问题描述

持续闪烁的链路会使集群网络上的网络端口关闭：

[Node-01: kernel: netif.linkDown:info]: Ethernet e0c: Link down, check cable.

[Node-01: vifmgr: vifmgr.portdown:notice]: A link down event was received on node Node-01, port e0c.

[Node-01: vifmgr: vifmgr.clus.linkdown:EMERGENCY]: The cluster port e0c on node Node-01 has gone down unexpectedly.

[Node-01: vifmgr: vifmgr.portup:notice]: A link up event was received on node Node-01, port e0c.

[Node-01: vifmgr: vifmgr.port.monitor.failed:error]: The "link_flapping" health check for port e0c (node Node-01) has failed. The port is operating in a degraded state.

[Node-01: vifmgr: callhome.clus.net.degraded:alert]: Call home for CLUSTER NETWORK DEGRADED: Frequent Link Flapping - Cluster port e0c on node Node-01 has experienced multiple link down notifications.

由于端口降级、正在移动多条有关此文件的消息。示例：

[Node-01: vifmgr: vifmgr.portDeg.lifMoved:notice]: LIF Node-01_clus2 (on virtual server 1234567890), IP address 169.254.202.133, is being moved to node Node-01, port e0d from node Node-01, port e0c because the port's health status is in a degraded state.

端口运行状况降级原因是使用命令进行了link_flp操作 network port show
