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 conguration. After you power it on, an Aggregator boots up with default settings and auto-
congures with software features enabled. This chapter describes the default settings and software features that are automatically
congured at startup. Use the tasks described in the other chapters to recongure 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 congure VLAN memberships. (Supported in CMC)
• Programmable MUX mode (PMUX) — stack-unit unit iom-mode programmable-mux. Select this mode to congure PMUX
mode CLI commands.
• Stacking mode — stack-unit unit iom-mode stacking. Select this mode to stack up to 6 IOA stack units as a single logical switch.
The stack units can be in the same or on dierent chassis. This is a low-touch mode where all conguration except VLAN
membership is automated. To enable VLAN, you must congure 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 dierent
IOA modules. This is a low-touch mode where all conguration except VLAN membership is automated. To enable VLAN, you
must congure it. In this mode, base module links are dedicated to VLT interconnect.
For more information, refer to the Dell PowerEdge M I/O Aggregator Conguration Guide.
Default Settings
The I/O Aggregator provides zero-touch conguration with the following default conguration settings:
• Default user name (root)
• Password (calvin)
• VLAN (vlan1) and IP address for in-band management (DHCP-assigned)
• IP address for out-of-band (OOB) management (DHCP-assigned)
• Read-only SNMP community name (public)
• Broadcast storm control (enabled)
• Unregistered Multicast Packets ooding (enabled)
• IGMP snooping in all VLANs except the default VLAN (enabled)

You can change any of these default settings using the CLI. Refer to the appropriate chapter for details.
