Weight	Integer	No	Forwarding weight of a real server. Value range: [0, 100]. Default value: 10.
EniIp	String	No	This parameter must be passed in when you bind an ENI, which represents the IP address of the ENI. The ENI has to be bound to a CVM instance first before it can be bound to a CLB instance. Note: Either InstanceId or EniIp must be passed in. To bind an ENI, you need to submit a ticket for application first. Note: This field may return null, indicating that no valid values can be obtained.
