y The topology of a bridged network will be determined much more quickly compared to STP. y RSTP is backward compatible with STP, making it relatively easy to deploy. For example:

¾ Defaults to sending 802.1D style BPDUs if packets with this format are received. ¾ STP (802.1D) and RSTP (802.1w) can operate on different ports of the same EDS. This

feature is particularly helpful when EDS ports are connected to older equipment, such as legacy switches.

RSTP provides essentially the same functionality as STP. To see how the two systems differ, see the Differences between RSTP and STP section in this chapter.

NOTE

What is STP?

The STP protocol is part of the IEEE Std 802.1D, 1998 Edition bridge specification. The following explanation uses bridge instead of switch.

STP (802.1D) is a bridge-based system that is used to implement parallel paths for network traffic. STP uses a loop-detection process to:

y Locate and then disable less efficient paths (i.e., paths that have a lower bandwidth). y Enable one of the less efficient paths if the most efficient path fails.

The figure below shows a network made up of three LANs separated by three bridges. Each segment uses at most two paths to communicate with the other segments. Since this configuration can give rise to loops, the network will overload if STP is NOT enabled.

LAN 1

Bridge B

Bridge A

LAN 2

Bridge C

LAN 3

If STP is enabled, it will detect duplicate paths and prevent, or block, one of them from forwarding traffic. In the following example, STP determines that traffic from LAN segment 2 to LAN segment 1 should flow through Bridges C and A as this path has a greater bandwidth and is therefore more efficient.

3-28

EDS-408A/405A Series User’s Manual Featured Functions

LAN 1

Bridge B

Bridge A

What happens if a link failure is detected? As shown in next figure, the STP process reconfigures the network so that traffic from LAN segment 2 flows through Bridge B.

Bridge A

STP determines which path between each bridged segment is most efficient, and then assigns a specific reference point on the network. When the most efficient path has been identified, the other paths are blocked. In the previous 3 figures, STP first determined that the path through Bridge C was the most efficient, and as a result, blocked the path through Bridge B. After the failure of Bridge C, STP re-evaluated the situation and opened the path through Bridge B.

How STP Works

When enabled, STP determines the most appropriate path for traffic through a network. The way it does this is outlined in the following sections.

STP Requirements

Before STP can configure the network, the system must satisfy the following requirements: y Communication between all the bridges. This communication is carried out using Bridge

Protocol Data Units (BPDUs), which are transmitted in packets with a known multicast address.

y Each bridge must have a Bridge Identifier that specifies which bridge acts as the central

reference point, or Root Bridge, for the STP system—bridges with a lower Bridge Identifier are more likely to be designated as the Root Bridge. The Bridge Identifier is calculated using the MAC address of the bridge and a priority defined for the bridge. The default priority of EDS is 32768.

y Each port has a cost that specifies the efficiency of each link. The efficieny cost is usually

determined by the bandwidth of the link, with less efficient links assigned a higher cost. The following table shows the default port costs for a switch:

STP Calculation

The first step of the STP process is to perform calculations. During this stage, each bridge on the network transmits BPDUs. The following items will be calculated:

y The bridge that should be the Root Bridge. The Root Bridge is the central reference point

from which the network is configured.

y The Root Path Costs for each bridge. This is the cost of the paths from each bridge to the Root

Bridge.

y The identity of each bridge’s Root Port. The Root Port is the port on the bridge that connects

to the Root Bridge via the most efficient path; in other words, the port connected to the Root Bridge via the path with the lowest Root Path Cost. The Root Bridge, however, does not have a Root Port.

y The identity of the Designated Bridge for each LAN segment. Th e Designated Bridge is the

bridge with the lowest Root Path Cost from that segment. If several bridges have the same Root Path Cost, the one with the lowest Bridge Identifier becomes the Designated Bridge. Traffic transmitted in the direction of the Root Bridge will flow through the Designated Bridge. The port on this bridge that connects to the segment is called the Designated Bridge Port.

STP Configuration

After all the bridges on the network agree on the identity of the Root Bridge, and all other relevant parameters have been established, each bridge is configured to forward traffic only between its Root Port and the Designated Bridge Ports for the respective network segments. All other ports are blocked, which means that they will not be allowed to receive or forward traffic.

