Sadly neither of these are fixable without disassembling the bootloader (the Brocade bootloader is what's responsible for initializing the PHY. It also remains running at all times acting as a scheduler for the main OS). Once you find these configuration values in the disassembled bootloader they can be changed to appropriate values for the Quanta chassis and re-compiled. I received an estimate from a firmware engineer of approximately $2000 USD for this amount of reverse engineering, which I'm not willing to spend for a management port I never use on a $300 switch.
## Emergency Workaround
As it's entirely a software issue (the port goes right back to working perfectly when reverting to Fastpath software), it can be forced to link in emergency situations with a temporary software trick.
If you're in the 1% where it stops linking completely under the Brocade firmware, you can temporarily bring it back. As it's entirely a software issue (the port goes right back to working perfectly when reverting to Fastpath software), it can be forced to link in emergency situations with a temporary software trick.
If you find yourself in a situation where you must have the management port link up and it won't, follow the below. To reiterate, we've only seen it completely cease linking twice in a hundred flashed chassis.
