Figure 51 One-to-one VLAN mapping implementation
One-to-two VLAN mapping
Implement one-to-two VLAN mapping through the following configurations, as shown in Figure 52 :
• Apply an uplink policy to the incoming traffic on the customer-side port to tag the incoming packets
from a certain CVLAN with an outer SVLAN tag.
• Configure the customer-side port as a hybrid port, and assign the port to SVLANs as an untagged
member. When the port forwards the packets from these SVLANs, it removes their SVLAN tag.
Figure 52 One-to-two VLAN mapping
Two-to-two VLAN mapping
Implement two-to-two VLAN mapping through the following configurations, as shown in Figure 53 . For
uplink traffic from the SP 1 network, apply an uplink policy to the customer-side port of the SP 2 network
to replace the SVLAN with a new SVLAN. The process is the same for uplink traffic from the SP 2 network.
