6. Set the following Downstream Random Early Detection Threshold settings for each access
category. An early random drop is done when the amount of tokens for a traffic stream falls below the
set threshold.
7. Select OK when completed to update this WLAN’s QoS rate limit settings. Select Reset to revert the
screen back to its last saved configuration.
6.2.3 Configuring a WLAN’s QoS Wireless Client Rate Limit Settings
Wireless clients can also have QoS rate limit settings defined in both the upstream and downstream
direction.
To configure a QoS rate limit configuration for wireless clients:
1. Select Configuration > Wireless > WLAN QoS Policy to display existing QoS policies available to
WLANs.
2. Either select the Add button to define a new WLAN QoS policy, or select an existing WLAN QoS policy
and select Edit to modify its existing configuration.
3. Select the Wireless Client Rate Limiting tab.
Background Traffic Set a percentage value for 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%.
Best Effort Traffic Set a percentage value for 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%.
Video Traffic Set a percentage value for 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%.
Voice Traffic Set a percentage value for voice traffic in the downstream 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%. 0% means no early random drops will occur.
