Administrator Guide

Before You Start

To install the FN IOM in a Dell FX2 server chassis, use the instructions in the Dell Networking FN IOM Getting

Started Guide that is shipped with the product. The FN IOM installs with zero-touch configuration. After you

power it on, it boots up with default settings and auto-configures with software features enabled. This topic

describes the default settings and software features that are automatically configured at startup. To

reconfigure the FN IOM for customized network operation, use the tasks described in the other topics.

Operational Modes

FN IOM supports five 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

CONFIGURATION mode

Dell(conf)#stack-unit 0 iom-mode standalone

This mode is the default mode for IOA. It is a fully automated zero-touch mode that allows you to configure

VLAN memberships. (Supported in CMC)

VLT mode

stack-unit unit iom-mode vlt

CONFIGURATION mode

Dell(conf)#stack-unit 0 iom-mode vlt

Select this mode to multihome server interfaces to different IOA modules. This mode is a low-touch mode

where all configuration except VLAN membership is automated. To enable VLAN, configure the VLANs at the

server port level. In this mode, port 9 link, which is associated with LAG-127, is dedicated to VLT interconnect.
