6. Configure the following parameters in respect to the WLAN's intended
wireless clients to associated access Point radios:
Enable
Rate
Maximum Burst
Size
7. Set the following Downstream Random Early Detection Threshold
random drop is conducted when the amount of tokens for a traffic stream falls below the set threshold for the selected
WLAN.
Background Traffic
Best Effort Traffic
Video Traffic
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 over the WLAN (from all access categories). Traffic
that exceeds the defined rate is dropped and a log message is generated.
The default setting is 5,000 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 the WLANs wireless client destinations. 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 320 kbytes.
Set a percentage value for WLAN 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%.
Set a percentage value for WLAN best effort traffic in the downstream
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 downstream rate is
known by the network administrator (using a time trend analysis). The
default threshold is 50%.
Set a percentage for WLAN video traffic in the downstream 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 downstream rate is known by the
network administrator (using a time trend analysis). The default threshold
is 25%.
