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)
