Thread 106354686

Should I buy a used 48 port network switch?

>>106354686 (OP)
what are you use cases?

>>106354686 (OP)
No, a Ubiquiti 48 PoE is way better to manage, cheaper to use, and more modern with better switch port speeds. A used Cisco switch isn’t even useful to learning about Cisco since they ruined their business model with a “subscription only” use and if you stop paying for the subscription you can’t configure the device.

>>106354686 (OP)
What the fuck are network switches for

I've used server stuff many times cloud and local for years and call me a retard but isn't this necessary ONLY if you have hundreds of servers and need to have them interconnected or to have a tougher firewall? I've even seen some people have this while only having 3-4 servers on their racks, whats stopping them from just using a standard ethernet cable connected to the router??

>>106354709
you are a jobless neet. All modern Cisco switches have a license installed and work once it's installed. Even without a license they will do basic switching.

Ubiquiti switches are overpriced too, and I like their cameras.

>>106354718
zoom zoom!

>>106354718
in an office environment with dozens of network socket in the walls, for example.

go the fuck outside once a lifetime

do you have 12-48 networkless computers?

>>106354737
No, I was going to plug the ports into each other using patch cables and make a rube Goldberg rollercoaster for packers so I can let them have some fun before sending them out into the wild.

>>106354726
>using cisco over ubiquiti
retard detected

No, they are as loud as a vacuum cleaner, so unless you have a separate room to place them forget about it.
If you want to learn ccna, get packet tracer
If you have more then 10 ethernet devices, get a passive cooled switch

>>106354786
Just unplug the fan bro. Unless you're saturating the switch, you don't need it.

>>106354726
>ubiquiti
>overpriced
Lmao lol even. Shopify, and several other big organizations use Ubiquiti in their offices because they are cheap and aren’t jewing you on BS license fees. Cisco is the most expensive switches you can buy and they are years behind cheaper options. Boomers like you love them because they are “safe” but in reality they are shit.

Also retard, OP is buying this for his home. Does he really want a noisy fucking switch in his house? Think McFly, Think.
>>106354718
Switches are for layer 2 communication, usually used to just have your client reach a layer 3 device (router or Firewall) to go out to the internet. A layer 2 switch also is good for home use for connecting my devices within the same network and IP space. You can even make separate virtual networks called “VLANs” that you can control and disallow traffic between various networks within layer 2 domains. For example, I want my guest wireless to have its own network, my NAS to have another, and my security cameras to have its own. This can be accomplished with a switch and router or firewall

>>106354906
>Unplug a fan on a PoE switch
Lmao how many brainlets are on g?
The fans are there for a reason. Heat will make a device die super quick.

>>106354686 (OP)
buy it for the lulz

>>106354718
>whats stopping them from just using a standard ethernet cable connected to the router??
On an enterprise router or firewall you can’t have the same IP space on multiple ports. You’d essentially need to make a layer 3 interface, then make layer two physical interfaces (making it a switch). It’ll be a bad time and routers have limited ports.

>>106354718
>but isn't this necessary ONLY if you have hundreds of servers
lol what
You need a switch to plug multiple computers in the same network. The smallest switches are nearly fucking free, you use them to plug multiple devices into the same network.

>using a standard ethernet cable connected to the router
The home "router" category of device basically performs a combo role of actual router + WiFi access point + switch at the very least. The so-called "LAN" ports on your router are basically working like a switch.

Is buying Cisco in just another "no one ever lost their job buying Intel" situation?

>>106355116
No, that was 2010-2019.
Buying a Cisco anything now is retarded for any reason. Many other vendors make much better devices at much better costs and much better licensing options.
Cisco released updates in 2018 stating if you don’t pay for their support you will lose access to configuring the device you “own”. Ciscofags cope now by saying “well they just haven’t enforced it yet!!!!!”

What rooted Cisco is disgruntled former employees starting rival businesses such as Juniper and Arista - always shop around for your networking gear. Caveat Emptor

Retard.

you clearly have no idea what you're talking about. i'm running a netgear 18 port gs with 2/12 ports running POE and no fan.
you're dumb
please don't post if you don't know what you're talking about.

>>106355141
Cisco is still the industry standard for many enterprises both small and large. Brocade is the closest rival, and several thousand steps back in the stone ages is Juniper. This hasn't changed for the past 5 years.

I do network administration for a living so ask me anything.

