Any stacking-enabled switch can become a Commander as long as the intended stack name does not already exist on the broadcast domain. This is because creating a Commander automatically creates a corresponding stack.
Before you begin configuring stacking parameters:
-
Configure IP addressing on the switch intended for stack commander and, if not already configured, on the primary VLAN. (For more on configuring IP addressing, see the Management and Configuration Guide for your switch.)

NOTE: The primary VLAN must have an IP address in order for stacking to operate properly. For more on the primary VLAN, see The primary VLAN.
-
Configure a Manager password on the switch intended for Commander; (the Commander's Manager password controls access to stack Members). For more on passwords, see the local manager and operator password information in the Access Security Guide for your switch.
