适用于

  • ONTAP 9.2+
  • 集群管理网络

问题

  • 从 ONTAP 9.1P16 升级到 9.3P21 后管理接口无法访问
  • Admin SVM 有两个接口 mgmtintercluster
    • Mgmt LIF 配置了 IP 地址 10.0.0.5/24,位于端口 e0M
    • Intercluster LIF 配置了 IP 地址   172.16.1.8/24,位于端口 e0a
    • 客户端与 intercluster LIF 处于同一子网,IP 为 172.16.1.5/24
    • SVM 配置的唯一静态路由是指向 10.0.0.1/24 的默认路由
    • 客户端连接到远离其子网的 mgmt LIF(位于 e0M),向 10.1.1.254 发送数据包
    • 当 ONTAP 查找此流量的返回路由时,它会注意到通过配置了 172.16.1.5 (intercluster) LIF172.16.1/24 subnet 上的端口 e0a 有一条直连路由
    • 返回流量将从节点的 e0b 端口直接发送到客户端
