We have an Arista 7160 with 25GB optics and it wont link to our Windows 10 workstations using a Broadcom BCM57414 and Finisar SFP28.

No link when connecting to the switch.

What am I missing to get this to link?

Hi Justin,

Thank you for writing to the forum.

Could you paste the following here:
Show version

Which interface on the 7160 are you using?

For technical troubleshooting, you can also contact with show tech from the device.
