节点重新启动后， LACP 端口将关闭，交换机端口将处于 "Link lap error-disable" 状态

适用场景

• ONTAP
• 使用链路聚合控制协议(LACP)的接口组

问题描述

• 存储节点在ONTAP升级期间重新启动、并且某些LACP成员处于关闭状态。

::> ifgrp show -fields down-ports,up-ports

• 节点的网络端口已关闭且处于无链路状态。

::> network port show -node <node_name>

• ​​​​​​从存储端没有迹象表明从Active IQ IFCONFIG-VVV 部分或 node run -node <node> ifconfig -v以下位置测量到任何链路轻拍或任何协商LACP的尝试：

a0a: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> metric 0 mtu 9000
lagg statistics:
active ports: 0
flapping: 0
laggport: e0a flags=20000<DEFAULT> state=41<ACTIVITY,DEFAULTED>
     input/output LACPDUs: 0 / 0
laggport: e2c flags=20000<DEFAULT> state=41<ACTIVITY,DEFAULTED>
     input/output LACPDUs: 0 / 0
status: no carrier

• 调查Cisco网络交换机、确定相应的交换机接口处于 Link Flap error-disable 状态。
• Cisco交换机 日志记录显示重复的链路故障并禁用：

%ETHPORT-2-IF_DOWN_LINK_FAILURE: Interface Ethernet1/1/2 is down (Link failure)
%ETHPORT-2-IF_DOWN_LINK_FAILURE: Interface Ethernet1/1/2 is down (Link failure)
%ETH_PORT_CHANNEL-8-PORT_SUSPENDED: Ethernet1/1/2: Ethernet1/1/2 is suspended.
%ETHPORT-2-IF_DOWN_LINK_FAILURE: Interface Ethernet1/1/2 is down (Link failure)
%ETHPORT-2-IF_DOWN_LINK_FAILURE: Interface Ethernet1/1/2 is down (Link failure)
%ETHPORT-2-IF_DOWN_ERROR_DISABLED: Interface Ethernet1/1/2 is down (Error disabled. Reason:Too many link flaps)
