All the stand-alone switches I've looked at recently either do not support 802.3x or support it in the (desireable) manner described in the last paragraph of the linked blog post. I don't believe Ethernet flow control is a factor in current LANs. I'd be interested to know the specifics if anyone sees it differently.
My understanding is that 802.1au, "lossless Ethernet", was designed primarily to allow Fibre Channel to be carried over 10 GbE so that SAN and LAN can share a common infrastructure in datacenters. I don't believe anyone intends for it to be enabled for traffic classes carrying TCP.

It can cause trouble even in small environments as your house. http://virtualthreads.blogspot.com/2006/02/beware-ethernet-flow-control.html I know I'm at least three consumer switches deep, and it's not by choice. - Jim _______________________________________________ Bloat mailing list [email protected] https://lists.bufferbloat.net/listinfo/bloat
