Maximum Burst Size
Set a maximum burst size from 2 - 1024 kbytes. The smaller the burst, the less likely the
receive packet transmission will result in congestion for the Mesh Points 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 64 kbytes.
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%.
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%.
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%.
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.
Select this radio button to enable rate limiting for data transmitted from the client to its
associated access point radio and connected wireless controller. Enabling this option does
not invoke client rate limiting for data traffic in the receive direction. This feature is
disabled by default.
Define an transmit rate limit from 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.
Set a maximum burst size from 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.
