适用场景

  • ONTAP 9
  • 有交换机集群配置(包括MetroCluster IP)
  • 运行 EFOS 固件版本 <3.9 的 BES-53248 交换机
  • Cisco 发现协议( CDP )
  • ONTAP 集群会话管理器( CSM )

问题描述

  • ONTAP 事件日志记录了 CSM-mismatchRemoteDevice 错误事件:

Thu Feb 17 11:52:05 +0100 [node-01: client_common_RPC: csm.mismatchRemoteDevice:error]: CSM connection between source LIF 1023 and destination address 169.254.13.13 might not be optimal for session 00001111deadbeef. The source is currently connected to - remote device and the destination is currently connected to myONTAPCluster remote device.

  • 上述错误中引用的 IP 地址,即169.254.13.13,是来自此集群中另一节点的集群 LIF
  • 报告上述错误事件的受影响节点 Csum Errors 会显示在 CDP 节点统计信息中
  • 重置 CDP 节点统计信息后 Packets ,计数器会在每个集群网络端口上每分钟增加 1 个数据包, Csum Errors 同时也会同时增加
