Influencing Management Unit Selection on a
Stack
Stack priority is the system variable that Dell Networking OS uses to determine which units in the stack are the
master and standby management units. If multiple units tie for highest priority, the unit with the highest MAC
address prevails.
If management was determined by priority only, a change in management occurs when:
• the management unit is powered down or a failover occurs.
• you disconnect the management unit from the stack.
