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.I'd like to know if its possible to use non-arista DAC's from FS like the generic ones or Mellanox to save a few $?
I understand there was two methods to allow 3rd party DAC's however I can't find a definitive answer in this thread so I'm posted again.
I would like to use these for a Lab with some Chelsio T580 cards, does anybody have experience is this is reported working?
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.
