Configuration Reminders
In this section, several examples will be used to remind users when configuring the settings for Moxa’s switch.
A: About Mandatory Parameters
1. The items with asterisks mean they are mandatory parameters that must be provided. In the figure above, the parameters for VLAN, Version, and Query Interval all need to be provided, or it will not be created or applied.
2. If the item is marked with red it means this item has been skipped. You need to fill in the parameters or you cannot apply or create the function.
In addition, some parameter values will be limited to a specific range. If the values exceed the range, it cannot be applied or created.
B: Configurations before Enable/Disable
In another situation, some settings can be configured first, but remain disabled. Users can decide to enable them when necessary without configuring the same settings again. This is particularly convenient and userfriendly when configuring various settings. For example, on the DHCP Server configuration page, users can configure the DHCP settings first, but later select to disable the DHCP settings in the General tab. When users decide to enable the DHCP settings, they only need to select Enable in General settings, so that the DHCP settings (either MAC-based IP Assignment or Port-based IP Assignment as shown as an example in the following figure) can be enabled at the same time.

2. Getting Started
In this chapter, we explain how to log in a Moxa’s switch for the first time. There are three ways to access the Moxa switch’s configuration settings: RS-232 console, telnet (disabled by default) or web-based interface.
Log in by Web Interface
You can directly connect Moxa’s switch to your computer with a standard network cable or install your computer at the same intranet as your switch. Then you need to configure your computer’s network setting. The default IP address for the Moxa’s switch is: 192.168.127.253 For example, you can configure the computer’s IP setting as 192.168.127.99, and the subnet mask as 255.255.255.0.

Click OK when finished.

NOTE
For network security consideration, all HTTP connections will be automatically redirected to HTTPS connections. The web browser will display a warning message if the device uses a certificate which isn’t signed by the certification authority. You may add an exception rule for the certificate in the web browser to continue. We recommend using a certificate signed by a certification authority for security reasons. Refer to “Security > Device Security > SSH & SSL > SSL” for the configuration steps.
The default username and password are:
Username: admin Password: moxa

Link Aggregation

Link Aggregation (Port Channel) Overview
Link Aggregation helps balance, optimize, and facilitate the switch’s throughput. This method can combine multiple network communications in parallel to maximize data throughput, increasing data communication efficiency for each port. In addition, it also acts as a useful method for network redundancy when a link fails. In general, Link Aggregation supports combining multiple physical switch ports into a single, efficient bandwidth data communication route. This can improve network load sharing and increase network reliability.

Moxa’s Managed Switch Next Generation OS (v3.x) User Manual

Static Trunk
For some networking applications, a situation can arise where traffic from multiple ports is required to be filtered through one port. For example, if there are 30 UHD IP surveillance cameras deployed and connected in a ring, the traffic can reach up to 1 Gbps, causing a surge in traffic that can increase network loading by up to 50%. Hence, the uplink port needs to use the static trunk function to provide more bandwidth and redundancy protection.
LACP

PoE
PoE Overview
Power over Ethernet (PoE) has become increasingly popular, due in large part to the reliability provided by PoE Ethernet switches that supply the power to Powered Devices (PD) when AC power is not available or is too expensive to provide locally. Power over Ethernet can be used with the following types of devices: · Surveillance cameras · Security I/O sensors · Industrial wireless access points · Emergency IP phones Recently, more data, video, voice, service, and control packets are converging on one network. Moxa’s PoE switches are equipped with many advanced PoE management functions, providing critical security systems with a convenient and reliable Ethernet network. Moreover, Moxa’s advanced PoE switches support the high power PoE+ standard, PD failure check, legacy PD detection, and auto power cutting.

VLAN
This section includes IEEE802.1Q configurations.

