Influence Management Unit Selection on an S-Series Stack
Stack Priority is the system variable that FTOS uses to determine which units in the stack will be the
primary and secondary management units. If multiple units tie for highest priority, then the unit with the
highest MAC address prevails.
If management was determined by priority only, a change in management occurs when:
• you powered down, or offline the management unit, or a failover occurs
• you disconnect the management unit from the stack
Task Command Syntax Command Mode
Influence the selection of the stack management units. The unit with the
numerically highest priority is elected the primary management unit,
and the unit with the second highest priority is the secondary
management unit.
