Cisco Catalyst WAN SDK for Python

Cisco Catalyst WAN SDK is a package for creating simple and parallel automatic requests via official SD-WAN Manager API. It is intended to serve as a multiple session handler (provider, provider as a tenant, tenant). The library is not dependent on environment which is being run in, you just need a connection to any SD-WAN Manager.

Important Notice: Early Beta Release

Welcome to the Cisco Catalyst WAN SDK!

We are thrilled to announce that Cisco Catalyst WAN SDK is now available in early beta. This is an exciting step forward in enabling developers to harness the full potential of Cisco's networking solutions. Please be aware that, as an early beta release, this version of the SDK is still undergoing development and testing. As such, it is provided "as is" and support to address any issues are limited and best effort.

Not recommend to use in production environments.

We encourage developers to explore and test the SDK's capabilities, but please exercise caution when using it in production environments. We are dedicated to improving the Cisco Catalyst WAN SDK and we value your input. Your feedback is crucial to us-it will guide us in refining and enhancing the SDK to better meet your needs. To report any issues, share your insights, or suggest improvements, please visit our Issues page on GitHub or reach out to us through the provided communication channels.

Thank you for being a part of our development journey!

Installation

pip install catalystwan

Manager Session

In order to execute SDK APIs ManagerSession needs to be created. The fastest way to get started is to use create_manager_session() method which configures session, performs authentication for given credentials and returns ManagerSession instance in operational state. ManagerSession provides a collection of supported APIs in api instance variable. Please check example below:

from catalystwan.session import create_manager_session

url = "example.com"
username = "admin"
password = "password123"

with create_manager_session(url=url, username=username, password=password) as session:
    devices = session.api.devices.get()
    print(devices)

ManagerSession extends requests.Session so all functionality from requests library is avaiable to user, it also implements python contextmanager and automatically frees server resources on exit.

Configure Manager Session before using (click to expand)

It is possible to configure ManagerSession prior sending any request.

from catalystwan.session import ManagerSession
from catalystwan.vmanage_auth import vManageAuth

url = "example.com"
username = "admin"
password = "password123"

# configure session using constructor - nothing will be sent to target server yet
auth = vManageAuth(username, password)
session = ManagerSession(url=url, auth=auth)
# login and send requests
session.login()
session.get("/dataservice/device")
session.close()

When interacting with the SDWAN Manager API without using a context manager, it's important to manually execute the close() method to release the user session resource. Ensure that the close() method is called after you have finished using the session to maintain optimal resource management and avoid potential errors.

Login as Tenant (click to expand)

Tenant domain needs to be provided in url together with Tenant credentials.

from catalystwan.session import create_manager_session

url = "tenant.example.com"
username = "tenant_user"
password = "password123"

with create_manager_session(url=url, username=username, password=password) as session:
    print(session.session_type)

Login as Provider-as-Tenant (click to expand)

Tenant subdomain needs to be provided as additional argument together with Provider credentials.

from catalystwan.session import create_manager_session

url = "example.com"
username = "provider"
password = "password123"
subdomain = "tenant.example.com"

with create_manager_session(url=url, username=username, password=password, subdomain=subdomain) as session:
    print(session.session_type)

Login using Api Gateway (click to expand)

from catalystwan.session import create_apigw_session

with create_apigw_session(
    url="example.com",
    client_id="client_id",
    client_secret="client_secret",
    org_name="Org-Name",
    username="user",
    mode="user",
    token_duration=10,
) as session:
    devices = session.api.devices.get()
    print(devices)

Threading (click to expand)

from threading import Thread
from catalystwan.session import ManagerSession
from catalystwan.vmanage_auth import vManageAuth
from copy import copy

def print_devices(manager: ManagerSession):
    # using context manager (recommended)
    with manager.login() as session:
        print(session.api.devices.get())

if __name__ =="__main__":

    # 1. Create shared authentication handler for user session
    auth = vManageAuth(username="username", password="password")
    # 2. Configure session with base url and attach authentication handler
    manager = ManagerSession(base_url="https://url:port", auth=auth)

    # 3. Make sure each thread gets own copy of ManagerSession object
    t1 = Thread(target=print_devices, args=(manager,))
    t2 = Thread(target=print_devices, args=(copy(manager),))
    t3 = Thread(target=print_devices, args=(copy(manager),))

    t1.start()
    t2.start()
    t3.start()

    t1.join()
    t2.join()
    t3.join()

    print("Done!")

Threading can be achieved by using a shared auth object with sessions in each thread. As ManagerSession is not guaranteed to be thread-safe, it is recommended to create one session per thread. ManagerSession also comes in with a default RequestLimiter, which limits the number of concurrent requests to 50. It keeps ManagerSession from overloading the server and avoids HTTP 503 and HTTP 429 errors. If you wish to modify the limit, you can pass a modified RequestLimiter to ManagerSession:

from catalystwan.session import ManagerSession
from catalystwan.vmanage_auth import vManageAuth
from catalystwan.request_limiter import RequestLimiter

auth = vManageAuth(username="username", password="password")
limiter = RequestLimiter(max_requests=30)
manager = ManagerSession(base_url="https://url:port", auth=auth, request_limiter=limiter)

Tenant migration (click to expand)

from pathlib import Path
from catalystwan.session import create_manager_session
from catalystwan.models.tenant import TenantExport
from catalystwan.workflows.tenant_migration import migration_workflow

tenant = TenantExport(
    name="mango",
    desc="Mango tenant description",
    org_name="Provider Org-Mango Inc",
    subdomain="mango.fruits.com",
    wan_edge_forecast=100,
    migration_key="MangoTenantMigrationKey",   # only for SDWAN Manager >= 20.13
    is_destination_overlay_mt=True,            # only for SDWAN Manager >= 20.13
)

with create_manager_session(url="10.0.1.15", username="st-admin", password="") as origin_session, \
     create_manager_session(url="10.9.0.16", username="mt-provider-admin", password="") as target_session:
    migration_workflow(
        origin_session=origin_session,
        target_session=target_session,
        workdir=Path("workdir"),
        tenant=tenant,
        validator="10.9.12.26"
    )

migration_workflow performs multi-step migration procedure according to Migrate Single-Tenant Cisco SD-WAN Overlay to Multitenant Cisco SD-WAN Deployment

Since 20.13 also MT to ST is supported (just provide suitable origin/target sessions, and is_destination_overlay_mt parameter)

Each step of the migration_workflow procedure can be executed independently using api methods: export_tenant, download, import_tenant, store_token, migrate_network

origin_api = origin_session.api.tenant_migration_api
target_api = target_session.api.tenant_migration_api
tenant_file = Path("~/tenant.tar.gz")
token_file = Path("~/tenant-token.txt")
# export
export_task = origin_api.export_tenant(tenant=tenant)
remote_filename = export_task.wait_for_file()
# download
origin_api.download(export_path, remote_filename)
# import
import_task = target_api.import_tenant(export_path, tenant.migration_key)
import_task.wait_for_completed()
# get token
migration_id = import_task.import_info.migration_token_query_params.migration_id
target_api.store_token(migration_id, token_path)
# migrate network
migrate_task = origin_api.migrate_network(token_path)
migrate_task.wait_for_completed()
