LACP 端口由于对等键不匹配而关闭
适用于
- ONTAP 9
- LACP ifgrps
问题
- ONTAP 已从 LACP 对等端接收到不同的密钥，导致一个或多个接口在 ifgrp 中处于非活动状态，并显示为 down：
::> network port ifgrp show -instance
Node: node1
Interface Group Name: a0a
Distribution Function: port
Create Policy: multimode_lacp
MAC Address: d2:39:ea:xx:xx:xx
Port Participation: partial
Network Ports: e0c, e0e
Up Ports: e0e
Down Ports: e0c
- EMS报告如下：
Fri Dec 13 21:49:10 +0000 [NODE-01: intr: net.ifgrp.lacp.key.mismatch:error]: Partner mismatch occured on ifgrp "a0a", port "e3b". Expected by aggregate: system-priority "0x9b7f", system-ID "XX:XX:XX:XX:XX:XX", and key "0x0037". Found at Port: system-priority "0x9b7f", system-ID "XX:XX:XX:XX:XX:XX", and key "0x0036".
- LACP 对等体正在发送两个不同的
keys（0036 与 0037），这导致 ifgrp 中只剩下一个接口处于ACTIVE state:
::> system node run -node node1 -command ifconfig -v

- LACP ifgrp 中的所有端口必须从 LACP 对等端接收相同的密钥，才能在 ifgrp 中处于 ACTIVE 状态。
