How to Configure MDUs Subtended to an Huawei OLT?

Configuring MDUs Subtended to an OLT

MDUs are subtended to an Huawei OLT through the P2P board, thereby saving upstream optical fibers and simplifying the network and service configuration.

Service Requirements

• MDU_1 and MDU_2 are connected to an OLT through GE subtending, implementing the Internet access service.
• The Internet access service is provided in the PPPoE dialing mode.

Procedure

• Configure the your MA5600T or MA5603T or MA5608T.
1. Configure the port role.
   Configure the port role of the P2P board as a subtending port. The port roles of the P2P board are user port and subtending port. By default, the port role is user port.

   huawei(config)#interface eth 0/2
   huawei(config-if-eth-0/2)#network-role cascade
   huawei(config-if-eth-0/2)#quit

2. Create a VLAN and add an upstream port to the VLAN.
   Create smart SVLAN 100. The upstream port is port 0/9/0.

   huawei(config)#vlan 100 smart
   huawei(config)#port vlan 100 0/9 0

3. Configure a service port.
   Add the service port to the SVLAN by using default traffic profile 6. The CVLAN ID is 200, the same as the upstream VLAN ID of the MDU. MDU_1 and MDU_2 are connected to ports 0/2/0 and 0/2/1 of the OLT respectively.

   huawei(config)#service-port vlan 100 eth 0/2/0 multi-service user-vlan 200
    rx-cttr 6 tx-cttr 6
   huawei(config)#service-port vlan 100 eth 0/2/1 multi-service user-vlan 200
    rx-cttr 6 tx-cttr 6

4. Save the data.

   huawei(config)#save

Configure the MDUs.

The configurations of MDU_1 and MDU_2 are the same. The configuration of MDU_1 is used as an example.

1. Create a VLAN and add an upstream port to the VLAN.
   Create smart SVLAN 200. The upstream port is port 0/0/1.

Result

On the PC, the Internet access service is provided in the PPPoE dialing mode.
