These details include the session_id, external IP address of the VPN client, and the IP address of the ASA. The ISE uses the session_id in order to identify that session. The ASA also sends periodic interim account information, where the most important attribute is the Framed-IP-Address with the IP that is assigned to the client by the ASA ( 10.10.10.10 in this example).
