トラブルシュート

ここでは、設定のトラブルシューティングに使用できる情報を示します。

次のようなコマンドを使用します。

  • clear crypto isakmp sa：フェーズ 1 SA をクリアします。

    caution 注意：clear crypto isakmp sa コマンドは、アクティブな VPN トンネルをすべてクリアするので、運用に重大な影響を及ぼす場合があります。PIX/ASA ソフトウェアのバージョン 8.0(3) 以降からは、clear crypto isakmp sa <peer ip address> コマンドを使用して、個々の IKE SA をクリアできます。8.0(3)よりも前のソフトウェアバージョンでは、vpn-sessiondb logoff tunnel-group <tunnel-group-name>コマンドを使用して、1つのトンネルのIKEおよびIPsec SAをクリアできます。
