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 Cisco IOS® Easy VPN Remote Hardware Client와 PIX Easy VPN Server 간의 IPSec에 대한 샘플 컨피그레이션을 제공합니다.

참고: Easy VPN Remote 기능은 하드웨어 클라이언트 및 EzVPN 클라이언트라고도 합니다.

Cisco VPN 3000 Concentrator에 연결하기 위해 NEM(Network Extension Mode)에서 Cisco IOS 라우터를 EzVPN으로 구성하는 방법에 대한 자세한 내용은 VPN 3000 Concentrator 컨피그레이션 예를 사용하는 IOS 라우터의 EzVPN을 참조하십시오.

Easy VPN을 사용하여 Cisco PIX/ASA 7.x와 Cisco 871 라우터 간에 IPSec을 구성하는 방법에 대한 자세한 내용은 PIX/ASA 7.x 이상: Easy VPN with Split Tunneling ASA 5500을 서버로, Cisco 871을 Easy VPN Remote Configuration Example을 참조하십시오.

Cisco 7200 라우터를 EzVPN으로, Cisco 871 라우터를 Easy VPN Remote 클라이언트로 구성하는 방법에 대한 자세한 내용은 IOS Router: NEM(Network-Extension Mode) 컨피그레이션 예를 사용하는 Ezvpn(Easy VPN)을 참조하십시오.

사전 요구 사항

요구 사항

문제 해결

이 섹션에서는 컨피그레이션 트러블슈팅에 사용할 수 있는 정보를 제공합니다.

이 문서에 설명된 대로 Easy VPN Remote Hardware Client 및 Easy VPN Server를 설정했지만 여전히 문제가 발생하는 경우 Cisco TAC(Technical Assistance Center)에서 분석할 수 있도록 각 디바이스의 디버그 출력 및 show 명령의 출력을 수집합니다.

트러블슈팅에 대한 자세한 내용은 IP 보안 트러블슈팅 - 디버그 명령 이해 및 사용 및 PIX 트러블슈팅을 참조하여 설정된 IPSec 터널에서 데이터 트래픽을 전달하십시오.

PIX Easy VPN 서버

OIT(Output Interpreter Tool)(등록된 고객만 해당)는 특정 show 명령을 지원합니다. OIT를 사용하여 show 명령 출력 분석을 볼 수 있습니다.

참고: debug 명령을 사용하기 전에 Debug 명령에 대한 중요 정보를 참조하십시오.

  • debug crypto ipsec - 2단계의 IPSec 협상을 표시합니다.

  • debug crypto isakmp - 1단계의 ISAKMP 협상을 표시합니다.
