Updating an EIP

Function

This API is used to bind an EIP to a NIC, or unbind an EIP from a NIC.

Note

Note the following when you use EIPs of the Dedicated Load Balancer (5_gray) type:

In eu-de, EIPs of the Dedicated Load Balancer (5_gray) type cannot be created any more.
Existing EIPs of the Dedicated Load Balancer (5_gray) type can be bound to dedicated or shared load balancers.
- The EIP console cannot be used to bind EIPs to or unbind them from dedicated load balancers.
- You can use APIs to bind EIPs to or unbind them from dedicated load balancers. For details, see "Binding an EIP" and "Unbinding an EIP" in "API V3" section in the Elastic IP API Reference.
- EIPs of this type can be bound to or unbound from shared load balancers using the EIP console or APIs.
Do not add EIPs of the dedicated load balancer type (5_gray) and other types to the same shared bandwidth. Otherwise, the bandwidth limit policy will not take effect.

URI

PUT /v1/{project_id}/publicips/{publicip_id}

Table 1 <vpc_eip_0004__table25231885> describes the parameters.

**Table 1** Parameter description
Name	Mandatory	Description
project_id	Yes	Specifies the project ID.
publicip_id	Yes	Specifies the unique identifier of an EIP.

Request Message

Request parameter

**Table 2** Request header parameter
Parameter	Mandatory	Type	Description
X-Auth-Token	Yes	String	Specifies the user token. The token can be obtained by calling the IAM API used for obtaining a user token. The value of X-Subject-Token in the response header is the user token.

**Table 3** Request parameter
Name	Mandatory	Type	Description
publicip	Yes	`publicip <vpc_eip_0004__table23403840>` object	Specifies the EIP object. For details, see `Table 4 <vpc_eip_0004__table23403840>`.

**Table 4** Description of the **publicip** field
Name	Mandatory	Type	Description
port_id	No	String	Specifies the port ID. The value must be an existing port ID. If this parameter is not included or the parameter value is left blank, the EIP is unbound. If the specified port ID does not exist or has already been bound with an EIP, an error message will be displayed. Leaving this parameter blank does not unbind the EIP from the dedicated load balancer.

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 5** Response parameter
Name	Type	Description
publicip	`publicip <vpc_eip_0004__table83964341880>` object	Specifies the EIP object. For details, see `Table 6 <vpc_eip_0004__table83964341880>`.

**Table 6** 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) NOTIFYING (Assigning) NOTIFY_DELETE (Releasing) DOWN (Unbound) ACTIVE (Bound) ELB (Bound to a load balancer) VPN (Bound to a VPN) ERROR (Exceptions)
profile	`profile <vpc_eip_0004__table66651219193417>` object	Specifies the additional parameters, including the order ID and product ID. For details, see `Table 7 <vpc_eip_0004__table66651219193417>`.
type	String	Specifies the EIP type. The value can be 5_bgp (Dynamic BGP), 5_mailbgp (Mail BGP), or 5_gray (Dedicated load balancer, shared load balancer). 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.
ip_version	Integer	Specifies the IP address version. The value can be 4 or 6. 4: IPv4 6: IPv6 (IPv6 is not supported currently.)
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. Note The value of private_ip_address is null if the EIP is bound to a dedicated load balancer.
port_id	String	Specifies the port ID. This parameter is returned only when a port is associated with the EIP. Note The value of port_id is null if the EIP is bound to a dedicated load balancer.
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.
bandwidth_size	Integer	Specifies the bandwidth (Mbit/s).
bandwidth_share_type	String	Specifies the EIP bandwidth type. The value can be PER or WHOLE. PER: Dedicated bandwidth WHOLE: Shared bandwidth
enterprise_project_id	String	Specifies the enterprise project ID. The value is 0 or a string that contains a maximum of 36 characters in UUID format with hyphens (-). When you assign an EIP, associate an enterprise project ID with the EIP. If this parameter is not specified, the default value is 0, which indicates that the default enterprise project is used. Note This parameter is unsupported. Do not use it.

**Table 7** Description of the **profile** field
Name	Type	Description
order_id	String	Specifies the order ID.
product_id	String	Specifies the product ID.
region_id	String	Specifies the region ID.
user_id	String	Specifies the user ID.
