Example request 1 (Binding an EIP to a NIC)

PUT https://{Endpoint}/v1/{project_id}/publicips/{publicip_id}

{
    "publicip": {
        "port_id": "f588ccfa-8750-4d7c-bf5d-2ede24414706"
    }

Response Message

Response parameter

**Table 4** Response parameter
Name	Type	Description
publicip	Object	Specifies the EIP object. For details, see Table 5.

**Table 5** Description of the **publicips** field
Name	Type	Description
id	String	Specifies the unique identifier of an EIP.
status	String	Specifies the EIP status. Possible values are as follows: FREEZED (Frozen) BIND_ERROR (Binding failed) BINDING (Binding) PENDING_DELETE (Releasing) PENDING_CREATE (Assigning) PENDING_UPDATE (Updating) DOWN (Unbound) ACTIVE (Bound) ELB (Bound to a load balancer) ERROR (Exceptions)
type	String	Specifies the EIP type. The value can be 5_bgp. Constraints: The configured value must be supported by the system. publicip_id is an IPv4 port. If publicip_type is not specified, the default value is 5_bgp.
public_ip_address	String	Specifies the obtained EIP if only IPv4 EIPs are available.
private_ip_address	String	Specifies the private IP address bound to the EIP. This parameter is returned only when a port is associated with the EIP.

tenant_id	String	Specifies the project ID.
create_time	String	Specifies the time (UTC) when the EIP is assigned.
bandwidth_id	String	Specifies the ID of the EIP bandwidth.
