Wireless Configuration

5. Configure the following parameters in respect to the intended WLAN Downstream Rate Limit, or
traffic from wireless clients to associated Access Point radios:
Video Traffic Set a percentage value for 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%.
Voice Traffic Set a percentage value for 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%.
Enable 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.
Rate 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 5000 kbps.
Maximum Burst
Size
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.
