| Gigabit Ethernet Redundant Ring and Ring Coupling Capability |
| Ethernet has become the default data communications medium for industrial automation applications. In fact, its not uncommon for the transfer of video, voice, and high-rate industrial application data to be integrated into one network. Moxas EDS-828/728 series Ethernet switches, which come equipped with a redundant Gigabit Ethernet protocol called Gigabit Turbo Ring, give system maintainers a convenient means of setting up a versatile yet stable Gigabit Ethernet network. |

| Port Trunking for Flexible Network Connections |
| IEEE 802.3ad (LACP, Link Aggregation Control Protocol) provides flexible network connections and a redundant path for critical devices. The EDS-828/728 Ethernet switches allow users to set up a wider communication path by aggregating up to four trunk groups in parallel. A maximum of eight ports can be assigned to one trunk group to optimize your network connection and redundant paths. When selected ports are grouped for trunking, LACP will exchange information to determine whether or not the ports selected in a group can be trunked together. |

| |
| IEEE 802.1X Enhances User Authentication |
| The EDS-828/728 series Ethernet switches support IEEE 802.1X (Port-based Network Access Control) to enhance user authentication. When IEEE 802.1X is activated, only authorized users can access the port. Authentication is done using the local user database or an external RADIUS server. |
|
| |
| HTTPS and SSH Enhance Network Security |
| In order to protect data from being intercepted, the EDS-828/728 Ethernet switches support the HTTPS and SSH protocols for transferring data over the Internet in an encrypted form. If you are changing the configuration of an Ethernet switch online, please make sure that it is done over HTTPS and SSH so that the data remains secure. |
|
| IGMP Snooping and GMRP for Filtering Multicast Traffic |
The EDS-828/728 Ethernet switches support IEEE 802.1D-1998 GMRP (GARP Multicast Registration Protocol) and IGMP snooping to provide the ability to prune multicast traffic so that the traffic only travels to those end destinations that require this kind of traffic. As a result, the amount of traffic on the Ethernet LAN is reduced.

| VLAN Eases Network Planning |
VLANs can be used to overcome restrictions imposed by the physical network connections. In one respect, devices connected to different physical networks can be allowed to communicate easily by assigning them to the same VLAN. In addition, devices assigned to different VLANs will not be able to communicate with each other, providing extra security and protection from unwanted invasion or traffic. The EDS-828/728 Ethernet switches support 802.1Q VLAN and GVRP protocol, which can exchange the same interoperable parameters to keep consistent VLAN settings over the entire network.
|
|
| QoS Increases Determism |
| Quality of Service (QoS) provides a traffic prioritization capability to ensure that important data is delivered consistently and predictably. The EDS-828/728 series Ethernet switches 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 QoS capability of the EDS-828/728 Ethernet switches improve your industrial networks performance, and increase determinism for mission-critical applications. |
|
| RMON for Efficient Network Monitoring and Proactive Capability |
| RMON (Remote Network Monitoring) is an IETF (Internet Engineering Task Force) standard monitoring specification that allows various network agents and console systems to exchange network monitoring data. RMON provides you with comprehensive network fault diagnosis, planning, and performance-tuning information, and helps you manage your network in a more proactive manner. If configured correctly, RMON probes deliver information before problems occur, allowing you to take action before the problems affect users. |
|
| Bandwidth Management Prevents Unpredictable Network Status |
| The EDS-828/728 series Ethernet switches not only prevent broadcast storms, but can also configure the rate limiting of unicast/multicast/broadcast packets, and in this way gives administrators full control of limited bandwidth to prevent unpredictable faults. |
|
| Port Mirroring for Online Monitoring |
| In some cases, a network is so large that it is difficult to achieve the expected communications level. Industrial communications applications use more of a command-response style than the file-transfer style used in office network environments. This means that when first setting up an industrial Ethernet network, control engineers may need to use a second port to monitor the actual activity between their devices and computer host. The EDS-828/728 series mirroring port function helps ensure that the system behaves as expected. |
|
| Automatic Warning by Event |
Warning by e-mail or SNMP Trap
The EDS-828/728 series Ethernet switches can send out a warning e-mail or SNMP trap when an exception is detected, providing system managers with real-time alarm messages.
Warning by Relay Output
The EDS-828/728 series Ethernet switches provide two relay outputs that can be set up to indicate events with different importance to notify or warn engineers in the field, so the engineer can use the appropriate emergency maintenance procedures to respond quickly to higher priority messages.
DI to Integrate Other Important Sensors
With two digital inputs, the EDS-828/728 series Ethernet switches can integrate sensors into its automatic alarm mechanism, sending warning messages to an IP network by e-mail notification. |

| Network Management with Moxa SNMP OPC Server Software |
| The Moxa SNMP OPC Server Pro software package can convert SNMP into OPC format. The vertical integration of SNMP management information into existing OPC-based SCADA-packages gives customers the ability to establish an Ethernet network management application that is integrated with existing visualization and control applications. |
