VLAN Mapping Configuration Examples
One-to-One and Many-to-One VLAN Mapping Configuration Example
Network requirements
As shown in Figure 21-8 , 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.
