The Port Aggregator feature is available when the switch is in Simple mode; the PowerConnect™ M8024-k switch operates in Simple mode by default. The PowerConnect M6220, M6348 and M8024 switches operate in normal mode by default, and Simple mode is disabled. A user can select the operational mode as Simple or Normal mode from the Dell™ CLI setup wizard; users with privilege level 15 may change the mode using the CLI, web and SNMP user interfaces.
