Quando si apporta una modifica alla configurazione, NSX Manager invia in genere una richiesta a un altro componente per implementare la modifica. Per alcune entità di livello 3, se la modifica della configurazione viene apportata utilizzando l'API, è possibile monitorare lo stato della richiesta per verificare se la modifica è stata implementata correttamente.

La modifica della configurazione avviata viene denominata stato desiderato. Il risultato dell'implementazione della modifica viene denominato stato realizzato. Se la modifica viene implementata correttamente in NSX Manager, lo stato realizzato sarà uguale allo stato desiderato. Se si verifica un errore, lo stato realizzato non sarà uguale allo stato desiderato.

Per alcune entità di livello 3, quando si chiama un'API per apportare una modifica della configurazione, la risposta includerà il parametro request_id. È possibile utilizzare i parametri request_id e entity_id per effettuare una chiamata API per individuare lo stato della richiesta.

Questa funzionalità supporta le entità e le API seguenti:

Per ottenere gli stati realizzati, è possibile chiamare le API seguenti:
EdgeCluster
Request - GET /edge-clusters/<edge-cluster-id>/state?request_id=<request-id>
Response - An instance of EdgeClusterStateDto which will inherit ConfigurationState. If the edge cluster is deleted then the state will be unknown and it will return the common entity not found error.

LogicalRouter / All L3 Entites - All L3 entities can use this API to get realization state
Request - GET /logical-routers/<logical-router-id>/state?request_id=<request-id>
Response - An instance of LogicalRouterStateDto which will inherit ConfigurationState. Delete operation of any entity other than logical router can be covered by getting the state of logical router but if the logical router itself is deleted then the state will be unknown and it will return the common entity not found error.

LogicalServiceRouterCluster - All L3 entities which are the part of services can use this API to get the realization state
Request - GET /logical-routers/<logical-router-id>/service-cluster/state?request_id=<request-id>
Response - An instance of LogicalServiceRouterClusterState which will inherit ConfigurationState. 

LogicalRouterPort / DhcpRelayService / DhcpRelayProfile
Request - GET /logical-router-ports/<logical-router-port-id>/state?request_id=<request-id>
Response - An instance of LogicalRouterPortStateDto which will inherit ConfigurationState. 

IPSecVPNIKEProfile / IPSecVPNDPDProfile / IPSecVPNTunnelProfile / IPSecVPNLocalEndpoint / IPSecVPNPeerEndpoint / IPSecVPNService / IPSecVPNSession
Request - GET /vpn/ipsec/sessions/<session-id>/state?request_id=<request-id>
Response - An instance of IPSecVPNSessionStateDto which will inherit ConfigurationState. If the session is deleted then the state will be unknown and it will return the common entity not found error. When IPSecVPNService is disabled, IKE itself is down and it does not respond. It will return unknown state in such a case.

DhcpServer
Request - GET /dhcp/servers/<server-id>/state?request_id=<request-id>
Response - An instance of ConfigurationState.

DhcpStaticBinding
Request - GET /dhcp/servers/<server-id>/static-bindings/<binding-id>/state?request_id=<request-id>
Response - An instance of ConfigurationState.

DhcpIpPool
Request - GET /dhcp/servers/<server-id>/ip-pools/<pool-id>/state?request_id=<request-id>
Response - An instance of ConfigurationState.

DnsForwarder
Request - GET /dns/forwarders/<forwarder-id>/state?request_id=<request-id>
Response - An instance of ConfigurationState.
