Current Events > Quick networking question - packet tracer

(+) Yeah! (+)

I'm trying to connect 24 computers on one subnet. The switch doesn't have enough ports, can I add another switch to split a port? If not, what should I do? Here's a picture, bottom subnet isn't getting an IP from DHCP:

@CableZL would know but i believe yes

I tried cutting off the other switches and just hooking up one PC to Switch3, but still failed. So must be some config issue I did the same for all the other subnets and it worked :(

I had 198.168 on that port from the router instead of 192.168!

i have barely ever used packet tracer and know almost nothing about networking. but could you not plug a switch into another switch

It just says "Switch-PT", which I think stands for Packet Tracer. They have 10 modular slots for ports, actually only start with 4 ethernet ports.

Sorry, I think I made the OP confusing because I was in a rush. The subnet where I plugged switches into another switch was the one that was broken. The class never actually taught about that. I also connected a switch to an AP for the first time. This was all part of the final (don't snitch)...
I got it all working in the end and it came out pretty nice. Hope they don't knock points for random BS, the requirements were pretty vague.

/27
5 needed subnets, biggest one has 26 hosts. I'd post the prompt but honestly scared it might show up on google or something.

Oh, that's smart. Thanks, I definitely did not know that. I ended up adding a printer to every subnet and a laptop to 192.168.1.1, so I guess I should've done:
Net - hosts - broadcast
192.168.1.0 - 192.168.1.1/29 - 192.168.1.7
192.168.1.8 - 192.168.1.9/29 - 192.168.1.15
192.168.1.16 - 192.168.1.17/29 - 192.168.1.23
192.168.1.32 - 192.168.1.33/28 - 192.168.1.47
192.168.1.64 - 192.168.1.65/27 - 192.168.1.95

Network - broadcast
192.168.1.0 - 192.168.1.3
192.168.1.32 - 192.168.1.35
192.168.1.64 - 192.168.1.71
192.168.1.96 - 192.168.1.103 (I think you need to do /28 for 8 PC's + gateway)
192.168.1.128 - 192.168.1.159

I was stuck doing
config t
ip dhcp pool Richard
net 192.168.1.0 255.255.255.224
default 192.168.1.1
exit
ip dhcp exc 192.168.1.1
exit
>repeat for each subnet. Is that how you do it IRL? Feels like it could be a small bash script.

Cool, thanks. This was my first networking class in 14 years, off and on, of various college work. Literally "Intro to Internet Networking." The beginning was really rough with a very bad explanation of the OSI model. I still can't memorize port numbers, the network management stuff just made my eyes glaze over (SNMP, couldn't test it on Packet Tracer), and I never got a good example of NATs. But the networking labs were really fun and it was cool setting them up and making them work.

Good job finding the solution!

It took me a bit of practice to memorize some of the commonly used port numbers. In the real world, you don't really have to memorize most of them, but you'll want to know some off the top of your head to speed things along.

I can also share some videos with you that might give better explanations on some things if you'd like.

Cool. I'll watch any videos you send me, eventually...

I'm kind of at an impasse in my life right now. Can either decide to get A+, Network+, and look for an IT gig in less than a month - or pay around $40k to keep doing ASU online or $80k to go in person.
If I keep doing ASU, my next classes are Active Directory and Cybersecurity But the semester after would be Network Technology.

I'd day go for the sector of IT that interests you the most. As miserable as I was after doing ISP tech support for 5 and a half years, I did use those two jobs as a way to find out that networking was the area of IT that interested me the most.

I'm probably not the best person to give advice on whether you should continue your college education or not. I dropped out of college after 1 year for a few different reasons. I didn't have any sort of career plan or actual idea is what I wanted to do for a living at the time. In hindsight, I wish I had paid more attention to the fact that computer networking was my favorite class in high school instead of aimlessly going to college just because my mom and my teachers said I should.

I'm not sure if that would have given me an interest in finishing school, but I think I at least would have had an actual interest in being there. Instead, I just tried to major in computer science, but took random "prerequisite" courses that had nothing to do with computers. I was bored out of my mind and was dealing with health issues and the high cost of tuition at the same time.

I didn't start in IT until about 3 years later,and those were some rough years hopping from job to job to job just hoping to find something that was better.
