Un nodo di trasporto host ESXi supporta otto modelli di flusso IPFIX di commutatore logico.
Il diagramma seguente illustra il flusso del traffico tra le macchine virtuali collegate agli host ESXi monitorato dalla funzionalità IPFIX:
Il modello IPv4 incapsulato avrà i seguenti elementi:
- elementi standard
- SrcAddr: VTEP1
- DstAddr: VTEP2
- tenantSourceIPv4: IP1
- tenantDestIPv4: IP2
- tenantSourcePort: 10000
- tenantDestPort: 80
- tenantProtocol: TCP
- ingressInterfaceAttr: 0x03 (tunnel port)
- egressInterfaceAttr: 0x01
- encapExportRole: 01
- virtualObsID: 89fd5032-2dc9-4fc3-993a-9bb4b616de54 (ID porta logica)
