1, VT100)

NOTE

• You cannot connect to the serial and Telnet console at the same time.

• You can connect to the web console and another console (serial or Telnet) at the same time. However, we strongly recommend that you do NOT do so. Following this advice will allow you to maintain better control over the Moxa switch’s configuration.

NOTE

We recommend using PComm Terminal Emulator when opening the serial console. This software can be downloaded free of charge from the Moxa website.

Before running PComm Terminal Emulator, use an RJ45 to DB9-F (or RJ45 to DB25-F) cable to connect the

Moxa switch’s console port to your PC’s COM port (generally COM1 or COM2, depending on how your system is set up).

After installing PComm Terminal Emulator, open the Moxa switch’s serial console as follows:

1. From the Windows desktop, click Start Programs PComm Lite 1.3 Terminal Emulator.

2. Select Open under the Port Manager menu to open a new connection.

3. The Property window should open. On the Communication Parameter tab for Ports, select the COM port that is being used for the console connection. Set the other fields as follows: 115200 for Baud Rate,

8 for Data Bits, None for Parity, and 1 for Stop Bits.

Accessible IP List

The Moxa switch uses an IP address-based filtering method to control access.

You may add or remove IP addresses to limit access to the Moxa switch. When the accessible IP list is enabled, only addresses on the list will be allowed access to the Moxa switch. Each IP address and netmask entry can be tailored for different situations:

Grant access to one host with a specific IP address

For example, enter IP address 192.168.1.1 with netmask 255.255.255.255 to allow access to 192.168.1.1 only.

Grant access to any host on a specific subnetwork

For example, enter IP address 192.168.1.0 with netmask 255.255.255.0 to allow access to all IPs on the subnet defined by this IP address/subnet mask combination.

Grant access to all hosts

Make sure the accessible IP list is not enabled. Remove the checkmark from Enable the accessible IP

list.

The following table shows additional configuration examples:

IEEE 1588 PTP

The following information is taken from the NIST website at http: //ieee1588.nist.gov/intro.htm:

“Time measurement can be accomplished using the IEEE Standard for a Precision Clock Synchronization

Protocol for Networked Measurement and Control Systems (IEEE 1588-2008) to synchronize real-time clocks incorporated within each component of the electrical power system for power automation applications.

IEEE 1588, which was published in November 2002, expands the performance capabilities of Ethernet networks to control systems that operate over a communication network. In recent years an increasing number of electrical power systems have been using a more distributed architecture with network technologies that have less stringent timing specifications. IEEE 1588 generates a master-slave relationship between the clocks, and enforces the specific timing requirements in such power systems. All devices ultimately get their time from a clock known as the grandmaster clock. In its basic form, the protocol is intended to be administration free.”

How does an Ethernet switch affect 1588 synchronization?

The following content is taken from the NIST website at http: //ieee1588.nist.gov/switch.htm:

“An Ethernet switch potentially introduces multi-microsecond fluctuations in the latency between the 1588 grandmaster clock and a 1588 slave clock. Uncorrected these fluctuations will cause synchronization errors.

The magnitude of these fluctuations depends on the design of the Ethernet switch and the details of the communication traffic. Experiments with prototype implementations of IEEE 1588 indicate that with suitable care the effect of these fluctuations can be successfully managed. For example, use of appropriate statistics in the 1588 devices to recognized significant fluctuations and use suitable averaging techniques in the algorithms controlling the correction of the local 1588 clock will be the good design means to achieve the highest time accuracy.”

3-10

Moxa Managed Ethernet Switches Featured Functions

Can Ethernet switches be designed to avoid the effects of these fluctuations?

A switch can be designed to support IEEE 1588 while avoiding the effects of queuing. In this case two modifications to the usual design of an Ethernet switch are necessary:

NOTE

1. The Boundary Clock and Transparent Clock functionalities defined by IEEE 1588 must be implemented in the switch.

2. The switch must be configured such that it does not pass IEEE 1588 message traffic using the normal communication mechanisms of the switch.

Such an Ethernet switch will synchronize clocks directly connected to one of its ports to the highest possible accuracy.

If the CM-600-4TX-PTP module is not installed, then the EDS-600 only supports software-based IEEE 1588.

Using Port Trunking

Link aggregation involves grouping links into a link aggregation group. A MAC client can treat link aggregation groups as if they were a single link.

The Moxa switch’s port trunking feature allows devices to communicate by aggregating up to 4 trunk groups, with a maximum of 8 ports for each group. If one of the 8 ports fails, the other seven ports will automatically provide backup and share the traffic.

Port trunking can be used to combine up to 8 ports between two Moxa switches. If all ports on both switches are configured as 100BaseTX and they are operating in full duplex, the potential bandwidth of the connection will be 1600 Mbps.

The Port Trunking Concept

Moxa has developed a port trunking protocol that provides the following benefits:

• Greater flexibility in setting up your network connections, since the bandwidth of a link can be doubled, tripled, or quadrupled.

• Redundancy—if one link is broken, the remaining trunked ports share the traffic within this trunk group.

• Load sharing—MAC client traffic can be distributed across multiple links.

To avoid broadcast storms or loops in your network while configuring a trunk, first disable or disconnect all ports that you want to add to the trunk or remove from the trunk. After you finish configuring the trunk, enable or re-connect the ports.