Path Cost

802.1w-2001

STP Reconfiguration

Once the network topology has stabilized, each bridge listens for Hello BPDUs transmitted from the Root Bridge at regular intervals. If a bridge does not receive a Hello BPDU after a certain interval (the Max Age time), the bridge assumes that the Root Bridge, or a link between itself and the Root Bridge, has gone down. This will trigger the bridge to reconfigure the network to account for the change. If you have configured an SNMP trap destination, when the topology of your network changes, the first bridge to detect the change sends out an SNMP trap.

Differences between RSTP and STP

RSTP is similar to STP, but includes additional information in the BPDUs that allow each bridge to confirm that it has taken action to prevent loops from forming when it decides to enable a link to a neighboring bridge. Adjacent bridges connected via point-to-point links will be able to enable a link without waiting to ensure that all other bridges in the network have had time to react to the change. The main benefit of RSTP is that the configuration decision is made locally rather than network-wide, allowing RSTP to carry out automatic configuration and restore a link faster than STP.

STP Example

The LAN shown below has three segments, with adjacent segments connected using two possible links. The various STP factors, such as Cost, Root Port, Designated Bridge Port, and Blocked Port are shown in the figure.

Port 2 (Blocked Port)

y Bridge A has been selected as the Root Bridge, since it was determined to have the lowest

Bridge Identifier on the network.

y Since Bridge A is the Root Bridge, it is also the Designated Bridge for LAN segment 1. Port 1

on Bridge A is selected as the Designated Bridge Port for LAN Segment 1.

y Ports 1 of Bridges B, C, X, and Y are all Root Ports since they are nearest to the Root Bridge,

and therefore have the most efficient path.

y Bridges B and X offer the same Root Path Cost for LAN segment 2. However, Bridge B was

selected as the Designated Bridge for that segment since it has a lower Bridge Identifier. Port 2 on Bridge B is selected as the Designated Bridge Port fo r LAN Segment 2.

y Bridge C is the Designated Bridge for LAN segment 3, because it has the lowest Root Path

Cost for LAN Segment 3:

¾ The route through Bridges C and B costs 200 (C to B=100, B to A=100) ¾ The route through Bridges Y and B costs 300 (Y to B=200, B to A=100)

y The Designated Bridge Port for LAN Segment 3 is Port 2 on Bridge C.

Using STP on a Network with Multiple VLANs

IEEE Std 802.1D, 1998 Edition, does not take into account VLANs when calculating STP information—the calculations depend only on the physical connections. Consequently, some network configurations will result in VLANs being subdivided into a number of isolated sections by the STP system. You must ensure that every VLAN configuration on your network takes into account the expected STP topology and alternative topologies that may result from link failures. The following figure shows an example of a network that co ntains VLANs 1 and 2. The VLANs are connected using the 802.1Q-tagged link between Switch B and Switch C. By default, this link

3-31

EDS-408A/405A Series User’s Manual Featured Functions

has a port cost of 100 and is automatically blocked because the other Switch-to-Switch connections have a port cost of 36 (18+18). This m eans that both VLANs are now subdivided—VLAN 1 on Switch units A and B cannot communicate with VLAN 1 on Switch C, and VLAN 2 on Switch units A and C cannot communicate with VLAN 2 on Switch B.

Switch A

100BaseTX full-duplex Link; only carries VLAN1 (path cost = 18)

To avoid subdividing VLANs, all inter-switch connections should be made members of all available 802.1Q VLANs. This will ensure connectivity at all times. For example, the connections between Switches A and B, and between Switches A and C should be 802.1Q tagged and carrying VLANs 1 and 2 to ensure connectivity.

[Eq. 4]: 2 * (Hello Time + 1 sec) ≦ Max. Age ≦ 2 * (Forwarding Delay – 1 sec) The EDS’s firmware will alert you immediately if any of these restrictions are violated. For

example, setting Hello Time = 5 sec, Max. Age = 20 sec, and Forwarding Delay = 4 sec does not violate Eqs. 1

through 3, but does violate Eq. 4, since in this case, 2 * (Hello Time + 1 sec) = 12 sec, and 2 * (Forwarding Delay – 1 sec) = 6 sec. You can remedy the situation in a multitude of ways. One solution is simply to increase the

Forwarding Delay to at least 11 sec. HINT: Take the following steps to avoid guessing:

Step 1: Assign a value to Hello Time and then calculate the left most part of Eq. 4 to get the lower limit of Max. Age.

