Figure 56 Application scenario of one-to-one VLAN mapping
To further sub-classify each type of traffic by customer, perform one-to-one VLAN mapping on the
wiring-closet switches, and assign a separate VLAN for each type of traffic from each customer.
Application scenario of one-to-two and two-to-two VLAN
mapping
Figure 57
