    5-minute recovery time for commercial switches—decreasing the possible loss caused by network failure. A set of DIP Switches located on EDS-408A/405A’s outer casing can be easily used to configure the Turbo Ring settings in only a few seconds. Some users may wish to disable the Turbo Ring DIP Switches to avoid accidental changes to the configuration.
  • Page 25 DIP Switch first. NOTE If you do not enable any of the EDS-408A/405A switches to be the Ring Master, the Turbo Ring protocol will automatically choose the EDS-408A/405A with the smallest MAC address range to be the Ring Master. If you accidentally enable more than one EDS-408A/405A to be the Ring Master, these EDS-408A/405A switches will auto-negotiate to determine which one will be the Ring Master.

    LAN”). System File Update—By Remote TFTP MOXA EtherDevice Switch supports saving your configuration file to a remote TFTP server or local host to allow other EtherDevice Switches to use the same configuration at a later time, or saving the Log file for future reference. Loading pre-saved firmware or a configuration file from the TFTP server or local host is also supported for easy upgrading or configuration of the EtherDevice Switch.

    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 MOXA EtherDevice Switch is used as a key communications component of a production line, several minutes of downtime could cause a big loss in production and revenue.
  • Page 32 EDS-408A/405A Series User’s Manual Featured Functions Initial Setup 1. Select any two ports as redundant ports. 2. Connect the redundant ports to form the Turbo Ring The user does not need to set the master to use Turbo Ring. Master is only needed to identify which segment acts as the backup path.

  • Page 36: The Stp/Rstp Concept

    Networks that have a complicated architecture are prone to broadcast storms caused by unintended loops in the network. MOXA EtherDevice Switch’s STP feature is disabled by default. To be completely effective, you must enable RSTP/STP on every EDS connected to your network.
  • Page 37 EDS-408A/405A Series User’s Manual Featured Functions Locate and then disable less efficient paths (i.e., paths that have a lower bandwidth). Enable one of the less efficient paths if the most efficient path fails. The figure below shows a network made up of three LANs separated by three bridges. Each segment uses at most two paths to communicate with the other segments.

  • Page 38: How Stp Works

    EDS-408A/405A Series User’s Manual Featured Functions LAN 1 Bridge B LAN 2 Bridge A Bridge C LAN 3 STP determines which path between each bridged segment is most efficient, and then assigns a specific reference point on the network. When the most efficient path has been identified, the other paths are blocked.

Age ≦ 2 * (Forwarding Delay – 1 sec) MOXA EtherDevice Switch’s firmware will alert you immediately if any of these restrictions are violated. For example, setting Hello Time = 5 sec, Max.

  • Page 44: 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. MOXA EtherDevice Switch can inspect both IEEE 802.1p/1Q layer 2 QoS tags, and even layer 3 TOS information to provide consistent classification of the entire network.
  • Page 45 EDS-408A/405A Series User’s Manual Featured Functions The IEEE Std 802.1D, 1998 Edition priority marking scheme assigns an IEEE 802.1p priority level between 0 and 7 to each frame. This determines the level of service that 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.

  • Page 46: Configuring Traffic Prioritization

    This method always gives precedence to high priority over low-priority. Configuring Traffic Prioritization QoS Classification MOXA EtherDevice Switch supports inspection of layer 3 TOS and/or layer 2 QoS tag information to determine how to classify traffic packets. (NOTE: The user interface for EDS-408A shows 8 ports.) 3-31...
  • Page 47 Queuing Mechanism Setting Description Factory Default EDS-408A/405A has 4 priority queues. In the weight fair scheme, an 8, 4, 2, 1 weighting is applied to the four priorities.

  • Page 49: Using Virtual Lan

    EDS-408A/405A Series User’s Manual Featured Functions Using Virtual LAN Setting up Virtual LANs (VLANs) on your EDS 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 50: Using Virtual Lan

    Using Virtual LAN Port-based VLANs and MOXA EtherDevice Switch EDS-408A/405A supports Port-based VLAN. When using this function, you must first define which ports should join the VLAN. Once set, devices can be moved around the network without affecting to which VLAN the device is connected.

  • Page 51: Using Rate Limiting

    A single device should not be allowed to occupy unlimited bandwidth, especially when the device malfunctions. For example, broadcast storms could be caused by an incorrect topology or malfunctioning device. The EDS-408A/405A series not only prevents broadcast storms, but can also configure the ingress rate of unicast/multicast/broadcast packets, giving administrators full control of the limited bandwidth, and preventing unpredictable faults before they occur.
  • Page 52 EDS-408A/405A Series User’s Manual Featured Functions Policy Setting Description Factory Default Selecting this option prohibits all traffic of Limit All broadcast, multicast, and unicast packets that exceed the rate set in the following “Rate” field. Selecting this option prohibits all traffic of...

  • Page 53: Using Auto Warning

    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. MOXA EtherDevice Switch supports different approaches such as email and relay output to warn engineers automatically.
  • Page 54 EDS-408A/405A Series User’s Manual Featured Functions 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.
