This video demonstrates how to take cisco routers / switches terminalbackup to file using Python 3

Using Open method in python


import paramiko
import time
from getpass import getpass
import datetime

TNOW = datetime.datetime.now().replace(microsecond=0)

username = 'admin'
password = 'admin'


DEVICE_LIST = open ('09_devices')
for RTR in DEVICE_LIST:
RTR = RTR.strip()
print ('\n #### Connecting to the device ' + RTR + '####\n' )
SESSION = paramiko.SSHClient()
SESSION.set_missing_host_key_policy(paramiko.AutoAddPolicy())
SESSION.connect(RTR,port=22,
username=username,
password=password,
look_for_keys=False,
allow_agent=False)

DEVICE_ACCESS = SESSION.invoke_shell()
DEVICE_ACCESS.send(b'terminal len 0\n')
DEVICE_ACCESS.send(b'show run\n')

time.sleep(5)
output = DEVICE_ACCESS.recv(65000)
print (output.decode('ascii'))
SAVE_FILE = open('ROUTER_' + RTR + str(TNOW), 'w')
SAVE_FILE.write(output.decode('ascii'))
SAVE_FILE.close

SESSION.close