If all ports on both switch units are configured as 100BaseTX and they are operating in full duplex mode, the potential bandwidth of the connection will be up to 1.6 Gbps. This means that users can double, triple, or quadruple the bandwidth of the connection by port trunking between two Moxa switches.

Each Moxa switch can set a maximum of 4 port trunking groups. When you activate port trunking, certain settings on each port will be reset to factory default values or disabled:

• Communication redundancy will be reset

• 802.1Q VLAN will be reset

• Multicast Filtering will be reset

• Port Lock will be reset and disabled.

• Set Device IP will be reset

• Mirror will be reset

After port trunking has been activated, you can configure these items again for each trunking port.

Trap Settings

SNMP traps allow an SNMP agent to notify the NMS of a significant event. The switch supports two SNMP modes,

Trap mode and Inform mode.

SNMP Trap Mode—Trap

In Trap mode, the SNMP agent sends an SNMPv1 trap PDU to the NMS. No acknowledgment is sent back from the NMS so the agent has no way of knowing if the trap reached the NMS.

SNMP Trap Mode—Inform

SNMPv2 provides an inform mechanism. When an inform message is sent from the SNMP agent to the NMS, the receiver sends a response to the sender acknowledging receipt of the event. This behavior is similar to that of the get and set requests. If the SNMP agent does not receive a response from the NMS for a period of time, the agent will resend the trap to the NMS agent. The maximum timeout time is 300 sec (default is 1 sec), and the maximum number of retries is 99 times (default is 1 time). When the SNMP agent receives acknowledgement from the NMS, it will stop resending the inform messages.

Using PoE (PoE Models Only)

Power over Ethernet has become increasingly popular due in large part to the reliability provided by PoE

Ethernet switches that supply the necessary power to Powered Devices (PD) when AC power is not readily available or cost-prohibitive to provide locally.

Power over Ethernet can be used with:

• Surveillance cameras

• Security I/O sensors

• Industrial wireless access points

• Emergency IP phones

In fact, it’s not uncommon for video, voice, and high-rate industrial application data transfers to be integrated into one network. Moxa’s PoE switches are equipped with many advanced PoE management functions, providing vital security systems with a convenient and reliable Ethernet network. Moreover, Moxa’s advanced

PoE switches support the high power PoE+ standard, 24 VDC direct power input, and 20 ms fast recovery redundancy, Turbo Ring and Turbo Chain.

PoE Email Warning Events Settings

Since industrial Ethernet devices are often located at the endpoints of a system, these devices do not always know what is happening elsewhere on the network. This means that a PoE port connected to a PD must provide system administrators with real-time alarm 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 the PD almost instantaneously when exceptions occur. The PoE Ethernet switch supports different methods for warning engineers automatically, such as email and relay output. It also supports two digital inputs to integrate sensors into your system to automate alarms using email and relay output.

Email Warning Event Types can be divided into two basic groups: Power-Fail and PD-Failure.

PoE Warning Event Setting

Since industrial Ethernet devices are often located at the endpoints of a system, these devices do not always know what is happening elsewhere on the network. This means that a PoE port connected to a PD must provide system administrators with real-time alarm 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 the PD almost instantaneously when exceptions occur. The PoE Ethernet Switch supports different methods for warning engineers automatically, such as SNMP trap, email, and relay output. It also supports two digital inputs to integrate sensors into your system to automate alarm using email and relay output.

Using Traffic Prioritization

The Moxa switch’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 Moxa switch can inspect both IEEE 802.1p/1Q layer 2 CoS tags, and even layer 3 TOS information to provide consistent classification of the entire network. The Moxa switch’s QoS capability improves the performance and determinism of industrial networks for mission critical applications.

The Traffic Prioritization Concept

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:

• Improve network performance by controlling a wide variety of traffic and managing congestion.

• Assign priorities to different categories of traffic. For example, set higher priorities for time-critical or business-critical applications.

• Provide predictable throughput for multimedia applications, such as video conferencing or voice over IP, and minimize traffic delay and jitter.

• Improve network performance as the amount of traffic grows. Doing so will reduce costs since it will not be necessary to keep adding bandwidth to the network.

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

Moxa switch traffic prioritization depends on two industry-standard methods:

IEEE 802.1D—a layer 2 marking scheme.

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 and 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. The priority marking scheme determines the level of service that this 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.

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:

• It requires an additional 4-byte tag in the frame, which is normally optional for Ethernet networks. Without this tag, the scheme cannot work.

• 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 that allows you to 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.

The advantages of DiffServ over IEEE 802.1D are:

• You can configure how you want your switch to treat selected applications and types of traffic by assigning various grades of network service to them.

• No extra tags are required in the packet.

• DSCP uses the IP header of a packet to preserve priority across the Internet.

• DSCP is backwards compatible with IPV4 TOS, which allows operation with existing devices that use a layer

3 TOS enabled prioritization scheme.

Traffic Prioritization

Moxa switches classify 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 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:

• A packet received by the Moxa switch 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.

