We apply this severity rating system to each issue addressed in a security bulletin. With regard to bulletins that address multiple vulnerabilities, the overall bulletin severity will reflect the highest severity issue addressed in the bulletin.
AAA accounting has the same rules as authentication and authorization: You must first define a named list of accounting methods. Then apply that list to one or more interfaces (except for the the default method list). The first listed method is used, if it fails to respond, the second one is used and so on.
