NetMRI - Customized Configuration Collection

Customized Configuration Collection

  • This is an API enhancement that enables the customer to script their own configuration collection.  This means that unsupported devices can have change management and configuration policy audits supported.  This went in specifically for a customer that wanted policy checks done on SD-WAN Viptela routers.

 

The Script:

# BEGIN-SCRIPT-BLOCK
#
# Script-Filter:
#     true
#
# END-SCRIPT-BLOCK

import requests
#
# Stops us from erroring out when making a request call to a Self Signed Cert
#
requests.packages.urllib3.disable_warnings()
#
# "netmri_ipaddress" is a well known variable of your NetMRI
# I broke up the API version and the API call
#
api_v = "/api/3.3"
api_command = "/config_revisions/import_custom_config"
url = "https://"+ netmri_ipaddress + api_v + api_command
#
# Below I statically define the "DeviceID" which is "2" in this example this is my "Home Router" :)
# We are going to add the following to 'RunningConfig': 'Testing 123456','SavedConfig': 'Testing 654321'
#
payload = {'DeviceID': '2', 'RunningConfig': 'Testing 123456','SavedConfig': 'Testing 654321'}

#
# We are going to use the "Username" and "Password" you logged in with for the API call
# http_username and http_password
#
r = requests.get(url, auth=(http_username, http_password), data=payload, verify=False)


Now for the fun stuff, we run the script

Now to back up a device that we do not support

Install Process

 

  • SSH into the NetMRI and run “sandbox login”
  • Login with sbuser/sbuser (you might have to change the password)

 

  • Installing PIP(PIP is not installed by default)

 

 

  • python3 get-pip.py

  • This will run and download the binary of PIP and install it

 

 

  • pip install paramiko

  • Note - Paramiko
    • The high-level client API starts with the creation of an SSHClient object. For more direct control, pass a socket (or socket-like object) to a Transport, and use start_server or start_client to negotiate with the remote host as either a server or client.

 

This following slide is one script that will “SSH” to a device you have selected and login via the “username” and “password” you supplied.

For this example, I’m just using a basic show command “show ip int brief”.

This is what the running Config Saved looks like

Very nice, Sif!

Do you know if the downloaded pip and paramiko will get wiped when performing a NetMRI upgrade.  I.E., will the sandbox get recreated or just updated?

I'm not sure, let me test it in my lab and post the results.

Ok so I just upgrade from 73.1 to 7.3.2, PIP and my modules are still working great Smiley Happy

 

Keep in mind I'm running a VM NetMRI and a VM Sandbox
