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. Robert Hayden Unviversity of Wisconsin Madison On Wed, 29 Sep 2004, Bill Woodcock wrote:

...and the stacking interface is actually pretty lousy, from our testing. We were anticipating really liking it, but we haven't touched it again, since our lab work. Obviously it precludes hot-swappability, but beyond that, using it wipes any preexisting configuration on all but the first box (and out of two, I don't know how to predict which it will decide is first, in advance), and it leaves the port-numbering screwed up on any boxes that have used it, in perpetuity.
