H3C S6850 Series

To isolate traffic of the same service type from different households, configure one-to-one VLAN
mappings 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 mappings 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.
