Checking the Realized State of a Configuration Change

When you make a configuration change, NSX Manager typically sends a request to another component to implement the change. For some layer 3 entities, if you make the configuration change using the API, you can track the status of the request to see if the change is successfully implemented.

The configuration change that you initiate is called the desired state. The result of implementing the change is called the realized state. If NSX Manager implements the change successfully, the realized state will be the same as the desired state. If there is an error, the realized state will not be the same as the desired state.

For some layer 3 entities, when you call an API to make a configuration change, the response will include the parameter request_id. You can use the parameters request_id and the entity_id to make an API call to find out the status of the request.

You can call the following APIs to get the realized states:

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.
