Has anyone got this to work if you tried?

Insight:

• Aruba 9240 to Cisco 9500 catalyst
  • Links right up with Cisco 25G DAC cables
  • Tried an Aruba 25G DAC and can't get it to come up.
• On the Cisco end I've tried
  • service unsupported-transceivers
  • no errordisable gbic-transceiver
  • set the speed 25000 and duplex full
  • tried all FEC values - off seems to be best to get just a not connect state but line protocol is still Down
• On the Aruba 9240 can't seem to hardcode the speed to 25G or set the FEC value which seems to be the biggest hold up or possibly the main issues. Opened a TAC case see what they say.

Anything work for anyone on here if you have the same setup?

TIA
