Puede usar las API de NSX-T Data Center para configurar la red y el ancho de banda de las aplicaciones que se ejecutan en el host.
Procedimiento
- Realice una consulta en el host para que muestre los dos perfiles de conmutador de host, tanto el definido por el sistema como el definido por el usuario.
- GET https://<nsx-mgr>/api/v1/host-switch-profiles?include_system_owned=true.
La respuesta de ejemplo muestra el perfil de NIOC aplicado al host.
