Hello Folks,
We're having performance problems when connecting any of our new Sun
servers to our network via copper gig ports. This includes both Sun
V480s and V240s using ether a ce or gbe device. We have link
established through auto negotiation and the Suns work just fine from
some 10/100 ports on the same switch. We've disabled 802.1q and
spanning tree per Archive suggestions and it did not help. The
performance is < 1mb/s using iozone but I'm able to duplicate the
symptoms with cp or ftp. We have the latest kernel,nfs and gig patches
for ce and bge. We have also provided snoop data to Sun and haven't
heard back from them at this point in time. Does anyone out there in
Sun land have the magical recipe or suggestions that could help us out?
Thanks in advance, Cedo Vicente
