Function

This API is used to query details about a load balancer using its ID. You can also query the EIP bound to the load balancer based on the value of vip_port_id.

URI

GET /v2.0/lbaas/loadbalancers/{loadbalancer_id}

**Table 1** Parameter description
Parameter	Mandatory	Type	Description
loadbalancer_id	Yes	String	Specifies the load balancer ID.

Request

None
