PT-7728 User’s Manual NOTE Featured Functions 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. Turbo Ring V2 refers to the new generation Turbo Ring, which has a recovery time of under 20 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). 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 Determining the Redundant Path for Turbo Ring V2 For Turbo Ring V2, the backup segment is the segment connected to the 2nd redundant port on the master. Master Please refer to Configuring Turbo Ring V2 later in this chapter. 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.
PT-7728 User’s Manual Featured Functions To configure the ring coupling for a Turbo Ring, select two PT series Ethernet switches (e.g., Switch A and B in the above figure) in the ring, and another two PT series Ethernet switches in the adjacent ring (e.g., Switch C and D). Select two ports on each switch to be used as coupling ports and 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).
PT-7728 User’s Manual Featured Functions Dual-Homing Configuration for Turbo Ring V2 Dual-homing is only supported with Turbo Ring V2 and is used to connect two networks through a single Ethernet switch. The primary path is the operating connection, and the backup path is a back-up connection that is activated in the event that the primary path connection fails.
PT-7728 User’s Manual Featured Functions "Current Status" Items Now Active This shows which communication protocol is in use: Turbo Ring, Turbo Ring V2, 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.
PT-7728 User’s Manual Featured Functions Enable Ring Coupling Setting Enable Disable Description This specifies that this PT-7728 will be a ring coupler.

PT-7728 User’s Manual Featured Functions 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. The PT-7728’s STP feature is disabled by default. To be completely effective, you must enable RSTP/STP on every PT-7728 connected to your network.
PT-7728 User’s Manual Featured Functions If STP is enabled, it will detect duplicate paths and prevent, or block, one of them from forwarding traffic. In the following example, STP determined that traffic from LAN segment 2 to LAN segment 1 should flow through Bridges C and A because this path has a greater bandwidth and is therefore more efficient.
PT-7728 User’s Manual Featured Functions How STP Works When enabled, STP determines the most appropriate path for traffic through a network. The method is described below: STP Requirements Before STP can configure the network, the system must satisfy the following requirements: y Communication must be established between all bridges. This communication is carried out using Bridge Protocol Data Units (BPDUs), which are transmitted in packets with a known multicast address.
PT-7728 User’s Manual Featured Functions STP Reconfiguration Once the network topology has stabilized, each bridge listens for "Hello" BPDUs that are 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.
PT-7728 User’s Manual y y y y y y Featured Functions Bridge A has been selected as the Root Bridge, since it was determined to have the lowest Bridge Identifier on the network. 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. Ports 1 of Bridges B, C, X, and Y are all Root Ports sine they are nearest to the Root Bridge, and therefore have the most efficient path.
PT-7728 User’s Manual Featured Functions Configuring STP/RSTP The following figures indicate which Spanning Tree Protocol parameters can be configured. A more detailed explanation of each parameter is given below the figure. 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.
PT-7728 User’s Manual Featured Functions Forwarding Delay Setting Numerical value input by user Description This specifies the amount of time this device will wait before checking to see if it should change to a different state. Factory Default 15 (sec.) Hello Time (sec.) Setting Numerical value input by user Description Factory Default This specifies the time interval between "hello" 2 messages broadcast by the root of the Spanning Tree topology.
PT-7728 User’s Manual Featured Functions Port Status Indicates the current Spanning Tree status of this port. Forwarding indicates normal transmission and Blocking indicates blocked transmission. Configuration Limits of RSTP/STP The Spanning Tree Algorithm places limits on three of the configuration items: [Eq. 1]: 1 sec ≦ Hello Time ≦ 10 sec [Eq. 2]: 6 sec ≦ Max. Age ≦ 40 sec [Eq. 3]: 4 sec ≦ Forwarding Delay ≦ 30 sec These three variables are further restricted by the following two inequalities: [Eq.
PT-7728 User’s Manual y y Featured Functions 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. This will save cost by reducing the need to keep adding bandwidth to the network.
PT-7728 User’s Manual Featured Functions 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.
PT-7728 User’s Manual Featured Functions Configuring Traffic Prioritization Quality of Service (QoS) provides a traffic prioritization capability to ensure that important data is delivered consistently and predictably. The PT-7728 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 PT-7728’ QoS capability improves your industrial network’s performance and determinism for mission critical applications.
PT-7728 User’s Manual Featured Functions Inspect COS Setting Enable/Disable Description This enables or disables the PT-7728 to inspect the 802.1p COS tag in the MAC frame to determine the priority of each frame. Factory Default Enable CoS Mapping Setting Low/Normal/ Medium/High Description Factory This maps different CoS values to 4 different egress 0: Low queues.
PT-7728 User’s Manual Setting Low/Normal/ Medium/High Featured Functions 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 VLANs: Tagged and Untagged Membership The PT-7728 supports 802.1Q VLAN tagging, a system that allows traffic for multiple VLANs to be carried on a single physical (backbone, trunk) link. 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.
PT-7728 User’s Manual Featured Functions 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 Featured Functions Configuring Virtual LAN VLAN Settings To configure 802.1Q VLAN on the PT-7728, use the VLAN Setting page to configure the ports.

Forbidden VLAN List Setting Description VID range from 1 This field will be active only when selecting the Trunk to 4094 port type. Set the VLAN IDs that will not be supported by this trunk port.
PT-7728 User’s Manual Featured Functions Benefits of Multicast The benefits of using IP multicast are that it: y y y y Uses the most efficient, sensible method to deliver the same information to many receivers with only one transmission. Reduces the load on the source (for example, a server) since it will not need to produce several copies of the same data. Makes efficient use of network bandwidth and scales well as the number of multicast group members increases.

PT-7728 User’s Manual Featured Functions Event Setup 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 PT-7728 supports two relay outputs. You can configure which relay output is related to which events. This helps administrators identify the importance of the different events.
PT-7728 User’s Manual Featured Functions Override relay alarm settings Click the checkbox to override the relay warning setting temporarily. Releasing the relay output will allow administrators to fix any problems with the warning condition. Warning List Use this table to see if any relay alarms have been issued.
PT-7728 User’s Manual Featured Functions STEP 1—Set up the connected devices Set up those Ethernet-enabled devices connected to PT-7728 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.
PT-7728 User’s Manual Featured Functions Desired IP Address Setting IP Address Description Set the desired IP of connected devices. Factory Default None Using Diagnosis The PT-7728 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.
PT-7728 User’s Manual Featured Functions Ping 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 PT-7728 itself. In this way, the user can essentially sit on top of PT-7728 and send ping commands out through its ports.
