A: The stacking function is enabled by default. If stack commands cannot be executed on your switch, the switch does not support stacking.
Whether a switch supports stacking is determined by the switch hardware. If you require the stacking function, you can only replace your switch with the stacking-supporting switch model. If your switch does not support stacking, the switch cannot be upgraded to support stacking.
