Cisco는 전 세계 사용자에게 다양한 언어로 지원 콘텐츠를 제공하기 위해 기계 번역 기술과 수작업 번역을 병행하여 이 문서를 번역했습니다. 아무리 품질이 높은 기계 번역이라도 전문 번역가의 번역 결과물만큼 정확하지는 않습니다. Cisco Systems, Inc.는 이 같은 번역에 대해 어떠한 책임도 지지 않으며 항상 원본 영문 문서(링크 제공됨)를 참조할 것을 권장합니다.

소개

이 문서에서는 TACACS+로 PPP(Point-to-Point Protocol) 콜백을 수행하는 라우터 및 AAA 서버의 컨피그레이션 예를 보여줍니다. AAA 서버 또는 Windows 2000 클라이언트에서 지정한 콜백 번호를 사용하는 두 가지 예가 포함되어 있습니다.

  • 로컬 인증 및 콜백으로 초기 테스트를 수행합니다(aaa new-model 명령 제거). 콜백이 로컬 인증과 작동하지 않을 경우 TACACS+와 작동하지 않습니다. 로컬 인증 사용 방법에 대한 예는 라우터와 Windows PC 간의 MS 콜백 구성을 참조하십시오.

  • 콜백 없이 TACACS+로 추가 PPP 인증 테스트를 수행합니다. 사용자가 콜백 없이 인증 및/또는 권한 부여에 실패할 경우 인증 및 권한 부여가 콜백과 함께 작동하지 않습니다.

  • 콜백에 대한 로컬 인증 및 TACACS+를 통한 PPP 인증이 작동하면 라우터의 로컬 사용자(예: 콜백 다이얼 문자열)의 정보를 서버의 사용자 프로필에 추가합니다.

참고: 이러한 테스트의 클라이언트는 PPP 연결을 위해 평소와 같이 설정된 Windows 2000 Professional 클라이언트(DUN)이며, Microsoft Callback 설정은 "서버가 제공하는 경우 전화 걸기 중에 확인"입니다. Microsoft 콜백은 Cisco IOS® Software 릴리스 11.3.2.T 이상에서 지원됩니다.

서버 지정 번호의 PPP 콜백

서버 컨피그레이션

다음은 AAA 서버에서 지정한 전화 번호로 PPP 콜백을 위한 AAA 서버 컨피그레이션입니다.

서버 설정 - Windows용 Cisco Secure ACS

  • 사용자 및 그룹에 대한 LCP 옵션을 활성화하려면 인터페이스 구성 화면으로 이동하여 TACACS+(Cisco IOS)를 선택하고, 사용자 및 그룹에 대해 PPP IP 및 PPP LCP 옵션이 선택되어 있는지 확인합니다^.

  • 콜백은 그룹 또는 사용자 설정에서 구성할 수 있습니다.

    • 콜백을 위한 그룹 구성: [그룹 설정] 화면의 [콜백]에서 Windows 데이터베이스 콜백 설정 사용 옵션을 선택합니다(이전 버전의 ACS에서는 이 옵션을 "Microsoft NT 콜백 설정 사용"이라고 함). 그런 다음 PPP IP 및 PPP LCP의 옵션을 확인합니다. 콜백 라인을 선택하고 빈 필드에 84007을 입력합니다.

      그룹의 구성원인 사용자의 경우 [사용자 설정] 화면으로 이동하여 [콜백] 아래에서 [그룹 설정 사용]을 선택합니다. Submit(제출) + Restart(재시작)를 클릭합니다.

    • 콜백을 위한 개별 사용자 구성: User Setup(사용자 설정) 화면의 Callback(콜백)에서 이 번호를 사용하여 Callback(콜백)을 선택하고 빈 필드에 84007을 입력합니다. 그런 다음 PPP IP 및 PPP LCP에 대한 옵션을 확인합니다. Submit + Restart를 클릭합니다.

사용자 지정 번호의 PPP 콜백

이 문서의 앞부분에서는 AAA 서버에 지정된 미리 정의된 번호로 콜백하는 예를 보여 줍니다. 콜백은 콜백 번호를 사용하여 사용자가 지정한 번호에서 수행할 수도 있으며 AAA 서버에서 null로 지정됩니다. 그러면 라우터가 사용자에게 콜백 번호를 묻습니다. 초기 테스트는 지정된 로컬 콜백으로 수행해야 합니다. 액세스 서버와 PC 예제 간의 비동기 PPP 콜백을 참조하고 "callback-dialstring"이 따옴표("")로 지정됩니다.

이 테스트의 클라이언트는 PPP 연결을 위해 평소와 같이 설정된 Windows 2000 Professional 클라이언트였으며, Microsoft Callback은 "아래 번호로 다시 전화 주십시오."로 설정되었습니다.

참고: 표시되는 네트워크 다이어그램 및 라우터 컨피그레이션은 여기에서 설명하는 콜백 컨피그레이션에 적용됩니다.

    • 콜백을 위한 그룹 구성: Group Setup(그룹 설정) 화면의 Callback(콜백)에서 콜백 번호를 지정하는 전화 접속 클라이언트에 대한 옵션을 선택합니다. 그런 다음 PPP IP 및 PPP LCP의 옵션을 확인합니다.

      그룹의 구성원인 사용자의 경우 [사용자 설정] 화면으로 이동하여 [콜백] 아래에서 [그룹 설정 사용]을 선택합니다. Submit(제출) + Restart(재시작)를 클릭합니다.

    • 콜백을 위한 개별 사용자 구성: User Setup(사용자 설정) 화면의 Callback(콜백)에서 콜백 클라이언트에서 콜백 번호를 지정하는 옵션을 선택합니다. 그런 다음 PPP IP 및 PPP LCP의 옵션을 확인합니다. Submit + Restart를 클릭합니다.
