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. (Manageable through CMC also)
• 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 six 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, see 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)
• VLAN conguration (all ports belong to all VLANs)
You can change any of these default settings using the CLI. Refer to the appropriate chapter for details.
