适用场景

  • ONTAP 9.2 , 9.3 和 9.4
  • 链路聚合控制协议( LACP )接口组

问题描述

  • ifgrp show 将多模式 LACP 接口组中的一个或多个端口显示为关闭,表示它们不参与链路聚合
  • 成员端口已物理启动,但 ifgrp show显示为关闭

cluster1::> ifgrp show -node cluster1-01 -ifgrp a0a

Node: cluster1-01
Interface Group Name: a0a
Network Ports: e0c, e0d
Up Ports: e0d,
Down Ports: e0c

  • 此问题描述会在节点重新启动或链路驱动器后随机发生
  • node shell 命令 ifconfig -v 指示关闭的端口具有不同的滞后 ID :

cluster1::> node run -node cluster1-01 ifconfig -v

a0a : flags=8843<up , broadcast , running , sopolyast , multicas> metric 0 mtu 9000 options=6407bb<RXCSUM , TXCSUM , VLAN_mtu , vlan_csu HWM , TSO4 , TSO6 , LRO , VLAN_RXCSUM , RXCSUM_IPv6 , TXUM_IPv6

ether 02:a0:98:XX:YY:ZZ

lag id: [(8000,02-A0-98-11-22-33,0032,0000,0000),
(8000,AA-BB-CC-DD-EE-FF,0037,0000,0000)]

laggport: e0d flags=1c<ACTIVE,COLLECTING,DISTRIBUTING> state=3d<ACTIVITY,AGGREGATION,SYNC,COLLECTING,DISTRIBUTING>
[(8000,02-A0-98-11-22-33,0032,8000,0006),
(8000,AA-BB-CC-DD-EE-FF,0037,8000,00B9)]
input/output LACPDUs: 460 / 14099

laggport: e0c flags=18<COLLECTING,DISTRIBUTING> state=3d<ACTIVITY,AGGREGATION,SYNC,COLLECTING,DISTRIBUTING>
[(8000,02-A0-98-11-22-33,0033,8000,0007)
(8000,AA-BB-CC-DD-EE-FF,0037,8000,043A)]
input/output LACPDUs: 460 / 14099

  • 检查 ifconfig -v 输出中 LACP 端口的 LACPDU 中发送的系统 ID 和密钥值
    • 在上面的示例中,存储节点正在从其每个端口发送 systemID 02-A0-98-11-22-33 ,而交换机正在发送 systemID AA-BB-CC-DD-EE-FF
    • 与 systemID 同一行的是密钥值 0032,该值由交换机中的存储端口 e0d (与滞后 ID 相同)和 0033 (关闭 e0c 端口,因为它不匹配)和 0037 发送
  • 接口组(例如 a0a )配置在非默认 IP 空间中:

cluster1::> network port show -node cluster1-01 -port a0a -fields node,port,ipspace
