VLAN mapping configuration examples

One-to-one and many-to-one VLAN mapping configuration
example
Network requirements
As shown in
•
Each household subscribes to PC, VoD, and VoIP services, and obtains the IP address through
DHCP.
•
On the home gateways, VLANs 1, 2, and 3 are assigned to PC, VoD, and VoIP traffic,
respectively.
To isolate traffic of the same service type from different households, configure one-to-one VLAN
mapping on the wiring-closet switches. This feature assigns one VLAN to each type of traffic from
each household.
To save VLAN resources, configure many-to-one VLAN mapping on the campus switch (Switch C).
This feature transmits the same type of traffic from different households in one VLAN. Use VLANs
501, 502, and 503 for PC, VoD, and VoIP traffic, respectively.
