環境

  • ONTAP 9
  • LACP ifgrps

問題

  • ONTAP は 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ースがアクティブにならず、ダウン状態として表示されます:

::> 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 は次のように報告します:

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 vs 0037)を送信しており、ACTIVE state:の ifgrp にインターフェースが 1 つしか残っていません。

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

  • LACP ifgrp 内のすべてのポートは、ifgrp 内でアクティブになるために、LACP ピアから同じキーを受信する必要があります。
