cisco_backup_jump_server

Python script using Netmiko to take a cisco config snapshot , via an intermediate jump server

Tested in python3.7

This script is useful for network engineers when there is a linux jump server ( jumpbox ) between the user

and the end cisco device, and eg corporate security controls prevent a direct ssh session.

Installation

Create a virtual environment eg called 'backup'

• python -m virtualenv backup

Activate the virtual environment

• backup\Scripts\activate.bat

Install Netmiko

• pip install netmiko

Verify with pip list

Usage

python backup_cisco.py

This script will call devices.txt and take a 'show run' config snapshot of each

cisco device in the list, writing each device config to a separate .txt file

It presumes there maybe different usernames/ passwords for the jump server vs the end device,

so it will initially prompt the user for all credentials.

It also presumes the user/pass is constant for all the devices in the txt file

Create a file devices.txt , a device ip address on every new line. see the example file in the repo to understand
the format required.Edit this list with your device's ip addresses

Have ready the creds for:

• Jump Server IP:
• Jump Server Username:
• End Cisco Device Username:
• End Cisco Exec Password:

getpass will hide the password screen input

Testing

You can use the Cisco Modelling Labs Enterprise sandbox

There is an example lab topology preloaded called "Multi Platform Network". This includes a devbox, some cisco devices and a few linux hosts

Known Issues

The RSA key in the jumpbox must match the RSA key in the end cisco device.

If this is not the case, then you may get a keygen error on trying to connect. The solution is to clear the key from the 'ssh/known_hosts' file

An example command would be ssh-keygen -R 10.10.10.1 where 10.10.10.1 is the ip of the end cisco device
