What is Best-effort-priority and Best-effort-weight?

Hi Karfax,
You can refer to https://support.huawei.com/enterprise/en/network-management-control-analysis/imaster-nce-fabricinsight-pid-250872300/multimedia

I hope it helps!

Hello, friend!

DBA: 

The OLT uses DBA to dynamically adjust the upstream bandwidth allocated to different ONUs to address the burst traffic on the ONUs, meeting the ONU upstream bandwidth requirements and improving the utilization of the PON upstream bandwidth.

type4:

Indicates a DBA profile of the maximum bandwidth type. This type of bandwidth is the maximum bandwidth that can be used by an ONU to meet the ONU bandwidth requirement to the greatest extent. It is used for services such as Internet access service.

priority:

Indicates the priority of the best effort bandwidth allocation.

Numeral type. Range: 0-7. 0 indicates the lowest priority.

NOTE:

For boards that do not support priority configuration, the control board directly delivers priorities 0-7.

For boards whose highest priority is 3, if the configured value is greater than 3, the control board converts the value to 3 for delivery.

For boards whose highest priority is 7, the control board directly delivers priorities 0-7.

weight:

Indicates the weight of the best effort bandwidth allocation. This parameter can be configured only for DBA profiles in type 4 or non-NAB type 5. For other profiles.

Numeral type. Range: 1-10000.

In summary:

1. Type 4 is a type of ONU upstream bandwidth allocated by the OLT. Type 4 affects the ONU upstream bandwidth. 2. Priority 3 is greater than 0, and 0 is the minimum priority. Weight. 1000 is greater than 1.

Thanks!
