I have a 4.1-S, and a 4.3-S server both with a 3com 3C985 going into a summit 1, neither of which I have any problems with. The summit 1 goes into a summit 48 in both cases, and feeds Macintosh/PC/Unix workstations at 100Mbit. Doing an FTP transfer from one of these to a 100Mb connected station gives: ftp> get "08 - Out There Somewhere- (part 2).mp3" local: 08 - Out There Somewhere- (part 2).mp3 remote: 08 - Out There Somewhere- (part 2).mp3 150 Opening BINARY mode data connection for '08 - Out There Somewhere- (part 2).mp3' (13304956 bytes). 100% |*************************************************************************** *********************************************| 12993 KB 00:00 ETA 226 Transfer complete. 13304956 bytes received in 1.12 seconds (11.29 MB/s) Which is about as good as it gets, I reckon!

Blanchard Sent: 19 June 2001 14:41 To: stable@FreeBSD.ORG Subject: gigabit woes (still) a quick summary: we tried installing two different gigabit nics into one of our backup servers. first we tried device wx, then device ti. both autonegotiated to 1000Mb fdx; but provided only 2.67MB/s transfer rates. backing out to the original 100Mb fdx card left us still with 2.67MB/s transfer rates. so our backup server is currently in this 2.67MB/s limbo. i then installed device ti into another test box with a working 100Mb fdx nic. the same problem arose. i removed the card, installed several different types of 100Mb fdx nics and all were frozen at 2.67MB/s with no errors at the box or at the switch. the only way i was able to get that box back to a realistic 100Mb fdx state was by reinstalling the machine. obviously, reinstalling the backup server is a last effort and a not very likable solution. any ideas on how to get this production beast back to 100Mb fdx? (forcing the connection at both ends has no effect). finally, has anyone else found gigabit networking with freebsd and extreme switching hardware incompatible? i must conclude that this is the case as we've tried multiple gigabit nics in multiple freebsd boxes attached to various extreme switches using multiple fiber cables. -- ------------------------------------ Robin P.
