| Parameter | Description | Default Value | Value Range |
|---|---|---|---|
| Error Injection | |||
| Enable Error Injection | Enable Error Injection | 0 | 0 – Disable 1 – Enable |
| Rate Limiter | |||
| Enable Rate Limiter 1 | Enable Rate Limiter | 0 | 0 – Disable 1 – Enable |
| Max Token Count 2 | This value sets the maximum number of tokens in the bucket in terms
of Bytes. A value of 1, means 1 byte. This value must be equal to or
greater than Burst Max. Note: Setting a value
between 1 and 2 times the value of Burst Max can result in rates
closest to the expected rates.
|
384 | Burst Max to 4,095 |
| Update Interval 2 | This value sets the number of LBUS clock cycles between additions of
Delta Token Count tokens to the bucket. Note:
AMD recommends setting a value between 8
and 32.
|
16 | 1 to 255 |
| Delta Token Count 2 | This value specifies how many tokens are added to the bucket after each interval. A token here is equal to 1 byte. This value must be greater than 0 and less than or equal to Max Token Count. | 384 | 1 to Max Token Count |
