Function
This command is used to query the parameters configured for over-grant
detection on a specified PON port. Over-grant is a situation in which a user
applies for bandwidth excessively higher than the user's allocated bandwidth.
The system supports over-grant detection for such abnormalities. After the
command is executed successfully, the system displays the over-grant parameters
of the specified PON port.
Parameters
| Parameter | Description | Value |
|---|---|---|
| oltid | Indicates the port ID. | Please see Differences Between Shelves. |
Usage Guidelines
-
In the privilege mode or global config mode, run the diagnose command to enter the
Diagnose mode.
- Before running this command, run the transparent on(diagnose) command to enter transparent transmission channel mode.
Example
To query the parameters configured for over-grant detection on PON port 0, do
as follows:
huawei(diagnose)%%emac dba display over-grant-param
{ OLTID:<0..7>[0] }:0
Over Grant Monitoring Param:
The Monitoring Interval : 58
The DBA grant threshold : 0x0 1000000
The utilization threshold : 128
The problem detection limit: 4
System Response
- The system displays the queried result when the command runs successfully.
- The following table describes the parameters in response to this
command.
Parameter Description The Monitoring Interval Indicates the interval between over-grant detections, in the unit of milliseconds. The DBA grant threshold Indicates the over-grant threshold, in the unit of bytes. When a user applies for a bandwidth higher than the threshold bandwidth, it is considered as an over-grant action. The utilization threshold Indicates the minimum expected grant utilization, in the unit of bytes. The problem detection limit Indicates the threshold for triggering over-grant detection. When a user requests excessively high bandwidth for more times than specified by the threshold, the system starts over-grant detection.
