6.4 How to Use VLAN Stacking on PON Ports
This tutorial introduces how to configure VLAN stacking for all VLANs and specified VLAN on PON ports.
6.4.1 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 forwards the tagged packets that are VLAN members on the UNI port to
the OLT. The OLT receives the single-tagged packets from multiple VLANs. The OLT will add an outer tag
(
2001 ) to the incoming packets and forward the double-tagged packets to the uplink.
The OLT will only process the outer VLAN ID ( 2001 ). All inner VLAN IDs will be transparent in the OLT
forwarding process.
