2000 collisions in an of itself is completely meaningless.  My guess is
that you had more in the past, but you just weren't looking.  Just make
sure that your switch port isn't been swamped and that flow control is
turned of as appropriate.  Since this port is being connected to a hub,
locking the switch port to half duplex would be a must.  I'm not
familiar with the 928's or the 3K boxes you're alluding to so I can't
speak about ti.
