Can't run API calls against DNA-C sandbox hardware reservation

dwrice000 · ‎04-07-2020

I know that the always an DNA-C sandbox is read-only but I thought the reservation DNA-C sandboxes are full read-write. However, I've tried on two occassions to run the following basic API call and it always times out however I can hit the web GUI via https and telnet to port 443 from the command-line where I'm running the script below:

#!/usr/bin/env python

import requests
import urllib3
import json
from dnacentersdk import api

def main():

  urllib3.disable_warnings()
  dnac = api.DNACenterAPI(
    base_url="https://10.10.20.85",
    username="admin",
    password="Cisco1234!",
    verify=False,
  )

  devices = dnac.devices.get_device_list()

  for device in devices["response"]:
    print(device["managementIpAddress"] + " " + device["id"] + " " + device["type"])

if __name__ == "__main__":
  main()

Is this just a temporary issue or am I doing something wrong?

Thanks!

Hi

What error message do you get if any?

I don't have a screenshot of the exact message but the Python exception was a network timeout message as if it could never complete the connection. Does my simple code above work for you against a HW sandbox reservation?

EDIT: Actually found the text of my error:
