Oldroyd changed: What |Removed |Added ---------------------------------------------------------------------------- Resolution|Not A Bug |--- Status|Closed |Open --- Comment #2 from J.R. Oldroyd --- Stefan, I believe you are mis-reading the standard. You are quoting what the standard says to do in the event of autonegotiation failure. In that event, setting half-duplex is indeed the required behavio= r. However, citing from the same article that you cited, "The Ethernet standar= ds and major Ethernet equipment manufacturers recommend enabling autonegotiati= on." If both ends of a link are not under common administrative control, it may = not be possible to set both ends to matching modes. Clearly, having a device inform the other end what its configured capabilities are is preferable to having a non-working link. --=20 You are receiving this mail because: You are the assignee for the bug.=
