Configuring one-to-one VLAN mapping

Configure one-to-one VLAN mapping on the customer-side ports of wiring-closet switches (see Figure 63) to isolate traffic of the same service type from different homes.

Before you configure one-to-one VLAN mapping, create the original VLAN and the translated VLAN.

To configure one-to-one VLAN mapping:

Step	Command	Remarks
1. Enter system view.	system-view	N/A
2. Enter Layer 2 Ethernet interface view or Layer 2 aggregate interface view.	Enter Layer 2 Ethernet interface view:interface interface-type interface-number Enter Layer 2 aggregate interface view:interface bridge-aggregation interface-number	N/A
3. Set the link type of the port.	Set the port link type to trunk:port link-type trunk Set the port link type to hybrid:port link-type hybrid	By default, the link type of a port is access.
4. Assign the port to the original VLANs and the translated VLANs.	For the trunk port:port trunk permit vlan vlan-id-list For the hybrid port:port hybrid vlan vlan-id-list tagged	N/A
