Description

Query the detailed information of an SLB instance according to instance ID.

Request parameter

Name	Type	Required	Description
Action	String	Yes	The action to perform. Valid value: `DescribeLoadBalancerAttribute`
RegionId	String	Yes	The ID of the region where the Server Load Balancer instance is located. For example: `cn-hangzhou` Call the DescribeRegions API to get the list of available regions.
MasterZoneId	String	No	The ID of the active zone. By default, the SLB cluster in the active zone is used to distribute traffic. Call the DescribeZone API to get the available zones to use.
SlaveZoneId	String	No	The ID of the standby zone. The standby zone takes over the traffic distribution only when the SLB cluster in the master zone fails. Call the DescribeZone API to get the available zones to use.

Response parameter

Name	Type	Description
RequestId	String	The ID of the request.
LoadBalancerId	String	The ID of SLB instance.
RegionId	String	The ID of the region where the SLB instance is located.
RegionIdAlias	String	The name of the region where the SLB instance is located.
LoadBalancerName	String	The name of the SLB instance.
LoadBalancerStatus	String	The status of the SLB instance. `active` When the SLB instance in the active status, the listeners in the instance can distribute traffic. `inactive` When the SLB instance in the inactive status, the listeners in the instance cannot distribute traffic any more.

AddressType	String	The type of the SLB instance address. Valid values: `internet` \| `intranet`
NetworkType	String	The network type of the SLB instance. Valid values: `classic` \| `vpc`
VpcId	String	The ID of the VPC where the SLB instance is created. Note: This parameter is returned only when a VPC network SLB instance is created.
VswitchId	String	The ID of the VSwitch where the SLB instance is created. Note: This parameter is returned only when a VPC network SLB instance is created.
CreateTime	String	The time at which the SLB instance is created.
ListenerPorts	List	The list of front-end ports configured in the SLB instance. ListenerPort: The used front-end port.
ListenerPortsAndProtocol	List	The list of the front-end ports and protocols configured in the SLB instance. ListenerPort: The used front-end port. ListenerProtocol: The used front-end protocol.
BackendServers	List	The list of the backend servers added to the SLB instance. ServerId: The ID of the backend server (ECS instance). Weight: The weight of the backend server.
