The tmnxSubMngdHostCreationFail notification is sent when an attempt to create a managed host has failed. The value of sapPortId and sapEncapValue may refer to a managed SAP that does not exist (anymore) at the moment this notification is evaluated. [CAUSE] A failure occurs while trying to create a managed host. The object tmnxSubAdditionalInfo provides more information about the failure. [EFFECT] The context for the managed host is not created. The system cannot provide network connectivity to the host. [RECOVERY] The recovery action depends on the root cause of the failure. The root cause may be a misconfiguration in the client device, the access network, in this system, or in the AAA server configuration.
