Netmiko Python Tutorial - Connecting to Cisco Router and Running Commands

In this video I will be using Netmiko to connect to a Cisco Router using SSH with Python.

Netmiko is a multi-vendor SSH Python library that simplifies the process of connecting to network devices via SSH. In this video I will use Netmiko to SSH to a Cisco router

Network Automation and Network Programmability is becoming more popular every day and the language leading this is Python.

Netmiko is a multi-vendor SSH Python library which makes connecting to network devices via SSH a breeze. This library adds some vendor specific logic to paramiko, which is the de-facto SSH library in Python.
The big question a lot of people ask is Netmiko or Ansible? And the answer to that question as always in IT is it depends.
it depends on how much you know about Python and how much you just want Ansible to take the strain or how complex or simple are the tasks you are completing.

Thank you, Roger. Your videos are the best on this subject. Your pace is just right, not like some others who lose as as students because they hurry as though they have to go to the bathroom.

Thanks a lot.. keep failing to parse nokia 7210 on my python, but now it works following your video :D

[wizardcoc]

Do appreciate you break down the steps to show how these command works individually before building a script. This helps very much.

[AhmedAli-dzhy]

Very clear and easy. You should have much more subscribers

[venuonduty]

Excellent, I like this video very much. And this made me to start coding again after a decade. Keep sharing

[allenxd]

subscribed thanks Roger. I am learning Python now to start automating. Great Vid!

[hdhillon]

Good explanation, please create more videos like this...thanks

[tolgayucel]

Your explanation is so clear. Are you going to keep recording new tutorials ? Subscribed !!

Note: I had to add an underscore character between the word "send" and the word "command" in the "connection.send command ("show ip interface brief")
in order for this to work. This is consistent with the list of available commands in the output of dir(connection) on my system. (I'm running Ubuntu 20.04 in WLS2 on Win 10.)

Thanks for your video. I’m new to Python and trying to use it for network automation learning. Please how can I loop through a list of network devices e.g [Router1, Router2] and apply different configurations (e.g, loopback0 to Router1 and loopback1 to Router2) from a txt. file to each of the devices in the list at each loop? Please help with code tips. Thanks.

[mIbrahim]

Thanks so much. So helpful ... Please how to print command in the output plus the result of command

[gufran.khan]

How we can pass multiple cmds? Can you share that as well?

[BharathKumar-mvbk]

Hi Im getting issue to by pass login for SG300switches . Can you address it how to by pass it .
Thanks

[kewlguyjason]

I'm guessing the answer is "use jinja2 templates" but what if we had to do deeper into the prompt, such as*interface* or *config-bgp* *config-ospf*, is it still possible to configure with just netmiko? I guess we would just have to change what we expect back from the router as the expect value (so not #) or just put in send_config_timing?

[brianachenbaugh]

wondering how to send different commands to different routers?

@RogerPerkin
Please provide me the link for the YT video for multiple device connection with Netmiko, which you mentioned in this video.

[emmanueloluwayemisi]

Am facing an issue with netmiko on ubuntu 20.04 connecthandler issue. not installed

[moemanm]

this was a very good video, thanks.
Out of netmiko, paramiko or ansible. which would you say is better for network automation.

When you have 2 or more devices, but one of them is not reachable the script cut all the entire process, how to make the process continues doesnt matter if there is one device unreachable?
