Configuring One-to-One VLAN Mapping
Perform one-to-one VLAN mapping on wiring-closet switches (see Figure 21-1 ) to isolate traffic by
both user and traffic type.
Perform these tasks to configure one-to-one VLAN mapping:
Task Description
Configuring an uplink policy Creates CVLAN-to-SVLAN mappings (required).
Configuring a downlink policy Creates SVLAN-to-CVLAN mappings (required).
Configuring the customer-side port
Configures settings required for one-to-one VLAN mapping
(required).
Configuring the network-side port
Configures VLAN settings required for normal communication
(required).
Configuration prerequisites
Create CVLANs and SVLANs, and plan CVLAN-SVLAN mappings.
Configuring an uplink policy
Follow these steps to configure an uplink policy to map each CVLAN to a unique SVLAN:
