GNS3 Talks: Python for Network Engineers with GNS3 (Part 2) - Configure VLANs on switches.

[@haseebakhtar5048]

David i'm going to implement a Large Network automation first time in my country, and guess what those 10$ i spent on you course was the only money i spent. There are no words to pay my regards to you. I will always be great full. Thank you very much.

[@davidbombal]

Thank you for sharing! It is so nice to get feedback like this 😀

[@haseebakhtar5048]

hi David !!!, Now i want to optimize things and make them look more professional, i've taken your course on practical python cisco Network Automation and learned basic python on my own to pretty much automate all the routine tasks. can you please guide me where to go next, or which book to study to learn advance Network programming concepts which are deployed at companies like Facebook, Google, Amazon etc. I shall be thankful to you.

[@wilhelmtel794]

At a time, I had no idea why I chose a Python tutorial and today one year after and beginning my CCNA course, this is a nice suprise, I will now definitely try my luck on this.

[@davidbombal]

Great to hear!

[@bernardbain5302]

Fantastic tutorials David I have always avoided python but it appears to be the way forward for computer networks for the future, thanks for the simple straight forward easy to follow guidance.

[@Armurp01]

Loving the videos David.....enrolled in Mihai's GNS3 Python Course awhile back but have since transitioned my studies to CCIE......but watching these vids refreshes my memory on the scripting for Python..keep them coming.

[@davidbombal]

Thank you. CCIE or Python.... that is often a discussion point these days.... I think both is best :)

[@Armurp01]

Indeed ha

[@davidbombal]

Interesting talk from Cisco DevNet: CCIE versus Python: kzbin.info/www/bejne/iYHLmnyviNmBg6M

[@Armurp01]

Thanks for the link.......will listen :)

[@ibnuaufar7584]

amazing teach from you david, you make this looks easier :)

[@polliluiz]

Awesome video David. Keep up the good working. Really appreciate.

[@alifrazkhan124]

brilliant approach, covering the language from a network engineer's point of view concisely, very well done

[@hanen2699]

Thanks a lot David waiting for the next videos ..

[@davidbombal]

Thank you! More videos are now available in this series :)

[@kishorekannanp]

Thank you for the session David.

[@davidbombal]

Thank you for watching! More videos are now available in this series.

[@pppam]

A nice idea would be to show how to use ssh with python programming.

[@davidbombal]

Agreed. This may be part of the KZbin videos or my GNS3 Python course. I still need to decide where to put that content :)

[@deafnill]

It's not hard. You can use paramiko. There are other ways to do it, but that's the easiest module I've found.

[@237311]

Thanks for providing such a nice video. Where can I find the "How to use ssh with python prog.?

[@legendwarrior85]

Great video David !!!! Thanks for this initiative.. !!!!!

[@temoteocao5906]

Very informative! 👏👏👏👏

[@pavelejg5373]

Very interesting . David I see you use MacBook for networking. I’ve always been a Windows person but I’m considering to buy myself a MacBook but not sure . Would you recommend MacBook for someone who wants to take the network path combined with Python , Linux etc?

[@colinleocanna]

Thanks David. My print tn.read_all() statement is not printing out in my docker when I run the script. Using Solar Putty.

[@macgeraldbugay9647]

what version of GNS3 are you using and where did you get all the Cisco IOS that you've featured on this video?

[@maxc1530]

the complements (ubuntu, switchs, routers, etc) of gns3 are downloaded?

[@aakashbhavsar4620]

There seem to be two courses of your on udemy regrading python for network engineers which one should i buy?

[@princerai6773]

really good videos . very helpful for beginners.

[@davidbombal]

Thank you. I'm glad to hear the videos are useful :)

[@abdulravoofka363]

Many thanks. One great video to keep moving with network programming using python. Anyone managed to optimize the script using loops...

[@davidbombal]

Thank you Abdul. The next videos in the series look at ways to optimize the scripts.

