适用于

  • 集群模式 Data ONTAP 9.2 或更高版本
  • LACP Ifgrp

问题

"ifgrp show " 将多模式 LACP Ifgrp 中的一个或多个端口显示为 down ,这表示它不参与链路聚合。

成员端口物理上处于打开状态,但 "ifgrp show " 显示它已关闭。

Cluster::> ifgrp show -node node01 -ifgrp a0a

Node: node1Interface Group Name: a0a

Network Ports: e0c, e0d

Up Ports: e0d,

Down Ports: e0c

'ifconfig -v ' :

Check SystemID and Key value sent in LACPDUs of LACP Ports. LACPDU counters can also be viewed using command "     ifconfig -v  " from ONTAP 9.2 onwards.

In the example above, filer is sending the systemID as 02-A0-98-XX-YY-ZZ from each of it's ports and the switch is sending systemID as AA-BB-CC-DD-EE-FF.

Next field to the systemID is for Key value. "0032" and "0037" are Key values from the filer and switch, respectively.

检查 ifgrp 端口“ a0a ”是否在非默认 IP 空间中配置。

Cluster::> network port show -node node01 -port a0a -fields IPspace node         port ipspace

cdot-vsim1-01 a0a test <<<< Non-default IP space
