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 configuration. After you power it on, an Aggregator boots up
with default settings and auto-configures with software features enabled. This chapter describes the
default settings and software features that are automatically configured at startup. Use the tasks
described in the other chapters to reconfigure 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 configure VLAN memberships. (Supported in CMC)
• Programmable MUX mode (PMUX) — stack-unit unit iom-mode programmable-mux. Select this
mode to configure 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 different chassis. This is a
low-touch mode where all configuration except VLAN membership is automated. To enable VLAN,
you must configure 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 different IOA modules. This is a low-touch mode where all configuration except
VLAN membership is automated. To enable VLAN, you must configure it. In this mode, base module
links are dedicated to VLT interconnect.
For more information, refer to the Dell PowerEdge M I/O Aggregator Configuration Guide.
Default Settings
The I/O Aggregator provides zero-touch configuration with the following default configuration 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 flooding (enabled)
18
Before You Start
• IGMP snooping in all VLANs except the default VLAN (enabled)
• VLAN configuration (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 configure 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-Configured Settings
After the Aggregator powers on, it auto-configures and is operational with software features enabled,
including:
• VLANs: All ports are configured as members of all (4094) VLANs. All VLANs are up and can send or
receive layer 2 traffic. 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-configured to operate as hybrid ports to transmit
tagged and untagged VLAN traffic.
• 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 configured 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
configure 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 configuration for DCB. The Aggregator auto-configures DCBX port
roles to match the DCBX configuration 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.
Before You Start
19
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 configuration for FCoE configuration. The Aggregator autoconfigures to match the FCoE settings used in the ToR switches to which it connects through its uplink
ports.
iSCSI Operation
Support for iSCSI traffic is turned on by default when the Aggregator powers up. No configuration is
required.
When the Aggregator powers up, it monitors known TCP ports for iSCSI storage devices on all interfaces.
When a session is detected, an entry is created and monitored as long as the session is active.
The Aggregator also detects iSCSI storage devices on all interfaces and auto-configures to optimize
performance. Performance optimization operations, such as Jumbo frame size support, STP port-state
fast, and disabling of storm control on interfaces connected to an iSCSI storage device, are applied
automatically.
CLI configuration is necessary only when the configuration includes iSCSI storage devices that cannot be
automatically detected and when non-default QoS handling is required.
Link Aggregation
In Standalone, VLT, and Stacking modes, all uplink ports are configured in a single LAG (LAG 128). There
can be multiple uplink LAGs in programmable-mux mode. Server-facing ports are auto-configured as
part of link aggregation groups if the corresponding server is configured for LACP-based NIC teaming.
Static LAGs are supported in PUX mode.
NOTE: The recommended LACP timeout is Long-Timeout mode.
Link Tracking
By default, all server-facing ports are tracked by the operational status of the uplink LAG. If the uplink LAG
goes down, the Aggregator loses its connectivity and is no longer operational; all server-facing ports are
brought down.
NOTE: If installed servers do not have connectivity to a ToR switch, check the Link Status LED of
uplink ports on the Aggregator. If all LEDs are ON, check the LACP configuration on the ToR switch
that is connected to the Aggregator to ensure the LACP is correctly configured.
VLANs
By default, all Aggregator ports belong to all 4094 VLANs and are members of untagged VLAN 1. You can
use the CLI or CMC interface to configure only the required VLANs on a port.
20
Before You Start
When you configure VLANs on server-facing interfaces (ports 1 to 32), you can assign VLANs to a port or
a range of ports by entering the vlan tagged or vlan untagged commands in interface configuration
mode; for example:
Dell(conf)# interface tengigabitethernet 0/2 - 4
Dell(conf-if-range-te-0/2-4)# vlan tagged 5,7,10-12
Dell(conf-if-range-te-0/2-4)# vlan untagged 3
NOTE: You can also use the CMC interface to configure VLANs.
Uplink LAG
The tagged VLAN membership of the uplink LAG is automatically configured based on the tagged and
untagged VLAN configuration of all server-facing ports (ports 1 to 32).
The untagged VLAN used for the uplink LAG is always the default VLAN.
Server-Facing LAGs
The tagged VLAN membership of a server-facing LAG is automatically configured based on the serverfacing ports that are members of the LAG.
The untagged VLAN of a server-facing LAG is configured based on the untagged VLAN to which the
lowest numbered server-facing port in the LAG belongs.
