Native VLAN ports show degraded after upgrade to ONTAP 9.13.1

Last Updated:

Applies to

  • ONTAP 9.13.1 and later
  • VLAN
  • Connectivity Fault Management (CFM)


  • Native/untagged VLAN ports (a0a, e0a, e1c) report degraded due to L2_reachability
  • Ports with VLANs, such as a0a-100 , e0a-20 or e1c-25, do NOT show degraded
  • The Ethernet switch has no port-based (or untagged) VLAN configured on the corresponding link aggregation group (LAG) and member ports but only a VLAN trunk, resulting in untagged frames being discarded on these ports
