Master Election
The stack master is elected based on one of these factors in the order listed:
1. The switch that is currently the stack master.
2. The switch with the highest stack member priority value.
Note We recommend you assign the highest priority value to the switch that you want to be the
master. The switch is then re-elected as master if a re-election occurs.