NOTE: Dell Networking recommends that you configure the same VLAN membership on all LAG
member ports.
Stacking Mode
When you configure an Aggregator to operate in stacking mode (See “Configuring and Bringing Up a
Stack” in the Dell Networking Configuration Guide for the M I/O Aggregator), VLANs are reconfigured as
follows:
If an Aggregator port belonged to all 4094 VLANs in standalone mode (default), all VLAN membership is
removed and the port is assigned only to default VLAN 1. You must configure additional VLAN
membership as necessary.
If you had manually configured an Aggregator port to belong to one or more VLANs (non-default) in
standalone mode, the VLAN configuration is retained in stacking mode only on the master switch
When you reconfigure an Aggregator from stacking to standalone mode:
Aggregator ports that you manually configured for VLAN membership in stacking mode retain their VLAN
configuration in standalone mode.
To restore the default auto-VLAN mode of operation (in which all ports are members of all 4094 VLANs)
on a port, enter the auto vlan command; for example:
Dell(conf)# interface tengigabitethernet 0/2
Dell(conf-if-te-0/2)# auto vlan
To get the default standalone mode configurations:
1. Delete the startup-config file and reboot the system.
Before You Start
21
2. Restore to factory default settings.
3. Configure auto vlan command on all the server ports.
Where to Go From Here
You can customize the Aggregator for use in your data center network as necessary. To perform
additional switch configuration, do one of the following:
• For remote out-of-band management, enter the OOB management interface IP address into a Telnet
or SSH client and log in to the switch using the user ID and password to access the CLI.
• For local management using the CLI, use the attached console connection.
• For remote in-band management from a network management station, enter the VLAN IP address of
the management port and log in to the switch to access the CLI.
If you installed the Aggregator in a stack, you can configure additional settings for switch stacking
In case of a Dell Networking OS upgrade, you can check to see that an Aggregator is running the latest
Dell Networking OS version by entering the show version command. To download a Dell Networking OS
version, go to http://support.dell.com.
Refer to the appropriate chapter for detailed information on how to configure specific software settings.

CLI Basics
This chapter describes the command line interface (CLI) structure and command modes. The Dell
operating system commands are in a text-based interface that allows you to use the launch commands,
change command modes, and configure interfaces and protocols.
Accessing the Command Line
When the system boots successfully, you are positioned on the command line in EXEC mode and not
prompted to log in. You can access the commands through a serial console port or a Telnet session.
When you Telnet into the switch, you are prompted to enter a login name and password.
Example
After you log in to the switch, the prompt provides you with the current command-level information. For
example:
Prompt
Dell>
Dell#
Dell(conf)#
NOTE: For a list of all the command mode prompts, refer to the Command Modes Modes section.
telnet 172.31.1.53

CONFIGURATION
Multiple Configuration Users
When a user enters CONFIGURATION mode and another user is already in CONFIGURATION mode, the
Dell operating system generates an alert warning message similar to the following:
Dell#conf
% Warning: The following users are currently configuring the system:
User "" on line console0
User "admin" on line vty0 ( 123.12.1.123 )
User "admin" on line vty1 ( 123.12.1.123 )
CLI Basics
23
User "Irene" on line vty3 ( 123.12.1.321 )
Dell#conf
When another user enters CONFIGURATION mode, the Dell Networking OS sends a message similar to
the following:
% Warning: User "admin" on line vty2 "172.16.1.210" is in configuration
In this case, the user is “admin” on vty2.
Navigating the CLI
The Dell Networking OS displays a CLI prompt comprised of the host name and CLI mode.
• Host name is the initial part of the prompt and is “Dell” by default. You can change the host name with
the hostname command.
• CLI mode is the second part of the prompt and reflects the current CLI mode. For a list of the Dell
Networking OS command modes, refer to the command mode list in the Accessing the Command
Line section.
The CLI prompt changes as you move up and down the levels of the command structure. Starting with
CONFIGURATION mode, the command prompt adds modifiers to further identify the mode. For more
information about command modes, refer to the Command Modes section.

Filtering show Commands
To find specific information, display certain information only or begin the command output at the first
instance of a regular expression or phrase, you can filter the display output of a show command.
When you execute a show command, and then enter a pipe ( | ), one of the following parameters, and a
regular expression, the resulting output either excludes or includes those parameters.
