configured respectively. And authorization method can be any one or combination of

Local, RADIUS or TACACS. When login method is configuration in combination, the

preference goes from left to right. If the users have passed the authorization method,

authorization method of lower preferences will be ignored. To be mentioned, if the user

receives corresponding protocol’s answer whether refuse or incept, it will not attempt the

next authorization method; it will attempt the next authorization method if it receives

configuration method can be used. And TACACS server should be configured before the

TACACS configuration method can be used.
