◄ Industrial L2 / L3 Rackmount / Rail Ethernet Switch NMS, which integrates comprehensive network auto discovery, group IP address change and firmware monitoring features for auto topology discovery, device upgrade. | Comprehensive Redundant Solutions - Multiple Super Ring (MSRtm) The JetNet 4508i supports new generation ring technology - MSRTM (Multiple Super Ring), which includes various new technologies for different network redundancy applications and structures. It allows aggregating up to 4 Fast Ethernet Rings. With the MSRTM technology, a node can be configured to multiple...

Seamless Ring Port RestorationTM Seamless restoration is a new Korenix patented loss. With zero second restoration time, this mechanism technology which can restore a failed ring without eliminates any unstable status and guarantees the causing any loop problem, topology change and packet applications running non-stop. Rapid Dual Homing (RDHTM) Technology Rapid Dual Homing is also an important feature of secondary and standbys based on their link speed. The Korenix new generation Ring technology. It supports ring uplink with the highest speed is more likely to be active coupling with other...

Industrial L2 / L3 Rackmount / Rail Ethernet Switch TrunkRing is a new feature in MSR which merges the two technologies of RSR and link aggregation. It takes advantages of aggregation to enhance the link redundancy, while increasing the link speed. The ring will open only if all the aggregated links are Rackmount PoE Plus Switch Asymmetric TrunkRing broken. Link aggregation can be achieved by either static trunk or LACP. Not all the link sections in a TrunkRing need to be the same. Ring links can be either symmetric or asymmetric. Some are a single Industrial PoE Plus Switch Industrial...

| Link Aggregation Control Protocol Link Aggregation Control Protocol allows users grouping multiple Ethernet ports in parallel to increase the link bandwidth. The aggregated ports can be viewed as one physical port, so that the bandwidth is higher than just one single Ethernet port. The member ports of the same trunk group can balance the loading and backup with each other. The LACP feature is usually used when higher bandwidth is needed for the backbone network. This is a cost-effective way for transferring much more data. If the trunk port is also assigned as a ring port, it will become...

◄ Industrial L2 / L3 Rackmount / Rail Ethernet Switch Auto Topology Discovery & Efficient Management through LLDP | and Korenix NMS JetNet 4508i supports topology discovery or LLDP (IEEE 802.1AB Link Layer Discovery Protocol) function that can help users to discover multi-vendor's network devices on the same segment by an NMS system, which support LLDP function. With LLDP function, NMS can easily maintain the topology map, display port ID, port description, system description, VLAN ID, etc.. Once a link failure happens, the topology changed events are updated to the NMS to help users...