• 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 Moxa switch will check a packet received at the ingress port for IEEE 802.1D traffic classification, and then prioritize it based on 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 hardware of Moxa switches has multiple traffic queues that allow packet prioritization to occur. Higher priority traffic can pass through the Moxa switch without being delayed by lower priority traffic. As each packet arrives in the Moxa switch, 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. Moxa switches support two different queuing mechanisms:

3-36

Moxa Managed Ethernet Switches Featured Functions

Weight Fair: This method services all the traffic queues, giving priority to the higher priority queues.

Under most circumstances, the Weight Fair method gives high priority precedence over low priority, but in the event that high priority traffic does not reach the link capacity, lower priority traffic is not blocked.

Strict: This method services high traffic queues first; low priority queues are delayed until no more high priority data needs to be sent. The Strict method always gives precedence to high priority over low priority.

Configuring Traffic Prioritization

Quality of Service (QoS) provides a traffic prioritization capability to ensure that important data is delivered consistently and predictably. The Moxa switch can inspect IEEE 802.1p/1Q layer 2 CoS tags, and even layer 3

TOS information, to provide a consistent classification of the entire network. The Moxa switch’s QoS capability improves your industrial network’s performance and determinism for mission critical applications.

There are two QoS classification settings depending on the specific model of the switch.

Using Virtual LAN

Setting up Virtual LANs (VLANs) on your Moxa switch 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. With VLANs you can segment your network according into:

Departmental groups—You could have one VLAN for the marketing department, another for the finance department, and another for the product development department.

Hierarchical groups—You could have one VLAN for directors, another for managers, and another for general staff.

Usage groups—You could have one VLAN for email 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:

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 orignally on VLAN Marketing, for example, is moved to a port on 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-cabling.

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.

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 VLAN can be set up to contain only those devices that need to communicate with each other.

VLANs and the Rackmount switch

Your Moxa switch provides support for VLANs using IEEE Std 802.1Q-1998. This standard allows traffic from multiple VLANs to be carried across one physical link. The IEEE Std 802.1Q-1998 standard allows each port on your Moxa switch to be placed as follows:

• On a single VLAN defined in the Moxa switch

• On several VLANs simultaneously using 802.1Q tagging

The standard requires that you define the 802.1Q VLAN ID for each VLAN on your Moxa switch before the switch can use it to forward traffic:

Managing a VLAN

A new or initialized Moxa switch contains a single VLAN—the Default VLAN. This VLAN has the following definition:

VLAN Name—Management VLAN

802.1Q VLAN ID—1 (if tagging is required)

All the ports are initially placed on this VLAN, and it is the only VLAN that allows you to access the management software of the Moxa switch over the network.

3-41

Moxa Managed Ethernet Switches Featured Functions

Communication Between VLANs

If devices connected to a VLAN need to communicate to devices on a different VLAN, a router or Layer 3 switching device with connections to both VLANs needs to be installed. Communication between VLANs can only take place if they are all connected to a routing or Layer 3 switching device.

VLANs: Tagged and Untagged Membership

The Moxa switch supports 802.1Q VLAN tagging, a system that allows traffic for multiple VLANs to be carried on a single physical link (backbone, trunk). When setting up VLANs you need to understand when to use untagged and tagged membership of VLANs. Simply put, if a port is on a single VLAN it can be an untagged member, but if the port needs to be a member of multiple VLANs, tagged membership must be defined.

A typical host (e.g., clients) will be untagged members of one VLAN, defined as an Access Port in a Moxa switch, while inter-switch connections will be tagged members of all VLANs, defined as a Trunk Port in a Moxa switch.

The IEEE Std 802.1Q-1998 defines how VLANs operate within an open packet-switched network. An 802.1Q compliant packet carries additional information that allows a switch to determine which VLAN the port belongs to. If a frame is carrying the additional information, it is known as a tagged frame.

To carry multiple VLANs across a single physical link (backbone, trunk), each packet must be tagged with a

VLAN identifier so that the switches can identify which packets belong in which VLAN. To communicate between

VLANs, a router must be used.

The Moxa switch supports three types of VLAN port settings:

Access Port: The port connects to a single device that is not tagged. The user must define the default port

PVID that assigns which VLAN the device belongs to. Once the ingress packet of this Access Port egresses to another Trunk Port (the port needs all packets to carry tag information), the Moxa switch will insert this

PVID into this packet so the next 802.1Q VLAN switch can recognize it.

Trunk Port: The port connects to a LAN that consists of untagged devices, tagged devices and/or switches and hubs. In general, the traffic of the Trunk Port must have a Tag. Users can also assign a PVID to a Trunk

Port. The untagged packet on the Trunk Port will be assigned the port default PVID as its VID.

Hybrid Port: The port is similar to a Trunk port, except users can explicitly assign tags to be removed from egress packets.

The following section illustrates how to use these ports to set up different applications.

Sample Applications of VLANs Using Moxa Switches

5

In this application,

3-42

Moxa Managed Ethernet Switches Featured Functions

• Port 1 connects a single untagged device and assigns it to VLAN 5; it should be configured as Access Port with PVID 5.

• Port 2 connects a LAN with two untagged devices belonging to VLAN 2. One tagged device with VID 3 and one tagged device with VID 4. It should be configured as Trunk Port with PVID 2 for untagged device and

Fixed VLAN (Tagged) with 3 and 4 for tagged device. Since each port can only have one unique PVID, all untagged devices on the same port must belong to the same VLAN.

