BIG-IP to Cisco via 10Gb SFP+ Direct Attach Copper

Hi,

 

Anybody using Cisco DAC 10G transceiver/copper cables (TwinAx) to connect from a Cisco switch to a BIG-IP?

 

Can't seem to find an answer, suspect it is not supported which is always an issue for DACs between vendors.

 

Cheers

    I've been using Cisco DACs for years with the smaller F5s (2000,4000 series) however I've noticed that although they work with my i7800, I did get a notification when I initially powered up that it was an "unsupported optic".

      We are seeing the same issue. The Cisco DACs work fine with the 2400 series, and we are seeing "unsupported optic"on our 5250

    Although this topic is already some years old, I hope someone can provide me the latest status for this issue.
    We are currently also facing this issue with a i2600. Tmsh list net interface displayes "Unsupported Optic detected" and interface status for 5.0 and 6.0 is DOWN.
    If I check all above comments it seems it's working for some of you and for others not.
    I also tried to verify if there is any possibility to disable the vendor-check, but I can't find anything useful.
    And more useful information would be very helpful!
    Thank you!

    Regards Stefan 🙂
