CLI Guide

Before You Start

By following the instructions in the Dell PowerEdge FN I/O Aggregator Getting Started Guide that is

shipped with the product, you install the Aggregator in a Dell PowerEdge FX2 server chassis.

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 I/O Aggregator 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, ports 9 and 10 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,

ports 9

is configured as VLT interconnect.

• Full Switch mode — stack-unit unit iom-mode full-switch. The full switch mode provides

Layer 2 / Layer 3 functionalities on the Dell FX2 chassis. All the commands and configurations

supported on the MXL is available in full-switch mode.