• Port 3 connects with another switch. It should be configured as Trunk Port GVRP protocol will be used through the Trunk Port.

• Port 4 connects a single untagged device and assigns it to VLAN 2; it should be configured as Access Port with PVID 2.

• Port 5 connects a single untagged device and assigns it to VLAN 3; it should be configured as Access Port with PVID 3.

• Port 6 connect a single untagged device and assigns it to VLAN 5; it should be configured as Access Port with PVID 5.

• Port 7 connects a single untagged device and assigns it to VLAN 4; it should be configured as Access Port with PVID 4.

After the application is properly configured:

• Packets from Device A will travel through Trunk Port 3 with tagged VID 5. Switch B will recognize its VLAN, pass it to port 6, and then remove tags received successfully by Device G, and vice versa.

• Packets from Devices B and C will travel through Trunk Port 3 with tagged VID 2. Switch B recognizes its

VLAN, passes it to port 4, and then removes tags received successfully by Device F, and vice versa.

• Packets from Device D will travel through Trunk Port 3 with tagged VID 3. Switch B will recognize its VLAN, pass to port 5, and then remove tags received successfully by Device H. Packets from Device H will travel through Trunk Port 3 with PVID 3. Switch A will recognize its VLAN and pass it to port 2, but will not remove tags received successfully by Device D.

• Packets from Device E will travel through Trunk Port 3 with tagged VID 4. Switch B will recognize its VLAN, pass it to port 7, and then remove tags received successfully by Device I. Packets from Device I will travel through Trunk Port 3 with tagged VID 4. Switch A will recognize its VLAN and pass it to port 2, but will not remove tags received successfully by Device E.

Using Multicast Filtering

Multicast filtering improves the performance of networks that carry multicast traffic. This section explains multicasts, multicast filtering, and how multicast filtering can be implemented on your Moxa switch.

The Concept of Multicast Filtering

What is an IP Multicast?

A multicast is a packet sent by one host to multiple hosts. Only those hosts that belong to a specific multicast group will receive the multicast. If the network is set up correctly, a multicast can only be sent to an end-station or a subset of end-stations on a LAN or VLAN that belong to the multicast group. Multicast group members can be distributed across multiple subnets, so that multicast transmissions can occur within a campus LAN or over a WAN. In addition, networks that support IP multicast send only one copy of the desired information across the network until the delivery path that reaches group members diverges. To make more efficient use of network bandwidth, it is only at these points that multicast packets are duplicated and forwarded. A multicast packet has a multicast group address in the destination address field of the packet’s IP header.

Benefits of Multicast

The benefits of using IP multicast are:

• It uses the most efficient, sensible method to deliver the same information to many receivers with only one transmission.

• It reduces the load on the source (for example, a server) since it will not need to produce several copies of the same data.

• It makes efficient use of network bandwidth and scales well as the number of multicast group members increases.

• Works with other IP protocols and services, such as Quality of Service (QoS).

Multicast transmission makes more sense and is more efficient than unicast transmission for some applications.

For example, multicasts are often used for video-conferencing, since high volumes of traffic must be sent to several end-stations at the same time, but where broadcasting the traffic to all end-stations would cause a substantial reduction in network performance. Furthermore, several industrial automation protocols, such as

Allen-Bradley, EtherNet/IP, Siemens Profibus, and Foundation Fieldbus HSE (High Speed Ethernet), use multicast. These industrial Ethernet protocols use publisher/subscriber communications models by multicasting packets that could flood a network with heavy traffic. IGMP Snooping is used to prune multicast traffic so that it travels only to those end destinations that require the traffic, reducing the amount of traffic on the Ethernet LAN.

Multicast Filtering

Multicast filtering ensures that only end-stations that have joined certain groups receive multicast traffic. With multicast filtering, network devices only forward multicast traffic to the ports that are connected to registered end-stations. The following two figures illustrate how a network behaves without multicast filtering, and with multicast filtering.

3-47

Moxa Managed Ethernet Switches

Network without multicast filtering

Featured Functions

All hosts receive the multicast traffic, even if they don’t need it.

Network with multicast filtering

Hosts only receive dedicated traffic from other hosts belonging to the same group.

NOTE

Multicast Filtering and Moxa’s Industrial Rackmount Switches

The Moxa switch has three ways to achieve multicast filtering: IGMP (Internet Group Management Protocol)

Snooping, GMRP (GARP Multicast Registration Protocol), and adding a static multicast MAC manually to filter multicast traffic automatically.

Snooping Mode

Snooping Mode allows your switch to forward multicast packets only to the appropriate ports. The switch

snoops on exchanges between hosts and an IGMP device, such as a router, to find those ports that want to join a multicast group, and then configures its filters accordingly.

IGMP Snooping Enhanced Mode

Snooping Enhanced Mode allows your switch to forward multicast packets to the Moxa switch’s member port only. If you disable Enhanced Mode, data streams will run to the querier port as well as the member port.

Query Mode

Query mode allows the Moxa switch to work as the Querier if it has the lowest IP address on the subnetwork to which it belongs.

IGMP Snooping Enhanced mode is only provided in Layer 2 switches.

