Aegis-GPU4.8 Transceiver firmware
Querying module firmware and why each side updates only its near-end modules.
Key points
MFT (NVIDIA Firmware Tools) includes flint, the firmware burning tool. With --linkx, flint works on the cable or transceiver attached to a device port instead of the device itself.
What NVIDIA says (2)
“Query the Transceiver firmware information.”
“flint -d lid-1 --linkx --downstream_device_ids 1 q”
A cable has a module at each end. NVIDIA says each NIC or switch can update only its own attached modules.
What NVIDIA says (2)
“Each device (NIC, Switch) can update only the modules connected directly to it, not the far end.”
“Updating the far-end transceiver requires the same operation to be done at the far-end switch(es).”
Key terms
- Transceiver: The module at a cable end that sends and receives the signal; optical and copper types use different firmware.
Sample question
Using MFT, how do you query transceiver firmware through a switch?
