CISCO Port Security at work | Commands and tutorial for beginners (Packet Tracer)

[@ahmedezz_]

I completed CCNA 6 months ago and Now I am refreshing my information. Keep it up, you are so helpful !!

[@EastCharmer]

You're welcome!! Nice! Just keep practicing too with labs. I've been practicing too so I won't forget

[@avimehenwal]

Very informative and really good stuff ... keep it up

[@EastCharmer]

Thank you!! Much appreciated!

[@Wawgrp]

I like the way you do it. More action than words. Keep up the great work.

[@EastCharmer]

Thank you! I actually thought I'm talking too much

[@crowncontrol3637]

Great video. When you entered the "shut" and "no shut" command, did you have to select the port? I might have missed that part of the tutorial. I'm guessing you had it already selected by that point but you issued the show port security command followed by the "shut" and "no shut" command(around 19:40) minute marker. Thanks!

[@EastCharmer]

yes! You have to be on that port interface to do the shut/no shut command. For example: switch1(config)#int fa0/1 then switch(config-if)#shut

[@duafox1600]

I love your networking series. Thank you so much. Your networking playlist is really helpful.

[@EastCharmer]

Happy to hear that! you're very welcome! And I hope I can keep posting videos like this

[@faroufakmdps]

Each video comes with new information. I love those hand on security videos. Please make more.

[@EastCharmer]

Will try to make more!!

[@faroufakmdps]

@@EastCharmer Finger crossed. I am waiting my friend

[@lubpaj91]

Amazing job! I love how you indicate the show commands and config commands for each configuration. It helps a lot. Thanks and keep it up.

[@EastCharmer]

Thank you! Yes, show commands are important to know and verification should always be a part of the configuration as well.

[@Web_king65]

for me I learned a lot of things that I didn't know before so you're helpful

[@EastCharmer]

I'm really happy that you did!

Another great content ate! Keep it up po i love to see this kind of tutorials, showing the actual and real scenarios of what's happening inside IT. An addition to one of my favorite channels in YT aside from Networkchuck.

[@EastCharmer]

Thank you so much 🤗 I've been watching Network Chuck too!

[@espnmk]

thank you so much for your tutorials, i'm definitely going to rewatch this series all over again for the knowledge.

Welcome aboard! Thank you so much!!

[@elhagea]

Great stuff as always. Almost starting to forget all this after being out of work for a while. Keep up the good work.

[@EastCharmer]

Thank you! Oh yeah I forget too especially if I don't practice with it that often. So making these videos also is a refresher for me

[@locumania]

Yay ! My fav IT Channe! Thanks for educating us.

[@EastCharmer]

So flattered! you're very welcome!!! home to make more videos like this

[@zainuddinbrahim4625]

i use to go for the actual switches and routers configuration course too but this is also part of my refresh too, thank you.

[@EastCharmer]

That's nice!!! Also a reason why I make videos is to refresh and motivate mw

[@ozkand.2666]

Hello, Thanks for your informative videos. After the pandemic, many companies switched to a hybrid work environment. Within the scope of the smart office work environment, different users can sit at a table due to the hotdesk seating arrangement. What kind of structure would you recommend to establish in such an environment? Thanks in advance.

[@EastCharmer]

Hello there! Ah yeah the Hybrid environment is tricky to setup. Ok for hotdesk, I would recommend using Thin Clients because they're easier to manage with just the programs that the users need especially if they're using mostly web-based systems. You can just setup up a browser and everyone can use them. Easier for IT to maintain coz it's locked down to what they need

[@brightstar6957]

Great! One of the best Networking KZbinr.

[@jeanphilippeHamon]

Hi, Thanks for your work about Cisco configuration. I use for my job port-security, as you said, to protect unknown computers. But I’m looking for command who shut port for a little time because it’s a wrong mac@, and when the right PC is connected port is in normal state, so up. If you have any ideas ? Thanks and best regards

[@sukhminderpal2465]

Configure the # Err-disable recovery cause port-security (By default it will reset your port after 5 minutes) or you can manipulate the time as well

[@EastCharmer]

@@sukhminderpal2465 thank you! I just remembered this one.

[@jeanphilippeHamon]

@@sukhminderpal2465 hi, thanks for this command. I will try this tomorrow. Best regards and have a nice day

[@jeanphilippeHamon]

@@sukhminderpal2465 thanks for sharing this command, after reading about this, I do that : errdisable recovery cause psecure-violation errdisable recovery interval 30 . This command works well. My mistake was to looking and searching the same command for a port. All switches ports are protected and it’s better. Thanks for your help, have a great day. Best regards.

[@bnrid8086]

can you made tutorial how to create vlan interface on cisco router?

[@EastCharmer]

ok I'll try!

[@stefanomaggiore15]

​@@EastCharmer what do you think about IPv6? Was the need to replace IPv4 necessary given that PAT is used and the addresses are enough anyway?

[@Leokev123]

do you have video on AAA (Radius & Tacacs+)? Love you video btw!

[@EastCharmer]

Thank you! I don't have a video on that yet but that's a great video idea!

