Associates a high-availability virtual IP address (HAVIP) with an Edge Node Service (ENS) instance or elastic network interface (ENI).
Operation description
When you call this operation to associate an HAVIP, take note of the following items:
-
An HAVIP immediately takes effect after it is associated. You do not need to restart the ENS instance. However, you need to associate the HAVIP with the ENI of the ENS instance.
-
The HAVIP and ENS instance must belong to the same vSwitch.
-
The ENS instance must be in the Running or Stopped state.
-
The HAVIP must be in the Available or InUse state.
-
AssociateHaVip is an asynchronous operation. After a request is sent, the system returns a request ID and runs the task in the 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.
