authentication-mode aaa
user privilege level 3
idle-timeout 0 0
user-interface vty 4 14
user privilege level 3
idle-timeout 0 0
Alarm Information
None
Handling Process
1. Direct configure in the view of the user-interface vty 0 14, and then view the configuration, virtual terminal still divided into user-interface vty 0 3 and user-interface vty 4 14 two parts;
2. In the view of the user-interface vty 4 14, configure the authentication-mode aaa;
3. Re-testing, more user can login.Use “ disp cu” to view related configuration:
user-interface maximum-vty 15
user-interface con 0
user-interface vty 0 14
authentication-mode aaa
user privilege level 3
idle-timeout 0 0
Root Cause
 Configuration issues, user-interface vty 4 14 configure the following configuration without certification;
Suggestions
The key to this problem is that directly configure in the view of the user-interface vty 0 14  is invalid, because the user-interface vty has been divided into two parts, the need to configure these two parts into a consistent, combined to take effect.
