由于集群端口/SFP连接错误、报告集群网络已降级警报
适用场景
- ONTAP 9
- 集群网络
问题描述
- 多次收到以下集群网络降级AutoSupport 通知：
HA Group Notification (CLUSTER NETWORK DEGRADED) ALERT
- 除IFSTAT输出的"接收"部分所示的一个集群端口外、所有节点的集群端口上都报告了多个错误。
system health alert show您可能会在命令输出中看到集群交换机运行状况已降级- 存在多个错误的集群端口(可能会同时显示CRC错误、错误符号、非法符号等)：

- 单个集群端口无错误：
clustershell::>system node run -node <nodename> -command ifstat -a

- 您可能会在EMS日志和生成的运行状况警报中看到以下消息
netif.linkErrors: Excessive link errors on network interface e2c. Might indicate a bad cable, switch port, or NIC, or that a cable connector is not fully inserted in a socket. On a 10/100 port, might indicate a duplex mismatch.
- 可能会针对唯一节点端口的已连接交换机端口生成以下警报、但未收到CRC错误：
