A method is a configured server group. Up to four methods can be specified and
placed in the list in the order you want the router to use them. The router will
attempt the first method in the list. If the authentication request receives a PASS
or a FAIL response, the router does not query further. If the router does not receive
a response by using the first method, it uses the next method in the list, and
continues to the end of the list until it receives a PASS or a FAIL response.
Click this button to add a method to the list. If there are no configured server
groups to add, you can configure a server group in the window displayed.
Click this button to delete a method from the list.
The router attempts the methods in the order they are listed in this window. Click
Move Up to move a method up the list. Click Move Down to move a method
further down the list.
The method "none" will always be last in the list. No other method in the list can
be moved below it. This is an IOS restriction. IOS will not accept any method
name after the method name "none" has been added to a Method List.
