Before You Start

By following the instructions in the Dell PowerEdge M I/O Aggregator Getting Started Guide that is shipped with the product, you install

the Aggregator in a Dell PowerEdge M1000e Enclosure.

The Aggregator installs with zero-touch configuration. After you power it on, an Aggregator boots up with default settings and auto-

configures with software features enabled. This chapter describes the default settings and software features that are automatically

configured at startup. Use the tasks described in the other chapters to reconfigure the Aggregator for customized network operation.

Operational Modes

The FN I/O Module supports four operational modes. Select the operational mode that meets your deployment needs. To enable a new

operational mode, reload the switch.

• Standalone mode — stack-unit unit iom-mode standalone. This is the default mode for IOA. It is fully automated zero-

touch mode that allows you to configure VLAN memberships. (Manageable through CMC also)

• Programmable MUX mode (PMUX) — stack-unit unit iom-mode programmable-mux. Select this mode to configure

PMUX mode CLI commands.

• Stacking mode — stack-unit unit iom-mode stacking. Select this mode to stack up to six IOA stack units as a single

logical switch. The stack units can be in the same or on different chassis. This is a low-touch mode where all configuration except

VLAN membership is automated. To enable VLAN, you must configure it. In this operational mode, base module links are dedicated to

stacking.

• Virtual Link Trunking mode (VLT) — stack-unit unit iom-mode vlt. Select this mode to multi-home server interfaces to

different IOA modules. This is a low-touch mode where all configuration except VLAN membership is automated. To enable VLAN, you

must configure it. In this mode, base module links are dedicated to VLT interconnect.

For more information, see the Dell PowerEdge M I/O Aggregator Configuration Guide.
