QinQ OLT MA5800-X2

Hello User. we are reviewing your question and we will answer you shortly. Thanks.

Hello, friend!

I understand that you want to add Q-in-Q VLAN 4000 to the downstream VLAN 1-4094 of the switch through the OLT, and then send the downstream VLAN to the ONT.

You can refer to the following configuration:

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.

HUAWEI(config)#vlan 100

HUAWEI(config)#port vlan  100 0/3 0

HUAWEI(config)#vlan attrib 100 q-in-q

HUAWEI(config)#ont-lineprofile gpon profile-id 10 profile-name QinQ100

HUAWEI(config-gpon-lineprofile-10)#tcont 1 dba-profile-id 10

HUAWEI(config-gpon-lineprofile-10)#mapping-mode port

HUAWEI(config-gpon-lineprofile-10)#gem  add 0 eth tcont 1

HUAWEI(config-gpon-lineprofile-10)#gem mapping  0 0 eth 1

HUAWEI(config-gpon-lineprofile-10)#commit

HUAWEI(config-gpon-lineprofile-10)#quit

HUAWEI(config)#ont-srvprofile gpon profile-id  10 profile-name QinQ100

HUAWEI(config-gpon-srvprofile-10)#ont-port eth 4 pots 2 catv 1

HUAWEI(config-gpon-srvprofile-10)#port vlan  eth 1 transparent

HUAWEI(config-gpon-srvprofile-10)#commit

HUAWEI(config-gpon-srvprofile-10)#quit

HUAWEI(config)#interface gpon 0/1

HUAWEI(config-if-gpon-0/1)#ont add 2 3 sn-auth 48575XXXXXXXXXXX omci ont-lineprofile-id 10 ont-srvprofile-id 10 desc QinQ100

HUAWEI(config-if-gpon-0/1)#quit

HUAWEI(config)#service-port vlan 100 gpon 0/1/2 ont 3 gemport 0 multi-service  user-vlan  other-all tag-transform default

Thanks!

My Friend, i tried it but don't successful. I cannot receive IP and on switch Core, when i use CDP i cannot see the switch

Follow my config:

vlan 4000 smart
vlan attrib 4000 q-in-q


ont-lineprofile gpon profile-id 2048 profile-name "Q-IN-Q_CEA_X_GAIA"
 mapping-mode port
 tcont 1 dba-profile-id 500
 gem add 0 eth tcont 1
 gem mapping 0 0 eth 1
 commit
 quit

ont-srvprofile gpon profile-id 2048 profile-name "Q-IN-Q_CEA_X_GAIA"
 ont-port eth 4
 port vlan eth 1 transparent
 commit

interface gpon 0/1

ont add 0 2 sn-auth "48575443B16Exxxx" omci ont-lineprofile-id 2048 ont-srvprofile-id 2048 desc "Q-IN-Q_CEA_X_GAIA"

service-port 5 vlan 4000 gpon 0/1/0 ont 2 gemport 0 multi-service user-vlan other-all tag-transform default

Hello, friend!

I checked your configuration information, and the configuration is valid. Can you tell me how you tested it? 

From the configuration layer, I cannot locate the cause of the problem. Therefore, I need to capture packets on the interface for analysis. 

Because that involves sensitive network and device information is recommended to contact Huawei technical support engineers for solutions.

Huawei Enterprise Network Technical Support Hotline: https://e.huawei.com/en/service-hotline-query

Good luck!

Hello, friend!

Do you mean the CDP protocol by CDP? I am mainly responsible for devices in the access domain of Huawei. After learning about this protocol, I confirm that this protocol is a proprietary device discovery protocol of other vendors and can only discover devices of this vendor.

You can use the LLDP protocol to check whether discovers the device.

As you do not provide the specific model of the device in the topology diagram, so I think all devices on your topology are Huawei devices by default.

Thanks!

Interesting. Thank you for sharing.

Hi friend, thanks for the support. I've already opened a call with tac, but they reported that OLT doesn't support QinQ configuration. My SR 5851647, could you help me to validate if this information is true?

Hello, friend!

I've read the details in the SR, but I'm wondering if the customer's requirements are the same as those described in the post. 

If the customer's requirements are the same as those described in the post, the configuration solution provided by me can meet the customer's requirements. 

If the customer's requirements are inconsistent with those described in the post, you need to contact the Mexico Technical Support Dept again, who will confirm with us.

Thanks!

Mexico Technical team told us that OLT cannot add the second tag (4000) to vlans 1 to 4094.

And that the command vlan attrib 100 q-in-q is just to inform you that the OLT already has a second VLAN tag
