Cisco Nexus 93180YC Switch Feedback

Dear Nanog

Just wondering if anyone is using the Cisco Nexus 93180YC with the LAN enterprise license and has any honest feedback about this platform, especially if you are using VXLAN routing and eVPN, would love to hear from you.

For those that don't know the Cisco Nexus 93180YC is a 1RU switch with 48 x 25gbit ports SFP+ ports (1G, 10G or 25G) + 6 x 100gbit QSFP uplink ports. (40G, 50G or 100G)

Kindest Regards

James Braunegg

We’ve started testing them, as well as the 92160YCX and C92300YC, for IXP use. Notably only four of the six 100G ports on the 92160YCX will run at 100G, leaving two at 40G.

Anybody had any luck sourcing 2x25G NICs for Cisco UCS servers?

Actually, only two.

You can configure how the ports present themselves...

I'll claim correctness on a technicality :wink:

Since the original statement was: "Notably only four of the six 100G ports on the 92160YCX will run at 100G, leaving two at 40G."

In the default mode, you get 4 x 40G + 2 x 100G. Good point that there is an optional mode which is 4 x 100G - but there is no 40G in that mode, ports 53-54 are disabled in that mode.

Thanks,
Tim

You have to tell it you want more 100G with fewer ports
