I'm not a Solaris guy so I cannot specifically address a specific fix,
but I would look at the hardware network settings on your Solaris
boxes.  We had a problem with some HPUX systems with a particular
switch where they would not auto-negotiate correctly.  We ended up
going into the bios on the systems and setting them to the 100/full
duplex mode and then they ran fine.  You may find your systems are set
to some level of AUTO and that doesn't work well with switch.

There is generally a way to have the OS report what speed or
connection the box is running at.  This may confirm if the systems and
the switch are having trouble negotiating a speed.
