Flow chart

Procedure

Step 1

Create SVLANs and add an upstream port to them.

The VLAN type is Smart and the VLAN IDs are 100, 200, 400 and 500, VLAN 100 is for HSI

service; VLAN 200 is for VoIP service; VLAN 400 is for Wi-Fi service and VLAN 500 is for

the U2560 management channel. The VLAN for the Internet access service is a stacking VLAN.

Add the upstream port 0/19/0 to the VLAN.

huawei(config)#

vlan 100,200,400,500 smart

huawei(config)#

vlan attrib 100 stacking

huawei(config)#

port vlan 100,200,400,500 0/19 0

Step 2

Enables ARP proxy.

For different users of the same SVLAN, because the service ports of the smart VLAN are isolated

from each other, the voice media streams cannot interchange normally. Therefore, the ARP

proxy function of the OLT needs to be enabled.

Step 3

Configure GPON ONT profiles.

GPON ONT profiles include the DBA profile, line profile, service profile, and alarm profile.

DBA profile: A DBA profile describes the GPON traffic parameters. A T-CONT is bound

to a DBA profile for dynamic bandwidth allocation, improving the upstream bandwidth usage

rate.

Line profile: A line profile describes the binding between the T-CONT and the DBA profile,

the QoS mode of the traffic stream, and the mapping between the GEM port and the ONT-

side service.

Service profile: A service profile provides the service configuration channel for the ONT

that is managed through OMCI.

Alarm profile: An alarm profile contains a series of alarm thresholds to measure and monitor

the performance of activated ONT lines. When a statistical value reaches the threshold, the

host is notified and an alarm is reported to the log host and the NMS.

Configure a DBA profile.

Run the

display dba-profile

command to query the existing DBA profiles in the system.

If the existing DBA profiles in the system do not meet the requirement, run the

dba-profile

add

command to create a DBA profile.

HSI service: Set the DBA profile ID to 10, type to type4, and maximum bandwidth to

100 Mbit/s.

VoIP service: Set the DBA profile ID to 20, type to Type3, assured bandwidth to 15

Mbit/s, and maximum bandwidth to 30 Mbit/s.

Wi-Fi service: Set the DBA profile ID to 30, type to type4, and maximum bandwidth

to 200 Mbit/s.

U2560 management channel: Set the DBA profile ID to 40, type to Type2, assured

bandwidth to 15 Mbit/s.

huawei(config)#

dba-profile add profile-id 30 type4 max 204800

huawei(config)#

dba-profile add profile-id 40 type2 assure 30720

Configure an ONT line profile.

Create GPON ONT line profile 10.

HSI service: Bind the T-CONT which ID is 1 to DBA profile 10.

VoIP service: Bind the T-CONT which ID is 2 to DBA profile 20.

Wi-Fi service: Bind the T-CONT which ID is 3 to DBA profile 30.

U2560 management channel: Bind the T-CONT which ID is 4 to DBA profile 40.

Add GEM ports which are used to carry service streams of the ETH type and bind the GEM

ports to T-CONTs. Set the QoS mode to priority-queue (default).

HSI service: Add a GEM port which ID is 1 and bind the GEM port to T-CONT 1.

VoIP service: Add a GEM port which ID is 2 and bind the GEM port to T-CONT 2.

Wi-Fi service: Add a GEM port which ID is 3 and bind the GEM port to T-CONT 3.

U2560 management channel: Add a GEM port which ID is 4 and bind the GEM port

to T-CONT 4.

NOTE

To change the QoS mode, run the

qos-mode

command to configure the QoS mode to gem-car or flow-

car, and run the

gem add

command to configure the ID of the traffic profile bound to the GEM port.

When the QoS mode is PQ, the default queue priority is 0; when the QoS is flow-car, traffic profile 6

is bound to the port by default (no rate limitation); when the QoS mode is gem-car, traffic profile 6 is

bound to the port by default (no rate limitation).

gem add 2 eth tcont 2

huawei(config-gpon-lineprofile-10)#

gem add 3 eth tcont 3

huawei(config-gpon-lineprofile-10)#

gem add 4 eth tcont 4

Configure the mapping between the GEM port and the ONT-side service to the VLAN

mapping mode (default) and map the service port of CVLAN 20 to the GEM port.

HSI service: Map user-side VLAN 10 to GEM port 1.

VoIP service: Map user-side VLAN 20 to GEM port 2.

Wi-Fi service: Map user-side VLAN 40 to GEM port 3.

U2560 management channel: Map user-side VLAN 50 to GEM port 4.

huawei(config-gpon-lineprofile-10)#

gem mapping 3 3 vlan 40

huawei(config-gpon-lineprofile-10)#

gem mapping 4 4 vlan 50

After the configurations are complete, run the

commit

command to make the configured

parameters take effect.

huawei(config-gpon-lineprofile-10)#

commit

huawei(config-gpon-lineprofile-10)#

quit

Configure an ONT service profile.

The ID of the VLAN to which ETH port 1 belongs is 10.

The number of ports configured in the service profile must be the same as the actual number

of ONT ports. The flowing table lists the port capabilities ofHG8010/HG8240B/HG8245T/

HG8247T. The HG8247 is used as an example.

NOTE

The

port vlan

command is use for specifying a port VLAN and managing the attribute of the UNI port

on the ONT remotely. This command is applicable for only the L2 service (L2 Internet access service)

when the ONT functions as a bridge device. When the ONT functions as a gateway device, the

configuration of the port VLAN is implemented on the ONT Web page, NMS, or U2560 server.