[@komphatak3395]

Hi David, I have purchased your network automation course on Udemy. Can I use free Cisco Devnet CML for the network automation course or do I still have to purchase Cisco VIRL? Also the CML labs does not seem to have network automation container. If any of the general public knows the answer then please comment below. Thanks :-)

[@chraearnold1331]

What is the best software to use like GNS3 on my redmi note 5 pro

[@snly9715]

Your begging sounds make me crazy like my brain 🧠 has configurations! Thanks 🙏 Dave

[@Charger285]

whats the song in the beginning of the video sir?

[@skyblaze6687]

Is it server switching language which Create virtual network plz need ur reply to study more about it .Without knowing it's ins and outs it's frustrating to study

[@refaiabdeen5943]

Cheers Mate !!!

[@MOUHAMADOUCHERIFSAMBANDIAYE]

Hi Great video but I wanna know where can I find the iso image for gns3

[@discoveryinfo1993]

Thanks so much! It's very interesting :)

[@davidbombal]

Thank you. I appreciate the feedback :)

[@bernardbain5302]

Does anybody know how we can change the script to assign multiple ports to a single Vlan? I have assigned the ports but cant seem to assign multiple ports

[@SafarovTech]

Great video!!!!

[@davidbombal]

Thank you!

[@alanshar_]

Can you try make QinQ on Cisco by GNS3 ?

[@tarqjamil5755]

hi David Bombal I tried to run this script through windows 10 using python 3.6. But not working. Kindly help to get rip of this problem.

[@agaroui]

Thank you veryyyyyyy much Sir

[@davidbombal]

Its my pleasure!

[@braunbrelin982]

Can you please say how you created your GNS3 configuration? I am having trouble reproducing your examples in the video on my GNS3 setup.

[@davidbombal]

Devices used are Cisco VIRL IOSv and IOSv2 appliances. Also used the Ubuntu appliance. Have a look on my channel for examples on how to set those up if you are not sure. Also ask for help in the GNS3 community on the GNS3 site.

[@braunbrelin982]

Do you have a link to a specific video that will set up the environment for this video? Specifically, I'm having trouble in getting the ubuntu instance to talk to the outside internet and to the GNS3 router/switch devices.

[@davidbombal]

This video shows how to import the Ubuntu appliance: kzbin.info/www/bejne/n5qUqqGDrL2ce5o and here: kzbin.info/www/bejne/qKPNkmydf8-erLM - if you are having issues, ask in the GNS3 community here: gns3.com/community

[@gusmcknight6057]

thank you.

[@davidbombal]

Thank you for watching!

[@anthonyhenderson3189]

How do you get the educational versions of the IOS images?

[@davidbombal]

The only option Cisco have is to buy Cisco VIRL here: virl.cisco.com

[@kadiransari9722]

great thanks a ton

[@emoryharris384]

Why telnet and not SSH?

[@telethomson2036]

Hello, what is the name of the software you use to schematize your network ?

[@andrewcoleman3741]

If you're referring to the little diagram in the background, that's just GNS3 .

[@telethomson2036]

Thank you

[@SouravGoyal]

Please share use of SSH. Telnet is out ! now

[@davidbombal]

Have you watched all the videos in this series? SSH is covered later on.

[@psvpl]

I would optimize this script to read host address and commands from external file instead of all of these tn.write() functions and so much editing. I made similiar script in TCL/Expect.

[@davidbombal]

Agreed. Have a look at the next videos in the series where we optimize the script.

[@Huzaifahkhaan]

What is the the point here using python? Any how we have to type in the script instead of the router cli. Pls advice how is this going to save the time?

[@suchyysuchar]

It is going to save time when you have to configure this on 100 switches.

[@hackersatya2713]

this is mainly used to save engineering work. Like tracing the path between source and destination and Creating VIPs and Pools members in Load balancers

[@ashrasmun1]

I have no idea what's happening lol, KZbin recommended this to me even though I know jack shit about networking.

[@maomanemeshack1304]

David i am getting problem when i try to get device from cisco dnac ,when i sent this request (response = requests(url, auth=(username,password), headers =headers, verify=False).json() print(json.dumps(response)) python says (requests.exceptions.JSONDecodeError)
