Updated: April 10, 2026

Want to summarize with AI?

Configure maximum modulation coding scheme (MCS) index using CLI commands.

Configure the maximum MCS index to optimize wireless performance and data transmission rates.

The maximum MCS index determines the highest modulation and coding scheme that can be used for wireless transmission. You can set this value manually or allow automatic configuration.

Procedure

Configure the maximum MCS index using the following CLI command:

Example:

Device# configure dot11radio <interface> mcs <maxmcs>

Set maximum MCS index in integer or string AUTO. For AUTO, the background process automatically configures the maxmcs.

Valid values are from 0 to 11 or AUTO.

Note

If High Efficiency mode is disabled, set the MCS index value ranging from 0 to 9. If High Efficiency mode is enabled, set the MCS index value as 10 or 11.
