環境

  • ONTAP 9
  • LACP ifgrp

問題

  • ONTAPが LACPピアから異なるキーを受信した ため、ifgrpで1つ以上のインターフェイスがアクティブでなく、downと表示されています。

::> 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で次の情報が報告されます。

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ピアが2つの異なるkeys  (0036対0037)を送信しており、のifgrpには1つのインターフェイスしか残っていません ACTIVE state:

  • LACP ifgrpのすべてのポートがifgrpでアクティブになるには、LACPピアから同じキーを受け取る必要があります。
