rate-limit [client|wlan] [from-air|to-air] {red-threshold [background <0-100>|
best-effort <0-100>|video <0-100>|voice <0-100>]}
Usage Guidelines:
The following information should be taken into account when configuring rate limits:
• Background traffic consumes the least 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).
• Best effort traffic consumes little bandwidth, so this value can be set to a lower value once a
general upstream rate is known by the network administrator (using a time trend analysis).
• 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).
• 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).

rate-limit Configures traffic rate limit parameters
client Configures traffic rate limiting parameters on a per-client basis
wlan Configures traffic rate limiting parameters on a per-WLAN basis
from-air Configures traffic rate limiting from a wireless client to the network
to-air Configures the traffic rate limit from the network to a wireless client
red-threshold Configures random early detection threshold values for a designated traffic class
background <0-100> The following is common to the ‘from-air’ and ‘to-air’ parameters:
Optional. Sets a percentage value for background traffic in the upstream or downstream direction.
Background traffic exceeding the defined threshold is dropped and a log message is generated. The
default threshold is 50% for traffic in both directions.
best-effort <0-100> The following is common to the ‘from-air’ and ‘to-air’ parameters:
Optional. Sets a percentage value for best effort traffic in the upstream or downstream direction. Best
effort traffic exceeding the defined threshold is dropped and a log message is generated. The default
threshold is 50% for traffic in both directions.
video <0-100> The following is common to the ‘from-air’ and ‘to-air’ parameters:
Optional. Sets a percentage value for video traffic in the upstream or downstream direction. Video traffic
exceeding the defined threshold is dropped and a log message is generated. The default threshold is
25% fro traffic in both directions.
voice <0-100> The following is common to the ‘from-air’ and ‘to-air’ parameters:
Optional. Sets a percentage value for voice traffic in the upstream or downstream direction. Voice traffic
exceeding the defined threshold is dropped and a log message is generated. The default threshold is 0%
for traffic in both directions. 0% means no early random drops will occur.
