Frame Aggregation
Frame aggregation is a process of packaging multiple MAC Protocol Data Units (MPDUs) or MAC Service Data Units
(MSDUs) together to reduce the overheads where in turn throughput and capacity can be optimized.
Aggregation of MAC Protocol Data Unit (A-MPDU) requires the use of block acknowledgements.
It is recommended to adjust the A-MPDU and A-MSDU settings to the following to optimize the experience with the Cisco DX
Series.

It is recommended to adjust the A-MPDU and A-MSDU settings to the following to optimize the experience with the Cisco DX
Series.
A-MPDU
User Priority 0, 3, 4, 5 = Enabled
User Priority 1, 2, 6, 7 = Disabled
A-MSDU
User Priority 1, 2 = Enabled
User Priority 0, 3, 4, 5, 6, 7 = Disabled
User Priority 0, 3, 4, 5 = Enabled
User Priority 1, 2, 6, 7 = Disabled
A-MSDU
User Priority 1, 2 = Enabled
User Priority 0, 3, 4, 5, 6, 7 = Disabled
In the 7.0.116.0 release for the Cisco Unified Wireless LAN Controller, the default A-MPDU and A-MSDU configuration is the
following.
A-MPDU
User Priority 0, 4, 5 = Enabled
User Priority 1, 2, 3, 6, 7 = Disabled
A-MSDU
User Priority 0, 1, 2, 3, 4, 5 = Enabled
User Priority 6, 7 = Disabled
User Priority 0, 4, 5 = Enabled
User Priority 1, 2, 3, 6, 7 = Disabled
A-MSDU
User Priority 0, 1, 2, 3, 4, 5 = Enabled
User Priority 6, 7 = Disabled
Use the following commands to configure the A-MPDU and A-MSDU settings per the Cisco DX Series recommendations.
