Log in

Configure the AP radio role to ensure the 6 GHz band remains active after a CAPWAP reset.

This procedure describes how to configure the AP radio role to manual for slot 2. This change ensures that the 6 GHz radio band remains active, even after a CAPWAP reset. If the radio role is set to auto, the AP might revert to the 5 GHz band upon reset.

Before you begin

Ensure you have CLI access to the AP.

Procedure

1.

Verify the current radio role configuration. From the AP CLI, check the current radio configuration for slot 2.

Example:

show capwap client config | i Radio

If the output shows the radio role for slot 2 as auto, proceed to Step 2.

If the output shows the radio role for slot 2 as manual, no further action is required for this setting
2.

Configure the radio role to manual and set the 6 GHz band. Execute these commands on the AP CLI to set the radio role for slot 2 to manual and configure it for the 6 GHz band. This step ensures the controller applies the manual radio role to the AP.

Example:

ap name NAME dot11 dual-band slot 2 shutdown
ap name NAME dot11 dual-band slot 2 radio role manual client-serving
ap name NAME dot11 dual-band slot 2 band 5ghz
ap name NAME dot11 no dual-band slot 2 shutdown
ap name NAME dot11 dual-band slot 2 shutdown
ap name NAME dot11 dual-band slot 2 band 6ghz