Moxa’s Managed Switch Next Generation OS (v3.x) User Manual

IEEE 802.1Q Overview
The IEEE 802.1Q is a network communication protocol that falls under the IEEE 802.1 standard regulation, allowing various segments to use a physical network at the same time to block broadcast packets by different segmentations. It specifies the VLAN tagging for Ethernet frames on switches that can control the path process.
How A VLAN Works
What is a VLAN?
A VLAN is a group of devices that can be located anywhere on a network, but which communicate as if they are on the same physical segment. With VLANs, you can segment your network without being restricted by physical connections–a limitation of traditional network design. With VLANs you can segment your network into:
· Departmental groups–You could have one VLAN for the marketing department, another for the finance department, and another for the product development department.
· Hierarchical groups–You could have one VLAN for directors, another for managers, and another for general staff.
· Usage groups–You could have one VLAN for email users and another for multimedia users.

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:
· VLANs ease the relocation of devices on networks: With traditional networks, network administrators spend much of their time dealing with changes. If users move to a different subnetwork, the addresses of each host must be updated manually. With a VLAN setup, if a host originally on the Marketing VLAN is moved to a port on another part of the network, and retains its original subnet membership, you only need to specify that the new port is on the Marketing VLAN. You do not need to do any re-cabling.
· VLANs provide extra security: Devices within each VLAN can only communicate with other devices on the same VLAN. If a device on the Marketing VLAN needs to communicate with devices on the Finance VLAN, the traffic must pass through a routing device or Layer 3 switch.
· VLANs help control traffic: With traditional networks, congestion can be caused by broadcast traffic that is directed to all network devices, regardless of whether or not they need it. VLANs increase the efficiency of your network because each VLAN can be set up to contain only those devices that need to communicate with each other.

Moxa’s Managed Switch Next Generation OS (v3.x) User Manual

VLANs and the Moxa switch
Your Moxa switch includes support for VLANs using IEEE Std 802.1Q-2005. This standard allows traffic from multiple VLANs to be carried across one physical link. The IEEE Std 802.1Q-2005 standard allows each port on your Moxa switch to be placed as follows:
· On a single VLAN defined in the switch · On several VLANs simultaneously using 802.1Q tagging
The standard requires that you define the 802.1Q VLAN ID for each VLAN on your Moxa switch before the switch can use it to forward traffic:
Managing a VLAN
A new or initialized Moxa switch contains a single VLAN–the Default VLAN. This VLAN has the following definition:
· Management VLAN ID 1 can be changed · 802.1Q VLAN default ID 1 cannot be deleted
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 Moxa switch over the network.
Communication Between VLANs
If devices connected to a VLAN need to communicate with devices on a different VLAN, a router or Layer 3 switching device with connections to both VLANs need to be installed. Communication between VLANs can only take place if they are all connected to a routing or Layer 3 switching device.
VLANs: Tagged and Untagged Membership
Moxa’s switch supports 802.1Q VLAN tagging, a system that allows traffic for multiple VLANs to be carried on a single physical link (backbone, trunk). When setting up VLANs you need to understand when to use untagged or 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, a tagged membership must be defined.
A typical host (e.g., clients) will be an untagged member of one VLAN, defined as an Access Port in a Moxa switch, while an inter-switch connection will be a tagged member of all VLANs, defined as a Trunk Port in a Moxa switch.
The IEEE Std 802.1Q-2005 defines how VLANs operate within an open packet- switched network. An 802.1Q compliant packet carries additional information that allows a switch to determine which VLAN the port belongs to. If a frame is carrying the additional information, it is known as a tagged frame.
To carry multiple VLANs across a single physical link (backbone, trunk), each packet must be tagged with a VLAN identifier so that the switches can identify which packets belong to which VLAN. To communicate between VLANs, a router must be used.
Moxa’s switch supports three types of VLAN port settings:
· Access Port: The port connects to a single device that is not tagged. The user must define the default port PVID that assigns which VLAN the device belongs to. Once the ingress packet of this Access Port egresses to another Trunk Port (the port needs all packets to carry tag information), the switch will insert this PVID into this packet so the next 802.1Q VLAN switch can recognize it.
· Trunk Port: The port connects to a LAN that consists of untagged devices and tagged devices. In general, the traffic of the Trunk Port must have a Tag. Users can also assign a PVID to a Trunk Port. The untagged packet on the Trunk Port will be assigned the default port PVID as its VID.
· Hybrid Port: The port is similar to a Trunk port, except users can explicitly assign tags to be removed from egress packets.

