構成を変更すると、NSX Manager は通常、変更の実装を求める要求を別のコンポーネントに送信します。レイヤー 3 エンティティによっては、API を使用して設定を変更した場合に、要求の状態を追跡して、変更が正常に実装されたかどうかを確認できることがあります。

ユーザーが開始した設定の変更は、最適な状態と呼ばれます。変更を実装した結果は、認識された状態と呼ばれます。NSX Manager が変更を正常に実装した場合は、認識された状態が最適な状態と同じになります。エラーがある場合は、認識された状態が最適な状態と同じになりません。

レイヤー 3 エンティティによっては、API を呼び出して設定を変更した場合、応答にパラメータ request_id が含まれることがあります。パラメータ request_id および entity_id を使用して API 呼び出しを行い、要求の状態を特定することができます。

この機能は、次のエンティティおよび API をサポートしています。

次の API を呼び出して、認識された状態を取得できます。
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.
