Want to summarize with AI?

Configure the maximum number of spatial streams (NSS) index using CLI commands.

Configure the maximum number of spatial streams (NSS) index to optimize wireless performance based on device capabilities and antenna configuration.

The NSS index determines the maximum number of spatial streams that can be used for wireless communication. This setting can be configured manually with specific values or set to AUTO for automatic configuration.

Procedure

Configure the maximum number of spatial streams index using the following command:

Example:

Device# configure dot11radio <interface> spatial-stream <maxnss>

Set maximum spatial stream number in integer or string AUTO. For AUTO, the background process automatically configures the maxnss.

Valid values range from 1 to 4 or AUTO.

Note

Catalyst IW9165 supports up to two spatial streams and Catalyst IW9167 supports up to four spatial streams. The maximum number of spatial streams configured must be same or less than the number of antennas enabled.