IGMP querying is enabled by default on the Moxa switch to ensure proceeding query election. Enable query mode to run multicast sessions on a network that does not contain IGMP routers (or queriers). Query mode

3-48

Moxa Managed Ethernet Switches Featured Functions

NOTE

allows users to enable IGMP snooping by VLAN ID. Moxa switches support IGMP snooping version 1, version 2 and version 3. Version 2 is compatible with version 1.The default setting is IGMP V1/V2. "

Moxa Layer 3 switches are compatible with any device that conforms to the IGMP v2 and IGMP v3 device protocols. Layer 2 switches only support IGMP v1/v2.

IGMP Multicast Filtering

IGMP is used by IP-supporting network devices to register hosts with multicast groups. It can be used on all

LANs and VLANs that contain a multicast capable IP router, and on other network devices that support multicast filtering. Moxa switches support IGMP version 1, 2 and 3. IGMP version 1 and 2 work as follows::

• The IP router (or querier) periodically sends query packets to all end-stations on the LANs or VLANs that are connected to it. For networks with more than one IP router, the router with the lowest IP address is the querier. A switch with IP address lower than the IP address of any other IGMP queriers connected to the LAN or VLAN can become the IGMP querier.

• When an IP host receives a query packet, it sends a report packet back that identifies the multicast group that the end-station would like to join.

• When the report packet arrives at a port on a switch with IGMP Snooping enabled, the switch knows that the port should forward traffic for the multicast group, and then proceeds to forward the packet to the router.

• When the router receives the report packet, it registers that the LAN or VLAN requires traffic for the multicast groups.

• When the router forwards traffic for the multicast group to the LAN or VLAN, the switches only forward the traffic to ports that received a report packet.

IGMP version 3 supports “source filtering,” which allows the system to define how to treat packets from specified source addresses. The system can either white-list or black-list specified sources.

GMRP (GARP Multicast Registration Protocol)

Moxa switches support IEEE 802.1D-1998 GMRP (GARP Multicast Registration Protocol), which is different from

IGMP (Internet Group Management Protocol). GMRP is a MAC-based multicast management protocol, whereas

IGMP is IP-based. GMRP provides a mechanism that allows bridges and end stations to register or de-register

Group membership information dynamically. GMRP functions similarly to GVRP, except that GMRP registers multicast addresses on ports. When a port receives a GMRP-join message, it will register the multicast address to its database if the multicast address is not registered, and all the multicast packets with that multicast address are able to be forwarded from this port. When a port receives a GMRP-leave message, it will de-register the multicast address from its database, and all the multicast packets with this multicast address will not be able to be forwarded from this port.

Static Multicast MAC

Some devices may only support multicast packets, but not support either IGMP Snooping or GMRP. The Moxa switch supports adding multicast groups manually to enable multicast filtering.

Enabling Multicast Filtering

Use the serial console or web interface to enable or disable IGMP Snooping and IGMP querying. If IGMP

Snooping is not enabled, then IP multicast traffic is always forwarded, flooding the network.

Configuring IGMP Snooping

IGMP Snooping provides the ability to prune multicast traffic so that it travels only to those end destinations that require that traffic, thereby reducing the amount of traffic on the Ethernet LAN.

Using Bandwidth Management

In general, one host should not be allowed to occupy unlimited bandwidth, particularly when the device malfunctions. For example, so-called “broadcast storms” could be caused by an incorrectly configured topology, or a malfunctioning device. Moxa industrial Ethernet switches not only prevents broadcast storms, but can also be configured to a different ingress rate for all packets, giving administrators full control of their limited bandwidth to prevent undesirable effects caused by unpredictable faults.

Authentication Certificate

NOTE

The switch offers two methods to encrypt the communication: SSL Certificate and SSH Key. You can only use one of the encryption types at the same time. SSL (Secure Socket Layer) is mainly for web communication security. It secures the data between two application points. SSH (Secure Shell) is a security protocol based on the Application Layer and Transport Layer. It encrypts the data for security.

The switch only supports one type of the Authentication Certificate at a time.

Check the Authentication Certificate, and then click Activate to complete.

Using Port Access Control

The Moxa switch provides two kinds of Port-Based Access Control: Static Port Lock and IEEE 802.1X.

Static Port Lock

In this case, the Moxa switch can also be configured to protect static MAC addresses for a specific port. With the

Port Lock function, these locked ports will not learn any additional addresses, but only allow traffic from preset static MAC addresses, helping to block hackers and careless usage.

IEEE 802.1X

The IEEE 802.1X standard defines a protocol for client/server-based access control and authentication. The protocol restricts unauthorized clients from connecting to a LAN through ports that are open to the Internet, and which otherwise would be readily accessible. The purpose of the authentication server is to check each client that requests access to the port. The client is only allowed access to the port if the client’s permission is authenticated.

Three components are used to create an authentication mechanism based on 802.1X standards:

Client/Supplicant, Authentication Server, and Authenticator.

Client/Supplicant: The end station that requests access to the LAN and switch services and responds to the requests from the switch.

Authentication Server: The server that performs the actual authentication of the supplicant.

Authenticator: Edge switch or wireless access point that acts as a proxy between the supplicant and the authentication server, requesting identity information from the supplicant, verifying the information with the authentication server, and relaying a response to the supplicant.

