【NSO】NSO RESTCONF APIによるデバイスの設定

NSO RESTCONF API サンプルスクリプト

NSO RESTCONF API サンプルスクリプト

下記リンクをもとにNSO経由でのデバイスのコンフィグ取得、コマンド実行、コンフィグ設定、サービス作成を行うサンプルスクリプトを作成してみました。下記を参考にしています。

デバイスコンフィグ表示 (nso_get_device_config.py)

import requests
import json

requests.packages.urllib3.disable_warnings()

HOST = '**.**.**.**'
PORT = 8080
USER = 'admin'
PASS = 'admin'

def main():
	url = "http://{h}:{p}/restconf/data/tailf-ncs:devices/device=R3/config?depth=3".format(h=HOST, p=PORT)

	headers={'Content-Type':'application/yang-data+json',
		'Accept':'application/yang-data+json'}

	response = requests.get(url,auth=(USER,PASS),headers=headers,verify=False)

	print(response.text)

if __name__ == '__main__':
	main()

実行結果

$ python3 nso_get_device_config.py
{
  "tailf-ncs:config": {
    "tailf-ned-cisco-ios-xr:admin": {
      "fpd": {
        "auto-upgrade": {
        }
      },
      "disk_status_config": {
        "minor": 80,
        "severe": 90,
        "critical": 95
      },
      "memory_status_config": {
        "minor": 80,
        "severe": 90,

          "revision": "",

          "conformance-type": "implement"
        }
      ]
    }
  }
}

デバイスへのコマンド実行 (nso_exec_command.py)

import requests
import json

requests.packages.urllib3.disable_warnings()

HOST = '**.**.**.**'
PORT = 8080
USER = 'admin'
PASS = 'admin'

def main():
	url = "http://{h}:{p}/restconf/operations/tailf-ncs:devices/device=R3/live-status/exec/show".format(h=HOST, p=PORT)

	headers={'Content-Type':'application/yang-data+json',
		'Accept':'application/yang-data+json'}

	body={"show":{
		"args":"users"
		}
	     }

	response = requests.post(url,auth=(USER,PASS),headers=headers,data=json.dumps(body),verify=False)

	print(response.text)

if __name__ == '__main__':
	main()

実行結果

$ python3 nso_exec_command.py
{
  "tailf-ned-cisco-ios-xr-stats:output": {
    "result": "\r\n\rTue Jul 27 03:49:43.586 UTC\r\n   Line            User                 Service  Conns   Idle        Location\r\n   con0/RP0/CPU0   cisco                hardware     0  6d15h        \r\n*  vty0            cisco                telnet       0  00:00:07     192.168.1.1\r\nRP/0/RP0/CPU0:R3#"
  }
}

デバイスの設定 (nso_add_loopback.py)

import requests
import json

requests.packages.urllib3.disable_warnings()

HOST = '**.**.**.**'
PORT = 8080
USER = 'admin'
PASS = 'admin'

def main():
	url = "http://{h}:{p}/restconf/data/tailf-ncs:devices/device=R3/config/tailf-ned-cisco-ios-xr:interface/Loopback=10".format(h=HOST, p=PORT)

	headers={'Content-Type':'application/yang-data+json',
		'Accept':'application/yang-data+json'}

	body={ "Loopback": [
    			{
      			"id": 10,
      			"ipv4": {
        			"address": {
          				"ip": "1.1.1.1",
          				"mask": "255.255.255.255"
        			         }
      				}
            		}
          		]
		}

	response = requests.put(url,auth=(USER,PASS),headers=headers,data=json.dumps(body),verify=False)

	print(response.text)

if __name__ == '__main__':
	main()

実行結果
