Gather information from Switches using Python - Network Programmability

 In this post, I'm going to use Python and Telnet Library to login into a list of IP addresses and execute some commands and send the output to separated text files.

 

 My network contains HP access switches and I need to collect some information like product number or serials from each IP in the file called (hpswitch.txt).

ok, let's start

 

#!/usr/bin/env python
import getpass
import telnetlib

user = ("Admin")
password = ("password")

f = open ("C:\\Users\\user.name\\Desktop\\python\\hpswitch.txt")

for line in f:
    print "Getting Serials from Device  " + (line)
    HOST = line.strip()
    tn = telnetlib.Telnet(HOST)

    tn.read_until("Username:")
    tn.write(user + "\n")
    if password:
        tn.read_until("Password:")
        tn.write(password + "\n")


     #this section is the switch configuration part
    tn.write("super \n")
    tn.write("password\n")
#tn.write("system-view \n")

    tn.write("dis dev manu | in JD368B\n")


    tn.write("quit\n")
#tn.write("quit\n")
    readoutput = tn.read_all()


    saveoutput = open("C:\\Users\\user.name\\Desktop\\serials\\switch" + HOST + ".txt", "w")


    saveoutput.write(readoutput)
    saveoutput.write("\n")
    saveoutput.close

print tn.read_all()

 =================================================================

 

Same code can be used for checking interfaces or uplinks states.
