early random drop is conducted when the amount of tokens for a traffic stream falls below the set threshold for
wireless client traffic.
Background Traffic
Set a percentage value for client video traffic in the upstream 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 upstream rate is known by the
network administrator (using a time trend analysis). The default threshold
is 25%.
Set a percentage value for WLAN voice traffic in the upstream 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 upstream rate is known
by the network administrator (using a time trend analysis). The default
threshold is 0%.
Select the Enable radio button to enable rate limiting for data transmitted
from Access Point radios to associated wireless clients. Enabling this
option does not invoke rate limiting for data traffic in the upstream
direction. This feature is disabled by default.
Define an upstream rate limit between 50 - 1,000,000 kbps.This limit
constitutes a threshold for the maximum the number of packets
transmitted or received from clients. Traffic that exceeds the defined rate
is dropped and a log message is generated. The default setting is 1,000
kbps.
Set a maximum burst size between 2 - 1024 kbytes. The smaller the burst,
the less likely the downstream packet transmission will result in
congestion for wireless client traffic. By trending the typical number of
ARP, broadcast, multicast and unknown unicast packets over a period of
time, the average rate for each access category can be obtained. Once a
baseline is obtained, administrators should then add a minimum of a 10%
margin to allow for traffic bursts at the site. The default burst size is 64
kbytes.
Downstream Random Early Detection Threshold
Set a percentage value for client background traffic in the downstream
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 downstream rate is known by the network administrator
(using a time trend analysis). The default threshold is 50%.
Downstream Rate Limit for wireless client