The Moxa switch acts as an authenticator in the 802.1X environment. A supplicant and an authenticator exchange EAPOL (Extensible Authentication Protocol over LAN) frames with each other. We can either use an external RADIUS server as the authentication server, or implement the authentication server in the Moxa switch by using a Local User Database as the authentication look-up table. When we use an external RADIUS

3-60

Moxa Managed Ethernet Switches Featured Functions

server as the authentication server, the authenticator and the authentication server exchange EAP frames between each other.

Authentication can be initiated either by the supplicant or the authenticator. When the supplicant initiates the authentication process, it sends an EAPOL-Start frame to the authenticator. When the authenticator initiates the authentication process or when it receives an EAPOL Start frame, it sends an EAP Request/Identity frame to ask for the username of the supplicant.

Using Auto Warning

Since industrial Ethernet devices are often located at the endpoints 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 alarm 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 Moxa switch supports different approaches to warn engineers automatically, such as email and relay output. It also supports two digital inputs to integrate sensors into your system to automate alarms by email and relay output.

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:

Configure 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 Alarm Events setting subsection).

Configure Email Settings

To configure a Moxa switch’s email setup from the serial, Telnet, or web console, enter your Mail Server

IP/Name (IP address or name), Account Name, Account Password, Retype New Password, and the email address to which warning messages will be sent.

Activate your settings and if necessary, test the email

After configuring and activating your Moxa switch’s Event Types and Email Setup, you can use the Test Email function to see if your e-mail addresses and mail server address have been properly configured.

Configuring Relay Warning

The Auto Relay Warning function uses relay output to alert the user when certain user-configured events take place. There are two basic steps required to set up the Relay Warning function:

Configure Relay 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 Relay Alarm Events setting subsection).

Activate your settings

After completing the configuration procedure, you will need to activate your Moxa switch’s Relay Event Types.

Configuring Event Types

Event Types can be divided into two basic groups: System Events and Port Events. System Events are related to the overall function of the switch, whereas Port Events are related to the activity of a specific port.

The Moxa switch supports two relay outputs. You can configure which relay output is related to which events, which helps administrators identify the importance of the different events.

System Events Warning Relay output is triggered when…

Power Transition (On -> Off) Moxa switch is powered down

Power Transition (Off -> On) Moxa switch is powered up

Using Line-Swap-Fast-Recovery

The Line-Swap Fast Recovery function, which is enabled by default, allows the Moxa switch to return to normal operation extremely quickly after devices are unplugged and then re-plugged into different ports. The recovery time is on the order of a few milliseconds (compare this with standard commercial switches for which the recovery time could be on 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 below.

Using Set Device IP

To reduce the effort required to set up IP addresses, the Moxa switch 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 the Moxa switch to assign specific IP addresses automatically to connected devices that are equipped with DHCP Client or RARP protocol. In effect, the Moxa switch acts as a DHCP server by assigning a connected device with a specific IP address stored in its internal memory. Each time the connected device is switched on or rebooted, the Moxa switch sends the device the desired IP address.

Take the following steps to use the Set device IP function:

STEP 1Set up the connected devices

Set up those Ethernet-enabled devices connected to the Moxa switch 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 the Obtain an IP address

automatically option.

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 Moxa switch’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 following step.

STEP 2

Configure the Moxa switch’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 on 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.

Configuring DHCP Relay Agent

The DHCP Relay Agent makes it possible for DHCP broadcast messages to be sent over routers. The DHCP

Relay Agent enables DHCP clients to obtain IP addresses from a DHCP sever on a remote subnet, or those that are not located on the local subnet.

DHCP Relay Agent (Option 82)

Option 82 is used by the relay agent to insert additional information into the client’s DHCP request. The Relay

Agent Information option is inserted by the DHCP relay agent when forwarding client-originated DHCP packets to a DHCP server. Servers can recognize the Relay Agent Information option and use the information to implement IP addresses to Clients.

When Option 82 is enabled on the switch, a subscriber device is identified by the switch port through which it connects to the network (in addition to its MAC address). Multiple hosts on the subscriber LAN can be connected to the same port on the access switch and are uniquely identified.

The Option 82 information contains 2 sub-options, Circuit ID and Remote ID, which define the relationship between the end device IP and the DHCP Option 82 server. The Circuit ID is a 4-byte number generated by the

Ethernet switch—a combination of physical port number and VLAN ID. The format of the Circuit ID is shown below:

FF–VV–VV–PP

This is where the first byte “FF” is fixed to “01”, the second and the third byte “VV-VV” is formed by the port

VLAN ID in hex, and the last byte “PP” is formed by the port number in hex. For example:

01–00–0F–03 is the “Circuit ID” of port number 3 with port VLAN ID 15.

The “Remote ID” identifies the relay agent itself and can be one of the following:

1. The IP address of the relay agent.

3-70

2. The MAC address of the relay agent.

3. A combination of IP address and MAC address of the relay agent.

4. A user-defined string.

Using Diagnosis

The Moxa switch provides three 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. Using a mirror port allows the network administrator to sniff the observed port to keep tabs on network activity.

Please note that two types of mirror port settings are available, depending on the specific model of switch. In

Type 1, the switches support multi-to-one and one-to-one mirror function. In Type 2, the switches support only one-to-one mirror function.

Ping when using the Web Browser interface.

