What we do is to use the "priority" setting in the 3750 to determine who
is the master.
switch(config)#switch 1 priority 15
This will define that switch in the stack as the highest priority, then
set your next one to 14, etc etc through the stack. That way you will
always have deterministic elections.
When you lose the switch, the next one will take over.
