CLI Guide

Before You Start

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

FN I/O Module in a Dell PowerEdge FX2 server chassis.

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

congures with software features enabled. This chapter describes the default settings and software features that are automatically

congured at startup. Use the tasks described in the other chapters to recongure the Aggregator for customized network operation.

Topics:

• Operational Modes

• Default Settings

• Other Auto-Congured Settings

• DCB Support

• FCoE Connectivity

• iSCSI Operation

• Link Aggregation

• Uplink Failure Detection

• VLANs

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 congure VLAN memberships. (Manageable through CMC also)

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

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 dierent chassis. This is a low-touch mode where all conguration except VLAN

membership is automated. To enable VLAN, you must congure 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

dierent IOA modules. This is a low-touch mode where all conguration except VLAN membership is automated. To enable VLAN, you

must congure it. In this mode, ports 9 is congured 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 congurations supported on the MXL is available in full-switch mode.
