Bandwith Control of HG8546M

Limit Rate of the Ethernet Port of an ONT

1. In the commercial release, GPON does not support the rate limitation function of an ONT.

2. EPON supports the rate limitation function of an ONT. 
In the case of the OLT in version R105C33B050, you can configure the rate limitation function by configuring the EPON ONT ports. 
In the EPON config mode, use policing <cir> <cbs> <ebs> in the ont port attribute <portid> <ontid> fe < ont-portid> command to set the upstream rate, and use ds-policing <cir> <pir> to set the downstream rate.

This is a carrier product, It is recommended that you contact the local tac for confirmation. You can find the HotLine Number and Support Mail of the TAC in the following website:

Hello,

As such, this cannot be done from the ONT, it must be done from the OLT with the following parameters:

Hello,

It seems the HG8546M does not support user-based bandwidth.  

If you restrict the bandwidth first, you can try to restrict the user access control protocol to restrict the bandwidth. For example, restrict a user to access only HTTP.  

For details, you can log in to the WebUI of HG8546M and choose Security > User Access Control Configuration.

Hello, friend!

The HG8546m you are using does not support broadband restrictions.

Perform rate limitation on the ONT, you need to perform the following operations on the OLT:

1. Run the dba-profile add command to add a DBA profile. The DBA profile is used to schedule the ONT upstream bandwidth properly, achieving the best bandwidth utilization.

A DBA profile supports five types (Type1 to Type5). Generally, services with higher priorities adopt Type1 or Type2 DBA profiles and services with lower priorities adopt Type3 or Type4 DBA profiles.

2. Run the ont-lineprofile gpon command to add a GPON ONT line profile, and then enter the GPON ONT line profile mode.

3. Run the tcont command to bind a T-CONT to the DBA profile.

It is recommended that one service type use one T-CONT and different T-CONTs be planned with different bandwidth assurance types.

4. Run the qos-mode command to configure a QoS model of the GPON ONT line profile to ensure that the QoS model is the same as that of the GEM port.

By default, the QoS model of the GPON ONT line profile (that is, the ONT scheduling mode) is a priority queue (PQ). The QoS model includes:

1)gem-car: Indicates the rate limitation mode based on the GEM port of the T-CONT. Rate limitation is performed on a specified GEM port in the ONT upstream direction. To select the gem-car mode, set gem add to gem-car. The maximum traffic is determined by the DBA profile bound to the GEM port. If a T-CONT contains multiple GEM ports, the scheduling mechanism of packets between multiple GEM ports depends on the default scheduling mechanism of the ONT.

2)flow-car: Indicates the rate limitation mode based on traffic streams of a GEM port. Rate limitation is performed on a specified traffic stream in the ONT upstream direction. To select the flow-car mode, set gem mapping to flow-car. The maximum traffic is determined by the DBA profile bound to the traffic stream. Flow-car is more specific than gem-car. After rate limitation based on traffic streams is performed, traffic is scheduled in the T-CONT queue. The scheduling mechanism depends on the default scheduling mechanism of the ONT. Before configuring the flow-car, make sure that the required traffic profile is created by running the traffic table ip command.

3)priority-queue: Indicates the PQ mode based on the GEM port of the T-CONT. Traffic is scheduled based on PQ between multiple GEM ports in the ONT upstream direction. To select priority-queue mode, set gem add to priority-queue. By default, the system supports eight (0–7) queues. Queue 7 has the highest priority and services of queue 7 are preferentially scheduled. The maximum traffic is determined by the DBA profile to which the T-CONT is bound.

5. Run the commit command to make the profile configuration take effect. The configuration of the line profile takes effect only after you run this command.

Thanks!
