About this Guide
This book provides information about the Dell Networking OS command line interface (CLI) on the Dell PowerEdge M I/O Aggregator.
This book also includes information about the protocols and features found in the Dell Networking OS and on the Dell Networking systems
supported by the Dell Networking OS.
References
For more information about your system, refer to the following documents:
• Dell PowerEdge M I/O Aggregator Conguration Guide
• Dell PowerEdge M I/O Aggregator Getting Started Guide
• Release Notes for the Dell PowerEdge M I/O Aggregator
Topics:
• Objectives
• Audience
• Conventions
Objectives
This book is intended as a reference guide for the Aggregator CLI commands, with detailed syntax statements, along with usage
information and sample output.
This guide contains an Appendix with a list of the request for comment (RFCs) and management information base les (MIBs) supported.
NOTE
: For more information about when to use the CLI commands, refer to the
Dell PowerEdge M I/O Aggregator Conguration
Guide
for your system.
Audience
This book is intended for system administrators who are responsible for conguring or maintaining networks. This guide assumes that you
are knowledgeable in Layer 2 and Layer 3 networking technologies.
Conventions
This book uses the following conventions to describe command syntax.
Keyword
Keywords are in Courier font and must be entered in the CLI as listed.
parameter Parameters are in italics and require a number or word to be entered in the CLI.
{X} Keywords and parameters within braces must be entered in the CLI.
[X] Keywords and parameters within brackets are optional.
x|y Keywords and parameters separated by a bar require you to choose one option.
1
About this Guide 17
x||y Keywords and parameters separated by a double bar allow you to choose any or all of the options.
Information Icons
This book uses the following information symbols:
NOTE: The Note icon signals important operational information.
CAUTION: The Caution icon signals information about situations that could result in equipment damage or loss of data.
WARNING: The Warning icon signals information about hardware handling that could result in injury.
18 About this 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 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.
Topics:
• Operational Modes
• Default Settings
• Other Auto-Congured Settings
• Where to Go From Here
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 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)
2
Before You Start 19
• 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.
NOTE: You can also change many of the default settings using the chassis management controller (CMC) interface. For
information about how to access the CMC to congure an Aggregator, refer to the
Dell PowerEdge M1000e Enclosure Hardware
Owner's Manual
or
Dell Chassis Management Controller (CMC) User’s Guide
on the Dell Support website at http://
support.dell.com/support/edocs/systems/pem/en/index.htm.
Other Auto-Congured Settings
After the Aggregator powers on, it auto-congures and is operational with software features enabled, including:
• VLANs: All ports are congured as members of all (4094) VLANs. All VLANs are up and can send or receive layer 2 trac. For more
information, refer to VLANs.
• Data Center Bridging Capability Exchange Protocol (DCBX)
• Fibre Channel over Ethernet (FCoE) connectivity
• FCoE Initiation Protocol (FIP) snooping
• Hybrid ports: Ports are administratively up and auto-congured to operate as hybrid ports to transmit tagged and untagged VLAN
trac.
• iSCSI optimization
• IGMP snooping
• Jumbo frames: Ports are set to a maximum MTU of 12,000 bytes by default.
• Link aggregation: All uplink ports are congured in a single LAG (LAG 128).
• Link Layer Discovery Protocol (LLDP): Enabled on all ports.
• Link tracking: Enables server-facing links to be brought up only if the uplink port-channel (LAG 128) is up.
• Stacking: Stacking is supported only on the 40GbE ports on the base module. A single stack is limited to six Aggregators in the same
chassis. Up to three stacks are supported in an M1000e chassis. To congure a switch stack, you must use the CLI. For more
information, refer to Stacking Commands.
DCB Support
DCB enhancements for data center networks are supported to eliminate packet loss and provision links with required bandwidth.
The Aggregator provides zero-touch conguration for DCB. The Aggregator auto-congures DCBX port roles to match the DCBX
conguration in the ToR switches to which it connects through its uplink ports.
The Aggregator supports DCB only in standalone mode and not in the stacking mode.
FCoE Connectivity
Many data centers use Fibre Channel (FC) in storage area networks (SANs). Fibre Channel over Ethernet (FCoE) encapsulates Fibre
Channel frames over Ethernet networks.
On an Aggregator, the internal ports support FCoE connectivity and connect to the converged network adapter (CNA) in blade servers.
FCoE allows Fibre Channel to use 10-Gigabit Ethernet networks while preserving the Fibre Channel protocol.
The Aggregator also provides zero-touch conguration for FCoE conguration. The Aggregator auto-congures to match the FCoE
settings used in the ToR switches to which it connects through its uplink ports.
