Python与Cisco

以下代码测试单个子网循环的方法:

#!/usr/bin/python

from netmiko import ConnectHandler

from netmiko.ssh_exception import NetMikoTimeoutException

from IPy import IP

import time

import sys

import getpass

import re

import io

import StringIO

class Cisconetwork():

def __init__(self,username,password):

self.username = username

self.password = password

def CiscoDevice(self,iplist):

self.device={'device_type':'cisco_ios',

'username':self.username,

'password':self.password,

'ip':iplist

}

print('-'*100)

print "[+]connect to network device... %s" %(iplist)

self.connect = ConnectHandler(**self.device)

self.connect.enable()

def gethostname(self):

self.hostname = self.connect.find_prompt()

self.hostname = self.hostname.replace("#","")

print self.hostname

def interfaceInfo(self,cmd):

result = self.connect.send_command(cmd)

for interface in result.split('n'):

if 'up' in interface:

#print interface

lines=StringIO.StringIO(interface)

data = lines.read()

intername = ' '.join(re.findall('^Eth.+/d',data))

loopback = ' '.join(re.findall('Loopback[0-9]',data))

interIP = re.findall( '.'.join(['d{1,3}']*4),data)

if intername:

print intername ,':', ''.join(interIP)

else:

print loopback , ':', ''.join(interIP)

def show(self,cmd):

result = self.connect.send_command(cmd)

lines = StringIO.StringIO(result)

data = lines.read()

uptime = re.findall('uptime.+',data)

id = re.findall('d{8}',data)

soft = re.findall('L3_.+\.bin',data)

print 'Device UPtime:', ''.join(uptime)

print 'Device ID:', ''.join(id)

print 'Soft Version:',''.join(soft)

def close(self):

if self.connect is not None:

self.connect.disconnect()

self.connect = None

print '[+] Network devices complete all settings!'

if __name__ == '__main__':

print "[+] This Program is beging done......."

#username = raw_input('Username:')

#password = getpass.getpass()

ipadd = IP('10.0.0.0/30')

for ips in ipadd:

ipadds = StringIO.StringIO(ips)

ipadds = 'n'.join(ipadds).splitlines()

for iplist in ipadds:

try:

switch = Cisconetwork('admin','Password.123')

switch.CiscoDevice(iplist)

switch.gethostname()

switch.interfaceInfo('show ip int brief')

switch.show('show version')

switch.close()

except (EOFError, NetMikoTimeoutException):

print('Can not connect to Device!')

如何是多个子网需增加多一层循环，代码更改如下：

if __name__ == '__main__':

print "[+] This Program is beging done......."

#username = raw_input('Username:')

#password = getpass.getpass()

ipadd = IPSet([IP('10.0.0.0/30'),IP('10.0.1.0/30'),IP('10.0.2.0/30')])

for ips in ipadd:

ipadd = StringIO.StringIO(ips)

ipadds = 'n'.join(ipadd).splitlines()

for ip01 in ipadds:

ip02=IP(ip01)

for ip03 in ip02:

ip03 = StringIO.StringIO(ip03)

ip03 = 'n'.join(ip03).splitlines()

for iplist in ip03:
