由于对等密钥不匹配、LACP端口关闭

适用场景

• ONTAP 9
• LACP ifgrp

问题描述

• ONTAP 从LACP对等方收到不同的密钥、从而 导致ifgrp中的一个或多个接口未处于活动状态并显示为关闭：

::> 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报告以下信息：

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对等方正在发送两个不同的keys  (0036与0037)、这仅在中的ifgrp中保留一个接口 ACTIVE state:

::> system node run -node node1 -command ifconfig -v

• LACP ifgrp中的所有端口都必须从LACP对等方收到相同的密钥、才能在ifgrp中处于活动状态。
