Huawei Cloud Cc Central Network Query

Huawei Cloud CC Central Network Query

Overview

This skill queries Huawei Cloud Cloud Connect (CC) Central Network resources using the hcloud CLI. Central Network is a core concept in Cloud Connect that enables global, centralized network architecture across regions and clouds.

Scope: Query only — no create, update, or delete operations.

Resources covered:

Note on attachments: Central network attachments come in two types — ER Route Table and GDGW. There is no generic "show attachment" command; you must use the type-specific command based on the attachment type.

Note on connection show: There is no dedicated ShowCentralNetworkConnection API. To query a single connection, use ListCentralNetworkConnections with the --id.1 filter, or read the connections array embedded in the ShowCentralNetwork response.

Out of Scope (不覆盖的能力):

The following Central Network capabilities are not covered by this skill. If the user requests any of these, inform them clearly that the skill does not support it.

If a user asks for 策略查询 / 策略管理 / 配额查询 / 能力查询 / 标签管理, tell them this skill does not cover these capabilities and suggest using the hcloud CLI directly.

Prerequisites

1. hcloud CLI installed and authenticated. See references/cli-installation-guide.md.
2. IAM permissions: cc:centralNetworks:list and cc:centralNetworks:get. See references/iam-policies.md.
3. Region: Central Network is a global service — use any region where CC is available (e.g., cn-north-4).
4. Domain ID: Most commands require --domain_id (account ID). Obtain from IAM → My Credentials.

Workflow

1. Identify the target central network (List → pick by name/id)
2. Query details as needed:
   ├── Instance details → ShowCentralNetwork
   ├── Attachments → ListCentralNetworkAttachments → Show by type
   └── Connections → ListCentralNetworkConnections → filter by id for single

Core Commands

1. List Central Network Instances

hcloud CC ListCentralNetworks --cli-region={region} --domain_id={domain_id} [optional filters]

格式说明模板，不可直接执行 — 将 {region}、{domain_id} 等占位符替换为实际值后执行。

Key parameters:

Example:

hcloud CC ListCentralNetworks --cli-region=cn-north-4 --domain_id=xxx --limit=10

2. Show Central Network Instance

hcloud CC ShowCentralNetwork --cli-region={region} --domain_id={domain_id} --central_network_id={central_network_id}

格式说明模板，不可直接执行 — 将 {region}、{domain_id}、{central_network_id} 等占位符替换为实际值后执行。

Key parameters:

Example:

hcloud CC ShowCentralNetwork --cli-region=cn-north-4 --domain_id=xxx --central_network_id=cn-xxx

The response includes an embedded connections array with CentralNetworkConnectionInfo objects — useful for viewing all connections without a separate call.

3. List Central Network Attachments

hcloud CC ListCentralNetworkAttachments --cli-region={region} --domain_id={domain_id} --central_network_id={central_network_id} [optional filters]

格式说明模板，不可直接执行 — 将 {region}、{domain_id}、{central_network_id} 等占位符替换为实际值后执行。

Key parameters:

Example:

hcloud CC ListCentralNetworkAttachments --cli-region=cn-north-4 --domain_id=xxx --central_network_id=cn-xxx --limit=10

4. Show Central Network Attachment (by type)

There is no generic show-attachment command. Use the type-specific command based on the attachment type.

4a. Show ER Route Table Attachment

hcloud CC ShowCentralNetworkErRouteTableAttachment --cli-region={region} --domain_id={domain_id} --central_network_id={central_network_id} --er_route_table_attachment_id={attachment_id}

4b. Show GDGW Attachment

hcloud CC ShowCentralNetworkGdgwAttachment --cli-region={region} --domain_id={domain_id} --central_network_id={central_network_id} --gdgw_attachment_id={attachment_id}

格式说明模板，不可直接执行 — 将 {region}、{domain_id}、{central_network_id}、{attachment_id} 等占位符替换为实际值后执行。

How to determine attachment type: Run ListCentralNetworkAttachments first — the response includes attachment_instance_type (GDGW or ER_ROUTE_TABLE) and the corresponding attachment ID for each entry.

5. List Central Network Connections

hcloud CC ListCentralNetworkConnections --cli-region={region} --domain_id={domain_id} --central_network_id={central_network_id} [optional filters]

格式说明模板，不可直接执行 — 将 {region}、{domain_id}、{central_network_id} 等占位符替换为实际值后执行。

Key parameters:

Example:

hcloud CC ListCentralNetworkConnections --cli-region=cn-north-4 --domain_id=xxx --central_network_id=cn-xxx --limit=10

6. Show Single Central Network Connection

No dedicated ShowCentralNetworkConnection API exists. Use the list command with an ID filter:

hcloud CC ListCentralNetworkConnections --cli-region={region} --domain_id={domain_id} --central_network_id={central_network_id} --id.1={connection_id}

格式说明模板，不可直接执行 — 将 {region}、{domain_id}、{central_network_id}、{connection_id} 等占位符替换为实际值后执行。

Alternative: The ShowCentralNetwork response embeds a connections array containing CentralNetworkConnectionInfo objects — you can find the target connection there without a separate call.
