Issue regarding Mellanox MCX311A-XCAT ConnectX-3 EN 10G Ethernet 10GbE SFP+ PCIe NIC and how I solved it

Featured Replies

So back story, I ordered a "Mellanox MCX311A-XCAT ConnectX-3 EN 10G Ethernet 10GbE SFP+ PCIe NIC w/2 Bracket" from eBay. Everything seemed fine and was working as I assumed as expected. I noticed the next day in the logs the Mellanox nic was up and down like a yo-yo causing a bunch of issues on my network. At first I assumed I had a bad cable, or bad NIC card. (or even a bad port on my new USW-Pro-Max-24-PoE)

 

I solved the issue by installing the Mellanox Firmware Tools plugin and updated to the newest version.

 

# mstflint -d 04:00.0 -i *.bin burn

    Current FW version on flash:  2.33.5220
    New FW version:               2.42.5000

Burn process will not be failsafe. No checks will be performed.
ALL flash, including the Invariant Sector will be overwritten.
If this process fails, computer may remain in an inoperable state.

 Do you want to continue ? (y/n) [n] : y
Burning FS2 FW image without signatures - OK  
Restoring signature                     - OK

 

Once this was flashed to the latest version, all my issues went away.

 

I just wanted to drop this here, incase anyone else comes across the same issue.
