VLAN mapping implementations

Figure 65 shows a simplified network that illustrates basic VLAN mapping terms.

Basic VLAN mapping terms include the following:

One-to-one VLAN mapping

As shown in Figure 66, one-to-one VLAN mapping is implemented on the customer-side port and replaces VLAN tags as follows:

Many-to-one VLAN mapping

As shown in Figure 67, many-to-one VLAN mapping is implemented on both the customer-side and network-side ports as follows:

One-to-two VLAN mapping

As shown in Figure 68, 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:

Two-to-two VLAN mapping

As shown in Figure 69, two-to-two VLAN mapping is implemented on the customer-side port and replaces VLAN tags as follows:
