Request parameters

Parameter	Type	Required	Description	Example
ClientToken	string	No	The client token that is used to ensure the idempotence of the request. You can use the client to generate the token, but you must make sure that the token is unique among different requests. The token can contain only ASCII characters. Note If you do not specify this parameter, the system automatically uses the request ID as the client token. The request ID may be different for each request.	5A2CFF0E-5718-45B5-9D4D-70B3FF3898
DryRun	boolean	No	Specifies whether to perform only a dry run, without performing the actual request. Valid values: true: performs only a dry run. The system checks the request for potential issues, including missing parameter values, incorrect request syntax, and service limits. If the request fails the dry run, an error message is returned. If the request passes the dry run, the `DryRunOperation` error code is returned. false (default): performs a dry run and sends the request. If the request passes the dry run, a `2xx HTTP` status code is returned and the operation is performed.	true
LoadBalancerId	string	Yes	The ID of the ALB instance.	lb-bp1b6c719dfa08ex****
ZoneMappings	array<object>	Yes	The zones and the vSwitches in the zones. You can specify a maximum of 10 zones. If the selected region supports two or more zones, select at least two zones to ensure the high availability of your service. The specified zones and vSwitches overwrite the existing configurations.
	object	Yes	The zones and the vSwitches in the zones. You can specify a maximum of 10 zones. If the selected region supports two or more zones, select at least two zones to ensure the high availability of your service. The specified zones and vSwitches overwrite the existing configurations.
VSwitchId	string	Yes	The ID of the vSwitch in the zone. By default, each zone contains one vSwitch and one subnet. You can specify at most 10 zones. If the region supports two or more zones, specify at least two zones.	vsw-bp1rmcrwg3erh1fh8****
ZoneId	string	Yes	The zone name. You can call the DescribeZones operation to query the most recent zone list. You can specify at most 10 zones. If the region supports two or more zones, specify at least two zones.	cn-hangzhou-a
