편견 없는 언어

본 제품에 대한 문서 세트는 편견 없는 언어를 사용하기 위해 노력합니다. 본 설명서 세트의 목적상, 편견 없는 언어는 나이, 장애, 성별, 인종 정체성, 민족 정체성, 성적 지향성, 사회 경제적 지위 및 교차성에 기초한 차별을 의미하지 않는 언어로 정의됩니다. 제품 소프트웨어의 사용자 인터페이스에서 하드코딩된 언어, RFP 설명서에 기초한 언어 또는 참조된 서드파티 제품에서 사용하는 언어로 인해 설명서에 예외가 있을 수 있습니다. 시스코에서 어떤 방식으로 포용적인 언어를 사용하고 있는지 자세히 알아보세요.

이 번역에 관하여

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 5508 Series WLC가 모빌리티 앵커 역할을 하고 Catalyst 3850 Series 스위치가 클라이언트의 모빌리티 외부 컨트롤러 역할을 하는 새로운 모빌리티 구축 설정에서 무선 클라이언트 게스트 앵커에 대해 5508/5760 Series WLC(Wireless LAN Controller) 및 Catalyst 3850 Series 스위치를 구성하는 방법에 대해 설명합니다. 또한 Catalyst 3850 Series Switch가 Mobility Agent 역할을 하여 Catalyst 3850 Series Switch가 Access Point(AP) 라이센스를 획득하는 5760 Series WLC에서 Mobility Controller 역할을 합니다.

사전 요구 사항

요구 사항

이 컨피그레이션을 시도하기 전에 다음 항목에 대해 알고 있는 것이 좋습니다.

  • Cisco IOS® GUI 또는 CLI(Converged Access 5760 및 3650 Series WLC 및 Catalyst 3850 Series 스위치 포함)
  • 5508 Series WLC를 통한 GUI 및 CLI 액세스
  • SSID(Service Set Identifier) 컨피그레이션
  • 웹 인증

사용되는 구성 요소

이 문서의 정보는 다음 소프트웨어 및 하드웨어 버전을 기반으로 합니다.

  • Cisco 5760 릴리스 3.3.3(NGWC[Next Generation Wiring Closet])
  • Catalyst 3850 Series 스위치
  • Cisco 5508 Series WLC 릴리스 7.6.120
  • Cisco 3602 Series Lightweight AP
  • Cisco Catalyst 3560 Series Switches

이 문서의 정보는 특정 랩 환경의 디바이스를 토대로 작성되었습니다. 이 문서에 사용된 모든 디바이스는 초기화된(기본) 컨피그레이션으로 시작되었습니다. 현재 네트워크가 작동 중인 경우, 모든 명령어의 잠재적인 영향을 미리 숙지하시기 바랍니다.

구성

참고: 이 섹션에서 사용된 명령에 대한 자세한 내용을 보려면 Command Lookup Tool(등록된 고객만 해당)을 사용하십시오.

네트워크 다이어그램

5508 Series WLC는 앵커 컨트롤러 역할을 하며, Catalyst 3850 Series 스위치는 Foreign Controller 및 Mobility Controller 5760에서 라이센스를 얻은 Mobility Agent 역할을 합니다.

참고: 네트워크 다이어그램에서 5508 Series WLC는 앵커 컨트롤러, 5760 Series WLC는 모빌리티 컨트롤러, Catalyst 3850 Series 스위치는 모빌리티 에이전트 및 외부 WLC 역할을 합니다. 어느 시점에서든 Catalyst 3850 Series Switch의 Anchor Controller는 5760 Series WLC 또는 5508 Series WLC입니다. 이중 앵커가 작동하지 않기 때문에 두 앵커가 동시에 앵커가 될 수 없습니다.

설정

이 구성에는 세 가지 부분이 포함됩니다.

1부 - 5508 앵커 WLC의 컨피그레이션

2부 - 5508/5760 Series WLC와 Catalyst 3850 Series Switch 간의 Converged Access Mobility Configuration

3부 - Foreign Catalyst 3850 Series 스위치의 구성

1부 - 5508 앵커 WLC의 컨피그레이션

  1. 5508 Series WLC에서 새 무선 LAN(WLAN)을 생성하려면 WLAN(WLAN) > New(새로 만들기)에 마우스를 놓습니다.



