Maximum 12+2G Rings Aggregation Capability Korenix JetNet 5828G supports MultiRing which allows aggregating multiple Rapid Super Rings. With the MultiRing technology all the Fast Ethernet and Gigabit Ethernet ports can be part of the ring ports. Besides, up to 12 100M Rings can be formed and 2 Gigabit Rings can be aggregated to single access switch. Moreover, after the rings are formed, the device can work as a layer 2 switch and allow all rings to communicate within the same VLAN. The JetNet 5828G can also work in a layer 3 mode, where it acts as the default gateway of the lower IP subnets and VLANs groups of each rings. These IP subnets and VLAN groups can inter-route within the single JetNet 5828G. With the layer 3 protocol supported, the technicians can easily plan the IP network infrastructure for the field stations, security filtering and wire-speed routing. Copper 100M Ring JetNet 4510 Giga Ring Copper or Fiber JetNet 5010G Giga Ring Up to 12 x 100M Rings + 2 Gigabit Rings Different VLAN/IP subnets Inter Routing Routing Protocol Routing is the process of moving packets through an internetwork, such as the Internet. To Route traffic, a router or layer 3 switch needs to know the destination IP address, sources IP it can learn from, the possible routes, finding the best route, maintaining and verifying routing information. If the next hop address is known or assigned by IT manager or service provider, the static route can direct the correct routing request to the connected interface. If not, the dynamic routing protocol is needed. The dynamic routing protocol includes unicast routing and multicast routing protocols. The unicast routing protocol includes hop based or distance vector based. RIP is the typical hop based, the less hops path is always the best route. OSPF is the typical distance vector base, the lowest cost is the best route path. To route multicast services, like the movie, video, industrial automation streams. The multicast routing and related protocols are needed. The DVMRP, PIM-DM, PIM-SM are supported by JetNet 5828G series.

Industrial L2 / L3 Rackmount / Rail Ethernet Switch Advanced Security by Layer 3 Access Control List After layer 3 interfaces are established, the IP interface or IP subnet can communicate as soon as the IP routing is enabled. To restrict the traffic routing and enhance the security protection, the Access Control List (ACL) makes it easy to limit certain devices communicating with the other addressed devices and by the specific protocol. Example rules include (1) administrator to multiple stations, (2) stations to stations and (3)stations to public servers…etc. The ACLs provide “Permit” and “Deny” rules for any or the specific host. The IP address, MAC address and port ID are the destinations allowed to be applied the rules. The protocol ID, QoS tag, TCP flag… are the operations which users prefer to control. Incoming Packet Processes with ACL ACL Table ACE 1 ACE 2 ….… ……. ……. Permit Deny The IP access rules can be applied through different subnets. Outgoing Packet The JetNet 5828G is equipped with one layer 2+ switch fabric which provides flexible ACLs for the specified subjects and operations within the same LAN. Industrial Intelligent NMS Rackmount PoE Plus Switch Industrial PoE Plus Switch Industrial 12-24V PoE Switch Industrial PoE Switch Rackmount L3/L2 Switch Gigabit Managed Switch Link Layer Discovery Protocol The Link Layer Discover Protocol (LLDP) was formally ratified as IEEE 802.1AB-2005. LLDP is the Layer 2 protocol that allows the network device/station to advertise connectivity & management information, the identity & major capabilities. It receives and establishes network management information on the local same network. In industrial environments, most vendors provide their own discovering protocols, window utility or other tools to manage their switches. The LLDP protocol fixes the interoperability among them. With LLDP supported, users can easily browse the network devices and establish the network management information schema for the stations. Supporting SNMP, LLDP and JetView protocol, the JetNet 5828G series can be easily discovered, port and ring status can be displayed by JetView Pro, Korenix designed Network Management System or other NMS which support SNMP and LLDP. The software can help administrators efficiently and effectively manage the industrial network.
