You won't but I will
Switch: mikrotik CRS504-4XQ-IN ($799.99) Cabling: QSFP28 to 4 x 25G SFP28 DAC ($63.00 per cable) NICs: Intel XXV710 25GB ($349.0)
I don't know how many machines you have so for two machine it's cost you $1562.97 and maxing out the switch would cost you $6651.83 but do you really have sixteen machines that need or can even physically saturate a 25GB line?
I think it's more reasonable to get something similar to ubiquiti's USW-Pro-Aggregation and have three machines capable of the full speed and 28 machines capable of half rate speeds (at a much lower cost per machine)
What about a router?
Both switches mentioned are L3 switches meaning they are a routers too.
I have no idea how well a L3 switch would work on a residential WAN connection. But don't L3 switches lack features like NAT, DHCP, DNS, Firewall, port forwarding, etc?
DHCP and DNS (and Firewall, but I guess you don't have a 25 Gbit/s FW) are of course easily moved elsewhere, but what about the others?
Well this is getting into the weeds a bit but TLDR it depends on the L3 switch.
For the mikrotik switch I mentioned, it runs the same RouterOS v7 as their actual routers. Anything you can do on a single purpose router you can do on the switch albeit at a slower speed for applications as the CPU in the switch isn't as good.
For the ubiquiti switch... I'm not actually sure as ubiquiti's L3 implementation is not exactly ideal (bordering on broken depending on who you ask)
Thanks!
I have only played around with L3 switches in packet tracer and iirc they missed a bunch of router features, not sure though.
Either way, packet tracer uses pretty old IOS versions and Cisco is pretty annoying so it wouldn't surprise me if they locked it down on purpose.
