The ht a-mpdu max-length-exponent command sets the maximum length of an aggregated MPDU (A-MPDU) on the 802.11n radio. MPDU stands for MAC protocol data unit.
The undo ht a-mpdu max-length-exponent command restores the maximum length of an A-MPDU on the 802.11n radio to the default value.
By default, the index for the maximum length of an A-MPDU is 3. The maximum length of the A-MPDU is 65535 bytes.
This command does not take effect on AirEngine series APs (except the AirEngine 5760-10).

Indicates the index for the maximum length of the A-MPDU. |
The value is an integer that ranges from 0 to 3.

To reduce costs, 802.11n uses frame aggregation technology that aggregates two or more frames into an A-MPDU to transmit.
# Set the index of the maximum length of the A-MPDU to 2 in the 2G radio profile default. The index 2 corresponds to a maximum length of 32767 bytes.
