Applies to

  • ONTAP 9.13.1
  • ONTAP 9.13.1P1
  • ONTAP 9.13.1P2
  • interface group (ifgrp)

Issue

  • ifgrp is healthy
    • and at least 1 member port is degraded due to l2_reachability
    • and at least 1 member port is healthy

      Example:

::*> 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

Note: Only member ports (e.g. e0e) are degraded, the ifgrp status and VLANs are healthy

::*> network port ifgrp show