26
CLI Basics
NOTE: The Dell Networking OS accepts a space before or after the pipe, no space before or after
the pipe, or any combination. For example: Dell#command | grep gigabit |except
regular-expression | find regular-expression.
except
find
grep
no-more
save
The grep command option has an ignore-case sub-option that makes the search case-insensitive. For
example, the commands:
• show run | grep Ethernet returns a search result with instances containing a capitalized “Ethernet,”
such as interface TenGigabitEthernet 0/1.
• show run | grep ethernet does not return the search result above because it only searches for
instances containing a non-capitalized “ethernet”.
• show run | grep Ethernet ignore-case returns instances containing both “Ethernet” and “ethernet”.
displays only the text that does not match the pattern (or regular expression)
searches for the first occurrence of a pattern
displays text that matches a pattern.
does not paginate the display output
copies the output to a file for future use
Displaying All Output
To display the output all at once (not one screen at a time), use the no-more option after the pipe. This
operation is similar to the terminal length screen-length command except that the no-more
option affects the output of just the specified command. For example:
Dell#show running-config|no-more
Filtering the Command Output Multiple Times
You can filter a single command output multiple times. To filter a command output multiple times, place
the save option as the last filter. For example:
Dell# command | grep regular-expression | except regular-expression | grep
other-regular-expression | find regular-expression | no-more | save
Command Modes
To navigate and launch various CLI modes, use specific commands. Navigation to these modes is
described in the following sections.
EXEC Mode
When you initially log in to the switch, by default, you are logged in to EXEC mode. This mode allows you
to view settings and enter EXEC Privilege mode, which is used to configure the device.
When you are in EXEC mode, the > prompt is displayed following the host name prompt, which is “Dell”
by default. You can change the host name prompt using the hostname command.
CLI Basics
27
NOTE: Each mode prompt is preceded by the host name.
EXEC Privilege Mode
The enable command accesses EXEC Privilege mode. If an administrator has configured an “Enable”
password, you are prompted to enter it.
EXEC Privilege mode allows you to access all the commands accessible in EXEC mode, plus other
commands, such as to clear address resolution protocol (ARP) entries and IP addresses. In addition, you
can access CONFIGURATION mode to configure interfaces, routes and protocols on the switch. While
you are logged in to EXEC Privilege mode, the # prompt displays.
CONFIGURATION Mode
In EXEC Privilege mode, use the configure command to enter CONFIGURATION mode and configure
routing protocols and access interfaces.
To enter CONFIGURATION mode:
1. Verify that you are logged in to EXEC Privilege mode.
2. Enter the configure command. The prompt changes to include (conf).
From this mode, you can enter INTERFACE mode by using the interface command.
INTERFACE Mode
To configure interfaces or IP services on those interfaces, use INTERFACE mode. An interface can be
physical (for example, a TenGigabit Ethernet port) or virtual (for example, the VLAN interface).
To enter INTERFACE mode:
1. Verify that you are logged in to CONFIGURATION mode.
2. Enter the interface command and then enter an interface type and interface number that is
available on the switch.
The prompt changes to include the designated interface and slot/port number. For example:
Prompt Interface Type
Dell(conf-ifte-0/1)#
Dell(conf-ifvl-1)#
Dell(conf-ifma-0/1)#
Dell(conf-ifrange)#
Ten-Gigabit Ethernet interface then slot/port information
VLAN Interface then VLAN number (range 1–4094)
Management Ethernet interface then slot/port information
Designated interface range (used for bulk configuration)
LINE Mode
To configure the console or virtual terminal parameters, use LINE mode.
To enter LINE mode:
28
CLI Basics
1. Verify that you are logged in to CONFIGURATION mode.
2. Enter the line command. Include the keywords console or vty and their line number available on
the switch. The prompt changes to include (config-line-console) or (config-line-vty).
You can exit this mode by using the exit command.
MONITOR SESSION Mode
In CONFIGURATION mode, use the monitor session command to enter MONITOR SESSION mode
and configure port monitoring.
To enter MONITOR SESSION mode:
1. Verify that you are logged in to CONFIGURATION mode.
2. Use the monitor session command. Include the monitor session ID. The prompt changes to
include (conf-mon-sess).
You can return to CONFIGURATION mode by using the exit command.
PROTOCOL LLDP Mode
In CONFIGURATION mode, use the protocol lldp command to enter PROTOCOL LLDP mode and
configure the LLDP protocol.
To enter PROTOCOL LLDP mode:
