Symptom
Configuring Xconnect along with vlan create and vn-segment mapping in a single request message via REST, does not enable xconnect.
Conditions
Configuring Xconnect has dependencies on vlan creation and vn-segment. Vlan creation has to happen first then vn-segment added followed by Xconnect. With CLI, this sequence is enforced naturally. With sandbox/REST request however, the sequence is not enforced and the request comes with all three at the same time causing the problem.
Workaround
User can configure Xconnect in a separate REST message. Vlan create and vn-segment can be configured together in a single request.
