Un nodo de transporte de host ESXi es compatible con ocho plantillas de flujo IPFIX de conmutadores lógicos.

El siguiente diagrama muestra el flujo de tráfico entre las máquinas virtuales conectadas a los hosts ESXi supervisados por la función IPFIX:

La plantilla encapsulada de IPv4 incluye los siguientes elementos:
  • elementos estándar
  • SrcAddr: VTEP1
  • DstAddr: VTEP2
  • tenantSourceIPv4: IP1
  • tenantDestIPv4: IP2
  • tenantSourcePort: 10000
  • tenantDestPort: 80
  • tenantProtocol: TCP
  • ingressInterfaceAttr: 0x03 (puerto de túnel)
  • egressInterfaceAttr: 0x01
  • encapExportRole: 01
  • virtualObsID: 89fd5032-2dc9-4fc3-993a-9bb4b616de54 (identificador de puerto lógico)