Moxa’s Managed Switch Next Generation OS (v3.x) User Manual

The following section illustrates how to use these ports to set up different applications.

In this application:
· Port 1 connects a single untagged device and assigns it to VLAN 5; it should be configured as an 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. It should be configured as a Hybrid Port with PVID 2 for untagged device and Fixed VLAN (Tagged) with 3 and 4 for tagged device. Since each port can only have one unique PVID, all untagged devices on the same port must belong to the same VLAN.
· Port 3 connects with another switch. It should be configured as a Trunk Port. GVRP protocol will be used through the Trunk Port.
· Port 4 connects a single untagged device and assigns it to VLAN 2; it should be configured as an Access Port with PVID 2.
· Port 5 connects a single untagged device and assigns it to VLAN 3; it should be configured as an Access Port with PVID 3.
· Port 6 connect a single untagged device and assigns it to VLAN 5; it should be configured as an Access Port with PVID 5.
· Port 7 connects a single untagged device and assigns it to VLAN 4; it should be configured as an Access Port with PVID 4.
After the application is properly configured:
· 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 Devices B and C will travel through Hybrid Port 2 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.
· Packets from Device D will travel through Trunk Port 3 with tagged VID 3. Switch B will recognize its VLAN, pass to port 5, and then remove tags received successfully by Device H. Packets from Device H will travel through Trunk Port 3 with PVID 3. Switch A will recognize its VLAN and pass it to port 2, but will not remove tags received successfully by Device D.
· Packets from Device E will travel through Trunk Port 3 with tagged VID 4. Switch B will recognize its VLAN, pass it to port 7, and then remove tags received successfully by Device I. Packets from Device I will travel through Trunk Port 3 with tagged VID 4. Switch A will recognize its VLAN and pass it to port 2, but will not remove tags received successfully by Device E.

QoS
This section describes how QoS works and how to configure the settings.

QoS Overview
The switch’s traffic prioritization capability provides Quality of Service (QoS) to your network by making data delivery more reliable. You can prioritize traffic on your network to ensure that high priority data is transmitted with minimum delay. Traffic can be controlled by a set of rules to obtain the required 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 switch can inspect both IEEE 802.1p/1Q layer 2 CoS (Class of Service) tags, and even layer 3 DSCP (Differentiated Services Code Point) information to provide consistent classification of the entire network. The switch’s QoS capability improves the performance and determinism of industrial networks for mission-critical applications.
The Traffic Prioritization Concept
Traffic prioritization allows you to prioritize data so that time-sensitive and system-critical data can be transferred smoothly and with minimal delay over a network. The benefits of using traffic prioritization are:
· Improve network performance by controlling a wide variety of traffic and by managing congestion. · Assign priorities to different categories of traffic. For example, set higher priorities for time-critical or
mission-critical applications. · Provide predictable throughput for multimedia applications, such as video conferencing or voice over IP,
and minimize traffic delay and jitter. · Optimize the network utilization depending on application usage and usage needs. Hence, asset owners
do not always need to expand their backbone bandwidth as the amount of traffic increases.
Traffic prioritization uses eight traffic queues to ensure that higher priority traffic can be forwarded separately from lower priority traffic, which guarantees Quality of Service (QoS) to your network.

Moxa’s Managed Switch Next Generation OS (v3.x) User Manual

Moxa switch traffic prioritization is based on two standards:

· IEEE 802.1p–a layer 2 QoS marking scheme · Differentiated Services (DiffServ)–a layer 3 QoS marking scheme.

IEEE 802.1p Class of Service

The IEEE Std 802.1D 2005 Edition marking scheme, which is an enhancement to IEEE Std 802.1D, enables Quality of Service on the LAN. Traffic service levels are defined in the IEEE 802.1Q 4-byte tag, which is used to carry VLAN identification as well as IEEE 802.1p priority information. The IEEE 802.1p occupying 3 bits of the tag follows the destination MAC address and Source MAC address.

The IEEE Std 802.1D 2005 Edition priority marking scheme assigns an IEEE 802.1p priority level between 0 and 7 to each frame, which specifies the level of service that the associated packets shall be handled. The table below shows an example of how different traffic types can be mapped to the eight IEEE 802.1p priority levels.

