Figure 56 Tutorial: VLAN Stacking for All VLANs on PON Ports
1 Create the VLAN in the OLT and assign member ports.
2 Configure VLAN translation on a UNI port of the OLT.
6.5 How to Use VLAN Stacking on ONTs
This tutorial introduces how to configure VLAN stacking for all VLANs and specified VLAN on the ONTs
connected to the PON ports.
6.5.1 Apply VLAN Stacking to All VLANs
Scenario
PC2 transmits untagged VLAN traffic to Switch 1. Switch 1 adds the VLAN tag and forwards the tagged
packets to the ONT.
The ONT receives the single-tagged packets from multiple VLANs. The ONT verifies that the single-
tagged packets are the VLAN members on the UNI port. The ONT will add an outer tag (2001) to the
incoming packets and forward the double-tagged packets to the OLT.
The OLT will only process the outer VLAN ID (2001). All inner VLAN IDs will be transparent in the OLT
forwarding process.
