DNAC API - get device IDs by list of hostnames with /network-device

vbui6 — Mon, 18 Sep 2023 13:29:45 GMT

Hi all,

I'm trying to receive a list of network IDs with a single python query: dna/intent/api/v1/network-device based on a list of approx. 300+ hostnames.

So far I tried to use a single array or a single string: 'hostname': ','.join(hostnames).

Is the API capable of processing multiple hostsnames? If yes, How is the Syntax? I want to prevent a solution, which needs to process a query for every single host.

Thank you 🙂

If you query the endpoint without the hostname parameter, you'll get all devices. With this info you can build for example a hostname to ID dict (assuming the hostname is unique):

import requests requests.packages.urllib3.disable_warnings() import json dnac = "sandboxdnac.cisco.com" user = "devnetuser" password = "Cisco123!" r = requests.post(f"https://{dnac}/dna/system/api/v1/auth/token", auth=(user, password), verify=False) if r.ok: token = r.json().get("Token") r = requests.get(f"https://{dnac}/dna/intent/api/v1/network-device", headers={"X-Auth-Token": token}, verify=False) if r.ok: hostname2id = {} for dev in r.json().get("response"): print(f"hostname: {dev.get('hostname')} ==> ID: {dev.get('id')}") hostname2id[dev.get("hostname")] = dev.get("id") # print all print(json.dumps(hostname2id, indent=1)) # get id for specific hostname print(f"id for sw3 is {hostname2id.get('sw3')}") else: print("Error while getting infos from DNAC API") exit(1)

Output:

{ "sw1": "32446e0a-032b-4724-93e9-acbbab47371b", "sw2": "c069bc2c-bfa3-47ef-a37e-35e2f8ed3f01", "sw3": "5f03d9a9-33df-450e-b0c3-6bcb5f721688", "sw4": "826bc2f3-bf3f-465b-ad2e-e5701ff7a46c" } id for sw3 is 5f03d9a9-33df-450e-b0c3-6bcb5f721688
