Configuring one-to-one VLAN mapping

Configure one-to-one VLAN mapping on the customer-side ports of wiring-closet switches (see Figure 79) 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

  • 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.

By default, no VLAN mapping is configured on an interface.