>>106354718
I understand the basic purpose of a switch, but every time I see someone post their home server they have something like pic related. What's the deal with all the little cables just going from one port to another right next to it?

>>106354709
What are you talking about nigger?
>A used Cisco switch isn’t even useful to learning about Cisco since they ruined their business model with a “subscription only” use
Newer Catalyst switches like C1200-24T-4X and older models have a perpetual license

>>106356206
1st and 3rd from the top are patch panels. they're just connectors for other lan cables going somewhere else in the house. they just make it easy to reconfigure connections.

>>106354692
Connecting my PC to my router.

>>106356206
The real reason is that network equipment manufacturers are fucking assholes who put ports on both front and back so you have to waste even more time and money on extra cables just so you can have all your ports on the front. Everything would be much easier if they simply put all the ports on one side instead of both. This shit seriously rustles my jimmies.

No.

>>106356206
this anon is correct >>106356259
but i also don't really get why people need to link like 40 cables from every corner of the house directly back to the main switch. i have one long backbone cable and several small switches and just daisy chain as needed.

> C1200-24T-4X
You Cisco shills are retarded. 1 Gig interfaces is what you’re flexing? Lmao. Ubiquiti can get 2.5 Gig per Interface without an SFP.
Anyway. A exact comparison model from Ubiquiti is half the price of Ciscos. USW-24

>b..b..but we changed the licensing back for this specific switch!!!!!
Lmao. Don’t cry you get burned again.

L.O.Fucking.L

>>106357366

Flexing? I'm posting about licensing, not technical parameters of switches. Are you having a stroke?

>A exact comparison model from Ubiquiti is half the price of Ciscos. USW-24
Curently on Newegg, USW-24 is $263 while C1200-24T-4X is $396, so that's clearly false.
>https://www.newegg.com/ubiquiti-networks-usw-24-gbe-rj45-ports-1g-sfp-ports/p/0XP-000A-00564
>https://www.newegg.com/cisco-systems-inc-catalyst/p/0XP-003P-031U5
You also claim that it's an "exact comparison model". C1200-24T-4X has forwarding rate of 95.23mp/s while USW-24 can only handle 39mp/s. It also doesn't have 4x10Gb/s SFP ports - only 2x1Gb/s, not to mention that unlike C1200 it doesn't support PoE.

Your seething has been noted.

>>106354718
>What the fuck are network switches for
>whats stopping them from just using a standard ethernet cable connected to the router??
If your router has multiple ports, it's because it has a built-in switch
If you need to plug in more devices than your router has ports, you buy an extra switch to expand it more

>>106354718
>whats stopping them from just using a standard ethernet cable connected to the router??
Sounds like you're thinking of a router with a switch built into it, or a layer 3 switch (in the server environment).
But, yeah, there's no reason to have a 48 port switch if you only have 5 or 6 devices. It's just a waste of power and space.

>>106354709
Ubiquiti just sucks. It's a toy for wanabe network admins.

>>106354758
>I was going to plug the ports into each other using patch cables
Better hope they have detection for this or else all you'd do is make the switch non-functional.

Dumb fuck can’t even find a good deal. $225 from the manufacturer yet you would pay a 3rd party more because you’re so wise.
>b…but $396 (plus $20 shipping you left off)
That’s pretty close to $450, which makes Ubiquiti HALF THE PRICE of your shit.
>10gig SFPs for a home lab
Do you even know what those would be for? Of course not because you’re a retard.
Even if you did a 10gig SFP from Cisco is way more than any other vendor. And you’d buy a firewall or router with a 10gig to connect it to? No you dumbfuck you would not.

Certified Senior Cloud Network Engineer type shit, truly

Used C3850-12X48U mogs ubiquiti hard.
Shit is like $130 shipped and if you buy the right one it has 12 multi gig ports, so those do 2.5, 5, and 10g. Sometimes you can get one with sfp slot modules, the 2x1g 2x10g one is pretty cheap.

We in this thread don't make that decision.
Our decision was made 5 years ago when whoever bought the switch new.
People 5 years ago bought Cisco.
And now Cisco is all there is on the used market.

