Querying the List of Central Network Attachments

Function

This API is used to query the list of central network attachments.

Parameters marker and limit are used for pagination query. The default value of limit is 0. If marker is not specified, the first data record is returned.

Calling Method

For details, see Calling APIs.

URI

GET /v3/{domain_id}/gcn/central-network/{central_network_id}/attachments

**Table 1** Path Parameters
Parameter	Mandatory	Type	Description
domain_id	Yes	String	Account ID.
central_network_id	Yes	String	Central network ID.

**Table 2** Query Parameters
Parameter	Mandatory	Type	Description
limit	No	Integer	Number of records on each page. Value range: 1 to 1000
marker	No	String	Pagination query information. You can obtain the marker values from the response of the last API call. You can enter the marker value of the previous page or the next page. If you enter the marker value of the previous page, the previous page will be queried. If you enter the marker value of the next page, the next page will be queried. During pagination query, the query criteria, including the filters, sorting criteria, and the limit value, cannot be modified.
sort_key	No	String	Field for sorting.
sort_dir	No	Object	Whether the resources are sorted in ascending or descending order. asc indicates the ascending order and desc indicates the descending order.
id	No	Array of arrays	Resource ID. Multiple IDs can be queried.
name	No	Array of strings	Resource name. Multiple names can be queried.
attachment_instance_type	No	Array of arrays	Attachment type. Multiple attachment types can be queried.
state	No	Array of arrays	Central network connection status. Multiple statuses can be queried.
attachment_instance_id	No	Array of arrays	Attachment ID.

Request Parameters

**Table 3** Request header parameters
Parameter	Mandatory	Type	Description

attachment_instance_id	String	ID of the resource used as an attachment on the central network, for example, enterprise router route table ID or global DC gateway ID.
attachment_id	String	Attachment ID of the enterprise router or peer link ID of the global DC gateway.
attachment_instance_project_id	String	Project ID of the resource used as an attachment on the central network.
attachment_instance_region_id	String	Region ID of the resource used as an attachment on the central network.

enterprise_router_site_code	String	Site code of the enterprise router on a central network.
specification_value	CentralNetworkAttachmentSpecificationValueInfo object	Additional information about an attachment.

**Table 7** CentralNetworkAttachmentSpecificationValueInfo
Parameter	Type	Description
enterprise_router_table_id	String	ID of the enterprise router route table.
attachment_parent_instance_id	String	ID of the parent resource of an attachment. Here it is the ID of the enterprise router.
hosted_cloud	String	Huawei Cloud or partner cloud. HWCloud: Huawei Cloud Ireland: partner cloud in Ireland
approved_state	String	Approval status. APPROVING: Approving APPROVED: Approved UNAPPROVED: Approval failed
reason	String	Reason for rejecting attachment creation.
