Guard interval values include:

  • 3200: Configures 3200 ns guard interval (supported only in HE mode).

  • 1600: Configures 1600 ns guard interval (supported only in HE mode).

  • 400: Configures 400 ns guard interval (supported in HT and VHT modes).

Step 2

Use the show dot11Radio interface show command to verify the configuration.

Example:

Device# show dot11Radio 1 show
