    This is a particularly important feature for industrial applications, since it could take several minutes to locate the disconnected or severed cable. For example, if the PT-7728 is used as a key communications component of a production line, several minutes of downtime can result in a big loss in production and revenue.

  • Page 32: The Turbo Ring Concept

    PT-7728 User’s Manual Featured Functions NOTE Most managed switches by Moxa support two proprietary Turbo Ring protocols: 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.
  • Page 33 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).
  • Page 34 PT-7728 User’s Manual Featured Functions Determining the Redundant Path for Turbo Ring V2 For Turbo Ring V2, the backup segment is the Master segment connected to the 2nd redundant port on the master. Please refer to Configuring Turbo Ring V2 later in this chapter.

  • Page 41: The Stp/Rstp Concept

    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.
  • Page 42 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.

  • Page 43: How Stp Works

    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: Communication must be established between all bridges.

  • Page 44: Stp Example

    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.

  • Page 45: Using Stp On A Network With Multiple Vlans

    PT-7728 User’s Manual 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.

  • Page 46: Configuring Stp/Rstp

    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).
  • Page 47 This specifies the amount of time to wait for a user "hello" message from the root before the PT-7728 will reconfigure itself as a root. When two or more devices on the network are recognized as a root, the devices will renegotiate to set up a new Spanning Tree topology.

  • Page 48: Using Traffic Prioritization

    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 PT-7728 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.

  • Page 49: How Traffic Prioritization Works

    How Traffic Prioritization Works Traffic prioritization uses the four traffic queues that are present in your PT-7728 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.
  • Page 50 3 TOS enabled prioritization scheme. Traffic Prioritization The PT-7728 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 traffic is classified based upon the IEEE 802.1D frame and is assigned to the appropriate priority...

  • Page 53: Using Virtual Lan

    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.

  • Page 54: Benefits Of Vlans

    In a single VLAN defined on the PT-7728 In several VLANs simultaneously using 802.1Q tagging The standard requires that you define the 802.1Q VLAN ID about each VLAN on your PT-7728 before the switch can use it to forward traffic: Managing a VLAN A new or initialized PT-7728 contains a single VLAN—the Default VLAN.

  • Page 55: Sample Applications Of Vlans Using Pt-7728

    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.
  • Page 56 PT-7728 User’s Manual Featured Functions In this application, 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.

  • Page 59: Benefits Of Multicast

    PT-7728 User’s Manual Featured Functions Benefits of Multicast The benefits of using IP multicast are that it: 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.
  • Page 60 Query Mode Query mode allows the PT-7728 to work as the Querier if it has the lowest IP address on the subnetwork to which it belongs. IGMP querying is enabled by default on the PT-7728 to help prevent interoperability issues with some multicast routers that may not follow the lowest IP address election method.

  • Page 61: Configuring Igmp Snooping

    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.
