EDS-508A/505A Series User’s Manual Featured Functions The Communication Redundancy function allows the user to set up redundant loops in the network to provide a backup data transmission route in the event that a cable is inadvertently disconnected or damaged. This feature is particularly important for industrial applications, since it could take several minutes to locate the disconnected or severed cable.
EDS-508A/505A Series User’s Manual Featured Functions The Turbo Ring and Turbo Ring V2 protocols identify one switch as the master of the network, and then automatically block packets from traveling through any of the network’s redundant loops. In the event that one branch of the ring gets disconnected from the rest of the network, the protocol automatically readjusts the ring so that the part of the network that was disconnected can reestablish contact with the rest of the network.
EDS-508A/505A Series User’s Manual Featured Functions “Turbo Ring” rings with an even number of EDS units If there are 2N EDS units (an even number) in the “Turbo Ring” ring, then the backup segment is one of the two segments connected to the (N+1)st EDS (i.e., the EDS unit directly opposite the master).
EDS-508A/505A Series User’s Manual Featured Functions For a “Turbo Ring V2” ring, the backup segment is the segment connected to the 2nd redundant port on the master. Master See Configuring “Turbo Ring V2” in the Configuring “Turbo Ring” and “Turbo Ring V2” section below. Ring Coupling Configuration For some systems, it may not be convenient to connect all devices in the system to create one BIG redundant ring, since some devices could be located in a remote area.

Factory Default EDS-505A: port 4 EDS-508A: port 7 EDS-505A: port 5 EDS-508A: port 8 The STP/RSTP Concept Spanning Tree Protocol (STP) was designed to help reduce link failures in a network, and provide protection from loops.
EDS-508A/505A Series User’s Manual Featured Functions STP (802.1D) is a bridge-based system that is used to implement parallel paths for network traffic. STP uses a loop-detection process to: 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.
EDS-508A/505A Series 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. LAN 1 Bridge B Bridge A LAN 2 Bridge C LAN 3 STP will determine 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.
EDS-508A/505A Series User’s Manual Featured Functions STP Calculation The first step of the STP process is to perform calculations. During this stage, each bridge on the network transmits BPDUs. The following items will be calculated: Which bridge should be the Root Bridge. The Root Bridge is the central reference point from which the network is configured. The Root Path Costs for each bridge. This is the cost of the paths from each bridge to the Root Bridge. The identity of each bridge’s Root Port.
EDS-508A/505A Series User’s Manual Featured Functions STP Example The LAN shown in the following figure has three segments, with adjacent segments connected using two possible links. The various STP factors, such as Cost, Root Port, Designated Bridge Port, and Blocked Port are shown in the figure.
EDS-508A/505A Series 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.
EDS-508A/505A Series 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 follows. At the top of this page, the user can check the “Current Status” of this function. For RSTP, you will see: Now Active: This will show which communication protocol is being used—Turbo Ring, RSTP, or neither. Root/Not Root This field will appear only when selected to operate in RSTP mode.
EDS-508A/505A Series User’s Manual Featured Functions Forwarding Delay Setting Numerical value input by user Description The amount of time this device waits before checking to see if it should change to a different state. Factory Default 15 (sec.) Description The root of the Spanning Tree topology periodically sends out a “hello” message to other devices on the network to check if the topology is healthy. The “hello time” is the amount of time the root waits between sending hello messages.
EDS-508A/505A Series User’s Manual Featured Functions Configuration Limits of RSTP/STP The Spanning Tree Algorithm places limits on three of the configuration items described previously: [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. 4]: 2 * (Hello Time + 1 sec) ≦ Max.
EDS-508A/505A Series User’s Manual Featured Functions How Traffic Prioritization Works Traffic prioritization uses the four traffic queues that are present in your EDS 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. EDS traffic prioritization depends on two industry-standard methods: IEEE 802.1D—a layer 2 marking scheme. Differentiated Services (DiffServ)—a layer 3 marking scheme.
EDS-508A/505A Series User’s Manual Featured Functions Advantages of DiffServ over IEEE 802.1D are: Configure how you want your switch to treat selected applications and types of traffic by assigning various grades of network service to them. No extra tags are required in the packet. DSCP uses the IP header of a packet and therefore priority is preserved across the Internet.
EDS-508A/505A Series 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 EDS 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 EDS’s QoS capability improves your industrial network’s performance and determinism for mission critical applications.

EDS-508A/505A Series User’s Manual Featured Functions Managing a VLAN A new or initialized EDS contains a single VLAN—the Default VLAN. This VLAN has the following definition: VLAN Name—Management VLAN 802.1Q VLAN ID—1 (if tagging is required) All the ports are initially placed on this VLAN, and it is the only VLAN that allows you to access the management software of the EDS over the network.
EDS-508A/505A Series User’s Manual Featured Functions The following section illustrates how to use these ports to set up different applications.
EDS-508A/505A Series User’s Manual Featured Functions After proper configuration: Packets from device A will travel through “Trunk Port 3” with tagged VID 5. Switch B will recognize its VLAN, pass it to port 6, and then remove tags received successfully by device G, and vice versa. Packets from device B and C will travel through “Trunk Port 3” with tagged VID 2. Switch B recognizes its VLAN, passes it to port 4, and then removes tags received successfully by device F, and vice versa.

EDS-508A/505A Series User’s Manual NOTE Featured Functions 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. This section explains multicasts, multicast filtering, and how multicast filtering can be implemented on your EDS. The Concept of Multicast Filtering What is an IP Multicast? A multicast is a packet sent by one host to multiple hosts.
EDS-508A/505A Series User’s Manual Featured Functions Network without multicast filtering Group 1 Multicast Stream Group 2 Multicast Stream Serial ports Console IGMP Group2 LAN 1 IGMP Group1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 IGMP Group2 IGMP Group1 All hosts receive the multicast traffic, even if they don’t need it.
EDS-508A/505A Series User’s Manual Featured Functions Multicast Filtering and Moxa EtherDevice Switch The EDS 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.
