System Features
This section introduces the main features of the V8102 GPON OLT system which pro-
vides 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 logical
networks. Packets cannot be transmitted between different VLANs. Therefore it can pre-
vent needless packets accumulating and strengthen security. The V8102 recognizes
802.1Q tagged frame and supports maximum 4096 VLANs. Port-based, protocol-based,
MAC-based, and subnet-based VLANs are supported in the V8102.
Quality of Service (QoS)
For the V8102, QoS-based forwarding sorts traffic into a number of classes and marks
the packets accordingly. Thus, different quality of service is provided to each class, which
the packets belong to. The rich QoS capabilities enable network managers to protect mis-
sion-critical applications and support differentiated level of bandwidth for managing traffic
congestion. The V8102 support ingress and egress (shaping) rate limiting, and different
scheduling type such as Strict Priority (SP), Weighted Round Robin (WRR) and Deficit
Round Robin (DRR).
IP Multicast
Because broadcasting in a LAN is restricted if possible, multicasting could be used in-
stead of broadcasting by forwarding multicast packets only to the member hosts who
joined multicast group. The V8102 provides IGMPv2, IGMP snooping and PIM-SM for
host membership management and multicast routing.
SNMP
Simple Network Management Protocol (SNMP) is to manage network elements using
TCP/IP protocol. The V8102 supports SNMPv1, 2, 3 and Remote Monitoring (RMON).
Network operator can use MIB also to monitor and manage the V8102.
IP Routing
The V8102 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 V8102 supports Dynamic Host Configuration Protocol (DHCP) server that automati-
cally assigns IP address to clients accessed to network. That means it has IP address
pool, and operator can effectively utilize limited IP source by leasing temporary IP ad-
dress. In Layer 3 network, DHCP request packet can be sent to DHCP server via DHCP
relay and option 82 function.
