No proposal is chosen - Payload=PROPOSAL; IKE packet dropped.IKE包 到达时，它没有包含任何被接收方接受的提议（proposal）。在这种情况下，IKE包会被丢弃。
在IKE协商过程中，每一方都会发送一个或多个提议，这些提议描述了它们希望如何加密、认证或处理数据。如果接收方没有选择任何提议，可能是因为提议无效或不被支持，或者是因为配置错误。
解决这个问题通常需要检查和调整IKE配置，确保双方都支持相同的加密和认证算法，并且都正确配置了所有必要的参数。在某些情况下，可能需要升级或更改软件或硬件来支持更新的、更安全的协议或算法。

ipsec vpn中断可能有以下几种原因：
- IKE协商过程中，双方的安全参数不匹配，导致无法选择合适的提议。您可以检查双方的预共享密钥、加密算法、认证算法、DH组等是否一致12。
- IKE协商过程中，双方的身份类型或身份信息不匹配，导致无法验证对方的身份。您可以检查双方的身份类型（IP地址、域名、邮箱等）和身份信息（具体的值）是否一致34。
- IKE协商过程中，双方的网络环境不稳定，导致报文丢失或延迟。您可以检查双方的网络连通性，是否有防火墙或NAT设备阻断或修改报文5 。
您的告警信息显示，IKE协商过程中，没有选择合适的提议，这可能是由于第一种或第二种原因导致的。您可以使用 display ike proposal 命令查看本地的IKE提议配置，与对端的配置进行对比，找出不一致的地方，并进行修改。您还可以使用 display ike sa 命令查看IKE SA的状态，如果状态为MM_NO_STATE，说明IKE协商没有开始或已经失败。

您好，请知：
IPSEC VPN故障排查：
1、检查公网地址的连通性
2、检查ipsec acl是否配置正确（两端ACL以互为镜像的方式配置）
3、检查ike keychain/ike profile 协商参数配置是否正确（工作模式、keychain、identity、本端/对端隧道地址或隧道名称、NAT穿越功能v7自适应）
4、检查ipsec proposal（v5平台） /ipsec transform-set（v7平台）参数两端是否一致（封装模式、安全协议、验证算法、加密算法）
5、检查设备是否创建ipsec策略，并加载协商参数（acl、ike profile 、ipsec transform-set、对端隧道IP）
6、检查ipsec策略是否应用在正确的接口上
IPSEC排查命令：
1、disp ipsec policy
2、disp acl
3、dis cu conf ike-profile
4、dis cu conf ike-keychain
5、display ike proposal
6、display ipsec transform-set
7、disp ike sa (verbose)
8、disp ipsec sa
9、reset ipsec sa
10、reset ike sa
