ModifyInstanceVpcAttribute

Description

When you call this operation, note that:

• You can only modify the VPC attributes of an ECS instance which is in the stopped (Stopped) state.
• A new ECS instance must have been started and stopped before you call this operation.
• An ECS instance that has the VPC attributes modified must have been started and stopped before you call this operation.
• If VSwitchId is specified when you call this operation,VSwitchId must belong to the current VPC.
• If VSwitchId is specified when you call this operation but PrivateIpAddress is not specified, the system automatically allocates a private IP address to the ECS instance.
• The current VSwitch and the new VSwitch (VSwitchId) must belong to a zone in the same region.
• The current VSwitch and the new VSwitch (VSwitchId) must belong to the same VPC.
• If both VSwitchId and PrivateIpAddress are specified, the private IP address must belong to the CIDR block of the specified VSwitch. PrivateIpAddress depends on VSwitchId, so you cannot specify only PrivateIpAddress.

Debugging
