2. Make sure that each check box is selected, that Enable Fast Reconnect is
selected, that PEAP and EAP-TLS time outs are set to 120 minutes.
3. Click Submit + Restart.
Note: We highly recommend that you enable all protocols globally. You will
have the opportunity to limit the actual protocol options later when you create
the Network Access Profiles for NAC. If they are not enabled here, they will not
be enabled in the Network Access Profiles.
