Users Guide

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 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.

• Default Settings

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, 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
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,
base module links are dedicated to VLT interconnect.