IEEE 802.1p Priority Level 0 1 2 3 4 5 6 7

IEEE 802.1D Traffic Type Best Effort Background (lowest priority) Reserved Excellent Effort (business critical) Controlled Load (streaming multimedia) Video (interactive media) Voice (interactive voice) Network Control Reserved traffic

Even though the IEEE 802.1p standard is the most widely used prioritization scheme for LAN environments, it still has some restrictions:

· It requires an additional 4-byte tag in the frame, which is normally optional for Ethernet networks. Without this tag, the scheme cannot work.
· The tag is part of the IEEE 802.1Q header, so to implement QoS at layer 2, the entire network must implement IEEE 802.1Q VLAN tagging.
· It is only supported within a LAN and does not cross the WAN boundaries, since the IEEE 802.1Q tags will be removed when the packets pass through a router.

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 specify the packet priority. DSCP is an advanced intelligent method of traffic marking that allows you to choose how your network prioritizes different types of traffic. The DSCP field can be set from 0 to 63 to map to user-defined service levels, enabling users to regulate and categorize traffic by applications with different service levels.

The advantages of DiffServ over IEEE 802.1Q are as follows:

· You can prioritize and assign different traffic with appropriate latency, throughput, or reliability by each port.
· No extra tags are required.
· The DSCP priority tags are carried in the IP header, which can pass the WAN boundaries and through the Internet.
· DSCP is backwards compatible with IPv4 ToS (Type of Service), which allows operation with legacy devices that use IPv4 layer 3.

Moxa’s Managed Switch Next Generation OS (v3.x) User Manual

Traffic Prioritization
Moxa switches classify traffic based on layer 2 of the OSI 7 layer model, and the switch prioritizes outbound traffic according to the priority information defined in the received packet. Incoming traffic is classified based upon the IEEE 802.1p service level field and is assigned to the appropriate egress priority queue. The traffic flow through the switch is as follows:
· A packet received by the Moxa switch may or may not have an 802.1p tag associated with it. If it does not, then it is given a default CoS value (according to the port settings in the classification section). Alternatively, the packet might be marked with a new 802.1p value, which will result in all knowledge of the previous 802.1p tag being lost.
· Each egress queue has associated 802.1p priority levels, and can be defined by users, the packet will be placed in the appropriate priority queue. When the packet reaches the head of its queue and is about to be transmitted, the device determines whether or not the egress port belongs to the VLAN group. If it is, then the new 802.1p tag is used in the extended 802.1D header.
Traffic Queues
The hardware of Moxa switches has multiple traffic queues that allow packet prioritization to occur. Higher priority traffic can pass through the Moxa switch without being delayed by lower priority traffic. As each packet arrives in the Moxa switch, it undergoes ingress processing (which includes classification, marking/re-marking), and is then sorted into the appropriate queue. The switch then forwards packets from each queue.
Moxa switches support two different queuing mechanisms:
· Weight Fair: This method services all the traffic queues, giving priority to the higher priority queues. Under most circumstances, the Weight Fair method gives high priority precedence over low priority, but in the event that high priority traffic does not reach the link capacity, lower priority traffic is not blocked.
· Strict: This method services high traffic queues first; low priority queues are delayed until no more high priority data needs to be sent. The Strict method always gives precedence to high priority over low priority.

Scheduler

Scheduler Overview
Scheduler is an arbiter in switch forwarding path to prioritize traffic flows by users’ defined criteria. This essentially enhances data transmission efficiency and guarantees that critical packets can be transmitted earlier. Moxa’s switches support two scheduling algorithms: Strict Priority and Weighted Round Robin.

Moxa’s Managed Switch Next Generation OS (v3.x) User Manual

Strict Priority
The Strict Priority type allows users to determine to transmit packets in the highest priority queue first, while packets with lower priority will be transmitted later. This guarantees that traffic with the highest level of priority for data transmission will go first.
Weighted Round Robin
The Weighted Round Robin type allows users to give priority to specific packets in the higher weighted queue to ensure those packets will be sent first. Moxa switches now have 8 queues, and the weights from highest to lowest are 8:8:4:4:2:2:1:1.

