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 Trying 172.31.1.53... Connected to 172.31.1.53. Escape character is '^]'. Login: username Password: Dell>
CLI Command Mode
EXEC
EXEC Privilege
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.
Prompt CLI Command Mode

Obtaining Help

As soon as you are in a command mode there are several ways to access help.
To obtain a list of keywords at any command mode:
To obtain a list of keywords with a brief functional description:
To obtain a list of available options:
To obtain a list of partial keywords using a partial keyword:
Example
When entering commands, you can take advantage of the following timesaving features:
Type a ? at the prompt or after a keyword. There must always be a space before the ?.
Type help at the prompt.
Type a keyword and then type a space and a ?.
Type a partial keyword and then type a ?.
The following is an example of typing ip ? at the prompt:
Dell(conf)#ip ? igmp Internet Group Management Protocol route Establish static routes telnet Specify telnet options
The commands are not case-sensitive.
You can enter partial (truncated) command keywords. For example, you can enter int tengig int for the interface tengigabitethernet interface command.
To complete keywords in commands, use the TAB key.
To display the last enabled command, use the up Arrow key.
To erase the previous character, use either the Backspace key or Delete key.
To navigate left or right in the Dell Networking OS command line, use the left and right Arrow keys.
The shortcut key combinations at the Dell Networking OS command line are as follows:
Key Combination Action
CNTL-A Moves the cursor to the beginning of the command line.
CNTL-B Moves the cursor back one character.
CNTL-D Deletes the character at the cursor.
CNTL-E Moves the cursor to the end of the line.
CNTL-F Moves the cursor forward one character.
CNTL-I Completes a keyword.
CLI Basics
25
Key Combination Action
CNTL-K Deletes all the characters from the cursor to the end of the command line.
CNTL-L Re-enters the previous command.
CNTL-N Returns to the more recent commands in the history buffer after recalling
commands with Ctrl-P or the up Arrow key.
CNTL-P Recalls commands, beginning with the last command.
CNTL-U Deletes the line.
CNTL-W Deletes the previous word.
CNTL-X Deletes the line.
CNTL-Z Comes back to EXEC mode from any CONFIGURATION mode.
Esc B Moves the cursor back one word.
Esc F Moves the cursor forward one word.
Esc D Deletes all the characters from the cursor to the end of the word.

Using the Keyword no Command

To disable, delete or return to default values, use the no form of the commands. For most commands, if you type the keyword no in front of the command, you disable that command or
delete it from the running configuration. In this guide, the no form of the command is described in the Syntax portion of the command description. For example:
Syntax
Defaults None
Command Modes
Command History
no {boot | default | enable | ftp-server | hardware | hostname | ip | line | logging | monitor | service | io-aggregator broadcast storm-control | snmp-server | username}
CONFIGURATION
Version 8.3.17.0 Supported on the M I/O Aggregator.

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:
1. Verify that you are logged in to CONFIGURATION mode.
2. Enter the protocol lldp command. The prompt changes to include Dell(config-lldp).
You can return to CONFIGURATION mode by using the exit command.

Important Points:
The SWP provides flow control-based reliable communication between the sending and receiving software tasks.
A sending task enqueues messages into the SWP queue3 for a receiving task and waits for an acknowledgement.
If no response is received within a defined period of time, the SWP timeout mechanism resubmits the message at the head of the FIFO queue.
After retrying a defined number of times, the SWP-2-NOMORETIMEOUT timeout message is generated.
In the example, a retry (Retries) value of zero indicates that the SWP mechanism reached the maximum number of retransmissions without an acknowledgement.

Data Center Bridging (DCB)

Data center bridging (DCB) refers to a set of IEEE Ethernet enhancements that provide data centers with a single, robust, converged network to support multiple traffic types, including local area network (LAN), server, and storage traffic. DCB features are auto-configured in standalone mode and supported in stacking mode.
The Dell Networking OS commands for DCB features include 802.1Qbb priority-based flow control (PFC), 802.1Qaz enhanced transmission selection (ETS), and the data center bridging exchange (DCBX) protocol.
CLI commands for individual DCB features are as follows:
DCB commands
dcb enable auto-detect on-next-reload
dcb-map
dcb-policy input stack-unit stack-ports all
PFC Commands
clear pfc counters
show interface pfc
show interface pfc statistics
show stack-unit stack-ports pfc details
ETS Commands
clear ets counters
show interface ets
show stack-unit stack-ports ets details
qos-policy-output ets
DCBX Commands
dcbx version
show dcb
show interface dcbx detail

clear ets counters

Clear ETS TLV counters.
