Dear All, how are you?

Maybe some of you have asked if it?s possible to deploy VLAN Trunk in the Ethernet port of an ONT. In my experience I could do it using QinQ VLAN tag in the service profile of the HG8245 and works very fine, even more, I deploy one port of these ONTs with three VLANs and works ok.

The only recomendation for this deployment is not to pass more than 5 VLANs in the same ETH port of the ONT.

Below the script and E2E Diagram of the solution:

Script:

ont-srvprofile profile-name ONT_00CL2
  ont-port pots 2 eth 4
  port vlan eth 1 q-in-q 2501 user-vlan 1044 //Where 2501 is S-VLAN and 1044 is C-VLAN
  port vlan eth 1 q-in-q 2502 user-vlan 2044 //Where 2502 is S-VLAN and 2044 is C-VLAN
  port vlan eth 3 q-in-q 2500 user-vlan 46 //Where 2500 is S-VLAN and 46 is C-VLAN

  port vlan eth 4 q-in-q 2503 user-vlan 86 //Where 2503 is S-VLAN and 86 is C-VLAN

  port vlan eth 4 q-in-q 2504 user-vlan 246 //Where 2504 is S-VLAN and 246 is C-VLAN

  port vlan eth 4 q-in-q 2505 user-vlan 1004 //Where 2505 is S-VLAN and 1004 is C-VLAN

Observation: S-VLAN does not need to be created with QinQ attribute in the OLT, the QinQ vlan tag is added and stripped on the ONT side.

Hope this can be useful for someone!

good post, Thanks for sharing

Woooow awesomeee, I work for PAE outsoucing Huawei Mexico, our customer Iusacell has asked before about this soluction, is really clear your explanation, I will suggest customer this configuration to be test, thank a lot!!!

Good post, i think it is useful to others.

Thank you for sharing, waiting for more posts.

What a good post! thanks sevillaf, you can always give us surprise

Thanks for the so detailed example, it helps me a lot//

BTW, what you mentioned " The only recomendation for this deployment is not to pass more than 5 VLANs in the same ETH port of the ONT." , is it a internal limitation ? I mean , is it a hardware limitation ?

Hi sevillaf, I have two questions,

1. For what scenario should you deploy one port of these ONTs with three different user VLANs  ? 

2. The E2E Diagram  is easy to understand, is it a snap from the U2000 NMS ?

Thanks for the so detailed example, it helps me a lot//

Well, I dont think there is a such hardware limitation for each ONT port, is it means that  customers can usually enjoy no more than five kind of services , so more VLANs are unnecessary ?

Hi Kevin!

Below my answers:

1. It?s because in that port I need to deploy three services that need to be isolated. In other words each user vlan corresponds to one VPN service deployed in a router subif who strip the S-VLAN.

2. Yes my friend it?s a snapshot from U2000. It?s very illustrative this diagram and I use it a lot!

Best Regards!

Hi my friend! below my answers:

is it a internal limitation ? I mean , is it a hardware limitation ? I don?t think is a hardware limetation, I consider this a best practice only, with more than 5 VLANs in an eth port with a rate of 100Mbps, maybe your BW won?t satisfy the service requirements. Maybe more than 5 vlans is too much.

Hope this can answer your doubt.

Best Regards!
