It delivers ITU G.8032 enhanced ring recovery less than 20ms for single ring, comprehensive QoS, VLAN, GVRP, advanced security SSH v2/SSL, INGRESS ACL L2/L3, IGMPv1/v2/v3/router port, DHCP server/relay, jumbo frame which are important features required in mid and large network. It also supports Cisco Discovery Protocol (CDP) and LLDP for Ciscoworks to detect the switch info and to be shown on L2 map topology.

PoE at/af up to 8 Ports with detection and scheduling
Lantech TPGR-3208T supports advanced PoE management including PoE detection and scheduling. PoE detection can detect if the connected PD hangs then restart the PD; PoE scheduling is to allow pre-set power feeding schedule upon routine time table. Each PoE ports can be Enabled/disabled, get the voltage, current, Watt, and temperature info displayed on WebUI, CLI, SNMP or OpenAPI*.

Support RTC (Real Time Clock) with longevity Golden Capacitor
Our switch supports RTC which is powered by a golden capacitor, ensuring accurate real-time event logs. Unlike traditional batteries, golden capacitors offer superior reliability, and longevity, without a need to change battery.

Reliable eMMC for better power efficiency and reliability
The T(P)GR-3208T utilizes eMMC for firmware storage. The eMMC with integrated controller that offloads and simplifies the task for the main processor. Its standard interface simplifies the design process while delivering improved power efficiency and enhanced reliability, thereby extending the storage’s lifespan. increasing the lifespan of the storage.

Miss-wiring avoidance, Node failure protection, Loop protection
The T(P)GR-3208T also embedded several features for stronger and reliable network protection in an easy and intuitive way. When the pre-set ring configuration failed or looped by miss-wiring, Lantech T(P)GR-3208T is able to alert with the LED indicator and disable ring automatically. Node failure protection ensures the switches in a ring to survive after power breakout is back. The status can be shown in NMS when each switch is back. This feature prevents the broken ring and keep ring alive without any re-configuration needed. Loop protection is also available to prevent the generation of broadcast storm when a dumb switch is inserted in a closed loop connection.

User-friendly GUI, Auto topology drawing, Enhanced Environmental Monitoring
The user-friendly UI, innovative auto topology drawing and topology demo makes T(P)GR-3208T much easier to get hands-on. The complete CLI enables professional engineer to configure setting by command line. It supports enhanced environmental monitoring for actual input voltage, current, ambient temperature and total power load.

mDNS (Multicast DNS) feature
mDNS (Multicast DNS) enables hosts in the LAN to discover and communicate with each other in compliance with the DNS protocol without a traditional DNS server.

Support Open API* for better switch performance
The switch supports Open API* that uses JSON format to access and use data for GET, PUT, POST and DELETE types to avoid traditional SNMP management occupying CPU utilization.

Certified cybersecurity development process with IEC 62443-4-1, and IEC 62443-4-2** compliance with physical tamper resistance and detection for integrity and authenticity of the boot process
Lantech OS2 platform is designed with a high standard of cybersecurity to prevent threats from network attacks. To ensure the safety and reliability of communication networks, Lantech software development is certified with IEC 62443-4-1 security process standards and the switch is also compliant to IEC 62443-4-2**. The switch uses roots of trust to verify the integrity and authenticity of the firmware, software, and configuration data needed for the switch’s boot process.

Enhanced G.8032 ring, 8 MSTI MSTP
Lantech T(P)GR-3208T 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 each spanning tree for each VLAN for redundant links with 8 MSTI.

DHCP option 82 & Port based, Mac based DHCP, Option66, DHCP Snooping
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.

WAN supported
Static IP address, PPPoE (V4&V6), DHCP client, NAT (V4) 3 routing functions Static route, dynamic route (RIP/OSPF) Firewall Port forwarding, DMZ, Filtering, Remote admin, DDoS protection

GVRP supported
It supports the GVRP for large VLAN segmentation.

IGMPv3, MLD snooping, query, GMRP, router port, 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 IGMP v3 with Query mode for multimedia, GMRP, router port, MLD snooping and static multicast forwarding binding by ports for video surveillance applications.

802.1X security by MAC address
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.

Editable configuration text file; Factory reset pin; CPU watchdog
The configuration file of Lantech T(P)GR-3208T can be exported in text file so that it can be edited and configured back to switch with ease for mass deployment. Factory reset pin can restore the setting back to factory default and built-in watchdog design can automatically reboot the switch when CPU is found dead.

USB port for backup, restore configuration and upgrade firmware
The built-in USB port can upload/download the firmware, export and import configuration.

MQTT – Publisher & Broker
MQTT is a publish-subscribe-based messaging protocol and works on top of the TCP/IP protocol. An MQTT system comprises one broker and several clients, where clients can either be publishers or subscribers. The publishers send data to the broker in the form of MQTT packets, which consist of a “topic” and “payload”, then the broker distributes the “payload” to the subscribers based on which “topics” they have subscribed.

Redundant dual power input design (24VI-24TVI model); inrush current prevention and polarity reverse protection
The Lantech T(P)GR-3208T is designed with dual power which can accept 9V~36VDC for bus with galvanic PoE isolation, 24TVI for train use which is 16.8-56VDC with galvanic PoE isolation. The redundant power input design prevents inrush current and safeguards against polarity reversal. The built-in PoE galvanic isolation up to 1.5KVDC can provide power input to PoE port insulation to prevent cable short, spike, and surge flooding through PoE cabling from damaging the POE port or connected device.

Optional bypass relay prevents from power loss
The optional bypass relay is set to bypass the switch to the next one when power is off in order to protect the network from crashing. Lantech bypass caters to remain in bypass mode until the switch is completely booting up when power is back to avoid another network lost. Smart bypass can be activated when switch encounters power failure. (-BT model)

E-marking certificate; ISO 16750-2 compliant
