由于对等系统 ID 不匹配，LACP 端口处于部分状态下线
适用于
- ONTAP 9
- 链路聚合控制协议 (LACP)
- 接口组 (ifgrps) 又称 链路聚合组 (LAG)
问题描述
- 一个或多个接口在带有 LACP 的 ifgrp 中未处于活动状态或显示为关闭：
cluster::> ifgrp show
node ifgrp ports down-ports
-------- ---------- ----- ----------
node1 a0a e0a,e0b,e0c,e0d e0c,e0d
- 物理端口状态已启动：
cluster::> net port show -node node1 -port e0c,e0d
Node: node1
Ignore
Speed(Mbps) Health Health
Port IPspace Broadcast Domain Link MTU Admin/Oper Status Status
--------- ------------ ---------------- ---- ---- ----------- -------- ------
e0c Default Default up 1500 auto/1000 healthy false
e0d Default Default up 1500 auto/1000 healthy false
2 entries were displayed.
- ifconfig -v 表示同一 ifgrp 中不同端口上的多个系统 ID
示例：
- LACP 对等体正在发送两个不同的
system IDs（AA-BB-CC-DD-EE-FF vs FF-EE-DD-CC-BB-AA）。 - 在
active状态下，ifgrp 中只保留一个接口。