Step 2: Assign a value to Forwarding Delay and then calculate the right most part of Eq. 4 to get the upper limit for Max. Age.

Step 3: Assign a value to Forwarding Delay that satisfies the conditions in Eq. 3 and Eq. 4.

Using Traffic Prioritization

EThe DS’s traffic prioritization capability provides Quality of Service (QoS) to your network by making data delivery more reliable. You can prioritize traffic on your network to ensure that high priority data is transmitted with minimum delay. Traffic can be controlled by a set of rules to obtain the required Quality of Service for your network. The rules define different types of traffic and specify how each type should be treated as it passes through the switch. The EDS can inspect both IEEE 802.1p/1Q layer 2 QoS tags, and even layer 3 TOS information to provide consistent classification of the entire network. The EDS’s QoS capability improves the performance and determinism of industrial networks for mission critical applications.

The Traffic Prioritization Concept

What is Traffic Prioritization?

Traffic prioritization allows you to prioritize data so that time-sensitive and system-critical data can be transferred smoothly and with minimal delay over a network. The benefits of using traffic prioritization are:

y Improve network performance by controlling a wide variety of traffic and managing

congestion.

y Assign priorities to different categories of traffic. For example, set higher priorities for

time-critical or business-critical applications.

y Provide pred ictable throughput for multimedia applications, such as video conferencing or

voice over IP, and minimize traffic delay and jitter.

y Improve network performance as the amount of traffic grows. This will save cost by reducing

the need to keep adding bandwidth to the network.

How Traffic Prioritization Works

Traffic prioritization uses the four traffic queues that are present in your EDS to ensure that high priority traffic is forwarded on a different queue from lower priority traffic. This is what provides Quality of Service (QoS) to your network.

The EDS traffic prioritization depends on two industry-standard methods:

3-35

EDS-408A/405A Series User’s Manual Featured Functions

y IEEE 802.1D—a layer 2 marking scheme. y Differentiated Services (DiffServ)—a layer 3 marking scheme.

IEEE 802.1D Traffic Marking

The IEEE Std 802.1D, 1998 Edition marking scheme, which is an enhancement to IEEE Std

802.1D, enables Quality of Service on the LAN. Traffic service levels are defined in the IEEE

802.1Q 4-byte tag, which is used to carry VLAN identification as well as IEEE 802.1p priority information. The 4-byte tag immediately follows the destination MAC address an d Source MAC address.

The IEEE Std 802.1D, 1998 Edition priority marking scheme assigns an IEEE 802.1p priority level between 0 and 7 to each frame. This determines the level of service that type of traffic should receive. Refer to the table below for an example of how different traffic types can be mapped to the eight IEEE 802.1p priority levels.

IEEE 802.1p Priority Level IEEE 802.1D Traffic Type

0 Best Effort (default) 1 Background 2 Standard (spare) 3 Excellent Effort (business critical) 4 Controlled Load (streami ng m ult imedia) 5 Video (interactive media); less than 100 milliseconds

of latency and jitter

6 Voice (interactive voice); less than 10 milliseconds of

latency and jitter

7 Network Control Reserved traffic

Even though the IEEE 802.1D standard is the most widely used prioritization scheme in the LAN environment, it still has some restrictions:

y It requires an additional 4-byte tag in the frame, which is normally optional in Ethernet

networks. Without this tag, the scheme cannot work.

y The tag is part of the IEEE 802.1Q header, so to implement QoS at layer 2, the entire network

must implement IEEE 802.1Q VLAN tagging.

It is only supported on a LAN and not across routed WAN links, since the IEEE 802.1Q tags are removed when the packets pass through a router.

Differentiated Services (DiffServ) Traffic Marking

DiffServ is a Layer 3 marking scheme that uses the DiffServ Code Point (DSCP) field in the IP header to store the packet priority information. DSCP is an advanced intelligent method of traffic marking because you can choose how your network prioritizes different types of traffic. DSCP uses 64 values that map to user-defined service levels, allowing you to establish more control over network traffic.

