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 IP
Phone 8800 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
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
Use the following commands to configure the A-MPDU and A-MSDU settings per the Cisco IP Phone 8800 Series
recommendations.
In order to configure the 5 GHz settings, the 802.11a network will need to be disabled first, then re-enabled after the changes
are complete.

config 802.11a 11nSupport a-msdu tx priority 7 disable
In order to configure the 2.4 GHz settings, the 802.11b/g network will need to be disabled first, then re-enabled after the
changes are complete.
