Consistency of Stack Unit Modes in the Stack
All units in the stack must have the same stack unit mode.
When the stack is initialized, it runs a topology discovery algorithm that collects
information on the units of the stack.
After a unit is selected to become the master, it can reject its neighbor’s request to
join the stack if it has an inconsistent stack unit mode. When a unit is rejected
because of its stack unit mode, it is logically shutdown (the ports cannot send/
receive traffic) and all its LEDs (system, FAN, unit IDs, network ports and stack
ports LEDs) are turned on. The information regarding the stack unit mode is
displayed as a SYSLOG error in the master unit.
