How is the Stack Master Selected?
A stack master is elected or re-elected based on the following considerations,
in order:
1
The switch is currently the stack master.
2
The switch has the higher MAC address.
3
A unit is selected as standby by the administrator, and a fail over action is
manually initiated or occurs due to stack master failure.
In most cases, a switch that is added to an existing stack will become a stack
member, and not the stack master. When a switch is added to the stack, one
of the following scenarios takes place regarding the management status of the
new switch:
• If the switch has the stack master function enabled but another stack
master is already active, then the switch changes its configured stack
master value to disabled.
• If the stack master function is unassigned and there is another stack
master in the system then the switch changes its configured stack master
value to disabled.
