ACI Node state - undiscovered Vs Unknown

 

  Undiscovered:

  • You’ve manually added a node ID in APIC.
  • The switch is not yet connected or powered on.
  • Could be due to cabling issues or incorrect port configuration.

  Unknown:

  • The switch is physically connected and sending LLDP packets.
  • APIC detects it but doesn’t have a matching Node ID policy.
  • You need to assign a Node ID to complete discovery.