OP said used, why are you people all flocking to brand new models and ubiquiti stuff?
New gets price mogged hard right now, even the cheapest multi gig unmanaged China switch costs more. You're a fucking household, you don't need a new rackmount switch

>>106354718
>whats stopping them from just using a standard ethernet cable connected to the router??
they're connected to a switch, inside the router most of the time, big difference. there are router with multiple port (usually sfp) but taht's for big boys who fuck around with vlan and shit, in the modern day even that is done by manageable switches anyways...
a router could very well be one wan and one lan interface, in fact taht's the case in many dataroom/center around the world, you're used to your ISP slop and think a router has 5 rj45 port or something but that's absolutely wrong, your ISP shitbox is a router + switch + wifi ap all-in-one.

i have two C9300-24UX next to me in my homelab as we speak. it's not even remotely loud. datasheet shows 45dB/47dB maximum (fully populated with PoE devices for maximum heat generation) for both 3850 and 9300, but you cant read a datasheet. that's between a quiet library and moderate rainfall in noise level.

>The home "router" category of device basically performs a combo role of actual router + WiFi access point + switch at the very least
Home routers are usually limited in vlan capabilities and whilst might be able link aggregate 1 pair of ports, they dont offer features like virtual switches

But, my familiarity with 'home routers' is mostly a TP-link ER605 and it lacked features I needed. I ended up going with a Fortinet Fortigate 60F as a home router and I have 2 TP-Link ER605E (8 port managed) and 1 TP-Link ER605 (8 port unmanaged) switches

>>106358949
shut up fag, literally nobody asked

>>106359006
someone claimed that a home router is also a router, AP and switch but the capabilities are minimal. Maybe if he didnt say something so retarded i wouldnt have replied

>>106358949
use case for vlans?

>>106359319
Network segregation. I don't want guests access to my home servers, webpages and shares. Likewise there are chinkshit IOT devices that send strange stuff and might also probe and so they need their own vlan so they cant spy on me and report to someone

Obviously paired with strict firewall policy

>>106359006
if you can't handle the /g/, you should stay out of the oven

>>106358755
VRFs are isolated by default so stating “isolated VRFs” is retarded and redundant.
Basically any vendor, even Cisco has dashboards for VXLAN EVPN brainlet. Unless you’re truly a retard and mess with the underlay constantly. But hey, it’s your homelab.
“4800 lines of config” woo as if that’s impressive. I bet you’ve never touched ansible in your life.

>>106359637
>whats stopping them from phoning home through their own mesh network like amazon devices?
You are suggesting that a neighboring house might have the same (or similar) appliance and that they secretly know eachothers hidden broadcast SSID to transmit data to eachother? That sounds like a lot of work. The easy route would be using whatever the owner set their wifi access to and if the connection to the internet is blocked then so be it

>>106359710
amazon does exactly that

>>106359318
>Maybe if he didnt say something so retarded i wouldnt have replied
had you read the actual chain of comments, you would have realised it was a direct and simple answer to some retard asking "what is a switch & why not just connect to the router". then you came through, completely ignoring the existing conversation and just started huffing your own farts. next time pull your head out of your own ass and actually read what's written before spewing shit nobody asked about.

>>106359318
so because it only routes between 2 networks and does basic layer 2 switching it isnt a router and a switch? youre not even trying cmon

lmao ansible very impressive. did you download your little plugins from ansible-galaxy? try using proper python next time instead of bragging about abstracted network automation programming via modules. it's not impressive but i hope paramiko is treating you well.

>VRFs are isolated
VRFs are only isolated on the legs they're defined until they hit a routed convergence point. in other words they are only separate for the length of the VRF context definitions until hitting a common transit point like an adjacent provider. i'm talking about an isolated multi tenancy specifically for VRFs. isolated multi tenancy is the nomenclature for the configuration. no convergence possible due to route filtration on each VRF perimeter.

thats not what they said at all. Go read what they said (>>106355107 in case you are too lazy to find the post i quoted) and tell me where they said "it does X Y and Z but dumbed down to only the most simple features"

>>106360572
Are you seriously hung up on Anonymous not being explicit enough about home router combo being a dumbed down version of enterprise gear? And you have been kvetching about it for the past 3 hours? The purpose of that post should have been crystal clear to anyone reading - to inform, by using simple terms, someone who doesn't know the basics, not to trigger an autistic pedantic meltdown in someone who claims to know better.

My earlier recommendation still stands, Anon. Outside time will do you good.

