升级到ONTAP 9.131后、ifgrp成员端口显示已降级、而ifgrp显示可访问

• ONTAP 9.13.1.
• ONTAP 9.13.1P1
• ONTAP 9.13.1P2
• 接口组(ifgrp)

• ifgrp  运行状况良好
  •  由于L2_re可 访问性、至少有1个成员端口已降级
  • 至少 有1个成员端口 运行状况良好
    
    示例：

::*> network port show
Node: node1
Port      IPspace      Broadcast Domain Link MTU  Admin/Oper  Status
--------- ------------ ---------------- ---- ---- ----------- --------
a0a       Default      Data             up   1500     -/-    healthy
a0a-100   Default      Data             up   1500     -/-    healthy
e0e       Default      -                up   1500  auto/10000 degraded
e0f       Default      -                up   1500  auto/10000 healthy

注意： 只有成员端口(例如e0e)处于降级状态、ifgrp状态和VLAN 运行状况良好

::*> network port ifgrp show
        Port     Distribution                Active
