Customer is using PEAP and wants to enable Fast Reconnect. There is a setting on the Cisco ACS and the customer states that it must also be set on the mobile device. In an old document from 2006, it does state that Fast Reconnect must be set on both the Radius/ACS and the wireless client. So my question is, does our newer devices have this option? Is it done through a third party supplicant? Customer is testing MC9190s. What is the difference between PEAP Fast Reconnect and CCKM (CCX)?
