Creating a Load Balancer

• Example request 2

  (Bind an EIP to the port that has been bound to the load balancer's private IP address. For details about the parameters, see Table 7.)

  Table 7 Request parameters

  Parameter	Mandatory	Type	Description
  publicip	Yes	Object	Specifies the EIP. For details, see Table 8.
  bandwidth	Yes	Object	Specifies the bandwidth. For details, see Table 9.
  enterprise_project_id	No	String	Specifies the enterprise project ID. The value is 0 or a UUID that can contain a maximum of 36 characters, including hyphens (-). When assigning an EIP, you need to bind an enterprise project ID to the EIP. If this parameter is not specified, the default value is 0. NOTE: For more information about enterprise projects and how to obtain enterprise project IDs, see Enterprise Management User Guide.

  Table 8 publicip parameter description

  Parameter	Mandatory	Type	Description
  type	Yes	String	Specifies the EIP type. The value can be 5_telcom, 5_union, 5_bgp, or 5_sbgp. CN South-Guangzhou: 5_bgp and 5_sbgp CN East-Shanghai2: 5_bgp and 5_sbgp CN North-Beijing1: 5_bgp and 5_sbgp CN-Hong Kong: 5_bgp CN Southwest-Guiyang1: 5_bgp and 5_sbgp CN North-Beijing4: 5_bgp and 5_sbgp Note: 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. 4 indicates an IPv4 address, and 6 indicates an IPv6 address. Note: The configured value must be supported by the system. If this parameter is left blank or is an empty string, an IPv4 address is assigned by default.
  ip_address	No	String	Specifies the EIP to be assigned. The system automatically assigns an EIP if you do not specify it. The value must be a valid IPv4 address in the available IP address range.

  Table 9 bandwidth parameter description

  Parameter	Mandatory	Type	Description
  name	No	String	Specifies the bandwidth name. The value can contain 1 to 64 characters that can contain 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	No	Integer	Specifies the bandwidth (Mbit/s). The value ranges from 1 to 300 by default. (The 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 unit 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 to 300 Mbit/s. The minimum increment is 50 Mbit/s if the allowed bandwidth ranges from 301 Mbit/s to 1000 Mbit/s. The minimum increment is 500 Mbit/s if the allowed bandwidth is greater than 1,000 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. Value options: PER: indicates dedicated bandwidth. WHOLE: indicated shared bandwidth.
  charge_mode	No	String	The default value is traffic. Currently, only billing by traffic is supported.

  • Step 1: Apply for an EIP.
