If Is It Possible to Config the LAN Port of Huawei ONT to Trunk

Hi friend.

Between ONT and OLT, you can create multiple service ports to allow different VLAN passes.

Between ONT and AR router, you can set VLAN translation for the eth port (each ONT port support max translate 8 VLANs).

Below configuration example for your reference:

ont-lineprofile gpon profile-id 20 profile-name trucktest

  tcont 1 dba-profile-id 10

  gem add 1 eth tcont 1

  gem add 2 eth tcont 1

  gem mapping 1 0 vlan 3093

  gem mapping 2 0 vlan 3081

  commit

  quit

ont-srvprofile gpon profile-id 20 profile-nametrucktest

  ont-port pots adaptive 32 eth adaptive 8catv adaptive 8

  port vlan eth 1 translation 3081 user-vlan3081

  port vlan eth 1 translation 3093 user-vlan3093

  commit

interface gpon 0/x

ont  add 0 20 sn-auth 4857511111111111 omciont-lineprofile-id 20 ont-srvprofile-id 20

quit

service-port vlan 3089 gpon 0/2/0 ont 20 gemport 1multi-service  user-vlan  3089 tag-transform  translate

service-port vlan 3081 gpon 0/2/0 ont 20 gemport 2ulti-service  user-vlan  3081 tag-transform  translate

Thanks.

Hi Friend,

More one possibility:

Set report mapping to ONT ETH port, ETH port transparent all the VLANs, in the service port using other-all to identity all the VLANs and using default tag transform add the outer VLAN tag.

the following post has a scenario similar to the one you are trying to configure::

https://forum.huawei.com/enterprise/en/qinq-olt-ma5800-x2/thread/750901-100181

Eth 1 transparent = 

Configures the VLAN configuration type to transparent. In this mode, the packet is not processed. That is, the VLAN tag is not switched.

When the user-side packet carries a VLAN tag and the VLAN translation is performed on the OLT, use this parameter.
