    1. API Description

    Domain name for API request: clb.tencentcloudapi.com.

    This API is used to create a clone of the source CLB instance with the same forwarding rules and binding relations. Note that this API is asynchronous, which means that changes to the source CLB after invocation of the API are not included in the clone.

    Limits:
    Instance attribute restrictions
    Only pay-as-you-go instances can be cloned. Monthly-subscribed instances cannot be cloned.
    CLB instances without any billable items cannot be cloned.
    Classic CLB instances and CLB u200dinstances created for Anti-DDoS service cannot be cloned.
    Classic network-based instances cannot be cloned.
    IPv6 instances, IPv6 NAT64 instances, and instances bound with both IPv4 and IPv6 cannot be cloned.
    The following settings will not be cloned: Custom configuration, Redirection configurations, and Allow Traffic by Default in security groups.
    Before cloning an instance, make sure all certificates used on the instance are valid. Cloning will fail if there are any expired certificates.
    Listener restrictions
    Instances with QUIC listeners or port range listeners cannot be cloned.
    Private network CLB instances with TCP_SSL listeners cannot be cloned.
    Instances with layer-7 listeners that have no forwarding rules cannot be cloned.
    u200dInstances u200dwith more than 50 listeners cannot be cloned.
    Backend service restrictions
    Instances with target groups and SCF cloud functions as the backend services cannot be cloned.

    Notes:
    If you are using a BGP bandwidth package, you need to pass the package ID.
    To create a dedicated cluster-based CLB by cloning the source CLB, you need to pass the cluster ID. Otherwise, a normal CLB is created.
    This API is only available for beta users. To try it out, submit a ticket.

    A maximum of 20 requests can be initiated per second for this API.

    We recommend you to use API Explorer
    Try it
    API Explorer provides a range of capabilities, including online call, signature authentication, SDK code generation, and API quick search. It enables you to view the request, response, and auto-generated examples.

    2. Input Parameters

    The following request parameter list only provides API request parameters and some common parameters. For the complete common parameter list, see Common Request Parameters.

    Parameter Name Required Type Description
    Action Yes String Common Params. The value used for this API: CloneLoadBalancer.
    Version Yes String Common Params. The value used for this API: 2018-03-17.
    Region No String Common Params. This parameter is not required for this API.
    LoadBalancerId Yes String CLB instance ID
    LoadBalancerName No String Clones the name of the CLB instance. The name must be 1-60 characters containing letters, numbers, "-" or "_".
    Note: if the name of a new CLB instance already exists, a default name will be generated automatically.
    ProjectId No Integer ID of the project to which a CLB instance belongs, which can be obtained through the DescribeProject API. If this parameter is not passed in, the default project will be used.
    MasterZoneId No String Sets the primary AZ ID for cross-AZ disaster recovery, such as 100001 or ap-guangzhou-1, which is applicable only to public network CLB.
    Note: A primary AZ loads traffic, while a secondary AZ does not load traffic by default and will be used only if the primary AZ becomes unavailable. The platform will automatically select the optimal secondary AZ. You can use the DescribeResource API to query the primary AZ list of a region.
    SlaveZoneId No String Specifies the secondary AZ ID for cross-AZ disaster recovery, such as 100001 or ap-guangzhou-1. It is applicable only to public network CLB.
    Note: A secondary AZ will load traffic if the primary AZ is faulty. You can use the DescribeMasterZones API to query the primary and secondary AZ list of a region.
    ZoneId No String Specifies an AZ ID for creating a CLB instance, such as ap-guangzhou-1, which is applicable only to public network CLB instances.
    InternetAccessible No InternetAccessible CLB network billing mode. This parameter is applicable only to public network CLB instances.
    VipIsp No String ISP of VIP. Values: CMCC (China Mobile), CUCC (China Unicom) and CTCC (China Telecom). You need to activate static single-line IPs. This feature is in beta and is only available in Guangzhou, Shanghai, Nanjing, Jinan, Hangzhou, Fuzhou, Beijing, Shijiazhuang, Wuhan, Changsha, Chengdu and Chongqing regions. To try it out, please contact your sales rep. If it's specified, the network billing mode must be BANDWIDTH_PACKAGE. If it's not specified, BGP is used by default. To query ISPs supported in a region, please use DescribeResources.
    Vip No String Applies for CLB instances for a specified VIP
    Tags.N No Array of TagInfo Tags a CLB instance when purchasing it
    ExclusiveCluster No ExclusiveCluster Dedicated cluster information
    BandwidthPackageId No String Bandwidth package ID. If this parameter is specified, the network billing mode (InternetAccessible.InternetChargeType) will only support bill-by-bandwidth package (BANDWIDTH_PACKAGE).
    SnatPro No Boolean Whether to support binding cross-VPC IPs or cross-region IPs
    SnatIps.N No Array of SnatIp Creates SnatIp when the binding IPs of other VPCs feature is enabled
    ClusterIds.N No Array of String ID of the public network CLB dedicated cluster
    SlaType No String Specification of the LCU-supported instance.
    ClusterTag No String Tag of the STGW dedicated cluster
    Zones.N No Array of String Availability zones for nearby access of private network CLB instances to distribute traffic
    EipAddressId No String Unique ID of an EIP, which can only be used when binding the EIP of a private network CLB instance (e.g., eip-11112222)

    3. Output Parameters
