vht mcs-map

vht mcs-map

Function

The vht mcs-map command configures the maximum MCS value corresponding to a specific number of 802.11ac spatial streams in the 5G radio profile.

The undo vht mcs-map command restores the default maximum MCS value corresponding to a specific number of 802.11ac spatial streams in the 5G radio profile.

By default, the maximum MCS value of the 802.11 ac radios is 9 in the 5G radio profile.

Format

vht mcs-map nss nss-value max-mcs max-mcs-value

undo vht mcs-map

Parameters

Parameter

Description

Value

nss nss-value Specifies the number of spatial streams. The value is an integer ranging from 1 to 8.
max-mcs max-mcs-value Specifies the maximum MCS value corresponding to a specific number of spatial streams. The value is an integer ranging from 7 to 9.

Usage Guidelines

Usage Scenario

Rates of 802.11ac radios depend on the index value of Modulation and Coding Scheme (MCS). A larger MCS value indicates a higher transmission rate.

  • If nss-value is equal to or larger than the actual number of spatial streams supported by an AP, the maximum MCS value corresponding to all spatial streams of the AP is max-mcs-value.

  • If nss-value is smaller than the actual number of spatial streams supported by an AP, only the maximum MCS value of configured spatial streams is max-mcs-value. The maximum MCS value of the other spatial streams does not take effect.

    For example, if nss-value is 2, and the AP supports 3 spatial streams. Only the maximum MCS value of spatial stream 1 and spatial stream 2 is max-mcs-value, and that of spatial stream 3 does not take effect.

Precautions

This configuration applies only to STAs associated with an RU in 802.11ac/11ax mode but does not take effect on STAs associated with the AP in other modes.

Example

# Configure the maximum MCS value 8 for 802.11ac radios with two spatial streams in the 5G radio profile.
