适用场景

ONTAP 9.3及更高版本
多模式LACP

问题描述

物理端口已启动、但IFGRP已关闭。

ifgrp down.png

IFRP显示两个端口均已关闭、例如：

Cluster::> network port ifgrp show
 Port    Distribution              Active
 Node   ifgrp   Function    MAC Address    Ports  Ports
 ------  -------  ------------ --------------   ------- ---------------
 node0   a0a    ip       02:a0:98:11:22:33 none  e0c

LACPDU不递增

注意：此计数器是在 ifconfig -v ONTAP 9.3中添加到的

等待2分钟、然后再次运行它、以验证LACPDU是否增加

已确认物理链路连接。
已尝试从ifgrp中删除端口并重新添加端口、但ifgrp仍显示关闭。
已选择物理端口、但状态仍然相同。
EMS日志中会显示以下链接关闭消息。