>>106360735

inform them on what?
What possible knowledge can be attained by telling someone "The home 'router' category of device basically performs a combo role of actual router + WiFi access point + switch"

Every normie monkey is going to get a "home router" and you telling them it also does routing and switching when it either doesnt or is incredibly limited in the function isnt valuable info to anybody

>>106360836
nta but you sound severely autistic

>>106360836
>actual router
I'm going to agree with you because "actual router" doesn't mean anything.
It routes packets between networks. It's a router. The end.
>but it doesn't have some features
Not all routers have the same features. Not all switches have the same features. That's just the way everything is.
A router is a category of devices. They route packets between networks. Don't be putting other feature expectations on top of that.

Which part exactly are you referring to? Because there is a lot of optional parts in that RFC (even many of the MUST and MUST IMPLEMENT are contained within "if implementing this feature").

>>106362074
yes you have to tease out the qualifiers. I can tell you right now that SNMP and OOB are required features with no pre-qualifiers and that kills nearly all SOHO bullshit out of the gate.

Real talk, what is the point of a switch over just using your Router?

>>106362178
A lot of routers only have between 1-8 LAN ports, if you have more than that many LAN devices, what alternative is there?

Obviously if you only have a handful of LAN devices you can likely just use the switch built into your router (just like an unmanaged switch, most router's LAN ports are essentially an unmanaged switch slapped onto the side of the router).

>>106362095
Fair.
Just installing SNMP to bring my router up to standard. Most routers have at least headers for a serial port, even if it is not available on the exterior of the device, so OOB is often there.

>>106363298
That is how they are run, most of the time.
Some firmware have the ability to manage them. OpenWRT lets you set up VLANs but usually you can't give individual ports IP addresses, so they're not fully in the Layer 3 switch (aka router) territory.

>>106363353
VLANs is a layer 2 concept. it just changes broadcast domains.

>>106354709
This is the right answer OP. Everything else ITT is wrong or outdated.
Someone seriously suggested a refurbished Cisco 3850? Anyone who has worked with that line knows it’s the worst one of all Cisco switches and most unreliable. I mean it’s already been refurbished meaning it’s already been broken. You don’t need all that for a home network, plus it’s a POS.

>>106364741
i think he's implying he's from bangladesh which is why he's saying SSH would be local

>>106365411
No. VLAN by itself is purely L2. Routing between VLANs (as evidenced by the name) is L3.
If a switch supports VLANs but not L3, then you'll need a router to move traffic between VLANs.
If the switch supports L3, then it doesn't need to send inter-VLAN traffic to the router, it can forward it itself.

>>106367187
That would make sense from his ramblings about making a spine and leaf network for a home lab and flexing a 1400 lines of config as if that means anything special.

Uh, I fell for this meme and bought one. Seems to work fine? Should I be worried?

>>106368282
Considering Cisco trusted this platform the least and discontinued it in the faster time of all their other switch series, plus it’s already broke once, I’d say yes you have a lot to be worried about.

>>106368282
No, it's probably going to work just fine.

>>106354686 (OP)
you do not need that many ports

>>106369017
>>106369064
AYO WTF? I mean equivalent Ubiquiti switches are like 10x what I paid for the Cisco switch here so I sincerely doubt I'll replace it.

>>106369099
It's not about the ports. It's about sending a TCP message.

>>106357761
You use dogshit and I'm pretty sure your helpdesk. Ubiquti is fine for small business but is pretty shit for even a medium sized org. I say that as someone who uses a lot of unifi products at home. It's great for home and small business.

this is why /g/ will ALWAYS get filtered by networking

Do you actually think colloquially referring to a packet as a "message" is filtering anyone?

What will you do if you had to install 4 surveillance cameras, one at each corner of the house, and they all needed PoE?
Buy 4 new little PoE switches, using one PoE port on each?
Also, what if you needed to put your network on a UPS? Buy 5 UPSes?

>>106357537
Dunno why people shill Ubiquity and Mikrotik.
Ubiquity APs are extremely overpriced for what they offer, it's not even possible to have different BSSIDs for each band like on literally any home router, unless you buy even more overpriced Ubiquity gear to enable those basic functions.
Mikrotik can't into PoE in 2005+20, shit's hilarious.

>>106372105
>it's not even possible to have different BSSIDs for each band
Wut?

>>106372154
Read the post, carefully. Nobody claimed that the hardware is not capable, it's a software licensing limitation – only buying a separate controller unlocks that feature.

