VLAN mapping configuration examples
One-to-one and many-to-one VLAN mapping configuration
example
Network requirements
As shown in Figure 64, assign one VLAN for each type of traffic from each user on the wiring-closet
switches.
To prevent the maximum number of VLANs from being exceeded on Switch D, perform many-to-one
VLAN mapping on Switch C to transmit the same type of traffic from different users in one VLAN: use
VLAN 501 for PC traffic, VLAN 502 for VoD traffic, and VLAN 503 for VoIP traffic.
Because Switch C retains customer VLAN information, each type of traffic is still segregated by user, even
though it appears to be transmitted in one VLAN.
