Priority Flow Control (PFC) IEEE 802.1Qbb
I have a few projects going on right now for some clients involving the M4300-16X. While doing some research trying to meet some requirements, I noticed that PFC may not have been implemented for this...

Hi kc6108
As I said, PFC is hardware dependent, not software dependent - the underlying Switch Chipset in M4300-8X8F (XSM4316S) and M4300-16X (XSM4316PA and XSM4316PB) is the same and it's not supporting PFC.
I hope this helps - everything above in this thread remains true and I hope can be confirmed in the M4300 datasheet for you.

Thank you for your quick reply LaurentMa
I'm fully aware that PFC will never work on the M4300-8X8F (XSM4316S) switches due to hardware incompatibilities. I remember discovering PFC wasn't supported a couple of years ago... just about the time Netgear realized it as well and had to update the datasheets.
I was actually hoping that since both of the M4300-16X switches, the XSM4316A and XSM4316B, were just released (just over a year ago) that measures would have been taken to ensure PFC would be compatible... if at all possible.
Would you please check with engineering to ensure PFC is still a no go with the much newer 16-port switches in question?
Many thanks,
Curtis
