Description

Modifies the attributes of a Virtual Private Cloud (VPC). When you call this interface, consider the following:

• For more information about the APIs for VPC, see API Reference of VPC.
• The ECS instance must be in the Stopped status before the VSwitch can be changed.
• A new instance must have been started and stopped before you call this interface.
• The VPC attributes of an instance that have been modified once must have been started and stopped before you call this interface again.
• When VPC attributes are modified for a specified VSwitchId, the VSwitchId must belong to the same VPC.
• The current VSwitch and new VSwitch of the specified instance must belong to the same zone.
• When VSwitchId is specified and PrivateIpAddress is not specified, the system automatically allocates a private IP address for your ECS instance.
• When both VSwitchId and PrivateIpAddress are specified, the specified PrivateIpAddress must be in the network segment of the specified VSwitch. You must specify the VSwitchId when you modify the PrivateIpAddress of your instance.
