Frequently Asked Questions
•
Do you support AutoNeg at 25G speed?
Yes. Please refer to
“Auto-Negotiation Configuration” on page 40
for more details.
•
How would I connect SFP28 cable to QSFP ports?
Breakout cables are available from QSFP to 4xSFP28 ports.
•
What are the compatible port speeds?
For BCM57404AXXXX/BCM57414 dual-port devices, the port speed of each port must be compatible with
the port speed of the other port. 10 Gbps and 25 Gbps are not compatible speed. If one port is set to 10 Gbps
the other port can not be set to 25 Gbps. If user attempt to set incompatible port speeds, the second port to
be brought up will not link. Please refer to
“Auto-Negotiation Configuration” on page 40
for more details.
•
Can I use 10 Gbps for PXE connectivity on a 25 Gbps port?
Currently only 25 Gbps PXE speed is supported. It is not recommended to use 10 Gbps PXE connectivity
on a 25 Gbps adapter. This is due to the lack of support for auto negotiation on existing 10 Gbps switches
and possible complications caused by incompatible port link speed settings.
