In the OpenShift Web Console, the Type column for a NetworkAttachmentDefinition (NAD) displays as "Not Available" if the resource was created via a YAML manifest (either through the "Import YAML" button or via oc apply).

Conversely, if the NAD is created using the guided form in the UI, the type displays correctly. 

Despite the UI error, the underlying networking functionality works as expected, and pods can successfully attach to the network, indicating a front-end parsing or display issue.

1. Create a NAD using the CLI. e.g [1]

Then, navigate to the web console -->  Networking -->  NetworkAttachmentDefinitions and verify the Type section for the newly created NAD.


[1]

apiVersion: k8s.cni.cncf.io/v1
kind: NetworkAttachmentDefinition
metadata:
  annotations:
    description: vlan123
  name: vlan123
  namespace: default
spec:
  config: '{"name":"vlan123","cniVersion":"0.3.1","plugins":[{"type":"cnv-bridge","bridge":"br123","ipam":{}},{"type":"cnv-tuning"}]}'

    

    The Type column for the newly created NAD displays as "Not Available".

    The Type column should display the value defined in the type field within the config.
