Unless otherwise specified, exact match is applied.

URI

GET /v2/{project_id}/elb/loadbalancers

**Table 1** Path parameters
Parameter	Mandatory	Type	Description
project_id	Yes	String	Specifies the project ID.

**Table 2** Query parameters
Parameter	Mandatory	Type	Description
marker	No	String	Specifies the ID of the listener from which pagination query starts, that is, the ID of the last listener on the previous page. This parameter must be used together with limit.
limit	No	Integer	Specifies the number of listeners on each page. If this parameter is not set, all load balancers are queried by default.
page_reverse	No	Boolean	Specifies the page direction. The value can be true or false, and the default value is false. The last page in the list requested with page_reverse set to false will not contain the "next" link, and the last page in the list requested with page_reverse set to true will not contain the "previous" link. This parameter must be used together with limit.
id	No	String	Specifies the load balancer ID.
description	No	String	Provides supplementary information about the load balancer. The value contains a maximum of 255 characters.
name	No	String	Specifies the load balancer name. The value contains a maximum of 255 characters.
operating_status	No	String	This parameter is reserved, and its value can be ONLINE or FROZEN. It specifies the operating status of the load balancer.
provisioning_status	No	String	This parameter is reserved, and its value can only be ACTIVE. It specifies the provisioning status of the load balancer.
admin_state_up	No	Boolean	Specifies the administrative status of the load balancer. This parameter is reserved, and the default value is true.
vip_address	No	String	Specifies the private IP address of the load balancer. The value contains a maximum of 64 characters.
vip_port_id	No	String	Specifies the ID of the port bound to the private IP address of the load balancer.
vip_subnet_id	No	String	Specifies the ID of the subnet where the load balancer resides.
member_address	No	String	Specifies the IP address of the backend server associated with the load balancer.
member_device_id	No	String	Specifies the ID of the cloud server used as the backend server associated with the load balancer.
vpc_id	No	String	Specifies the ID of the VPC where the load balancer resides.
enterprise_project_id	No	String	Specifies the enterprise project ID. If enterprise_project_id is not passed, resources in all enterprise projects are queried by default. Fine-grained authorization is performed. The elb:loadbalancers:list permissions must be assigned to the user group. If enterprise_project_id is passed, the value can be a specific enterprise project ID or all_granted_eps. If the value is a specific enterprise project ID, only resources in the enterprise project are queried. If the value is all_granted_eps, resources in the enterprise projects with the elb:loadbalancers:list permissions are queried.
