Function

This API is used to assign an EIP.

The EIP service provides independent public IP addresses and bandwidth for Internet access. EIPs can be bound to or unbound from ECSs, BMSs, virtual IP addresses, NAT gateways, or load balancers.

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

In eu-de, no more new EIPs of this type can be assigned. You can assign EIPs of the BGP (5_bgp) type.
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.
- EIPs of this type can be bound to or unbound from shared load balancers using the EIP console or APIs.
- You are advised to bind or unbind BGP EIPs to or from dedicated load balancers.
5_gray EIPs cannot be added to the same shared bandwidth as EIPs of other types. If they are in the same shared bandwidth, the bandwidth limit settings will not take effect.

Table 1 describes the parameters.

**Table 1** Parameter description
Parameter	Mandatory	Description
project_id	Yes	Specifies the project ID.

Request Parameters

**Table 2** Request body parameter
Parameter	Mandatory	Type	Description
publicip	Yes	publicip object	Specifies the EIP object. For details, see Table 3.
bandwidth	Yes	bandwidth object	Specifies the bandwidth object. For details, see Table 4.

**Table 3** Description of the **publicip** field
Parameter	Mandatory	Type	Description
type	Yes	String	Specifies the EIP type. The value can be 5_bgp (Dynamic BGP), 5_mailbgp (Mail BGP), 5_gray (Dedicated Load Balancer), or 5_dualStack. 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.
ip_version	No	Integer	Specifies the EIP version. The value can be 4 and 6, indicating IPv4 address and IPv6 address, respectively. IPv6 is not supported currently. Constraints: The configured value must be supported by the system. If this parameter is left blank or is an empty string, IPv4 address is created by default.
alias	No	String	Specifies the EIP name. The value can contain 1 to 64 characters, including letters, digits, underscores (_), hyphens (-), and periods (.).

**Table 4** Description of the **bandwidth** field
Parameter	Mandatory	Type	Description
name	Yes	String	Specifies the bandwidth name. The value can contain 1 to 64 characters, including letters, digits, underscores (_), hyphens (-), and periods (.). This parameter is mandatory when share_type is set to PER. This parameter will be ignored when share_type is set to WHOLE with an ID specified.
size	Yes	Integer	Specifies the bandwidth size. The value ranges from 1 Mbit/s to 1000 Mbit/s by default. (The specific range may vary depending on the configuration in each region. You can see the bandwidth range of each region on the management console.) This parameter is mandatory when share_type is set to PER. This parameter will be ignored when share_type is set to WHOLE with an ID specified. The minimum increment for bandwidth adjustment varies depending on the bandwidth range. The details are as follows: The minimum increment is 1 Mbit/s if the allowed bandwidth ranges from 0 Mbit/s to 300 Mbit/s (with 300 Mbit/s included). The minimum increment is 50 Mbit/s if the allowed bandwidth ranges from 300 Mbit/s to 1000 Mbit/s (with 1000 Mbit/s included). The minimum increment is 500 Mbit/s if the allowed bandwidth is greater than 1000 Mbit/s.
id	No	String	Specifies the bandwidth ID. You can specify an existing shared bandwidth when assigning an EIP. The value can be the ID of the shared bandwidth whose type is set to WHOLE.
share_type	Yes	String	Specifies the bandwidth type. Possible values are as follows: PER: Dedicated bandwidth WHOLE: Shared bandwidth If this parameter is set to WHOLE, the bandwidth ID must be specified.
charge_mode	No	String	Specifies whether the bandwidth is billed by traffic or by bandwidth size. The value is traffic, indicating that the billing is based on traffic.

Response Message

Response parameter

**Table 5** Response parameter
Parameter	Type	Description
publicip	publicip object	Specifies the EIP object. For details, see Table 6.

**Table 6** Description of the **publicip** field
Parameter	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 (Release) DOWN (Unbound) ACTIVE (Bound) ELB (Bound to a load balancer) VPN (Bound to a VPN) ERROR (Exceptions)
type	String	Specifies the EIP type. The value can be 5_bgp (Dynamic BGP), 5_mailbgp (Mail BGP), 5_gray (Dedicated Load Balancer), or 5_dualStack. 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.)
tenant_id	String	Specifies the project ID.
create_time	String	Specifies the time (UTC) when the EIP is assigned. Format: yyyy-MM-dd HH:mm:ss
bandwidth_size	Integer	Specifies the bandwidth (Mbit/s).
alias	String	Specifies the EIP name.
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.
public_border_group	String	Specifies whether it is in a central site or an edge site. The value can be: center Edge site name This resource can only be associated with an EIP of the same region.
