well, how bad...
I've seen about every sun box here not negotiate duplex correctly with their
switch so we've had to force set all sun 100 Mb/sec fast Ethernet interfaces
to full duplex, 100 Mb AND force set the switch ports they connect to also.
If auto negotiate is involved anywhere in there, something always gets
screwed up and backup speeds drop to about 10 MB/hr
ARG !
I cut all my hair off long ago to keep from pulling it out !

I have yet to see a server correctly detect duplex when set to
auto-negotiate with a switch. Not just Sun, but every other vendor we
have as well. In fact a few years back, even the cisco engineers didn't
rate the chances of seeing a successful suto-negotiation for duplex.
Speed is OK, but everything just seems to grab half duplex when they
should be full...

Subject: High Comm Wait (slow network speed?)


Hi TSMers

TSM Server 4.2.2.12 running on Solaris 2.7

Clients are OS/2, NT, Solaris and Linux

We have recently installed Servergraph and are seeing very poor comm wait
(network speed) figures for many of our machines, mostly local Sun servers.
We have tested FTP'ing some large files to and from the TSM server and
clients and the network seems fine. I'm sure I haven't included enough info
here, so please feel free to ask questions.

Are there tuning params on the TSM client itself that I may need to be
looking at that may be causing these problems?

Many thanks in advance
