DevNet 102: Network Automation Using Python

                        How to add  vlans on Multi-Switches  by python

Add commands to two switches:

ip name-server 8.8.8.8
ip domain name cloud.me
username ahmed password cisco
enable password cisco
line vty 0  4
login local
transport input all
exit
crypto key generate rsa
ip ssh version 2

Create text file contain IPs of switches:

root@kali:/home# vim myswitches.txt
192.168.23.100
192.168.23.101

Add VLANs on two switches by python script:

import paramiko
import time
import getpass

# Open file with list of switches
f = open("myswitches.txt")

# enter to each switch and configure it:
for line in f:
    ip_address = line.strip()
    username = raw_input("Enter your username of : " + ip_address + ": ")
    password = getpass.getpass()

    ssh_client  = paramiko.SSHClient()
    ssh_client.set_missing_host_key_policy(paramiko.AutoAddPolicy())
    ssh_client.connect(hostname=ip_address,username=username,password=password)

    print "Successful connection  " + ip_address

    remote_connection = ssh_client.invoke_shell()

    print "Configure vlans on  " + ip_address

    remote_connection.send('en\n')
    time.sleep(1)
    recv = remote_connection.recv(9999)

    remote_connection.send('cisco\n')
    time.sleep(1)
    recv = remote_connection.recv(9999)
    remote_connection.send("vlan database" + "\n")

    for n in range (2,12):
        print "Create VLAN " + str(n)
        remote_connection.send("vlan " + str(n) + " name Vlan_" + str(n) + "\n")
        time.sleep(0.5)

    remote_connection.send("exit\n")
    time.sleep(15)                          
    output  = remote_connection.recv(65535)
    print output
    ssh_client.close
