Application Scenarios of the VPC Service


You need a port for managing the NIC life cycle when creating an ECS or adding a NIC to the ECS.


Pay attention to the following constraints when invoking native OpenStack APIs due to system service capability limitations:

  • Do not use unsupported parameters when invoking APIs.
  • NICs may be unavailable if APIs are not invoked in accordance with this development guide. In this case, delete the NICs and perform operations according to this document again.
  • You cannot create, modify, or delete the ports of the internal network. All the ports for which you are performing operations must be created by yourself. If you perform operations for the port of the internal network, services may become unavailable.
