PT-7728 User’s Manual Featured Functions SNMP Inform Mode 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 that the event was received. This behavior is similar to 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 is 300 sec. (default is 1 sec.
PT-7728 User’s Manual Featured Functions Turbo Ring V2 Turbo Ring Topology Ring Ring Recovery Time < 20 ms < 300 ms NOTE Turbo Chain Chain < 20 ms STP Ring, Mesh Up to 30 sec. RSTP Ring, Mesh Up to 5 sec Most managed switches by Moxa support two proprietary Turbo Ring protocols: y y Turbo Ring refers to the original version of Moxa’s proprietary redundant ring protocol, which has a recovery time of under 300 ms.
PT-7728 User’s Manual Featured Functions Turbo Ring with even number of switches If the number of Ethernet switches in the Turbo Ring is 2N (an even number), the backup segment is one of the two segments connected to the (N+1)st switch (i.e., the unit directly opposite the master). Master Turbo Ring with odd number switches If the number of Ethernet switches in the Turbo Ring is 2N+1 (an odd number), the backup segment is the (N+1)st segment counting counterclockwise.
PT-7728 User’s Manual Featured Functions Ring Coupling Configuration For some systems, it may not be convenient to connect all devices in the system in a single redundant ring, since some devices could be located in a remote area. For these systems, Ring Coupling can be used to group devices into smaller redundant rings that communicate with each other.
PT-7728 User’s Manual Featured Functions Note that the ring coupling settings for a Turbo Ring V2 are different from a Turbo 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 up a coupling control port, so Turbo Ring V2 does not require a coupling control line. The Coupling Port (Backup) on Switch A is used for the backup path and connects directly to a network port on Switch C.
PT-7728 User’s Manual Featured Functions Configuring Turbo Ring "Current Status" Items Now Active This shows which communication protocol is in use: Turbo Ring, Turbo Ring V2, Turbo Chain, RSTP, or none. Master/Slave This indicates whether or not the PT-7728 is the master of the Turbo Ring. This field appears only for Turbo Ring or Turbo Ring V2. NOTE The user does not need to assign the master to use Turbo Ring or Turbo Ring V2.

Factory Default Port 1-4 (without Gigabit Ethernet module) Port 4-2 (with Gigabit Ethernet module) Configuring Turbo Ring V2 NOTE When using a dual-ring architecture, users must complete configuration for both Ring 1 and Ring 2. The status of both rings will appear under Current Status.
PT-7728 User’s Manual NOTE Featured Functions The user does not need to assign the master to use Turbo Ring or Turbo Ring V2. If no master is assigned, the Turbo Ring protocol will automatically assign master status to one of the PT series Ethernet switches in the ring. The master is only used to determine which segment serves as the backup path.
PT-7728 User’s Manual Featured Functions Redundant Ports Setting Description 1st Port This specifies which port on the PT-7728 will be used as the first redundant port. 2nd Port This specifies which port on the PT-7728 will be used as the second redundant port.
PT-7728 User’s Manual Featured Functions The Turbo Chain Concept Moxa’s Turbo Chain is an advanced software technology that gives network administrators the flexibility to construct any type of redundant network topology. When using a Turbo Chain, you first connect the Ethernet switches in a chain and then simply link the two ends of the chain to an Ethernet network, as illustrated in the following figure. Turbo Chain can be used on industrial networks that have a complex topology.
PT-7728 User’s Manual Featured Functions Member Switch Configuration Tail Switch Configuration Explanation of “Current Status” Items Now Active Shows which communication protocol is in use: Turbo Ring, Turbo Ring V2, Turbo Chain, RSTP, or none.

