Complete Layer 2 management switch with optional software package of IEC 62443, L3 Lite, L3, NAT and IEC 61375-2-5 ETBN



Lantech OS3/OS4 switch is powerful with complete Layer 2 management features and optional upgradable for future expansion, such as Layer 3 Lite, Layer 3, IEC61375-2-5 (ETBN), R-NAT, hardware NAT, PTP, etc.

DDoS security to protect switch and server; Optional IEC 62443 compliance with free one year service
Lantech OS3/4 platform is designed with high standard of cybersecurity to prevent the threats from network attack such as DDoS attacks and 802.1X security authentication. The optional cybersecurity IEC 62443 features include DHCP snooping, prevention of DDoS attack, Dynamic ARP Inspection, IPSource Guard, Port Security, Vulnerability checking, Encrypted file, Public keys, Strength password, Account management, Penetration and Stress test, and many more with up to 90 security measures.

MAC-based port authentication is an alternative approach to 802.1x for authenticating hosts connected to a port. By authenticating based on the host’s source MAC address, the host is not required to run a user for the 802.1x protocol. The RADIUS server that performs the authentication will inform the switch if this MAC can be registered in the MAC address table of switch.

Optional IEEE 1588 PTP V2 and 802.1AS for precise time protocol (OS4 only)
The Precision Time Protocol (PTP) is a protocol used to synchronize clocks throughout a network. The PTP V2 and gPTP supports transparent clock and two step processing that improves network time accuracy and precision.

DHCP option 82 & Port based, Mac based DHCP, Option 7/66, DHCP Snooping, IPv6 DHCP basic server
DHCP server can assign dedicated IP address by MAC or by port (Port based for single switch), it also can assign IP address by port for multiple switches with single DHCP option82 server. DHCP Snooping is supported. DHCP option66 server can offer IP address of TFTP server to DHCP client for VOIP application while DHCP option7 can offer IP address of logging server. Basic Ipv6 DHCP service can be supported.

User friendly GUI, Auto topology drawing
The user-friendly UI, innovative auto topology drawing and topology demo makes OS3/OS4 Ethernet switches much easier to get hands-on. The complete CLI enables professional engineer to configure setting by command line.

Enhanced G.8032 ring, 8 MSTI MSTP; MRP ring
Lantech OS3/OS4 Ethernet switches features enhanced G.8032 ring which can be self-healed in less than 20ms for single ring topology protection covering multicast packets. It also supports various ring topologies that covers enhanced ring and basic ring by easy setup than others. It supports MSTP that allows RSTP over VLAN for redundant links with 8 MSTI. MRP (Media Redundancy Protocol) can be supported for industrial automation networks.

Enhanced Storm control
Storm control prevents traffic on a LAN from being disrupted by a broadcast, multicast, or unicast storm on one of the physical interfaces and the detection is more precise and reaction is more efficient.

Protocol based VLAN; Subnet based VLAN; QinQ, QoS and GVRP
It supports the QinQ, QoS and GVRP for large VLAN segmentation. The protocol-based VLAN processes traffic based on protocol. It filters IP traffic from nearby end-stations using a particular protocol such as IP, IPX, ARP or other Ethernet-types in a Hex value. Subnet based VLANs group traffics into logical VLANs based on the source IP address and IP subnet. The above features can help to build VLAN in the network mixed with managed and un-managed switch as to define packets to which VLAN group based on protocol or subnet.

IGMPv3, GMRP, router port, MLD Snooping, static multicast forwarding and multicast Ring protection
The unique multicast protection under enhanced G.8032 ring can offer immediate self-recovery instead of waiting for IGMP table timeout. It also supports IGMPv3, GMRP, router port, MLD snooping and static multicast forwarding binding by ports for video surveillance application.

Support NTP, SNTP server with built-in RTC clock source (RTC is subject to model variant)
The support of NTP/SNTP is able to synchronize system clock in Internet. Lantech OS3/OS4 switch supports NTP server & server/client mode. The switch also built-in a real-time clock (RTC) for measurement the passage of time with a NTP server. (RTC is subject to model variant)

Enhanced environmental monitoring for switch inside information
The enhanced environmental monitoring can detect switch overall temperature, total power load, actual input voltage and current. It can send the SNMP traps alert when abnormal. (Subject to model variant)

Optional Layer3 Lite / Layer3 to be upgradable
Lantech OS3/OS4 platform is optional upgradable to L3 Lite or L3 for future expansion. The optional L3L/L3 supports enhanced routing functionality, including RIP v1/v2, OSPF, DVMRP, PIM, Static NAT, PAT, Port forwarding, etc. It provides better network performance for large scale applications. (NAT is only available on OS4-L3 platform)

Optional TTDP and R-NAT protocol for train application (EN50155 models)
Lantech OS3/OS4 platform complies with IEC 61375-3-4 (ECN) standard. The support of Ethernet Consist Network allows interconnection between end devices located in single consist of train and interoperability with IEC61375-2-5 (ETBN). The optional TTDP (Train Topology Discovery Protocol) can assign IP and Gateway IP automatically when train network topology is changed due to the adjustment of train cars. Exclusive DHCP and VLAN over TTDP can help bind device with certain IP assignment and segment VLAN in ECN network. The optional R-NAT (Railway-Network Address Translation) is under TTDP that simplifies the management of network address translation between ETB and ECN. (R-NAT is only available on OS4-L3 platform)
