vht a-mpdu max-length-exponent

vht a-mpdu max-length-exponent

Function

The vht a-mpdu max-length-exponent command sets the maximum length of an aggregated MPDU (A-MPDU) on the 802.11ac radio. MPDU stands for MAC protocol data unit.

The undo vht a-mpdu max-length-exponent command restores the maximum length of an A-MPDU on the 802.11ac radio to the default value.

By default, the index for the maximum length of an A-MPDU is 7. The maximum length of the A-MPDU is 1048575 bytes.

Format

Usage Guidelines

To reduce costs, 802.11ac uses frame aggregation technology that aggregates two or more frames into an A-MPDU to transmit.

Example

# Set the index of the maximum length of the A-MPDU to 2 in the 5G radio profile default. The index 2 corresponds to a maximum length of 32767 bytes.