[@sageadams9903]

sorry to even ask this Q? do you see the layoffs in your arena of IT? Or do you find being a (hands on) technician/engineer/what you do VS sales, management and outliers being non tech layoffs. i dont see anyone really talking about it. Thank you

[@EastCharmer]

no that's a great question. hhhmmm well I think I can only speak based on my experience and on what I've observed so far since the pandemic. I think IT is solid when it terms of layoffs (tho this might not be the case to all IT jobs). My previous company laid off around 50% and no one from the main IT team was laid off. I think this is because IT runs the infrastructure and systems so if they lay off IT, who's gonna run the tech and who's gonna offboard the people? Also from what I've seen, IT is more stable and safe even if the job isn't always exciting compared to the more popular tech jobs like cybersecurity, software engineers etc coz those were the jobs that were laid off from my company. But this is all just from my experience

Thanks!!!

[@MeZzZzZzZzZzZzZzZzZ]

Very useful. I know you have a networking playlist already but any chance you could create a ccna playlist for those going after the cert? Also id be curious about how you broke into the it world. What certs/creditials did you have to get a job?

[@EastCharmer]

Thanks! hhhmmm I'm not sure if I can make a CCNA playlist coz my CCNA knowledge is not up to date. but I might do some CISCO cert playlist if I get a cert. I studied IT in school and got my A+ and CCNA training.

[@Manu-rd4pc]

If you're looking for a complete CCNA course, i recommend this channel : @JeremysITLab, it covers any aspect of the CCNA and Jeremy is a great teacher!

[@runnerlinux1474]

Teacher, i try to follow your step then remove the cable...and join using another pc..one end to switch is red but other end to pc is showing green..dont know where i getting error

[@EastCharmer]

Hello, you have to re-enable the port where you plugged in the cable using "no shutdown" command. If you have port security on that port, it would only work on the computer with the MAC address saved on the switch

[@runnerlinux1474]

I will keep trying...it"s great to have someone like u teaching us. @@EastCharmer

[@EastCharmer]

@@runnerlinux1474 I hope you get it working! Just remember that if you set the port to shutdown, you have to manually re-enable the port

[@ThatBigDon]

I think I’m in love haha ❤

[@Abdelkader373]

Can you make a video for full router configuration plz

[@EastCharmer]

I'll try!

[@MinifigNewsguy]

What happens if you have multiple hosts in a single room? The hostname of my devices are by asset tag numbers.

[@EastCharmer]

great question! we just add letter after the room number like 1010a, 1010b, 1010c and so

[@ashwinchimankar3392]

Thank you for this informative video. Q. Ccna Cisco certification really worth it or not and is there any future scope after completing Ccna certification? Please answer.

[@EastCharmer]

you're very welcome! I think it's still valuable because CCNA also teaches you fundamentals of Networking and CISCO has been a popular brand and a lot of companies have been using it.

[@ashwinchimankar3392]

@@EastCharmer Q. Popularity of clouds storage is increasing so what is your opinion on this and still any scope of Ccna certification in future ?

[@EastCharmer]

@@ashwinchimankar3392 well that's true but not all businesses are going full on cloud or can go full on cloud. Also, the networking is also one of the backbones of cloud tech. Not so sure about the scope of CCNA in the future but don't just focus on CCNA if you are leaning on networking. Focus of learning Network fundamentals and CCNA just like any other certs expires every 3 years or so. So you still have to keep learning in the future

[@ashwinchimankar3392]

I understand, thank you for your precious time.😊

[@EastCharmer]

@@ashwinchimankar3392 you're welcome! hope it helps!

[@bulcub]

can you run 2 pc's etc on one ethernet port? like say you have 60 pc's and only a 24 port switch and attaching 2 pc's to port fa0/1?

[@EastCharmer]

yeah you can share multiple devices on a port by plugging in different devices like ethernet switch, network bridge, hub

[@bulcub]

@@EastCharmer what i mean is can fa0/1 share 3 pc's or not?

[@EastCharmer]

@@bulcub no, I don't think it's possible to directly connect multiple PCs to a single port without using additional hardware

Can you made tutorial on how to configure a firewall

Could you feature cisco nexus vxlan implementation

yay!

[@ariarivazhagan2953]

Hi, Is there any possible to protect ports with password in unmanageable switch, suppose if I want to add any pc into network it should ask credentials for assigning IP address to that pc. It's possible in unmanageable switch?

[@EastCharmer]

I don't think you can configure it on unmanaged switch

[@aselaprasanna1435]

😍

[@cricketalwys]

Is this tool free? Do we need to buy pcs and switches or it is like a virtual playground for learning?

[@EastCharmer]

Yes Packet tracer is free. It's a simulator so no need to buy hardware. But it only works for CISCO tech

[@fun-dg2ns]

plz raisecom and edgecore configuration next video miss

[@EastCharmer]

Will try!!

[@anthonyrasat6924]

I want to know if all computers in your network have administrator-locked BIOS or not? Because someone with Linux USB thumb drive can boot up any computer without user consent if there is no USB boot locking.

Can you show something more advance and fun, like set an AI SIEM in layer 2 or layer 3

I'm making videos for beginners. And also videos showing real world practices and not clout content. If you want more advanced and "fun" there's other channels for that.

[@nxtlvltrades2862]

I understand your a network person, but network security is were FW/IDs/IPS/SIEMs would be used in real world. But I get it kid
