It took about 30 seconds from the time you got into the CLI, did not know about ^ or $. Then the hits kept on coming, ending with reload in, very nice! Thank you!
Great video! I wish I had this type of content during my CCNA studies. Regular expressions in CLI are life savers, for example one of my favourite commands is: show spanning-tree detail | include occur|from I can clearly see where and when did the last MSTP topology change occur. However, the best IOS commands are those which are not documented ;)
David, Sir! Awesome, clear and concise explanations. Detailed and informative. I take notes and do screen grabs to paste in my notebook, makes a wonderful reference guide for when I do get the role, in which they'll want me performing telnets or SSH'es to routers and switches. Awesome stuff, keep it coming Sir and THANK YOU!
All videos you publish without exceptions I learn something from you David ,( thats what i love from your videos, no matter the topic you always show me something new ), this time since the minute 2:10 got into something i didn't knew and i found the default interface great!! and was lucky enough to get a copy of the Python Course =) Thank you for everything.
Thank you David. it was always said to me at the end Staffordshire university 2017 when i got my degree that "keep learning" and this is what you are achieving for me and i know you are doing this for others!!!
It's good advice - especially in this industry. The only way to survive and get ahead is to keep on learning. Really happy to know my videos are helping you do that :)
Your videos as usual are very very informative. I am pretty happy to be able to know how to use '?' in a regex while in the interactive CLI. Also your videos with Hank is another great stuff for us to get deeper into the world of APIs.
I found that default interface command about a month ago and it has made things a lot more simple. The 'linenum' command is awesome. I work in a team with 2 other guys and it is frustrating trying to communicate exactly what I am looking at and trying to explain them. This will make it much more streamlined.
David..you’re the best! How I wish I could meet you in person.. such a great educational video you put here...never knew cisco ios can do such thing. Thanks David!
Wow! Thanks David for the free course! I appreciate it! I recently failed my ICND2, I got to question 47 of 55 with a score around 768, meaning if I had been quicker I would have passed, I need more guided hands on experience... Thanks again!
Thanks for another great video David, didnt know about those commands... Also i did get the free copy of Python so im gonna look into that, thanks alot!
Woah! Very interesting. I own your CCNA fundamentals course and I have to say that you have helped me a lot to study for my certification! Thanks for sharing with us your knowledge because I think you make study a little bit easier! 😄
I knew some of the commands but not used them in the combination to better specify the output. Great content 👍. P. S. Bought 1 of your Udemy class and it also offered 3 additional classes for FREE 😃(Great Value). Thank you Sir!
David, love your deep dives on what some consider to be mundane commands like show run. $|^ seem to get passed over by a lot of people. Knowing these things make engineers a lot faster in the CLI. One request however, and lets use 'show run linenum' as an example. With the prevalence of IOS-XE in the enterprise network I would love to see both the IOS and IOS-XE example. Or the IOS example shown and the IOS-XE example verbally mentioned. To my knowledge there is no 'show run linenum' in IOS-XE.
Thank you. Did you try it on XE? Here is my test on a CSR and it works: Router# sh ver | include IOS_XE Cisco IOS XE Software, Version 16.06.01 Router# sh run linenum Building configuration...

Thanks alot Mr David again great video I have learnt something new.and I enrolled 2 courses Im gonna look into it.i knew i will learn something from those courses 😍👍👍👍
Excellent! regex is definitely a powerful tool. Thank you for sharing such a great list of time saving and interesting commands. I really appreciate it! And of course, appreciate the giveaways ;-) too. Until next time.
@@davidbombal By the way I tried running the GNS3 VM with VMware player 15.x and VIX 17.x API dependency. However, I got an error at the time of loading it. I believe is because the version of GNS3 needs to match with the version of the GNS3 VM. I tested this in the latest GNS3 2.2.0rc5 the GNS3 VM is 2.2.0 perhaps that is why... I will test this weekend with the version 2.x.x stable GNS3.
Really glad you learned something new. My goal is to teach you stuff that they don't show in standard classes. Amaze those around you with your knowledge :)
I have learn a lot in this one. "Show run all" made me say "holy crow"! Was hopping to get the python for free but bad luck. anyways Thank you for making us (Network Engineers) great again.
Dear Mr.Devid , i am facing issue while start capturing between node and client PC by using Wireshark, can you explain to me if there any specific configuration needed
As always; learned something new again. 1 question, I learned/experienced that when using revert timer command instead of reload commandthere is no impact on the device and the network. Can you expent your thoughts about this 2 command as in the pros and cons?
I prefer using the archive command over the reload in command. By using the archive command you can create a configuration snapshot and then set the terminal timer to reset the config to the old config if no terminal input is seen in say 15 mins. This way you dont need to bring down a router if you lock yourself out. Check out this blog from my coworker on how to do this: www.lookingpoint.com/blog/cisco-configuration-rollback
New subscriber so I'm still working through your videos. Been studying for the CCIE and I've started using some of these filtering commands to get faster in the CLI.
David, my ccna RS is going to expired on June 4 2022. Can I just take CCIE security SCOR 350-701 on June 3, 2022 to maintain my status? I know you mentioned it before, but it is really complicated to understand with so much information. Plus, at that moment, am I a CCIE or CCNP?
According to Cisco you need to Pass one technology core exam and pass any one professional concentration exam. (This is also a CCNP certification if done in the same track.) See the requirements here on Cisco's website: www.cisco.com/c/en/us/training-events/training-certifications/recertification-policy.html

Thank you for the support Murat!
this is the kind of video lesson you watch over and over again. Its so useful. Great job sir.
Thank you!
Once again, another great video! 20 years as a network engineer. Never got a certification. Your videos convinced me.
Wow! Really happy to hear that Tommy.
Hello David. Just swinging by to say thank you for your CCNA courses. With your help, I passed ICND2 this morning!
Congratulations Ron! Fantastic news! Really happy to hear that my CCNA courses helped you. But, you did the work. So well done!

Glad it was worth your time watching :)
David..you’re the best! How I wish I could meet you in person.. such a great educational video you put here...never knew cisco ios can do such thing. Thanks David!

Don't give up Nathan! Use the course to practice and then go and get your CCNA!
I had no idea you could use regular expressions in IOS. I can see the usefulness of this. Thanks so much for stretching my skills.
Glad you learned something from the video Jimmy!
You are giving packet life to many of the network engineers all over the 🌎 ....
Oh dang. Again I am immediately brought something I did not know. I didnt know about the include feature after the pipe. Super helpful.
lol... that is fantastic Steven! Glad you learned something new :)
The Cisco IOS is such a powerful tool and so much fun to play around with! Didn't know these commands existed. Thanks again for such a great video!
Thank you for watching Dean. Agreed - so many options in the Cisco IOS!
I learn something with every video you put out! Thanks, David!
Really glad to hear that Jason!

very informative video.
I have Udemy courses by you! Thank you David
Please please please another video about regular expressions will be cool. and thanks!
Will add this to the list :)
Sir, These shortcuts are applicable after you have gone through all the IOS commands. We are not there yet and they require a live example.

Dear Mr.Devid , i am facing issue while start capturing between node and client PC by using Wireshark, can you explain to me if there any specific configuration needed
Any show command to check if reload is active on Cisco device
i like the cmd show run | include = its a life saving
Glad you found a cool command in the video :)
Yeaa love the cmd inc expression.. its really help when u find some config and do some troubleshoot.. thx for ur info.. really helps. 😊
