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
