The he mcs-map command configures the number of 802.11ax spatial streams and the Modulation and Coding Scheme (MCS) of the spatial streams in an SSID profile.
The undo he mcs-map command restores the default number of 802.11ax spatial streams and the default MCS of the spatial streams in an SSID profile.
By default, the number of spatial streams sent and received in 802.11ax is 8, and the MCS of the spatial streams is 11 in an SSID profile.

|---|---|---|
tx |
Indicates the sent data. |

rx |
Indicates the received data. |

nss nss-value |
Specifies the number of spatial streams. |
The value is an integer that ranges from 1 to 8. |
map mcs-value |
Specifies the MCS of the spatial streams. |
The value can be 7, 9, or 11. |
Usage Scenario
The rate of an 802.11ax-capable AP depends on the index value of the MCS. A larger MCS indicates a higher transmission rate.
When the value of nss-value is greater than or equal to the number of spatial streams actually supported by an AP, the MCS value corresponding to all the spatial streams of the AP is the value of mcs-value.
When the value of nss-value is smaller than the number of spatial streams actually supported by an AP, only the MCS value corresponding to the spatial streams on the AP is the value of mcs-value, and the maximum MCS value corresponding to other spatial streams does not take effect.
For example, if the value of nss-value is 2, and the AP supports three spatial streams, only the MCS value corresponding to spatial streams 1 and 2 is the value of mcs-value, and the MCS value corresponding to spatial stream 3 does not take effect.
Precautions
This configuration takes effect only when the AP communicates with STAs through 802.11ax.
