User logout procedures:
There are two types of user logout: one is the logout detected by the access device, because the user's
time is out and the flow is used up or the link is interrupted. The other one is that the logout detected by
Portal Server because the user triggers the logout application through a logout page or the keep-alive
page is invalid.
12) Scenario 1: The access device detects the user's logout, and informs the Portal Server, and then
the server deletes the user information (through SNMP protocol). The Portal Server will then inform
the user through a logout page.