Multicast
Multicast filtering improves the performance of networks that carry multicast traffic. This section will explain the Layer 2 multicast settings, such as IGMP Snooping, GMRP, and Static Multicast.
IGMP Snooping IGMP Snooping Overview
IGMP stands for Internet Group Management Protocol, which is a network communication protocol that hosts nearby routers on networks to construct multicast group memberships. IGMP snooping allows a network switch to listen in on the IGMP conversation between hosts and routers. By listening to these conversations, the switch maintains an association mapping table between port(s) and multicast group.
How IGMP Snooping Works
A switch will, by default, flood multicast traffic to all the other ports, aside ingress, in a broadcast domain (or the VLAN equivalent). Multicast can cause unnecessary loading for host devices by requiring them to process packets they have not solicited. IGMP snooping is designed to prevent hosts on a local network from receiving traffic for a multicast group they have not explicitly joined. It provides switches with a mechanism to forward multicast traffic to specific ports that receive IGMP hosts. Hence, IGMP snooping can utilize the network bandwidth more efficiently.

GMRP
GMRP stands for GARP Multicast Registration Protocol, which is a Generic Attribute Registration Protocol (GARP) application that can be used to prevent multicast from data flooding. Both GMRP and GARP are defined by the IEEE 802.1P, and widely used as a standard protocol in various industrial-related applications. GMRP allows bridges and the devices at the edge of the network to perform a dynamic group membership information registration with the MAC bridges connected to the same LAN section. The information can be transmitted among all bridges in the Bridge LAN that is implemented with extended filtering features. To operate GMRP, the GARP service must be established first.

Network Redundancy
Setting up the Redundancy Protocol on your network helps protect critical links against failure, protects against network loops, and keeps network downtime to a minimum.
The Redundancy Protocol allows you to set up redundant paths on the network to provide a backup data transmission route in the event that a cable or one of the switches is inadvertently disconnected or damaged. This is a particularly important feature for industrial applications, since it can take several minutes to address the link down port or failed switch. For example, if a Moxa switch is used as a key communications device for a production line, several minutes of downtime can cause a big loss in production and revenue. Moxa switches support the following Redundancy Protocol functions:
· Spanning Tree · Turbo Ring V2 · Turbo Chain · Dual Homing

Spanning Tree Spanning Tree Overview
Spanning Tree Protocol (STP) was designed to help construct a loop-free logical typology on an Ethernet network, and provide an automatic means of avoiding any network loops. This is particularly important for networks that have a complicated architecture, since unintended loops in the network can cause broadcast storms. Moxa switches’ STP feature is disabled by default. To be completely effective, you must enable STP/RSTP on every Moxa switch connected to your network. 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 (e.g., paths that have lower bandwidth). · Enable one of the less efficient paths if a more efficient path fails.
How STP Works
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. Since this configuration can give rise to loops, the network will overload if STP is not enabled.

Moxa’s Managed Switch Next Generation OS (v3.x) User Manual

If STP is enabled, it will detect duplicate paths or block one of the paths from forwarding traffic. In the following example, STP determined that traffic from segment 2 to segment 1 flows through switches C and A since this path is in a forwarding state and is processing BPDUs. However, switch B on segment 1 is in a blocking state.
What happens if a link failure is detected? As shown in the figure below, the STP will change the blocking state to a forwarding state so that traffic from segment 2 flows through switch B to segment 1 through a redundant path.

STP will determine which path between each segment is most efficient, and then assign a specific reference point on the network. When the most efficient path has been identified, the other paths are blocked. In the previous three figures, STP first determined that the path through switch C was the most efficient, and as a result, blocked the path through switch B. After the failure of switch C, STP re-evaluated the situation and opened the path through switch B.
Difference Between STP and RSTP
RSTP is similar to STP but includes additional information in the BPDUs that allow each bridge to confirm that it has taken action to prevent loops from forming when it decides to enable a link to a neighboring bridge. Adjacent bridges connected via point-to-point links will be able to enable 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 to carry out automatic configuration and restore a link faster than STP.
STP and RSTP spanning tree protocols operate without regard to a network’s VLAN configuration and maintain one common spanning tree throughout a bridged network. Thus, these protocols map one loopfree, logical topology on a given physical topology.

