Stack
The Supermicro Intelligent switch supports stacking of Supermicro switch units. Switch
stacking is created by connecting switches in a daisy chain. One of the stacked switches
is selected as a Master based on its configurations. The Master switch provides
management support for the whole stack. Other switches in the stack are referred to as
slave switches.
The Master switch manages the control plane traffic for all stacked switches. When the
current master switch fails, the backup master is then selected as the current master.
The Master selection algorithm is based on a priority configuration. If two switches have
the same priority, the switch with the lowest MAC address is selected as the Master
switch.
