操作步骤

1. 创建虚拟IP。
   1. 发送“POST https://VPC的Endpoint/v2.0/ports”。
   2. 在Request Header中增加“X-Auth-Token”。
   3. 在Request Body中传入参数如下，其中vip所在子网需与E CS 同子网。

      {"port": {"network_id": "4779ab1c-7c1a-44b1-a02e-93dfc361b32d","device_owner": "neutron:VIP_PORT","name": "vip_port_test"}}

      或者如下，可以指定IP创建：

      {"port": {"network_id": "4779ab1c-7c1a-44b1-a02e-93dfc361b32d","device_owner": "neutron:VIP_PORT","name": "vip_port_test","fixed_ips": [{"ip_address": "192.168.0.220"}]}}

      • 请求异常时，错误码请参见错误码。
3. 将云服务器与虚拟IP绑定。
   1. 发送“PUT https://VPC的Endpoint/v2.0/ports/{port_id}”。port_id为上面创建的虚拟IP对应的port_id。
   2. 在Request Header中增加“X-Auth-Token”。
   3. 在Request Body中传入参数如下，ip_address为2查询出的云服务器的网卡ip。
