다음과 같이 다음 명령을 사용합니다.

  • clear crypto isakmp sa - 1단계 SA를 지웁니다.

    caution 주의: clear crypto isakmp sa 명령은 침입하므로 모든 활성 VPN 터널이 지워집니다.8.0(3) 버전의 PIX/ASA 소프트웨어부터 clear crypto isakmp sa <peer ip address> 명령을 사용하여 개별 IKE SA를 지울 수 있습니다.8.0(3) 소프트웨어 버전 이전에 vpn-sessiondb logoff tunnel-group <tunnel-group-name> 명령을 사용하여 단일 터널에 대한 IKE 및 IPsec SA를 지울 수 있습니다.
