running-config synchronization also occurs when the running configuration is
automatically saved on the stack management switch or when the standby unit changes.
Stack management switch election
All stack members are eligible stack management switches. If the stack management
switch becomes unavailable, the remaining stack members participate in electing a new
stack management switch from among themselves. The following factors determine
which switch is elected as the stack management switch:
• Current role: The switch that is management switch always has priority to retain the
role of management switch.
• Assigned priority
• MAC address
When the stack is powered up and completes the boot process or the original stack
management switch becomes unavailable, the stack management switch is determined
through an election process.
The rules for stack management switch election are as follows:
• If a unit was elected stack management switch previously, then it remains the stack
management switch and other units are stack members.
• If no units were stack management switches, or more than one unit was a stack
management switch, then the unit with the highest management priority is elected
stack management switch. You can assign the management priority. However, if all
units are assigned the same management priority, then the unit with the highest
MAC address is assigned as the stack management switch.
Stack factory defaults reset
behavior
If the stack management switch is reset to the factory default settings (see Reset the
switch to the factory default settings on page 880), the stack management switch applies
the default settings to all the stack members and resets the stack, including all
participating stack members. When the stack boots, the stack management switch
election process begins.
