OLT and ONU ,QnQ config for IPoE

Dear , Your help will be highly appreciated to understand me the following command :

OLT:

MA5608T(config)# service-port vlan 100 gpon 0/0/15 ont 2 gemport 2 multi-service user-vlan  20 tag-transform translate-and-add inner-vlan 30 inbound traffic-table index 9  outbound traffic-table index 9.

// outer-vlan(S-vlan) = 100, ont id = 2, gemport 2 mapping to user-vlan 20, inner-vlan= 30.

ONU:

MA5612(config)#service-port vlan 20 eth 0/4/0 multi-service user-vlan untagged inbound
traffic-table index 6 outbound traffic-table index 6.

// s-vlan = 20, eth-port of>

BRAS(CX600-X8):

Hi h80023258, Id like to reply your question .

I draw a picture according to your discription, see as follows.

Hello kevin,

Do the following description help to justify your answer:

Translate-and-add: Indicates the translation of the VLAN 20 and the adding of a tag 30. The C-VLAN tag =20 is translated and an S-VLAN tag=30 is added. That is, the user packet carries two VLAN tags (S+C)=100+30:20(20 translated to 30) for upstream transmission. This mode is applicable to:

• Service streams whose S-VLAN is a stacking VLAN= 100, with a specified C-VLAN=20, VLAN=30. The C-VLAN ID ranges from 1 to 4095 or is 0 (priority-tagged).
• Service streams in the transparent-and-add mode and whose S-VLAN is a QinQ VLAN=100.

Inner vlan = 30: When the forward mode of the service VLAN at a service port is S+C, this parameter must be unique in the S-VLAN if the translate-and-add.

Thank you
