HPE Aruba Networking Central Python Package

PyCentral (Python SDK for HPE Aruba Networking Central)

⚠️ Pre-release Notice
This is a pre-release version of PyCentral-v2, and the features are constantly being updated as the APIs evolve. This version of the SDK allows you to make API calls to New Central, GLP, and Classic Central.
If you are looking for the stable version of PyCentral (v1), it is still available and fully supported. PyCentral-v1, which only supports Classic Central, can be found here.

A Python SDK for interacting with HPE Aruba Networking Central via REST APIs.
Automate onboarding, configuration, monitoring, and management for:

• New Central
• HPE GreenLake Platform (GLP)
• Classic Central (via the classic module for backward compatibility)

Upgrading to this pre-release version will not break PyCentral-v1 code. All the PyCentral-v1 code has been moved to the classic folder within the PyCentral directory, ensuring backward compatibility. You can find Classic Central PyCentral Documentation here.

Install

To install the latest pre-release version of PyCentral, use the following command:

pip3 install --pre pycentral

If you already have PyCentral-v1 and would like to upgrade to the pre-release version, use the following command:

pip3 install --upgrade --pre pycentral

Authentication

New Central

You will need:

• Base URL or Cluster Name: Identifies your Central Account's API gateway. Both options function identically. Use whichever is convenient:
  • Base URL — URL for requests to your Central API Gateway. For instructions on how to locate your Base URL, see Finding Your Base URL in Central.
  • Cluster Name — Name of the cluster where your account is provisioned. A table detailing all cluster names can be found here.
• Client ID and Client Secret: These credentials are required to generate an access token to authenticate API requests. You can obtain them by creating a Personal API Client for your New Central Account. Follow the detailed steps in the Create Client Credentials documentation.

new_central:
  base_url: <api-base-url>
  client_id: <client-id>
  client_secret: <client-secret>

HPE GreenLake Platform (GLP)

If you are working with HPE GreenLake APIs, authentication is slightly different:

• GLP does not require a Base URL.
• You only need the Client ID & Client Secret for the HPE GreenLake Platform.

glp:
  client_id: <client-id>
  client_secret: <client-secret>

---

Example

Before running the script, create a token.yaml file in the same directory and populate it with the required credentials as follows:

new_central:
  base_url: <api-base-url>
  client_id: <client-id>
  client_secret: <client-secret>
glp:
  client_id: <client-id>
  client_secret: <client-secret>

Once you have the token.yaml file ready, you can run the following Python script:

import os
from pycentral import NewCentralBase

# Validate token file exists
token_file = "token.yaml"
if not os.path.exists(token_file):
    raise FileNotFoundError(
        f"Token file '{token_file}' not found. Please provide a valid token file."
    )

# Initialize NewCentralBase class with the token credentials for New Central/GLP
with NewCentralBase(token_info=token_file) as conn:
   
    # Make the API call to retrieve device inventory
    resp = conn.command(
        api_method="GET",
        api_path="network-monitoring/v1/device-inventory"
    )
    
    # If the response code is 200, print the device inventory response; otherwise, print the error code and message
    if resp["code"] == 200:
        print(resp["msg"])
    else:
        print(f"Error {resp['code']}: {resp['msg']}")

Run the script using the following command:

python3 demo.py

Compatibility

• v2 supports New Central and GLP.
• Classic Central (v1) remains in the classic module for backward compatibility.
• Existing v1 code will continue to work without changes.