PT-7728 User’s Manual Featured Functions ¾ It 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 PT-7728. This feature is particularly helpful when PT-7728 ports connect to older equipment, such as legacy switches. You get essentially the same functionality with RSTP and STP. To see how the two systems different, please refer to Differences between RSTP and STP later in this chapter.
PT-7728 User’s Manual Featured Functions 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. STP will determine which path between each bridged segment is most efficient, and then assign a specific reference point on the network. When the most efficient path has been identified, the other paths are blocked.
PT-7728 User’s Manual y y Featured Functions 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 PT-7728 is 32768. Each port has a cost that specifies the efficiency of each link.
PT-7728 User’s Manual Featured Functions 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 can 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.
PT-7728 User’s Manual Featured Functions 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 only depend on the physical connections. Consequently, some network configurations will result in VLANs being subdivided into a number of isolated sections by the STP system.
PT-7728 User’s Manual Featured Functions At the top of this page, the user can check the Current Status of this function. For RSTP, you will see: Now Active: This field shows which communication protocol is being used—Turbo Ring, RSTP, or neither. Root/Not Root This field appears only for RSTP mode. It indicates whether or not this PT-7728 is the Root of the Spanning Tree (the root is determined automatically). At the bottom of this page, the user can configure the Settings for the selected protocol.
PT-7728 User’s Manual NOTE Featured Functions We suggest that you disable the Spanning Tree Protocol for ports that are connected directly to a device (PLC, RTU, etc.) as opposed to network equipment. This will prevent unnecessary negotiation. Port Priority Setting Numerical value selected by user Description This specifies the port’s priority as a node on the Spanning Tree topology. Lower values correspond to higher priority.
PT-7728 User’s Manual Featured Functions Using Traffic Prioritization The PT-7728’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.
PT-7728 User’s Manual Featured Functions 2 3 4 5 6 7 Standard (spare) Excellent Effort (business critical) Controlled Load (streaming multimedia) Video (interactive media); less than 100 milliseconds of latency and jitter Voice (interactive voice); less than 10 milliseconds of latency and jitter Network Control Reserved traffic Even though the IEEE 802.
PT-7728 User’s Manual Featured Functions The PT-7728 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 PT-7728 hardware has multiple traffic queues that allow packet prioritization to occur.
PT-7728 User’s Manual Strict Featured Functions 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.
PT-7728 User’s Manual Featured Functions TOS/DiffServ Mapping Setting Low/Normal/ Medium/High Description This maps different TOS values to 4 different egress queues. Factory Default 1 to 16: Low 17 to 32: Normal 33 to 48: Medium 49 to 64: High Using Virtual LAN Setting up Virtual LANs (VLANs) on your PT-7728 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.
PT-7728 User’s Manual Featured Functions 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 y 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.
PT-7728 User’s Manual 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 PT-7728 supports 802.
PT-7728 User’s Manual Featured Functions Sample Applications of VLANs using PT-7728 In this application, y Port 1 connects a single untagged device and assigns it to VLAN 5; it should be configured as Access Port with PVID 5. y 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.
PT-7728 User’s Manual y Featured Functions 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. Configuring Virtual LAN VLAN Settings To configure 802.
PT-7728 User’s Manual Featured Functions ATTENTION For communication redundancy in the VLAN environment, set Redundant Port Coupling Port and Coupling Control Port as Trunk Port since these ports act as the backbone to transmit all packets of different VLANs to different PT-7728 units. Port PVID Setting Description Factory Default VID range from 1 This sets the default VLAN ID for untagged devices that 1 to 4094 connect to the port.
PT-7728 User’s Manual Featured Functions VLAN Table In 802.1Q VLAN table, you can review the VLAN groups that were created, Joined Access Ports, and Trunk Ports, and in Port-based VLAN table, you can review the VLAN group and Joined port. NOTE The physical network can have a maximum of 64 VLAN settings. Using Multicast Filtering Multicast filtering improves the performance of networks that carry multicast traffic.
PT-7728 User’s Manual Featured Functions 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.
PT-7728 User’s Manual Featured Functions Multicast Filtering and Moxa PowerTrans Switch The PT-7728 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. IGMP (Internet Group Management Protocol) Snooping Mode Snooping Mode allows your switch to forward multicast packets only to the appropriate ports.
PT-7728 User’s Manual Featured Functions Static Multicast MAC Some devices may only support multicast packets, but not support either IGMP Snooping or GMRP. The PT-7728 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.
PT-7728 User’s Manual Featured Functions IGMP Snooping Setting Enable/Disable Description This enables or disables the IGMP Snooping function per VLAN. Factory Default Enabled if IGMP Snooping Enabled Globally Querier Setting Enable/Disable Description Factory Default This enables or disables the PT-7728’s querier function.
PT-7728 User’s Manual Featured Functions Add New Static Multicast Address to the List Setting MAC Address Description Input the multicast MAC address of this host. Factory Default None Description Input the number of the VLAN that the host with this MAC address belongs to. Factory Default None Description Checkmark the appropriate check boxes to select the join ports for this multicast group.
PT-7728 User’s Manual Featured Functions 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.
PT-7728 User’s Manual Featured Functions Using Port Access Control The PT-7728 provides two kinds of Port-Base Access Control. One is Static Port Lock and the other is IEEE 802.1X. Static Port Lock The PT-7728 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.
PT-7728 User’s Manual Setting MAC Address Port Featured Functions Description Add the static unicast MAC address into the address table. Fix the static address with a dedicated port.

Port Access Control Table The port status will show authorized or unauthorized.
PT-7728 User’s Manual Featured Functions 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.
PT-7728 User’s Manual Featured Functions 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. System Events Warning e-mail is sent when… Switch Cold Start Power is cut off and then reconnected. Switch Warm Start Power Transition (OnÆOff) PT-7728 is rebooted, such as when network parameters are changed (IP address, subnet mask, etc.).
