Important Points to Remember Consider the following when creating a user role: • Only the system administrator and user-defined roles inherited from the system administrator can create roles and usernames. Only the system administrator, security administrator, and roles inherited from these can use the role command to modify command permissions. The security administrator and roles inherited by security administrator can only modify permissions for commands they already have access to. • Make sure you select the correct role you want to inherit. NOTE: If you inherit a user role, you cannot modify or delete the inheritance. If you want to change or remove the inheritance, delete the user role and create it again. If the user role is in use, you cannot delete the user role.
