Figure 5-18 Advanced DDRS Configuration
The following table lists the Advanced Configuration parameters and their description. Note that these parameters are
read-only and can be configured only through CLI or SNMP.
Parameter Description
Minimum Rate and Represents the minimum and maximum data rate between which the DDRS dynamically
Maximum Rate selects the transmission data rate. These varies depending on the configured Data
Streams, Channel Bandwidth and Guard Interval.
Lower SNR Correction Represents the margin value to be added to the Minimum Required SNR, for the purpose
of removing the data rate from the valid data rate table. Doing so, avoids Hysteresis in the
dynamic data rate.
By default, it is configured to 10 dB.
Upper SNR Correction Represents the margin value to be added to the Minimum Required SNR, for the purpose
of adding the data rate to the valid data rate table. Doing so, avoids Hysteresis in the
dynamic data rate.
By default, it is set to 3 dB.
Rate Increment RTX Represents a threshold for the percentage of retransmissions, below which the rate can be
Threshold increased. By default, it is set to 25%.
: If the percentage of retransmissions is between “Rate Increment RTX Threshold”
and “Rate Decrement RTX Threshold” then the current operation rate is
maintained.
