In this video we will go over Etherchannel.
Etherchannel is a feature used to group multiple parallel links into one single logical interface. This is great for STP redundancy because STP will only need to reconverge if all links within the Etherchannel fails. It also provides load balancing.
Configuration Options
On/On - This will statically set the Etherchannel
Desirable / Desirable - Will create a PAgP Etherchannel
Desirable/Auto - Will create a PAgP Etherchannel
Active / Active - Will create a LACP Etherchannel
Active / Passive - Will create a LACP Etherchannel
Show Commands
show spanning-tree VLAN VLAN Number
show etherchannel summary
show interfaces port-channel Interface Number

My goodness...how easy was that. Good job because what you did in 11 minutes I couldn't understand in 1 hour of reading!

[@Certbros]

Thanks Edward. Glad to liked the video.

[@dusshan1]

yeah.. i mean i hate Wendel odom's 800 page long books in a way that cant be described using polite words :)...

[@awesomebrotherhood7698]

this has helped you to undertsand because you have done previous 1 hour, which has set some prime knowledge already. Keep up the reading along side these, reading gives more indept understanding.

[@chrispainter3602]

Yeah i totally agree, you can't teach someone a topic using terminology from deeper knowledge of the subject. Teachers forget this too much!, Not CertBros!

[@chrisfoster3772]

Hey Edward! Thanks for the good words, stoked you like the content! Remember to smash that subscribe button and hit that bell while you're at it so you get notifications for new content! God bless!

Thanks Wiliam!

Lovely way of teaching Etherchannel . Precise, subtle and efficient
I could not learn better than this. Thank you CertBros

Keep it up! Don't stop the videos

[@Certbros]

No stopping! Thanks for the comment

[@aidanluby]

One thing I'd add is once the port channel is up, if you need to make configuration changes don't do them on just a single physical interface at a time or the port channel will come down due to things not matching. Instead make changes on the logical port channel interface and the Cisco device will automatically copy those changes to the physical interface configurations so that you don't take the whole interface down.

[@vladislavkaras491]

Thanks for the tips!
Quick question:
Is it possible, that only 1 side uses EtherChannel, thus it would lead to strange problems?

[@MagnumCarta]

Good video and good explanation of LACP from the switch side. I work on rack servers and dealt with an issue of a port-channel being down that was causing unreachability issues for a server. We aren't sure what caused the configuration to go down but once we determined the issue was on the switch side and not the host side, we got the networking team to fix the issue. It was boggling my mind, the on-site technician, and their manager.

[@leonardobascope6492]

Thank you very much! This was very useful!!! I would very much appreciate if you make videos about the CCNP Routing and switching content!

[@infotechyeti]

awesome explanation. thank you for not speaking so fast and taking pauses in between. helped to take notes on studying for my ccna. subscribed

[@Certbros]

Thanks Jonathan! That's great feedback 👌

[@jairusan]

CERTBROS, clear, simple, awesome! love the way you present the concepts specially when there are examples in the CLI, 2 things I would recommend 1. please use the correct names on the CLI modes so people start getting used to the correct cisco naming Exec mode, privilege Exec, Global config etc... and 2. Please a video about trunks, switch trunks. Thank you!!!!

[@Certbros]

Thanks man! Good ideas. A video on trunks and VLANs is on my to-do list!

[@Albertolopez084]

Fantastic video. Short and clear. Good job, keep it up!

Studying for my ccna 200-301 exam with virtually zero prior i.t / computer experience and even though I am passed this portion in my studies I wanted a quick refresher course to reaffirm what I had previously learned since I wanted some clarification or a general overview of the topics to jog my memory a bit so thank you very much for providing such valuable and easily understandable content for free!

PAgP -> cisco
LAC-> vender neutral.
just remember that Pag is spanish for "pay up", which makes sense that it is cisco's standard. and according to cisco, it's desirable to pay up // *desirable / desirable* OR *desirable* / auto

remember to use a crossover cable if u connect two switches or routers with another..
