Cisco Catalyst WAN SDK for Python

Cisco Catalyst WAN SDK is a package for creating simple and parallel automatic requests via official 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 Manager.

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

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

# configure session using constructor - nothing will be sent to target server yet
session = ManagerSession(url=url, username=username, password=password)
# 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)

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()

Note:

To remove InsecureRequestWarning, you can include in your scripts (warning is suppressed when catalystwan_devel environment variable is set):

import urllib3
urllib3.disable_warnings(urllib3.exceptions.InsecureRequestWarning)

Catching Exceptions

try:
    session.api.users.delete("bogus-user-name")
except ManagerHTTPError as error:
    # Process an error.
    print(error.response.status_code)
    print(error.info.code)
    print(error.info.message)
    print(error.info.details)
