Enabling and Disabling the Stacking-Support Option

The stacking-support option is automatically enabled for many Summit switch and option card configurations. However, some Summit switch and option card configurations require you to enable the stacking-support option before a switch can participate in a stack. The preceding table indicates which switch and option cards require you to enable the stacking-support option. If the Stacking-Support Option Control column in this table displays Yes, the stacking-support option must be enabled before the switch can join a stack.
