This video demonstrates how to take Cisco IOS device configuration backup from the terminal using netmiko and save the file with timestamp.
from netmiko import ConnectHandler
from netmiko.ssh_exception import NetMikoTimeoutException
from paramiko.ssh_exception import SSHException
from netmiko.ssh_exception import AuthenticationException
import time
import datetime
TNOW = datetime.datetime.now().replace(microsecond=0)
IP_LIST = open('15_devices')
for IP in IP_LIST:
print ('\n '+ IP.strip() + ' \n' )
RTR = {
'ip': IP,
'username': 'admin',
'password': 'admin1',
'device_type': 'cisco_ios',
}
try:
net_connect = ConnectHandler(**RTR)
except NetMikoTimeoutException:
print ('Device not reachable.')
continue
except AuthenticationException:
print ('Authentication Failure.')
continue
except SSHException:
print ('Make sure SSH is enabled in device.')
continue
print ('Initiating cofig backup')
output = net_connect.send_command('show run')
SAVE_FILE = open("RTR_"+IP +'_'+ str(TNOW), 'w')
SAVE_FILE.write(output)
SAVE_FILE.close
print ('Finished config backup')