Advantages of DiffServ over IEEE 802.1D are: y Configure how you want your switch to treat selected applications and types of traffic by

assigning various grades of network service to them.

y No extra tags are required in the packet. y DSCP uses the IP header of a packet and therefore priority is preserved across the Internet. y DSCP is backward compatible with IPV4 TOS, which allows operation with existing devices

that use a layer 3 TOS enabled prioritization scheme.

Traffic Prioritization

The EDS classifies traffic based on layer 2 of the OSI 7 layer model, and the switch prioritizes received traffic according to the priority information defined in the received packet. Incoming

3-36

EDS-408A/405A Series User’s Manual Featured Functions

traffic is classified based upon the IEEE 802.1D frame and is assigned to the appropriate priority queue based on the IEEE 802.1p service level value defined in that packet. Service level markings (values) are defined in the IEEE 802.1Q 4-byte tag, and consequently traffic will only contain

802.1p priority markings if the network is configured with VLANs and VLAN tagging. The traffic flow through the switch is as follows:

1. A packet received by the EDS may or may not have an 802.1p tag associated with it. If it does

not, then it is given a default 802.1p tag (which is usually 0). Alternatively, the packet may be marked with a new 802.1p value, which will result in all knowledge of the old 802.1p tag being lost.

2. Because the 802.1p priority levels are fixed to the traffic queues, the packet will be placed in

the appropriate priority queue, ready for transmission through the appropriate egress port. When the packet reaches the head of its queue and is about to be transmitted, the device determines whether or not the egress port is tagged for that VLAN. If it is, then the new

802.1p tag is used in the extended 802.1D header.

The EDS will check a packet received at the ingress port for IEEE 802.1D traffic classification, and then prioritize it based upon the IEEE 802.1p value (service levels) in that tag. It is this 802.1p value that determines which traffic queue the packet is mapped to.

Traffic Queues

The EDS hardware has multiple traffic queues that allow packet prioritization to occur. Higher priority traffic can pass through the EDS without being delayed by lower priority traffic. As each packet arrives in the EDS, it passes through any ingress processing (which includes classification, marking/re-marking), and is then sorted into the appropriate queue. The switch then forwards packets from each queue.

The EDS supports two different queuing mechanisms: y Weight Fair: This method services all the traffic queues, giving priority to the higher priority

queues. Under most circumstances, this method gives high priority precedence over low-priority, but in the event that high-priority traffic exceeds the link capacity, lower priority traffic is not blocked.

y Strict: This method services high traffic queues first; low priority queues are delayed until no

more high priority data needs to be sent. This method always gives precedence to high priority over low-priority.

to the four priorities. This approach prevents the lower priority frames from being starved of opportunity for transmission with only a slight delay to the higher priority frames.

In the Strict-priority scheme, all top-priority frames egress a port until that priority’s queue is empty, and then the next lower priority queue’s frames egress. This approach can cause the lower priorities to be starved of opportunity for transmitting any frames but ensures all high priority frames to egress the switch as soon as possible.

Using Virtual LANs

Setting up Virtual LANs (VLANs) on your EDS increases the efficiency of your network by dividing the LAN into logical segments, as opposed to physical segments. In general, VLANs are easier to manage.

The Virtual LAN (VLAN) Concept

What is a VLAN?

A VLAN is a group of devices that can be located anywhere on a network, but which communicate as if they are on the same physical segment. With VLANs, you can segment your network without being restricted by physical connections—a limitation of traditional network design. As an example, with VLANs you can segment your network according to:

y Departmental groups—You could have one VLAN for the Marketing department, another

for the Finance department, and another for the Development department.

y Hierarchical groups—You could have one VLAN for directors, another for managers, and

another for general staff.

y Usage groups—You could have one VLAN for e-mail users, and another for multimedia

users.

Benefits of VLANs

The main benefit of VLANs is that they provide a network segmentation system that is far more flexible than traditional networks. Using VLANs also provides you with three other benefits:

y VLANs ease the relocation of devices on networks: With traditional networks, network

administrators spend much of their time dealing with moves and changes. If users move to a different subnetwork, the addresses of each host must be updated manually. With a VLAN setup, if a host on VLAN Marketing, for example, is moved to a port in another part of the network, and retains its original subnet membership, you only need to specify that the new port is on VLAN Marketing. You do not need to do any re- cabl i ng .

y VLANs provide extra security: Devices within each VLAN can only communicate with

other devices on the same VLAN. If a device on VLAN Marketing needs to communicate with devices on VLAN Finance, the traffic must pass through a routing device or Layer 3 switch.

y VLANs help control traffic: With traditional networks, congestion can be caused by

broadcast traffic that is directed to all network devices, regardless of whether or not they need it. VLANs increase the efficiency of your network because each VL AN can be set up to contain only those devices that need to communicate with each other.

