Lantech Layer3 Lite Platform (for OS3/OS4) is a scalable & advanced operating system built with modularity, resiliency, and serviceability at its foundation. Based on the VLAN routing standard, Lantech Layer3 Lite Platform comes with a Web UI interface and a command-line interface (CLI) like that of Lantech’s previous platform. The self-healing design of Lantech Layer3 Lite Platform makes zero-impact operations a reality.

Focused on the requirements of the data center, Lantech OS3/OS4 Layer3 Lite Platform provides a robust and comprehensive features that fulfill the switching and storage networking needs of present communication networks. Lantech OS3/OS4 Layer3 Lite Platform offers reliability, innovation, and operational consistency. Lantech OS3/OS4 Layer3 Lite Platform is based on our OS3/OS4 platform and adds major features of OS Layer 3, it runs on the Lantech OS3/OS4-supported hardware-based network switches, which include Lantech L6000 and L5000 Series Switches.

  • Command authorization
    Leverages RADIUS to link a custom list of CLI commands to an individual network administrator’s login; an audit trail log activity
  • Secure Web GUI
    Provides a secure, easy-to-use graphical interface for configuring the module via HTTPS
  • Dual flash images
    Provides independent primary and secondary operating system files for backup while upgrading
  • Multiple configuration files
    Stores easily to the flash image
  • Complete session logging
    Provides detailed information for problem identification and resolution
  • SNMPv1, v2c, and v3
    Facilitate centralized discovery, monitoring, and secure management of networking devices
    Uses standard SNMP to monitor essential network functions; supports events, alarm, history, and statistics group plus a private alarm extension group
  • Inter-VLAN Routing
    Route traffic between different VLAN by implementing a switch with routing function in the network.
  • Router-on-a-stick
    A type of routing configuration in which a single physical interface set as VLAN trunk port manages traffic between multiple VLANs from edge site.
  • VRRP
    Provides automatic assignment of available VLAN gateways to participating hosts and increases the availability and reliability of VLAN routing paths via automatic default gateway selections on different VLAN groups.
