Thanks David you made it so easy for me to backup my configs now. And as a side note that was a nice Black Mamba sighting. I stay in South Africa and do not see them often.
Thanks Johan. That was near Bela Bela (Mabalingwe Game Reserve). We saw it multiple times and it was a bit too close for comfort.... not sure I'd want to see it again any time soon.
Thank You David, I admire you as a professor and as a human being. I'm new in the IT field but I have a couple of months watching your videos and I bought your Udemy CCENT course a couple of weeks ago (to start my Network Engineer path and pass the CCNA) and I love it. You are always very humble despite you are an expert in your field and always trying to help and motivate us in many ways to become better professionals and better human beings... That is, pure humble and GREATNESS in you, GOD bless you!
Wasn't sure I was in the right place when the video started, but I'm glad I stuck around :) . Great demo on kron jobs for those of us who are too lazy to go read Cisco docs!
These videos are a great additional help to abide by the time management videos made last December. No one should repeat new years hopes every year, and a healthy obsession from many sources after work puts anyone on the rise
This is pretty cool, didn't know about this feature. I think ultimately it's better to have it all running from a central location so you can track the status of backups etc. Unless you wrote a script to check the tftp folder every day for the right amount of files. Cheers for the vid
Hello David, cool video as of always. Like others have suggested any chance if you get the time for some Ansible and/or advanced IP SLA''s would be highly appreciated
Python programming language has nothing to do with snakes. "Python's name is derived from the British comedy group Monty Python, whom Pythoncreator Guido van Rossum enjoyed while developing the language." Wikipedia ... anyways great material. Thanks David!
David, wonderful video! I would however like to see how you can get archive to work with SCP, as most are going away from insecure protocols. Again, another wonderful video!
Hi David Bombal! I have been following you for a while and I very much appreciate the high quality content material you create. One of things that I'm trying to mimic but cannot seem to find any answer (maybe I did see it but I don't realize it) is how to add/integrate python to gns3. Sure I can download it on Win10 but from what I'm seeing, it's within gns3. Maybe I'm wrong but I'm totally confused. I want to learn and experiment with python but this is my road block. Do you think you can create a video on how to add/integrate python from scratch? Or if you do have a video, may you direct me? Again, thanks a lot for the material and clarity you bring!!
awesome video! I wish I would have seen this about two months ago... would have saved me a crap ton of time! your a networking god David! :) Can you tell me where you got those GNS3 images for your network devices?
Hello sir, thank you so much for this video. This is exactly what I was looking for. But can you please advise how I can take the backup in the local machine itself without using the tftp server as I don't have a tftp server installed.
Thanks a lot, sir! This is exactly what I was looking for! But I have a doubt with kron, can we add a number or date to the file name? for example, R1-config1, R1-config2, R1-config3, or, R1-config-30_10_2020, etc.
Very good video. I want to ask you about archive and log config. What is this about? Will this log will be sent somewhere or its in the flash? I am sorry for my question but im new in this
hey david i would love to see a python Video, which shows: get config with ncclient convert to dict change config convert it back upload to it back via ncclient if you don't answer this comment, i will ask you on the cisco live in Barcelona next year 😜
Can python be used to push this out to all the routers and switches on the network, so that we don't have to manually add it to each one ? This is exactly what I was looking for. Now wondering how to deploy it to all devices efficiently. Thank you
Thanks for your great video! Is there a such way to schedule import that archived config file to another cisco switch for redundancy, i would like to have two same cisco switch with exactly same config file.
Good morning I have a problem with my Cisco SF500-48p switch the archive command does not work in this version of switch and even the kron command THANKS
Thank you For you +Positivity! Is there any way to archive also show Commands! if yes How? Remarque: Even in config priviledge mode with #Do, the shows are not archived! Cordially.
Hi David, wanted to find out what books and sites(blogs) would recommend an up and coming engineer to be reading in order to improve their networking skills? regards
Any specific technology area? There are many good books, but there is a wide range of topics in networking. Two good sites are packetpushers.net and ipspace.net
Is a nice video, thanks for this. I'm triying to replicate the configuration but for some reason I can not assign an IP address to the toolbox. Would you please giveme son light.
No one is going to automate backing up just one router or switch. I was really hoping that you would shown how this work in an environment that has dozens or hundreds of switches. When you switched to a scheduled backup, there seemed to be no mention of the file name - only the date/time stamp. What happens when you program kron on multiple devices and point it to a TFTP server? How do the filenames show up? Still, you presented a worthy subject as I am just starting a position in which there are no local backup of switch configs but probably 100 switches.
Do they have a solarwinds ? You can bring the configs backups to the solarwinds. The place where i am working we do save the config backups in solarwinds and i am presently working to add some nodes in solarwinds and also be able to bring the configs to solarwinds.
No. This was just a demonstration showing you that you don't need Python for every situation. I would still use Python for lots of things including backups if that is something you prefer doing.
Hi David, is there some possibility to do automatic backup of startup config from Cisco SG550X swich where kron/archive command is not available? Thank You, regards.
Hi David, Thanks for taking the time to make this video. I am having an issue that wasn't mentioned. You mention tftp: ftp: and scp: synonymously, but I am unable to implement scp in an automated fashion. I have established connectivity, and can use scp: by manually supplying a password using the URL "@:/", which then requires a password to be entered manually. If I try to include password ":@:/", to automate, the login fails. Interestingly, this syntax works fine on ASA, but not any version IOS or IOS-XE. I opened a TAC case and was told IOS or IOS-XE have never supported inclusion of password, and the only automated way of using a secure protocol is with Prime. Do you know of any way to securely backup configurations automatically? Thanks in advance!
very nice, I think I can make a good use of the show run copy with php to publish for my supervisor so that he can view info such as IOS version or port status. I am managing more than 1000 switches and routers at the same time. Any suggestion?
On Linux you could use diff like this: root@Ubuntu:/tftpboot# diff R1--Sep-14-20-11-00.018-0 R1--Sep-14-20-11-41.350-3 3c3 < ! Last configuration change at 20:10:53 UTC Sat Sep 14 2019 --- > !

