7. Set the following To Air Downstream Random Early Detection Threshold settings for each
access category. An early random drop occurs when the amount of tokens for a traffic stream
falls below the set threshold.
8. Configure the following parameters in respect to the intended Neighbor Settings From Air
Upstream Rate Limit:
Background Traffic Set a percentage value for background traffic in the receive direction. This is a percentage of the
maximum burst size for low priority traffic. Background traffic exceeding the defined threshold is
dropped and a log message is generated. Background traffic consumes the least bandwidth of any
access category, so this value can be set to a lower value once a general receive rate is known by
the network administrator (using a time trend analysis). The default threshold is 50%.
Best Effort Traffic Set a percentage value for best effort traffic in the receive direction. This is a percentage of the
maximum burst size for normal traffic. Best effort traffic exceeding the defined threshold is
dropped and a log message is generated. Best effort traffic consumes little bandwidth, so this
value can be set to a lower value once a general receive rate is known by the network administrator
(using a time trend analysis). The default threshold is 50%.
Video Traffic Set a percentage value for video traffic in the receive direction. This is a percentage of the
maximum burst size for video traffic. Video traffic exceeding the defined threshold is dropped and a
log message is generated. Video traffic consumes significant bandwidth, so this value can be set to
a higher value once a general receive rate is known by the network administrator (using a time
trend analysis). The default threshold is 25%.
Voice Traffic Set a percentage value for voice traffic in the receive direction. This is a percentage of the
maximum burst size for voice traffic. Voice traffic exceeding the defined threshold is dropped and a
log message is generated. Voice applications consume significant bandwidth, so this value can be
set to a higher value once a general transmit rate is known by the network administrator (using a
time trend analysis). The default threshold is 0%. 0% means no early random drops will occur.
Neighbor Rx Rate Limit Select the radio button to enable rate limiting for data transmitted from the client to its associated
Access Point radio and connected controller or service platform. Enabling this option does not
invoke client rate limiting for data traffic in the receive direction. This feature is disabled by default.
Rate Define an transmit rate limit between 50 - 1,000,000 kbps. This limit constitutes a threshold for
the maximum the number of packets transmitted or received (from all access categories). Traffic
that exceeds the defined rate is dropped by the client and a log message is generated. The default
rate is 1,000 kbps.
Maximum Burst Size Set a maximum burst size between 2 - 1024 kbytes. The smaller the burst, the less likely the
transmit packet transmission will result in congestion for the wireless client. The default burst size
is 64 kbytes.
