How about the capability of the ONT in supporting the VLAN access at L2?
1. 4K VLANs are supported on the OLT.
2. VLANs supported by the ONT at L2 are as follows: If the version of the ONT is V800R105C32B023/B036, only eight VLANs are supported on the ONT. The cause is that the PMC chip maintains a maximum of eight switch entries when the ONT is in the translation mode.
If the version of the ONT is V800R105C32B056, the ONT can work in the new transparent mode and the ONT supports up to 256 VLANs in this mode.