What do you think about more challenging languages like C/C++ and do they have any application to you or network engineers? Python is made of C. EIGRP/OSPF/iOS/junOS are C++. Also C++ is a lower level language more directly for the chip & RAM with speed gains, giving employees a greater idea of their work & craft. There is a school of thought by dev leads that Python is easy that babies can do it, and C is for REAL programmers. What is your impression of Python & C?
Mr. Bombal regarding the change of cisco certificate as i remember u told me once that I have time till February 2020, but what if i wanted to do my CCNA exam after that date? can i do it or i'll have to take a different course? knowing that my CCNA course that i took was 200-125
CCNA changes in Feb 2020. If you pass the current CCNA before that date, you will get the new CCNA as well. If you wait you will need to take the new course and exam, but there is overlap of content so it should not be that difficult.
Thanks David you made it so easy for me to backup my configs now. And as a side note that was a nice Black Mamba sighting. I stay in South Africa and do not see them often.

I used the Kron occasionally but I didn't know about the Archive. Thanks for the good information. David!
Nice options for automated backups. I myself use rancid and CVS from a Linux box where I can see the difference between configs on a webpage.
Great example Marc. I'll be creating more videos showing how to do this type of thing with Python and Ansible etc.
i follow your video in linkedin learning, thats so awesome, please continue your video also in linkedin learning.

Yes, it's simple way to backup configs..... thank you...
Glad you found the video useful Nishanth
Yes Sir..can you do video on loopback interfaces on routers... Thanks

Another interesting way to grab or backup configs is using a RW community and performing an SNMPWALK
Much needed one! Thanks David 👍

The easiest way is to drag the Network Automation container into your GNS3 topologies. That has Python built in.

How do you push the configs to a specific file on the TFTP server
We used this method in our production and some devices show high cpu utilization
Which method Praveen? kron or archive? Which devices and which versions of Cisco IOS?
