UMN:CLI User ManualV5812G302.1 System FeaturesThis section introduces the main features of the V5812G GPON OLT system whichprovides Layer 3 switching, Ethernet switching and GPON functionalities.Virtual Local Area Network (VLAN)Virtual local area network (VLAN) is made by dividing one network into several logicalnetworks. Packets cannot be transmitted between different VLANs. Therefore it canprevent needless packets accumulating and strengthen security. The V5812G recognizes802.1Q tagged frame and supports maximum 4096 VLANs. Port-based, protocol-based,MAC-based, and subnet-based VLANs are supported in the V5812G.Quality of Service (QoS)For the V5812G, QoS-based forwarding sorts traffic into a number of classes and marksthe packets accordingly. Thus, different quality of service is provided to each class, whichthe packets belong to. The rich QoS capabilities enable network managers to protectmission-critical applications and support differentiated level of bandwidth for managingtraffic congestion. The V5812G support ingress and egress (shaping) rate limiting, anddifferent scheduling type such as Strict Priority (SP), Weighted Round Robin (WRR) andDeficit Round Robin (DRR).IP MulticastBecause broadcasting in a LAN is restricted if possible, multicasting could be usedinstead of broadcasting by forwarding multicast packets only to the member hosts whojoined multicast group. The V5812G provides IGMPv2, IGMP snooping and PIM-SM forhost membership management and multicast routing.SNMPSimple Network Management Protocol (SNMP) is to manage network elements usingTCP/IP protocol. The V5812G supports SNMPv1, 2, 3 and Remote Monitoring (RMON).Network operator can use MIB also to monitor and manage the V5812G.IP RoutingThe V5812G is Layer 3 switch, which has routing table and IP address as router.Therefore, it supports static routing, RIPv1/v2, OSPFv2 and BGPv4 for unicast routing.Dynamic Host Configuration Protocol (DHCP)The V5812G supports Dynamic Host Configuration Protocol (DHCP) server thatautomatically assigns IP address to clients accessed to network. That means it has IPaddress pool, and operator can effectively utilize limited IP source by leasing temporaryIP address. In Layer 3 network, DHCP request packet can be sent to DHCP server viaDHCP relay and option 82 function.
