问题描述

一个集群端口关闭：

::> network port show

Node: A Speed(Mbps) Health Port IPspace Broadcast Domain Link MTU Admin/Oper Status --------- ------------ ---------------- ---- ---- ----------- -------- e0a Cluster Cluster up 9000 auto/10000 healthy e0b Cluster Cluster down 9000 auto/- - ...

Node: B Speed(Mbps) Health Port IPspace Broadcast Domain Link MTU Admin/Oper Status --------- ------------ ---------------- ---- ---- ----------- -------- e0a Cluster Cluster up 9000 auto/10000 healthy e0b Cluster Cluster down 9000 1000/- - ... 28 entries were displayed.

EMS日志会频繁显示端口链路关闭或闪烁：
