Description: The Stacking Mode Status for the switch module. standby - I/O module has stacking capability but is not part of a stack. member - I/O module has stacking capability and is part of a stack in the member role. master - I/O module has stacking capability and is part of a stack in the master role. NOTE: The term disabled was changed to the term standby to be more descriptive.
What is smStackingModeState?
This read-only enum reports a switch module's role in a hardware stack: standby (stacking-capable but not part of a stack), member, or master, or notApplicable if it lacks stacking capability, with the MIB noting the term 'disabled' was renamed to 'standby' for clarity. It matters for understanding which switch module in a stacked configuration currently has master-level control versus acting as a subordinate member. An admin diagnosing unexpected switch behavior in a stacked I/O module setup would check smStackingModeState to confirm which module currently holds the master(2) role.
