I have a 7050QX-32S arriving shortly and I'll be using it with Mellanox CX3 Pro cards (HPE branded CX354) and FS.com DACs. Prettyu sure I've seen that combo before.What kind of NICs are you guys using with those Aristas?
upgrade to 4.18.x or later and thenCan anyone point me to a specific firmware which will allow third-party transceivers to be used on the DCS-7050QX-32-F ? Specifically, I'm running 4.14.16M which seems to let me use Cisco 10 GbE SFP+ optics with Mellanox converters, but not anything else third-party. I've tried SR4 modules from Juniper and LR4 (my preference) from JDSU and Kaiam with no luck.
I already have the 'touch /mnt/flash/enable3px' hack, and even 'no errdisable recovery cause xcvr-unsupported' but none of the above have solved my issues with 3rd party QSFP optics. Any ideas?
What're the file hashes ... in case I come across it lying about somewhere?I've got a bunch getting ready for production, running EOS-4.27.0F.swi. So far no problems, but haven't put them live yet.
Have not tried the firmware hacks. About four years back, FS.com specifically said Mellanox DACs would not work inside the Arista. They custom made DAC cables with Arista on one end and Mellannox on the other. When I get the ends mixed up, it does not work. When plugged-in correctly, they work great. I would like the flexibility and tininess of fiber optics.What kind of DAC cable? 10G, 25G, etc? I'm not sure what @pjackson issue was. I think DACs are different from SFPs and they might need to be Arista coded. My assumption is if you get those ones from Fiberstore you should be ok. FS is pretty good about RMAing if they don't work but you'll just be out of your time. If you have the "service unsupported-transceiver" command you should be set also but that may not apply to DACs because of how DACs work.
Also it could be as simple as pjackson plugged the DACs in before he issued that command, in which case you just need to re-insert.
That is opposite of my experience, but that is about 4 years ago.FS-coded QSFP28 DACs work fine. At least, I'm pretty sure we got FS-coded DACs, trying to confirm that now. The switches are picky about non-Arista optical modules, but I think DACs are fine. The ones from Mellanox definitely work fine.
Fodeesha, even if one found a compatible SFP+ module, the Arista would definitely not work with it at 2.5Gps or 5Gps? Hoping an Aquantia ( purchased by Marvell in 2019) based SFP+ would work some magic .... hoping! It is now a "Marvell AQS-107/CX" Sad, because MultiGigaBit can be traced back to IEEE 802 almost twenty years ago. Literally, clearly stated on slide 8 2.5Gbps is completely doable even over plain Cat5 in the "What data rates are feasible on 100m Cat5, Cat5e and Cat6 cables".nope, way too old
I have successfully deployed EOS-4.24.11M on 7050QX-32 (2GB flash variant with 2GB EOS file. i beleive that is the last supported version for 2gb flash capacityHi,
Does anyone know what is the latest version that can be used in the DCS-7050QX-32?
can you share the link to these notes, i am having a 7050-QX-32 and experiencing wierd behaviours
- Could run 2GB images but found some notes that it might produce unexpected behaviour.
You can download the vEOS lab files, but actual EOS for hardware requires submitting a serial number tied to a valid support contract, IIRC.Team just found out any one can register with a business mail id and download arista EOS images from their website.
Recommend you try that
