layer 2 switches work by mac table(data link layer) layer 3 switches work by ip addresses(data link & network layers) in that case why they still produce layer 2 switches? is there any specific need for producing layer 2 switch?or maybe its because layer 2 switch is cost efficient?can routrer do switching vice versa?
That is a good question 😬. There are two main reasons 1.cost Layer 3 switch will cost way more than layer 2. 2. Requirement Such as if you need just switching on your network or if your network is very small . Then is there is no point going for l3 switch which will have more complications than l2 Routers are pure l3 devices and I guess will cost more than l3 switch. Yes in some router you will see 2-4 Ethernet ports you can add and which can do switching
Can I use a one L3 switch to create 3 VLANs and do inter-LAN routing, without having to use a L2 switch? i'm trying to figure out the capabilities difference between the L3 switch and a router.
I just got a L3 Cisco 3850 and am at a bit of a loss how to implement it in my home network. Do I have to buy the network module to plug into my router? Will plugging a L3nswitch 8jtona wireless router make a ton of problems?
@@networkingwithh4716 WS-C3850-24P- EV06. Thanks for replying. It doesnt have any sfp net modules, but I was trying to figure out if I could use it to replace my home router and have it do NAT, QOS, DHCP , as routers do. It's starting to sound like NO. But I thought I'd seek others' knowledge. Thanks for responding
Good explanation bro thanks Could u help me to choose the best layer 3 for the core and the distribution and layer 2 switch for the access For my new network In the core I need low than 14 ports layer 3 switch And distribution more than 14 port And the access 24 port
Depends on your budget as well... For core and distribution check below link www.cisco.com/c/en_ae/products/switches/product-listing.html#CampusLANSwitches-CoreandDistribution For access check below link www.cisco.com/c/en_ae/products/switches/product-listing.html#CampusLANSwitches-Access
Yeah, I was also confused as to whether it's at L2 or L3 switches where you create the VLANs. Do I need both for Inter-LAN routing? If I already have a L2 switch with multiple VLANs, why not use a router instead of L3 switch for inter-Lan routing?
Cool..but the L logical link control was missing to explain..LLC provides multiplexing mechanism that enables several network protocol to coexist to be transported over the same network medium...and also provide flow control and automatic repeat request ARQ. ( although modern switches do not operate it..because this feature is now present at the transportation layer (TCP)...Also the MAC layer CSMA/CD carrier sense multiple access with collision detection was not mentioned...which synchronizes,detect data collisions working in the frame transmission...nowadays is a deprecated technology..but it is worth mentioning...modern ethernet network no longer need to use it because each collision domain is now isolated...
Great content but still would like to share feedback if you take it in a professional way. :) Often times you finished your sentences quickly, it's all good for Indians to understand but you have a world level audience so maybe you can go a little smooth on that part. Due to the quick finish, you ended up correcting yourself more than ones and hence you can work on it if you like. Just saw one typo but shouldn't be a problem. All and all, you have a very good presentation style and just need a touchup on the final content. All the best and looking forward to more videos.

Your effort is appreciable . You really deserve my like and share .
Thank you so much 😀
Thank You for the simple wonderful and to the point explaination.
Surprisingly Good Presentation ! Excellent clarification and very informative , I like your style .
Glad you liked it!
Thank you that was nice, and recovering from covid, keeps me informed and not losing pertinent information for my network plus
Your efforts are excellent
Share another video step by step.
Best explanation.
Sure 👍... thanks :)
Very good - I liked the presentation - clear and simple - thank you
Glad it was helpful!
Nice your explanation is very simple and understandable.
Thanks for liking
Helping vedioo . Can you suggest me which switch is best for distributions to other switch...?
Are you planning to replace old switch in existing network or is it a new network? Can you share more details please
Very informative video, thanks

That is a good question 😬.
There are two main reasons
1.cost
Layer 3 switch will cost way more than layer 2.
2. Requirement
Such as if you need just switching on your network or if your network is very small . Then is there is no point going for l3 switch which will have more complications than l2
Routers are pure l3 devices and I guess will cost more than l3 switch. Yes in some router you will see 2-4 Ethernet ports you can add and which can do switching
Nice video I appreciate it , short but full of details
Glad you liked it
Great video. Thanks for making and sharing
You are most welcome 🙏🏻

yes you can create 3 vlans and do intervlan routing on l3 SWITCH...

Hi, Does L3 switch need a router to create a vlan?
Yeah, I was also confused as to whether it's at L2 or L3 switches where you create the VLANs. Do I need both for Inter-LAN routing? If I already have a L2 switch with multiple VLANs, why not use a router instead of L3 switch for inter-Lan routing?

What about PC C? Why cant it reply back?
cool thanks
Thank you too
Sir. You are speaking too fast. Slow down so people can understand you.
Very terrific accent! I give up
Thank you
