Get networks from IPAM and add to NetMRI for Discovery

So a customer that has been running Infoblox IPAM for a while wanted to start using NetMRI to discover most of their networks but didn’t want to manually enter in every network again.

Solution:

Use Python with in NetMRI to make a “request” call to their IPAM and create the networks automatically

The way we approach this problem since we didn’t want to add all the networks that are currently in IPAM to NetMRI for Discovery.  We decided to use Extensible Attributes in IPAM called “NETMRI” and set the value to “Add” and once the network was added to NetMRI we would update the EA-NetMRI to “Done”

The next two pictures will show before I run the script:

IPAM:

NetMRI:

This is the following script that will make the changes:

import requests
import json

requests.packages.urllib3.disable_warnings()

gm_user = "admin"
gm_pwd = "infoblox"
url = "https://192.168.0.200/wapi/v2.7/"
s = requests.Session()
s.auth = (gm_user, gm_pwd)
mri_url = "192.168.0.201"
mri_user = "admin"
mri_pwd = "netmripassword"

def get_networks_to_add():
    # We are going to search an EA called NetMRI and look for any value of ADD
    querystring = {"_return_fields+": "extattrs", "*NetMRI:": "Add"}
    # We are using the API Network method
    url2 = url + "network"
    response = s.get(url2,  params=querystring, verify=False)

    if response.status_code == 200:
        return json.loads(response.content.decode('utf-8'))
    else:
        return None


def add_network_mri(net_new):
    url3 = "https://" + mri_url + "/api/3.3/discovery_settings/create"
    payload = "{\n\t\"range_value\" : \"" + net_new + \
        "\",\n\t\"range_type\" : \"CIDR\",\n\t\"discovery_status\" : \"INCLUDE\"\n}"
    headers = {'Content-Type': "application/json"}
    response = requests.post(url3,  data=payload, verify=False,
                     auth=(mri_user, mri_pwd), headers=headers)
    if response.status_code == 201:
        return json.loads(response.content.decode('utf-8'))
    else:
        return None

def update_network_ea(ea):
    url1 = url + ea
    payload = "{\"extattrs\": { \"NetMRI\": { \"value\": \"Done\"}} }"
    headers = {'Content-Type': "application/json"}
    response = s.put( url1,  data=payload, verify=False, auth=(gm_user, gm_pwd), headers=headers)

    if response.status_code == 200:
        return json.loads(response.content.decode('utf-8'))
    else:
        return None


account_info = get_networks_to_add()
#print(account_info)
if account_info is not None:
    print("Found the following network(s) will be added to NetMRI: ")
    for k in account_info:
        new_net_mri = k['network']
        add_netmri = add_network_mri(new_net_mri)
        if add_netmri is not None:
            print("[+] Added network " + new_net_mri + " for discovery")
            ea = k['_ref'] 
            done = update_network_ea(ea)
            if done is not None:
                print("[+] Updated EA for " + k['network'])
            else:
                print('[-] EA Update Request Failed' )
        else:
                print('[-] Update to NetMRI Failed' + k['network'])


else:
    print('[-] Request Failed')
