OVERVIEW

Lantech Layer3 Lite / Layer3 software (for OS3/OS4 switches) are advanced routing protocols across VLAN, multicast functions to achieve safer security and better performance network. The VRRP can help to be fault-tolerant and improve the fault isolation on the network. DHCP L3 and L2 relay can send assigned IP addresses across VLAN for easy devices management. Comprehensive multicast routing features including PIM-SM/DM/SSM/BSR and DVMRP can correctly and efficiently establish and route the multicast packets with loop free path.


Lantech OS3/OS4 switches run with dual images firmware with Nand-flash protection mechanism to ensure the switch system’s reliability and robustness during the harsh applications.

FEATURES & BENEFITS - L3L

  • 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.
  • Static route (Up to 32)
    Set routing path manually, static routes are fixed and do not change if the network is changed or reconfigured.
  • Rescue mode
    Offers the ability to repair operating system if the booting image of the switch is damaged.
  • PIM-SM/DM/SSM
    Protocol-Independent Multicast (PIM) is a family of multicast routing protocols for Internet Protocol (IP) networks that provide one-to-many and many-to-many distribution of data over a LAN, WAN or Internet. PIM Sparse Mode (PIM-SM) explicitly builds unidirectional shared trees rooted at a rendezvous point (RP) per group, and optionally creates the shortest-path trees per source. PIM Allow RP (Rendezvous Points) enable the receiving device to use its own RP to create state and build shared trees when a PIM Join is processed and a different RP is identified. Lantech switches support static RP client and dynamic RP address (BSR). BSR (Bootstrap) can let Lantech switch find address of RP automatically. PIM Dense Mode (PIM-DM) uses dense multicast routing. It implicitly builds shortest-path trees by flooding multicast traffic domain wide, and then pruning back branches of the tree where no receivers are present. PIM Source-Specific Multicast (PIM-SSM) builds trees that are rooted in just one source, offering a more secure and scalable model for a limited number of applications (mostly broadcasting of content).
  • OSPF
    Open Shortest Path First (OSPF) protocol is an Interior Gateway Protocol used to distribute routing information within a single Autonomous System.
  • TTDP (IEC61375-2-5)**
    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.
  • 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
  • SNMP MIB – RMON
    Uses standard SNMP to monitor essential network functions; supports events, alarm, history, and statistics group plus a private alarm extension group
  • 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

FEATURES & BENEFITS - L3

L3 includes all L3L features mentioned above plus the following features:

  • DVMRP
    Distance Vector Multicast Routing Protocol (DVMRP) is a routing protocol used to share information between routers to facilitate the transportation of IP multicast packets among networks.
  • RIP v1/v2
    Routing Information Protocol (RIP) is a dynamic routing protocol which uses hop count as a routing metric to find the best path between the source and the destination network.