>>106372154
Also, forgot to mention: do you know which other networking hardware supports 8 BSSIDs per radio?
The Raspberry Pi. Stupid Ubiquity shit is comparable to a $35 SBC from 2015, except said SBC requires no separate controller for that.

>>106372188
Anon, you just have to run the network controller software on a local PC, you don't have to BUY anything you fucking moron. A Ubiquiti cloud key or a Ubiquiti router would ALSO be able to run the network controller so you didn't need to run the software on a local PC, but they're not in any way required.

The ONLY instance you might need to buy one of them is if you only have a table or a phone on-site.

But if you have a laptop/desktop/server, you have no excuse.

>>106372465
>table

>>106372465
>you just have to
Why is that necessary, that is the question.
We're not talking advanced features here. RADIUS, SIM-based WiFi authentication, intelligent roaming, these I would understand. But not being able to use 2 (two) BSSIDs on a 3-radio AP is what we're talking here. Plug in the cheapest Tenda or TP-Link garbage and you won't see any such limitations. Hell, you might even see better WiFi coverage!

>>106354718
If this is bait, then well done. If not, you're the dumbest faggot I've seen here in a year and you should never talk about anything IT related ever.

>>106354718
Lmao. NetworkChads, point and laugh!!!!

>>106372780
I mean, if you're that autistic you CAN SSH into the APs without the network controller and setup multiple BSSIDs there, but it's not really the way the product is intended to be used.

But clearly you're just hunting for reasons to shit on ubiquiti, not actually learn anything.

>>106372057
fair enough, i just haven't had to do any of that yet

>>106372834
>buy to learn
I've already learnt my lesson – Ubiquity equipment is overpriced garbage shilled by people who fell for their tricks.

Where can I get a 48 port ethernet board so I can make my own switch instead of buying premade?

>>106373207
>oh no, I have to install software on my computer instead of just using an app on my phone

Omada is the same way, not sure why you're acting like TP-Link is somehow any different.

>>106373221
closest you'll get to a custom switch with reasonable effort is something like a dell S3048-ON running opx/cumulus linux

>>106373448
It was a rhetorical question. You can't get around the privacy invasion and spying unless you're willing to shill out at least $10k and build your own infrastructure. Compared to a used switch for $100 it's just not McFucking worth it.

should i buy a used mellanox pcie card and a switch with qsfp

>>106373207
>$29 switch is overpriced
How poor and brown are you? Don’t answer, we already know

>>106356443
Just get a cheap 4-6 port Switch from Best Buy if you want to dick around. Unless you absolutely need 40 ports, there is no reason to go overkill for this use case.

>>106357190
>but i also don't really get why people need to link like 40 cables from every corner of the house directly back to the main switch.
They... run lines...

It's like Enterprise/businesses, Anon. They're running lines because Ethernet > Wi-fi if you care about latency in stuff and wiring the house up allows them to plug in things like a Camera or the like (computers, other network stuff) without having to run lines or get more things.

>>106354686 (OP)
100 male connectors at least.
Maybe more.

>>106374845
Yes I'm going to chain a dozen 4-port switches to get the same result as one 48-port switch at 4x prices, 10x power consumption, and 1/4th speed

>$150 : Mellanox SX6036 Infiniband 36 Port 56Gbps QSFP Switch, refurbished on amazon
what a deal; I bought mine for $600 4-5 years ago; will probably need to find "the guy" on the internet that will generate the 56gbps license*. Be warned: it sounds like a jet engine; I've been meaning to try a fan swap

>$50 x2+ : Mellanox ConnectX-3 MCX353A-FCCT Single Port 40/56Gb WSFP IB FDR Network Adapter

>2+ 56Gbps QSFP cables
these can get pricey. If your computers and switch will all live right next to/on top of each other, you can get 1-3 meter copper cables for $30-50. Otherwise, you want optical which can be hundreds of dollars but if you're thorough and/or patient, you should find sizable optical cables for $70-100. The optical cables let you hide the jet engine where you can't hear it and distribute your other machines wherever you want in your home/office if you can route the cables with big QSFP connectors.

NIC-to-NIC direct attach is limited to 40Gbps

>a dozen 4-port switches ... 10x power consumption
Mmm, I think a 48 port switch would likely consume more power than a dozen 4-port switches.
Obviously, though, you would bottleneck devices down the line. Suitable switches depend on your network structure, not on getting the maximum expandability or value to feature proposition.

>>106374871