Using Virtual LANs

Port-based VLANs and the MOXA EtherDevice Switch

The EDS-408A/405A supports Port-based VLAN. When using this function, you must first define which ports should join the VLAN. Once set, devices can be moved around the network without affecting to which VLAN the device is connected.

For example, to separate port 2 and port 3 to different groups due to security issues, click VLAN Settings and then select Port-Based VLAN. For this example, place port 2 on VLAN 1 and port 3 on VLAN 2. Ports 2 and 3 will not be able to communicate with each other, even though they are on the same switch.

3-41

EDS-408A/405A Series User’s Manual Featured Functions

NOTE

Port-based VLAN settings only affect one switch. The EDS-405A can have a maximum of 5 VLAN settings and the EDS-408A can have a maximum of 8 VLAN settings.

The Turbo Ring Ports and Coupler Ports will be added to all VLANs if you enable the “Turbo Ring DIP Switch” and set the Turbo Ring DIP Switch from OFF to ON.

If you enable the Hardware DIP Switch for Turbo Ring and set the Turbo Ring DIP Switch from ON to OFF, then the Ring Ports and Coupler Ports that are added to all VLANs will be restored to their previous software settings. (For details on how to do this, refer to “Configuring Basic Settings—Turbo Ring DIP Switch.”)

Using Auto Warning

Since industrial Ethernet devices are often located at remote areas of a system, these devices will not always know what is happening elsewhere on the network. This means that an industrial Ethernet switch that connects to these devices must provide system maintainers with real-time warning messages. Even when control engineers are out of the control room for an extended period of time, they can still be informed of the status of devices almost instantaneously when exceptions occur. The EDS supports different approaches such as email and relay output to warn engineers automatically.

Configuring Email Warning

The Auto Email Warning function uses e-mail to alert the user when certain user-configured events take place.

Three basic steps are required to set up the Auto Warning function:

1. Configuring Email Event Types

Select the desired Event types from the Console or Web Browser Event type page (a description of each event type is given later in the Email Warning Events setting subsection).

Using Line-Swap-Fast-Recovery

The Line-Swap Fast Recovery function, which is enabled by default, allows the EDS to return to normal operation very quickly after devices are un pl u g ged and the n re- plugged into different ports. The recovery time is in the order of a few milliseconds. Compare this with standard commercial switches for which the recovery time could be in the order of several minutes. To disable the Line-Swap Fast Recovery function, or to re-enable the function after it has already been disabled, access either the Console utility’s Line-Swap recovery page, or the Web Browser interface’s Line-Swap fast recovery page, as shown next.

Using Set Device IP

To reduce the effort required to set up IP addresses, the EDS-408A/405A series comes equipped with DHCP/BootP server and RARP protocol to set up IP addresses of Ethernet-enabled devices automatically.

When enabled, the Set device IP function allows th e EDS to assign specific IP addresses automatically to connected devices that are equipped with DHCP Client or RARP protocol. In effect, the EDS acts as a DHCP server by assigning a connected device with a specific IP address stored in the EDS’s internal memory. Each time the connected device is switched on or rebooted, the EDS sends the device the desired IP address.

Take the following steps to use the Set device IP function: STEP 1—set up the connected devices

Set up the Ethernet-enabled devices connected to the EDS for which you would like IP addresses to be assigned automatically. The devices must be configured to obtain their IP address automatically.

The devices’ configuration utility should include a setup page that allows you to choose an option similar to Obtain an IP address automatically.

For example, Windows’ TCP/IP Properties window is shown at the right. Although your device’s configuration utility may look quite a bit different, this figure should give you some idea of what to look for.

You also need to decide which of the EDS’s ports your Ethernet-enabled devices will be connected to. You will need to set up each of these ports separately, as described in the next step.

