  • Page 31: Configuring Snmp

    Configuring SNMP The PT-7728 supports SNMP V1, V2c, and V3. SNMP V1 and SNMP V2c use a community string match for authentication, which means that SNMP servers access all objects with read-only or read/write permissions using the community strings public and private by default. SNMP V3 requires that you select an authentication level of MD5 or SHA, and is the most secure protocol.

  • Page 35: Snmp Inform Mode

    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 36: The Turbo Ring Concept

    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 37 PT-7728 User’s Manual Featured Functions Turbo Ring with even number of switches If the number of Ethernet switches in the Turbo Master 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 38 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.

  • Page 39: Configuring Turbo Ring, Turbo Ring V2, And Turbo Chain

    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.

  • Page 40: Configuring Turbo Ring

  • Page 45: The Turbo Chain Concept

    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.

The “Ports Status” indicators show Forwarding for normal transmission, Blocked if this port is connected to the Tail port as a backup path and the path is blocked, and Link down if there is no connection.

  • Page 47: 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 48: What Is Stp

    It defaults to sending 802.1D style BPDUs if packets with this format are received. 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.

  • Page 49: How Stp Works

    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.
  • Page 50 PT-7728 User’s Manual 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.

  • Page 51: Stp Example

    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.

  • Page 52: Configuring Stp/Rstp

    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.
  • Page 53 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 57: Configuring Traffic Prioritization

    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.

  • Page 59: 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 60: 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 61: Communication Between Vlans

    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 62: Sample Applications Of Vlans Using Pt-7728

    PT-7728 User’s Manual Featured Functions Sample Applications of VLANs using PT-7728 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.

    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.

  • Page 67: Igmp Multicast Filtering

    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 68: 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.

    For example, so-called “broadcast storms” could be caused by an incorrectly configured topology, or a malfunctioning device. The PT-7728 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.
