Figure 59 Many-to-one VLAN mapping implementation
One-to-two VLAN mapping
In Figure 60 , one-to-two VLAN mapping is implemented on the customer-side port to add the SVLAN tag
for the uplink traffic.
For the downlink traffic to be correctly sent to the customer network, make sure the SVLAN tag is removed
on the customer-side port before transmission. Use one of the following methods to remove the SVLAN
tag from the downlink traffic:
•
Configure the customer-side port as a hybrid port and assign the port to the SVLAN as an untagged
member.
• Configure the customer-side port as a trunk port and configure the SVLAN as the PVID.
Figure 60 One-to-two VLAN mapping implementation
Two-to-two VLAN mapping
In Figure 61 , two-to-two VLAN mapping is implemented on the customer-side port and replaces VLAN
tags as follows:
•
Replaces the CVLAN and the SVLAN with the CVLAN' and the SVLAN' for the uplink traffic.
• Replaces the SVLAN' and CVLAN' with the SVLAN and the CVLAN for the downlink traffic.
