The truth is, I don’t write it from scratch. Just copy paste from some sources, and tweaked it a little bit. But the result is good.

Here you go.

import telnetlib
import time
import socket

#devices.txt contains an IP address on each line
with open('mydevices.txt','r') as f:
 ips = f.read().splitlines()

#print(ips)
#alternatively we can use a list
#ips=['10.1.1.10','10.1.1.20','10.1.1.30']


user = 'user1'
password = 'pass1'

#iterate through the list of devices and execute the same commands
for ip in ips:
 try:
 tn = telnetlib.Telnet(ip, timeout=7)

 tn.read_until(b'Username: ', timeout=7)
 tn.write(user.encode('ascii') + b'\n')

 if password:
 tn.read_until(b'Password: ', timeout=7)
 tn.write(password.encode('ascii') + b'\n')

 tn.write(b'enable\n')
 tn.write(b'ena1\n')
 # create snmp
 tn.write(b'configure terminal\n')
 tn.write(b'snmp-server community mySNMP ro\n')
 tn.write(b'end\n')
 # tn.write(b'terminal length 0\n')
 tn.write(b'sh run | i snmp\n')
 tn.write(b'exit\n')
 # exit command is mandatory to be able read using read_all()
 # result = tn.read_all().decode()
 line = tn.read_all().decode('ascii')
 print(line)
 tn.close()
 except:
 print((ip)+", timeout")
 pass

Beberapa hal yang perlu diketahui adalah:

Isi user dan pass sesuai keinginan Anda.
Jika perangkat menggunakan enable password, masukkan password yang sesuai, jika tidak menggunakan, bisa di uncomment.
File mydevices.txt berisi ip address perangkat. Isinya seperti dibawah.

192.168.255.11
1.1.1.1
192.168.255.10

Semoga bermanfaat.