STEP 2 Configure the EDS’s Set device IP function, either from the Console utility or from the Web

Browser interface. In either case, you simply need to enter the Desired IP for each port that needs to be configured.

STEP 3 Be sure to activate your settings before exiting.

• When using the Web Browser interface, activate by clicking the Activate button.

• When using the Console utility, activate by first highlighting the Activate menu option, and

then press Enter. You should receive the Set device IP settings are now active! (Press any key to continue) message.

Using Diagnosis

The EDS provides two important tools for administrators to diagnose network systems.

Mirror Port

The Mirror port function can be used to monitor data being transmitted through a specific port. This is done by setting up another port (the mirror port) to receive the same data being transmitted from, or both to and from, the port under observation. This allows the network administrator to “sniff” the observed port and thus keep tabs on network activity.

3-51

EDS-408A/405A Series User’s Manual Featured Functions

Do the following to set up the Mirror Port function: STEP 1

Configure the EDS’s Mirror Port function from either the Console utility or Web Browser interface. You will need to configure three settings:

Ping

Monitored Port

Mirror Port

Watch Direction

STEP 2

Be sure to activate your settings before exiting.

• When using the Web Browser interface, activate by clicking the Activate button.

• When using the Console utility, activate by first highlighting the Activate menu option, and

then press Enter. You should receive the Mirror port settings are now active! (Press any key to continue) message.

Select the port number of the port whose network activity will be monitored.

Select the port number of the port that will be used to monitor the activity of the monitored port.

Select one of the following three watch direction options:

y Input data stream

Select this option to monitor only those data packets coming in through the EDS’s port.

y Output data stream

Select this option to monitor only those data packets being sent out through the EDS’s port.

y Bi-directional

Select this option to monitor data packets both coming into, and being sent out through, the EDS’s port.

The Ping function uses the ping command to give users a simple but powerful tool for troubleshooting network problems. The function’s most unique feature is that even though the ping command is entered from the user’s PC keyboard, the actual ping command originates from the EDS itself. In this way, the user can essentially control the EDS and send ping commands out through its ports.

To use the Ping function, type in the desired IP address, and then press Enter from the Console utility, or click Ping when using the Web Browser interface.

3-52

EDS-408A/405A Series User’s Manual Featured Functions

Using the Monitor

You can monitor statistics in real time from the EDS’s web console and serial console.

Monitor by Switch

Access the Monitor by selecting System from the left selection bar. Monitor by System allows the user to view a graph that shows the combined data transmission activity of all of the EDS’s ports. Click on one of the four options—Total Packets, TX Packets, RX Packets, or Error Packets—to view transmission activity of specific types of packets. Recall that TX Packets are packets sent out from the EDS, RX Packets are packets received from connected devices, and Error Packets are packets that did not pass TCP/IP’s error checking algorithm. The Total Packets option displays a graph that combines TX, RX, and Error Packet activity. The four graphs (Total Packets, TX Packets, RX Packets, and Error Packets) have the same form, so we show only the Total Packets graph here. The graph displays data transmission activity by showing Packets/s (i.e., packets per second, or pps) versus sec. (seconds). In fact, three curves are displayed on the same graph: Uni-cast packets (in red color), Multi-cast packets (in green color), and Broad-cast packets (in blue color). The graph is updated every few seconds, allowing the user to analyze data transmission activity in real-time.

Monitor by Port

Access the Monitor by Port function by selecting ALL 10/100M Ports or Porti, in which i= 1, 2, … 8, etc., from the left pull-down list. The Porti options are identical to the Monitor by System function discussed previously, in that users can view graphs that show Total Packets, TX Packets, RX Packets, or Error Packets activity, but in this case, only for an individual port. 10/100M Ports option is essentially a graphical display of the individual port activity that can be viewed with the Console Monitor function discussed above. The All 10/100M Ports option shows three vertical bars for each port. The height of the bar represents Packets/s for the type of packet, at the instant the bar is being viewed. That is, as time progresses, the height of the bar moves up or down so that the user can view the change in the rate of packet transmission. The red colored bar shows Uni-cast packets, the green colored bar shows Multi-cast packets, and the blue colored bar shows Broad-cast packets. The graph is updated every few seconds, allowing the user to analyze data transmission activity in real-time.
