Figure 70 One-to-two VLAN mapping
Two-to-two VLAN mapping
Implement two-to-two VLAN mapping through the following configurations, as shown in Figure 71.
• For uplink traffic, apply an inbound policy on the customer-side port to replace the SVLAN with a
new SVLAN, and apply an outbound policy on the network-side port to replace the CVLAN with a
new CVLAN.
• For downlink traffic, apply an outbound policy on the customer-side port to replace the double tags
with the original VLAN tag pair.
