•
When a preconfigured interval of time has elapsed since the first frame - of a set of frames
to be aggregated - was received.
•
When a preconfigured interval has elapsed since the last frame, not necessarily the final
frame, - of a set of frames to be aggregated - was received.
In this enhancement to the standard frame aggregation, the time delay for aggregation is set
individually for each traffic class. For example, voice traffic might not be aggregated but sent
immediately, whereas, background data traffic is set a time delay for aggregating frames and these
aggregated frames are sent.

Radio QoS Configuration and Deployment Considerations
Before defining a radio QoS policy, refer to the following deployment guidelines to ensure the
configuration is optimally effective:
•
To support QoS, each multimedia application, wireless client and WLAN is required to support
WMM.
•
WMM enabled clients can co-exist with non-WMM clients on the same WLAN. Non-WMM
clients are always assigned a best effort access category.
•
Brocade recommends default WMM values be used for all deployments. Changing these
values can lead to unexpected traffic blockages, and the blockages might be difficult to
diagnose.
•
Overloading an access point radio with too much high priority traffic (especially voice)
degrades the overall service quality for all users.
•
TSPEC admission control is only available with newer voice over WLAN phones. Many legacy
voice devices do not support TPSEC or even support WMM traffic prioritization.
19.
Smart Aggregation
Select to enable Smart Aggregation and dynamically set the time when an aggregated frame is
transmitted.
Max Delay for Best Effort
Specify the maximum time in milliseconds to delay best effort traffic. The default setting is 150
millisecond.
Max Delay for Background
Specify the maximum time in milliseconds to delay background traffic. The default setting is 250
millisecond.
Max Delay for Streaming
Video
Specify the maximum time in milliseconds to delay streaming video traffic. The default setting is
150 millisecond.
Max Delay for Video
Conferencing
Specify the maximum time in milliseconds to delay video conferencing traffic. The default setting is
40 millisecond.
Max Delay for Voice
Specify the maximum time in milliseconds to delay voice traffic. The default setting is 0 millisecond.
Minimum frames per
Aggregate limit
Specify the minimum number of frames to aggregate in a frame before it is transmitted. The default
setting is 8 frames.
Max Mesh Links
Specify the maximum number of mesh links for Smart Aggregation. The default setting is 3.
