VLAN mapping configuration examples
One-to-one and many-to-one VLAN mapping configuration
example
Network requirements
As shown in Figure 70 :
• Each home is offered PC, VoD, and VoIP services, connects to a wiring-closet switch through the
home gateway, and obtains the IP address through DHCP.
• Assign VLAN 1 for PC traffic, VLAN 2 for VoD traffic, and VLAN 3 for VoIP service traffic on the
home gateways.
• To isolate traffic of the same service type from different homes, assign one VLAN for each type of
traffic from each user on the wiring-closet switches.
• To save the VLAN resources, perform many-to-one VLAN mapping on the campus switch (Switch C)
to transmit the same type of traffic from different homes in one VLAN: use VLAN 501 for PC traffic,
VLAN 502 for VoD traffic, and VLAN 503 for VoIP traffic.
