i am attempting to setup the 6450-48p, and using fohdeesha tutorial. i am using the included tftp application, yet keep getting an error that says, "recount try exceeded. please try again." can anyone tell me where i should start troubleshooting for this issue? my firewall is turned off, and antivirius is temporarily disabled.
"Recount try exceeded" means the switch is not establishing a connection to the TFTP application. It keeps trying to connect, and eventually will fail with that error message.

You need to double check that your switch and you computer are on the same network segment. Also, make sure the TFTP app is set to use the correct network connection (the one with the IP address in the switch's network segment).

Also triple check that you are following the guide exactly. It is easy to inadvertently skip a "small" step/detail that ends up being the entire reason why something isn't working or connecting.

i now see my switch has an IP of something like 164.x.x.x and my computer is on 192.168.1.x since the switch is not fully operable, i guess i need to change my computer to an IP on the same range as the switch? is that correct to start with? my tftp server is set to 192.168.1.x

You need to change the IP address of either the computer/tftp server or the switch. It really doesn't matter which one. Did you assign the switch an IP address? It's one of the first things the guide has you do.

ah, i forgot i did give the swtch a temporary IP of 192.168.1.29 in one of the steps. that means the switch, and laptop, and tftp sever software all have 192.168.1.x IP's. i am thoroughly confused as to why it wont work. maybe i should take a screen recording, or screenshots and post them. hopefully a simple step i am overlooking.

I can only suggest that you read through the guide once again and make sure you read every line/word carefully. It's easy to let your eyes skip over a step thinking "I've already done that", but if you are methodical in your review, it is likely you will find a step that you missed. It could be as simple as having the network cable plugged into the wrong port on the switch (management port or regular switch port when it's suppose to the the reverse).

PS - reading through the guide myself again just now, I realized it's not the initial IP address that you assigned to the switch that matters for the tftp server. It's the address that you assigned to the VE 1 interface and the computer's network address that need to be in the same network subnet. That way when you connect the computer directly to one of the switch's regular switch ports, everything is in the same subnet.

thank you. i was just reviewing the instructions again, as you mentioned. i was only using my console cable. i think the instructions said an ethernet cable is also needed for the managerial port to connect the switch to my network. if that is the case, my lack of paying attention would be to blame.

Yes. You'll definitely need an ethernet cable in addition to the USB console cable. You'll start with the network cable plugged into the management port, but will quickly end up moving it to a regular network port on the switch when directed to in the guide.

Long story short, the commands you enter into the CLI are via the USB console cable, but the data transfers from the tftp server happen over the network cable.

Quick question: How locked down are ICX 7750-48F switches? I might be able to get one cheap. The only hold up for me is no POE, but I technically only need one POE port at this time and I could use an injector.

not locked down at all using the honor licenses here - ICX7xxx Licensing - Fohdeesha Docs

only thing is they are very old (still powerPC based, not even ARM), and oold gen broadcom, so they suck power. I would get an arista instead - 48 ort 10gb aristas are like 200 bucks ish on ebay

I found a youtube video last night on this. Thanks for the link to the exact info.

So I need/want at least 24 ports of 1/10Gbe. 48 ports would be very nice and a bit more future proof. I also want 6 ports of 40Gbe. Two to connect to my ICX 6610 in the garage and four to give one each for a four node Proxmox cluster.

Any Arista switches you could recommend that meets this? Usual nice to haves: 1) power consumption (Thanks for the heads up on the 7750!), 2) noise (I've been perfectly happy with the ICX 6610.... AFTER I added a pair of 120mm fans to it's lid to keep it from jumping to full speed every few minutes) and 3) Ability to use a wide range of SFP+ and QSFP+ transceivers.

Thanks for the help. And thanks for kicking off this thread to begin with. It has been VERY helpful!

I like my DCS-7050QX-32S well enough; it's all QSFP ports but the first 24 (? not at home and can't check exact number)) ports support 4x 10G breakout. So I have FS.com QSFP optics in them going to 4x LC pair breakouts to a patch panel with LC-LC couplers.

Since you say 10 Gbe I assume you want copper, which would mean a 7050TX-72Q based on this: https://www.arista.com/assets/data/pdf/Datasheets/7050TX-128_48_Datasheet.pdf

The Aristas do not have PoE unless you look at the relatively new (and therefore expensive) 720XP series.

Maybe you're referring to GbE-T? Regardless if twisted pair (copper) or fiber the switch is passing ethernet.

The 7750 has the exact same ASIC as the Arista 7050TX-72Q.. Both use Broadcom Trident 2.

If you want 6x QSFP and 1/10G RJ45, 7050TX-72Q is your way to go. 7050TX-72Q needs about 170W in IDLE (no ports connected), the 7750 needs less if I remember correctly. I'm currently selling my 7750-48F

Maybe similar to whenever I see the Futurama quote you wrote I always think of Tintin's Thompson and Thomson's "to be precise."

pretty sure @clcorbin was looking for an SFP+ switch, as he originally said he was getting an ICX 7750-48F, which is the SFP+ model. for an SFP model (not copper) you can do a lot better power draw wise than the 7050TX-72Q @NablaSquaredG mentioned (he was assuming you wanted 10gbe copper)

I'm currently getting rid of my 7150-24P. The reason is: If I use a 24 port switch (and not a 48 port one), power consumption matters. So using a switch that uses ~45% more power doesn't make sense.
If you need the 4 more SFP ports or some newer firmware feature (like management with SmartZone or Unleashed), go for the ICX7250-24P
I think you meant the 7250-24p and not the 7150-24p. I did a lot of research and came to the conclusion to buy a 7150-24p. I got a good offer and bought it.

The 7150-24p needs ~30W in idle with only one uplink which is 5W(~15%) less then the 6450-24p. So I'm almost satisfied now, only I have to change the fans because they are too loud to run in the office rack.

My girlfriend tears my head off when she has to work with the noise. But I have already ordered Noctua NF-A4x20 4-PIN.

btw. thank you @fohdeesha for this thread and your guides.
