Associates a high-availability virtual IP address (HAVIP) with an Elastic Compute Service (ECS) instance or an elastic network interface (ENI).
Operation description
When you call this operation, take note of the following limits:
-
An HAVIP immediately takes effect after it is associated. You do not need to restart the ECS instance. However, you must associate the HAVIP with the ENI of the ECS instance.
-
The HAVIP and ECS instance must belong to the same vSwitch.
-
You can associate an HAVIP with at most two ECS instances.
-
The ECS instance must be in the Running or Stopped state.
-
The HAVIP must be in the Available or InUse state.
-
The AssociateHaVip operation is asynchronous. After you send the request, the system returns a request ID. However, the operation is still being performed in the system background. You can call the DescribeHaVips operation to query the status of an HAVIP:
- If the HAVIP is in the Associating state, the HAVIP is being associated.
- If the HAVIP is in the InUse state, the HAVIP is associated.
-
You cannot repeatedly call the AssociateHaVip operation to associate an HAVIP within the specified period of time.

Authorization information
The following table shows the authorization information corresponding to the API. The authorization information can be used in the Action policy element to grant a RAM user or RAM role the permissions to call this API operation. Description:
- Operation: the value that you can use in the Action element to specify the operation on a resource.
- Access level: the access level of each operation. The levels are read, write, and list.
- Resource type: the type of the resource on which you can authorize the RAM user or the RAM role to perform the operation. Take note of the following items:
- The required resource types are displayed in bold characters.
- If the permissions cannot be granted at the resource level,
All Resourcesis used in the Resource type column of the operation.
- Condition Key: the condition key that is defined by the cloud service.
- Associated operation: other operations that the RAM user or the RAM role must have permissions to perform to complete the operation. To complete the operation, the RAM user or the RAM role must have the permissions to perform the associated operations.

Request parameters
| Parameter | Type | Required | Description | Example |
|---|---|---|---|---|
| ClientToken | string | No | The client token that is used to ensure the idempotence of the request. You can use the client to generate the value, but you must make sure that it is unique among different requests. The client token can contain only ASCII characters. Note
If you do not set this parameter, the system uses RequestId as ClientToken. The value of RequestId in each API request may be different.
| 0c593ea1-3bea-11e9-b96b-88e9fe63**** |
| RegionId | string | Yes | The ID of the region to which the HAVIP belongs. You can call the DescribeRegions operation to query the most recent region list. | cn-shanghai |
| HaVipId | string | Yes | The ID of the HAVIP. | havip-2zeo05qre24nhrqpy**** |
| InstanceId | string | Yes | The ID of the ECS instance to be associated with the HAVIP. | i-faf344422ffsfad**** |
| InstanceType | string | No | The type of the instance to be associated with the HAVIP. Valid values:
| EcsInstance |
