One-to-two VLAN mapping
Two-to-two VLAN mapping
Implement two-to-two VLAN mapping through the following configurations, as shown in
Figure 61
.
•
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.
Figure 61
Two-to-two VLAN mapping implementation
NOTE:
In two-to-two VLAN mapping implementations, you can configure VLAN mapping to replace only the
outer VLAN tags or inner VLAN tags as needed.
VLAN mapping configuration tasks
Use the VLAN mapping methods as appropriate to the roles of your switches in the network, as described
in this table:
Task
Switch role
Configuring one-to-one VLAN mapping
Wiring-closet switch
Configuring one-to-two VLAN mapping
Edge switch connecting users to SP networks