  2. 레이어 3 보안을 구성하려면 WLAN > WLAN Edit > Security > Layer 3 enabled Web-authentication 위에 마우스 커서를 놓습니다.



  3. 5508 Series WLC를 앵커로 추가하려면 WLAN mobility Anchor 컨피그레이션 창 아래에서 앵커 주소를 로컬로 설정합니다.



  4. Security(보안) > Webauth(웹 인증) > Webauth(웹 인증) 페이지 위에 마우스 커서를 올려 놓으면 클라이언트 인증에 사용할 웹 인증 페이지를 구성할 수 있습니다.

    이 예에서는 WLC 내부 웹 인증 페이지가 선택됩니다.



  5. 로컬 네트워크 사용자를 생성합니다. 이 사용자 이름/비밀번호 쌍은 Webauth 페이지에 프롬프트가 표시되면 사용자가 사용합니다.

2부 - 5508/5760 Series WLC와 Catalyst 3850 Series Switch 간의 통합 액세스 모빌리티 구성

  1. 5508 Series WLC에서 5760 Series WLC를 모빌리티 피어로 추가합니다.



  2. 5760 Series WLC에서 모빌리티 컨트롤러 역할을 하면서 5508 Series WLC를 모빌리티 피어로 추가합니다.



  3. 이 단계는 매우 중요합니다! Mobility Management(모빌리티 관리) 아래의 Switch Peer Group(스위치 피어 그룹) 탭 아래에 있는 5760 Series WLC에서 Catalyst 3850 Series 스위치를 모빌리티 에이전트로 추가합니다.



  4. Catalyst 3850 Series Switch에서 5760 Series WLC를 모빌리티 컨트롤러로 추가합니다. 이렇게 하면 Catalyst 3850 Series Switch가 Mobility Controller 5760에서 AP 클라우드 라이센스를 획득합니다.

3부: Foreign Catalyst 3850 Series 스위치의 구성

  1. Catalyst 3850 Series 스위치에서 정확한 SSID/WLAN을 구성하려면 GUI > Configuration > Wireless > WLAN > New 위에 마우스 커서를 올려 놓습니다.



  2. 레이어 3 보안을 구성하려면 WLAN > WLAN Edit > Security > Layer 3 enabled Web-authentication 위에 마우스 커서를 놓습니다.



  3. WLAN Mobility Anchor 컨피그레이션에서 5508 Series WLC IP 주소를 앵커로 추가합니다

다음을 확인합니다.

구성이 올바르게 작동하는지 확인하려면 이 섹션을 활용하십시오.

클라이언트를 WLAN CUWN(Cisco Unified Wireless Network)에 연결합니다. 워크플로는 다음과 같습니다.

  1. 클라이언트가 IP 주소를 수신합니다.
  2. 클라이언트가 브라우저를 열고 웹 사이트에 액세스합니다.
  3. 클라이언트에서 보낸 첫 번째 TCP 패킷은 WLC에 의해 하이재킹되며, WLC는 Webauth 페이지를 가로채서 전송합니다.
  4. DNS가 올바르게 구성된 경우 클라이언트는 Webauth 페이지를 가져옵니다.
  5. 인증하려면 클라이언트가 사용자 이름/비밀번호를 제공해야 합니다.
  6. 인증에 성공하면 클라이언트가 원래 액세스 페이지로 리디렉션됩니다.

  7. 클라이언트가 올바른 자격 증명을 제공하면 클라이언트가 인증을 전달합니다.

문제 해결

컨피그레이션의 문제를 해결하려면 게스트 앵커 역할을 하는 5508 Series WLC에 다음 디버그를 입력합니다.

Debug Client 
       
       
Debug web-auth redirect enable mac

예를 들면 다음과 같습니다.

Debug Client 00:17:7C:2F:B6:9A
Debug web-auth redirect enable mac 00:17:7C:2F:B6:9A

show debug

다음은 클라이언트 측 패킷 캡처입니다.

클라이언트가 IP 주소를 가져옵니다.

클라이언트가 브라우저를 열고 www.facebook.com을 입력합니다.

WLC는 클라이언트의 첫 번째 TCP 패킷을 가로채고 가상 IP 주소 및 내부 Webauth 페이지를 푸시합니다.

웹 인증에 성공하면 나머지 워크플로가 완료됩니다.
