Cisco Command Line Tips and Tricks

In doing some labs I ran into something I've never had to do before and I'd thought I'd share the solution with you along with some handy CLI tips.

Great video! Thank you! I’m studying for my CCNA and working as a Systems Analyst now in a Cisco shop but the studying seems to go slow for me as I’m 55 now. I love it though. Hope to have the CCNA by April. I’d like to keep going all the way to CCIE. I watch your videos and others as they provide great info and inspiration. Hope you had a happy holiday and a happy new year!

[@jeremiahwolfe]

Thanks Pete, I hope you enjoyed/are enjoying/will enjoy the winter solstice related holiday of your choosing. ;) Good luck on the CCNA! I feel you, man. At 45 my brain is not quite where it was 20 years ago. Stay tuned, I'm planning on taking the CCIE EI lab in late Spring, early Summer. Once I finish I will be putting out some videos with a complete study plan including costs. I've wasted a TON of time and money working on my CCIE and I'd like to save others from my mistakes.

thanks mate, I didnt know any of that information. appreciated

[@MultiL07]

Thank you for these very informative videos. I was wondering which SSH client you use. The colors make the explanations much clearer and easier to understand.

[@jeremiahwolfe]

SecureCRT. It doesn't do the highlighting by default, you need to load a Keyword file. Just Google it. I'm pretty sure you can also do keyword highlighting in Putty.

Great tips thanks for sharing

[@billittoG]

hi guys please help, do we use tab or enter the command?

[@papabear7875]

Nice video! When you get a chance can you do a video for SecCRT termianl color scheme? Thanks

[@jeremiahwolfe]

No need for a video. A quick google search should do it.

[@papabear7875]

Resloved. :) @@jeremiahwolfe

[@onlyhehe2k10]

hey thanks for the tips. what is ssh client?

[@jeremiahwolfe]

Secure CRT

[@haoruan4928]

how about "include is up|Internet address|Secondary address"

Hey Brother, thanks for another great video. Could you please share your opinion on AI, it's becoming a media frenzy. Just watched another vid where ChatGPT literary creates a Cisco router config from scratch replying to a user's request . Thanks and happy New Year.

[@jeremiahwolfe]

Hello E S, ChatGPT doesn't really change any of the opinions I've shared in my previous AI videos. ChatGPT is pretty remarkable, but mostly in its ability to package information, less so in its ability to process information. While there are some Wow! examples out there, there are also many facepalm failures on the part of ChatGPT. Regardless, in my opinion... (for what that's worth)... we are going to see a hollowing out of IT in general and networking specifically. That is to say there will still be plenty of CCNA type, jobs. Taking calls, working tickets, reporting issues to carriers, etc. For the time being there are just too many disparate moving parts for AI to handle that role. (Take a step back from the hype and look at your smart assistant. Smart assistants have been around for what?... 8 - 10 years. They can still only handle the most rudimentary tasks that fit within a well structured and highly constrained system.) It's the mid-tier jobs that are really going to take a hit. The CCNP level jobs. Today, right now, with tools like DNAC and vManage you can configure an entire network by selecting the right checkboxes (that's an exaggeration, but not much). So the people who know how to configure moderately complex network will no longer be needed. One engineer can do the job of 5, 10 or maybe even 20 engineers. And that's today! It's only going to get better. There will also be jobs for the senior level engineers (though I don't know how one will transition from tier-1 to tier-4 then there's nothing in between). These senior folks will do the design (or tweak the AI designs) and handle the more complex configuration and troubleshooting. I guess eventually even those roles will be replaced, but I suspect it will be a while.

@@jeremiahwolfe thanks, that's exactly what I was thinking. I lost all my excitement about IT....

[@matthewwitherford]

Good tips, keep doing videos like these, be interesting to see some videos of you doing some of your labs maybe just short guides. They do say that teaching others also provides very good memory reinforcement as well.

[@jeremiahwolfe]

Hello Matthew. Perhaps after I complete the CCIE I'll make some lab videos, but since I'm using labs sold by other's, it would be unethical of me to share their hard work for free. But yeah, I've thought about doing labs. It won't be till next summer at the earliest.

[@Frissdas1207]

​@@jeremiahwolfe would you be willing to share who's courses you bought? Im interested in content you recommend. You've been doing IT longer than me, by a lot. I like your videos and you seem very competent in networking.

[@AndreiCCIE]

Top notch videos. As always. Could you please tell me if the colors in scrt are default in scrt options tab or is something custom made by you?

[@jeremiahwolfe]

That is a function of SecurCRT that requires an INI file. Just Google: securecrt cisco keyword highlighting Or follow this link: forums.vandyke.com/showthread.php?p=49910

[@allans.9754]

Dear Jeremiah! I knew your voice was familiar. Wow! I didn't know you had become a Cisco specialist. What a joy it is to have your voice teach cisco commands. From the moment, I heard your voice, I knew exactly who you were! What a small world! Thanks for sharing this video.

[@andreas33693]

I subbed just for seeing this video.Keep up the good work. Thank you

[@PrimephotoStudio]

Nice job on the video, very helpful. Thank you for sharing it.

[@MrWinfil]

I liked these tips. Keep doing like this video. Thank you

[@joerockhead7246]

I like this in a lab envrionment: no ip domain lookup line vty 0 4 privilege level 15 logging synchronous no login transport input all It allows me to jump from box to box quickly without having to login as long as I have IP connectivity. Love the videos. Happy New Year!

[@jeremiahwolfe]

Thanks! In EVE you're on the console port, so this wouldn't necessarily apply in that circumstance, but certainly helpful for other situations.

[@ArashAlbandi-wu9mv]

This should cover all the interfaces/IPs (don't forget your Tunnel interfaces ;): sh ip int | i Inter|Secon|line

[@jeremiahwolfe]

That does show all the interfaces. In the video I was specifically trying to filter out down or unassigned interfaces (as the output can be hard to read with them in there). So you commands doesn't accomplish what I was looking for, but it does show secondary addresses and subnetmasks.

[@gossimaka]

Great Video as always. I'd rather replace the "no ip domain lookup" command with "transport preferred none". This way you keep name resolution on and get rid of those annoying delays when you mistype a command. This said, I'd love to see more videos about your study strategy and techniques to increase focus and remember stuff. Thanks and happy new year

[@jeremiahwolfe]

Good point!
