How to support more than 256 VLANs on the UA5000 When the UA5000 uses the EP1A (EPON) board for interconnection with the MA5680T in the upstream direction?
1. The MA5680T allows up to 256 VLANs to pass each ONT. This is a feature for the MA5680T earlier than MA5680 V800R105C33B050
The UA5000 (Using the EP1A board for upstream transmission) functions as an ONT and is managed by the MA5680T.
2. Each common traffic stream uses one VLAN. That is, one ONT can be configured with up to 256 common traffic streams.
3. To support the forwarding of more than 256 CVLANs when the UA5000 uses the EP1A board for upstream transmission, you can enable the QinQ VLAN or VLAN stacking function on the OLT. For details about the configuration, see the related configuration manual.
