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

13304956 bytes received in 1.12 seconds (11.29 MB/s)

Which is about as good as it gets, I reckon!

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.