BPDU Overview
BDPUs (Bridge Protocol Data Units) are the network communication frames used in the STP (Spanning Tree Protocol). When two switches exchange messages, BDPUs are used to calculate the STP topology, and determine the network communication route. A BDPU filter is often used to screen sending or receiving BPDUs on a specific port of the switch.
BPDU Guard
BDPU Guard is a protection mechanism that prevents a port from receiving BPDUs. When an RSTP-enabled port receives BPDUs, it will automatically be in the error-disable state, which means the port will in turn switch to Block state. When STP is enabled, all ports are involved in the STP domain, sending and receiving BPDUs. However, when BPDU Guard is enabled, all ports will not receive or send any BPDUs, as all computers and unmanaged switches do not support STP. When BPDU Guard is enabled, all communications will be treated as error-disabled, and the related ports will be blocked, therefore no more data will be sent or received, protecting the network from a loop chain.
Root Guard
Root Guard prevents a designated port role from changing to root port role on reception of superior information.
Loop Guard
Loop Guard prevents temporary loops in a network caused by non-designated ports changing to the spanning-tree forwarding state due to a link failure in the topology.
BPDU Filter
BPDU Filter prevents a port from sending and processing BPDUs. A BPDU filter enabled port cannot transmit any BPDUs and drop all received BPDU either.

Turbo Ring v2 Turbo Ring v2 Overview
Moxa Turbo Ring is a proprietary self-healing technology that enables fast fault recovery of under 20 ms for Fast Ethernet, and 50 ms for Gigabit Ethernet. Turbo Ring supports two topology expansions–ring coupling and dual- ring–to reduce redundant network cabling and network planning costs and to ensure high reliability of your industrial network applications. The Turbo Ring v2 protocols identify one switch as the master of the network, and then automatically block one port beside master on the ring (red line) to avoid 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.
How Turbo Ring v2 Works
Turbo Ring v2 is an advanced technology for network redundancy, which ensures recovery times of less than 20 ms for Fast Ethernet, and 50 ms for Gigabit Ethernet when the network is down. In addition, it allows more switches within the network rings. Users can select different network typologies for Turbo Ring redundancy to allow more network reliability and reduce cabling costs. Below are three examples of how Turbo Ring v2 works.
Ring Coupling
Ring Coupling helps users separate distributed devices into different smaller redundant rings, but in such a way that the smaller rings at different remote sites will be able to communicate with each other. This is useful for applications where some devices are located at remote sites.

Moxa’s Managed Switch Next Generation OS (v3.x) User Manual

105

Dual-Ring
Dual-Ring adds reliability by using a single Moxa switch to connect two separate rings for applications that present cabling difficulties. It provides another ring coupling configuration where two adjacent rings can share one switch. This typology is an ideal solution for applications that have inherent cabling difficulties.
How to Determine the Redundant Path
For Turbo Ring v2, the master is determined by two methods, one is a system MAC address election, the smallest MAC address will play the Master role; the other is user manual configuration to enable Master role on the switch. The redundant path is determined by “Ring Port 2”, which means the port set on “Ring Port 2” will become the blocking port.

Ring Coupling for a “Turbo Ring V2” Ring

Moxa’s Managed Switch Next Generation OS (v3.x) User Manual

106

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. The Coupling Port (Backup) on Switch A is used for the backup path, and connects directly to an extra network port on Switch C. The Coupling Port (Primary) on Switch B monitors the status of the main path, and connects directly to an extra network port on Switch D. With ring coupling has been established, Switch A can activate the backup path as soon as it detects a problem with the main path.
ATTENTION
Ring Coupling needs to be enabled on one coupling primary switch and one coupling backup switch as the Ring Coupler. The Coupler must designate different ports as the two Turbo Ring ports and the coupling port.
NOTE
You do not need to use the same switch for both Ring Coupling and Ring Master.
