由于MTU不匹配、SnapMirror操作一直失败、并显示ktls.badAuth

• ONTAP 9
• SnapMirror

• SnapMirror操作因以下CSM错误而失败：
  • CSM: An operation failed due to an ONC RPC failure.
  • CSM: Operation referred to a non-existent session.
  • CSM: Connection aborted.
  • CSM: Request was canceled because of a connection failure.
• SNAPMIRROR-AUDIT-LOG-TXT.GZ ON目标指示重复的CSM错误

status=Failure message=Transfer failed.(Replication operation request failed from Cluster Id: <SOURCE_CLUSTER_ID>, Node Id: <SOURCE_NODE_ID> to Cluster Id: <DESTINATION_CLUSTER_ID>, Node Id: <DESTINATION_NODE_ID> due to a network error(CSM: Request was canceled because of a connection failure.))

• EMS-LOG-FILE.GZ on目标同时指示csm.sessionFailed 和/或ktls.badAuth

[<NODE>: CSM_BTLS: ktls.badAuth:notice]: ONTAP received a TLS message with incorrect authentication at local address <DESTINATION_INTERCLUSTER_LIF> local port 24278 from remote address <SOURCE_INTERCLUSTER_LIF> remote port 11105 via IPspace -1.
