Python | Netmiko | Auto ping

Question

First, let me tell you that I am a novice and I have tried the below code :

conn = netmiko.ConnectHandler(ip='10.254.60.10', device_type='cisco_ios', 

                                username='user', password='P@ssw0rd')

print (conn.send_command('show interface Ethernet0/0 | i line|Des|Int'))

output like this

Ethernet0/0 is up, line protocol is up Description: CUSTOMER A

The Internet address is 10.254.60.69/30

I want to know how can I auto ping it to IP PtP with the help of conn.send_command() based on the result of the show interface command?

example ping to 10.254.60.70

Answer 1

Let's suppose this is your text:

text = '''Ethernet0/0 is up, line protocol is up Description: CUSTOMER A

Internet address is 10.254.60.70/30'''

and you have the below IP/MASK using string functions:

address = text.split(' ')[-1]

print(address)  # 10.254.60.70/30

and then you can use the usual module ipaddress package:

import ipaddress

net = ipaddress.ip_interface(address)

ip = str(net.network.broadcast_address)

print( ip )   # 10.254.60.71 

Or you can also use the netaddr module:

import netaddr

net = netaddr.IPNetwork(address)

ip = str(net.broadcast)

print( ip )   # 10.254.60.71