LLDP Function

Overview

LLDP is an OSI Layer 2 protocol defined by IEEE 802.11AB. LLDP standardizes the self-identification advertisement method, and allows each networking device, such as a Moxa managed switch, to periodically send its system and configuration information to its neighbors. Because of this, all LLDP devices are kept informed of each other’s status and configuration, and with SNMP, this information can be transferred to Moxa’s

MXview for auto-topology and network visualization.

From the switch’s web interface, you can enable or disable LLDP, and set the LLDP transmit interval. In addition, you can view each switch’s neighbor-list, which is reported by its network neighbors. Most importantly, enabling the LLDP function allows Moxa’s MXview to automatically display the network’s topology and system setup details, such as VLAN and Trunking, for the entire network.

Using Monitor

You can monitor statistics in real time from the Moxa switch’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 Moxa switch’s 18 ports. Click 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 Moxa switch, 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 TX Error, RX Error

Packets activity. 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 or 1G Ports or Port i, in which i = 1, 2, …, G2, from the left pull-down list. The Port i options are identical to the Monitor by System function discussed above, in that users can view graphs that show All Packets, TX Packets, RX Packets, or Error Packets activity, but in this case, only for an individual port. The All 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 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 blue colored bar shows Uni-cast packets, the red

colored bar shows Multi-cast packets, and the orange colored bar shows Broad-cast packets. The graph is updated every few seconds, allowing the user to analyze data transmission activity in real-time.

Monitor by SFP

Optical fiber is commonly used for long distance data transmission. However, when link issues occur, it is very costly to trouble shoot the fiber cable and fiber transceiver at remote sites. To solve this problem, Moxa industrial Ethernet switches provide digital diagnostic and monitoring functions on Moxa SFP optical fiber links and allow users to measure optical parameters and its performance from center site. This function can greatly facilitate the trouble shooting process for optical fiber links and reduce costs for onsite debug.

Using Access Control List

NOTE

Access Control Lists are available in Moxa Layer 3 switches.

Access control lists (ACL) increase the flexibility and security of networking management.

ACL provides traffic filter capabilities for ingress or egress packets. Moxa access control list helps manage filter criteria for diverse protocols and allows users to configure customized filter criteria. For example, users can deny access to specific source or destination IP/MAC addresses.

The Moxa access control list configuration interface is easy-to-use. Users can quickly establish filtering rules, manage rule priorities, and view overall settings in the display page.

The ACL Concept

What is ACL?

Access control list is a basic traffic filter for ingress and egress packets. It can examine each Ethernet packet’s information and take necessary action. Moxa Layer 3 switches provide complete filtering capability. Access list criteria could include the source or destination IP address of the packets, the source or destination MAC address of the packets, IP protocols, or other information. The ACL can check these criteria to decide whether to permit or deny access to a packet.

Benefits of ACL

ACL has per interface, per packet direction, and per protocol filtering capability. These features can provide basic protection by filtering specific packets. The main benefits of ACL are as follows:

3-77

Moxa Managed Ethernet Switches Featured Functions

Manage authority of hosts: ACL can restrict specific devices through MAC address filtering. The user can deny all packets or only permit packets that come from specific devices.

Subnet authority management: Configure filtering rules for specific subnet IP addresses. ACL can restrict packets from or to specific subnets.

Network security: The demand for networking security is growing. ACL can provide basic protection which works similarly to an Ethernet firewall device.

Control traffic flow by filtering specific protocols: ACL can filter specific IP protocols such as TCP or

UDP packets.

How ACL works

ACL working structure is based on access lists. Each access list is a filter. When a packet enters into or exits from a switch, ACL will compare the packet to the rules in the access lists, starting from the first rule. If a packet is rejected or accepted by the first rule, the switch will drop or pass this packet directly without checking the rest of the lower-priority rules. In the other words, Access Control List has “Priority Index” as its attribute to define the priority in the web configuration console.

There are two types of settings for an ACL: the list settings, and the rule settings. In order to be created, an

Access Control List needs the following list settings: Name, Priority Index, Filter Type, and Ports to Apply. Once created, each Access Control List has its own set of rule settings. Priority Index represents the priority of the names in the access list. Names at Priority Index 1 have first priority in packet filtering. The Priority Index is adjustable whenever users need to change the priority. In this function, there are two types of packet filtering available:

• IP based

• MAC Based

Filter type defines whether the access list will examine packets based on IP or MAC address. This type affects what detailed rules can be edited. Then, assign the ports you would like to apply the list to. You can also define

Ingress and Egress per port.

After adding a new access control list, you can also create new rules for the access control list. Each ACL group accepts 10 rules. Rules can filter packets by source and destination IP/MAC address, IP protocol, TCP/UDP Port,

Ethernet Type, and VLAN ID.

After all rules are set, ACL starts to filter the packets by the rule with the highest Priority Index (smaller number, higher priority). Once a rule denies or accepts its access, the packet will be dropped or passed.

Access Control List Configuration and Setup

Access Control List Settings

Creating an access control list starts at the Access Control List Setting page.

3-78

Moxa Managed Ethernet Switches Featured Functions

In this page, you can mainly configure two settings:

Add/Modify Access Control List

This function lets you Add a new access control list or Modify an existing access control list. The operation depends on the Priority Index you select. If the selected priority index is still empty, you can start by creating a new access control list. Parameters for editing are:

Priority Index: ACL checking sequence is based on this index. Smaller index numbers have higher priority for packet filtering. If a packet is filtered by an access list with higher priority, those access lists with lower priority will not being executed.

Note that Priority Index is not a one-to-one index for each list name. It changes when swapping the priority of different access control lists.

The maximum Priority Index number is 16

Name: You can name the access control list in this field. This is the access list’s unique name.

Filter: Select filtering by either IP or MAC address. Detailed settings can be configured in the Access

Control Rule Settings page.

Ingress Port Map/Egress Port Map: You can choose which ports to apply the rules to. The Ingress and

Egress condition uses OR logic. This means a packet only needs to match one ingress or egress port rule to be examined.

If a selected priority index is already in the access control list, then you can modify these parameters listed above. After configuration, click Activate to confirm the settings. Then you will see a new list appear in the

Access Control List table.

Adjust ACL Priority Index

Changing an established access control list’s priority is easy. Moxa provides a simple interface to let you easily adjust priority. Follow the three steps below to adjust the priority:

Step 1: Select the list

Step 2: Click the Up/Down button to adjust the sequence. The Priority Index will change with the list’s position.

Step 3: Click the Activate button to confirm the settings.

Access Control Rule Settings

You can edit an access control list’s rules on this page. Each ACL can include up to 10 rules.

First, select the access control list you would like to edit based on the Priority Index. The Ingress/Egress Port map will display the port settings.

The Port Configuration Display page provides a complete view of all ACL settings. In this page, you can view the rules by Ingress port, Egress port, or Priority Index. Click the drop-down menu to select the Port or Priority

Index, and all the rules will be displayed in the table.

NOTE

For EDS-828 and PT-7828 series, there are two limitations on ACL settings. Based on the ingress port type of

ACL rules, there are two types for the limitation of numbers.

Limitation Type 1:

When rules contain Ingress Fast Ethernet (FE) ports, the

Number should NOT be greater than 160.

Limitation Type 2:

When rules contain Ingress Gigabit Ethernet (GE) ports or no Ingress ports, the

Number should NOT be greater than 40.

Example 1 for Limitation 1

Rule A contains 3 ingress FE ports and 4 egress FE ports, and it results in the number of 3 x 4 = 12.

Rule B contains 5 ingress FE ports and 6 egress GE ports, and it results in the number of 5 x 6 = 30.

Rule C contains 7 ingress FE ports and no egress port, and it results in the number of 7.

Make sure the amount of those numbers “12+30+7” is not greater than 160.

Example 2 for Limitation 2

Rule D contains 1 ingress GE port and 2 egress FE ports, and it results in the number of 1 x 2 = 2.

Rule E contains 3 ingress GE ports and 4 egress GE ports, and it results in the number of 3 x 4 = 12.

Rule F contains 5 ingress GE ports and no egress ports, and it results in the number of 5.

Rule G contains no ingress ports and 6 FE egress ports, and it results in the number of 6.

Rule H contains no ingress ports and 7 GE egress ports, and it results in the number of 7.

Make sure the amount of those numbers “2+12+5+6+7” is not greater than 40.

Example 3 for Limitation 1 and 2

Rule Z contains 3 ingress FE ports, 2 ingress GE ports, and 5 egress GE ports.

It results in the number of 3 x 5 = 15 in Limitation 1, and 2 x 5 = 10 in Limitation 2.

Make sure the amount in limitation 1, “15”, is not greater than 160.

Make sure the amount in limitation 2, “10”, is not greater than 40.

EDS Configurator GUI

EDS Configurator is a comprehensive Windows-based GUI that is used to configure and maintain multiple Moxa switches. A suite of useful utilities is available to help you locate Moxa switches attached to the same LAN as the

PC host (regardless of whether or not you know the IP addresses of the switches), connect to a Moxa switch whose IP address is known, modify the network configurations of one or multiple Moxa switches, and update the firmware of one or more Moxa switch. EDS Configurator is designed to provide you with instantaneous control of all of your Moxa switches, regardless of location. You may download the EDS Configurator software from Moxa’s website free of charge.

Unlock Server

The Unlock Server function is used to open a password protected switch so that the user can modify its configuration, import/export a configuration, and perform other procedures. There are six possible responses under the Status column. The Status of a Moxa switch indicates how Moxa EtherDevice Switch Configurator located the switch, and what type of password protection it has.

The six options are as follows (note that the term Fixed is borrowed from the standard fixed IP address networking terminology):

Locked

The switch is password protected, Broadcast Search was used to locate it, and the password has not yet been entered from within the current Configurator session.

Unlocked

The switch is password protected, Broadcast Search was used to locate it, and the password was entered from within the current Configurator session. Henceforth during this Configurator session, activating various utilities for this switch will not require re-entering the server password.

Blank

The Moxa switch is not password protected, and Broadcast Search was used to locate it.

Follow the steps given below to unlock a locked Moxa switch (i.e., Moxa switch with Status “Locked” or “Locked

Fixed”). Highlight the server (from the Moxa EtherDevice Switch list in the Configurator window’s left pane), and then click the Unlock toolbar icon , or select Unlock from the Configuration menu.

1. Enter the switch’s User Name and Password when prompted, and then click OK.
