16 About this Guide
Before You Start
To install the Aggregator in a Dell PowerEdge M1000e Enclosure, use the instructions in the Dell PowerEdge M I/O Aggregator Getting
Started Guide that is shipped with the product.The I/O Aggregator (also known as Aggregator) installs with zero-touch conguration. After
you power it on, an Aggregator boots up with default settings and auto-congures with software features enabled. This chapter describes
the default settings and software features that are automatically congured at startup. To recongure the Aggregator for customized
network operation, use the tasks described in the other chapters.
Operational Modes
IOA 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
CONFIGURATION mode
Dell(conf)#stack-unit 0 iom-mode standalone
This mode is the default mode for IOA. It is a fully automated zero-touch mode that allows you to congure VLAN memberships.
(Supported in CMC)
VLT mode
stack-unit unit iom-mode vlt
CONFIGURATION mode
Dell(conf)#stack-unit 0 iom-mode vlt
Select this mode to multihome server interfaces to dierent IOA modules. This mode is a low-touch mode where all conguration except
VLAN membership is automated. To enable VLAN, congure the VLANs at the server port level. In this mode, port 9 link, which is
associated with LAG-127, is dedicated to VLT interconnect.
Programmable MUX mode
stack-unit unit iom-mode programmable-mux
CONFIGURATION mode
Dell(conf)#stack-unit 0 iom-mode programmable-mux
Select this mode to congure PMUX mode CLI commands.

Stacking mode
stack-unit unit iom-mode stack
CONFIGURATION mode
Dell(conf)#stack-unit 0 iom-mode stack
Select this mode to congure Stacking mode CLI commands.
For more information on the Stacking mode, see Stacking.
Default Settings
The I/O Aggregator provides zero-touch conguration with the following default conguration settings:
• default user name (root)
• password (calvin)
• VLAN (vlan1) and IP address for in-band management (DHCP)
• IP address for out-of-band (OOB) management (DHCP)
• read-only SNMP community name (public)
• broadcast storm control (enabled in Standalone mode and disabled in VLT mode)
• IGMP multicast ooding (enabled)
• VLAN conguration (in Standalone mode, 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 congure the aggregator, refer to the
Dell Chassis Management Controller (CMC)
User’s Guide

Other Auto-Congured Settings
After the Aggregator powers on, it auto-congures and is operational with software features enabled, including:
• Ports: Ports are administratively up and auto-congured to operate as hybrid ports to transmit tagged and untagged VLAN trac.
Ports 1 to 32 are internal server-facing ports, which can operate in 10GbE mode. Ports 33 to 56 are external ports auto-congured to
operate by default as follows:
– The base-module ports operate in standalone 4x10GbE mode. You can congure these ports to operate in 40GbE stacking mode.
When congured for stacking, you cannot use 40GbE base-module ports for uplinks.
– Ports on the 2-Port 40-GbE QSFP+ module operate only in 4x10GbE mode. You cannot use them for stacking.
– Ports on the 4-Port 10-GbE SFP+ and 4-Port 10GBASE-T modules operate only in 10GbE mode.
For more information about how ports are numbered, refer to Port Numbering.
• Link aggregation: All uplink ports are congured in a single LAG (LAG 128).
• VLANs: All ports are congured as members of all (4094) VLANs. All VLANs are up and can send or receive layer 2 trac. For more
information, refer to VLAN Membership.
• Data center bridging capability exchange protocol (DCBx): Server-facing ports auto-congure in auto-downstream port roles; uplink
ports auto-congure in auto-upstream port roles.
• Fibre Channel over Ethernet (FCoE) connectivity and FCoE initiation protocol (FIP) snooping: The uplink port channel (LAG 128) is
enabled to operate in Fibre channel forwarder (FCF) port mode.
18
Before You Start
• Link layer discovery protocol (LLDP): Enabled on all ports to advertise management TLV and system name with neighboring devices.
• Internet small computer system interface (iSCSI)optimization.
• Internet group management protocol (IGMP) snooping.
• Jumbo frames: Ports are set to a maximum MTU of 12,000 bytes by default.
• Link tracking: Uplink-state group 1 is automatically congured. In uplink state-group 1, server-facing ports auto-congure as
downstream interfaces; the uplink port-channel (LAG 128) auto-congures as an upstream interface. Server-facing links are auto-
congured to be brought up only if the uplink port-channel is up.
• In VLT mode, port 9 is automatically congured as VLT interconnect ports. VLT domain conguration is automatic. This includes peer-
link, congured MAC, backup link and setting every port channel as VLT port-channel.
Data Center Bridging Support
To eliminate packet loss and provision links with required bandwidth, Data Center Bridging (DCB) enhancements for data center networks
are supported.
The aggregator provides zero-touch conguration for DCB. The aggregator auto-congures DCBX port roles as follows:
• Server-facing ports are congured as auto-downstream interfaces.
• Uplink ports are congured as auto-upstream interfaces.
In operation, DCBx auto-congures uplink ports to match the DCB conguration in the ToR switches to which they connect.
The Aggregator supports DCB only in standalone mode.
FCoE Connectivity and FIP Snooping
Many data centers use Fiber Channel (FC) in storage area networks (SANs). Fiber Channel over Ethernet (FCoE) encapsulates Fiber
Channel frames over Ethernet networks.
On an Aggregator, the internal ports support FCoE connectivity and connects to the converged network adapter (CNA) in servers. FCoE
allows Fiber Channel to use 10-Gigabit Ethernet networks while preserving the Fiber Channel protocol.
The Aggregator also provides zero-touch conguration for FCoE connectivity. The Aggregator auto-congures to match the FCoE settings
used in the switches to which it connects through its uplink ports.
FIP snooping is automatically congured on an Aggregator. The auto-congured port channel (LAG 128) operates in FCF port mode.
iSCSI Operation
Support for iSCSI trac is turned on by default when the Aggregator powers up. No conguration is required.
When an 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 autocongures to optimize performance. Performance optimization
operations, such as Jumbo frame size support and disabling storm control on interfaces connected to an iSCSI equallogic (EQL) storage
device, are applied automatically.
Link Aggregation
All uplink ports are congured in a single LAG (LAG 128). Server-facing ports are auto-congured as part of link aggregation groups if the
corresponding server is congured for LACP-based network interface controller (NIC) teaming. Static LAGs are not supported.
NOTE
: The recommended LACP timeout is Long-Timeout mode.
Before You Start 19
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 after the specied defer-timer interval, which is
10 seconds by default. If you have congured VLAN, you can reduce the defer time by changing the defer-timer value or remove it by using
the no defer-timer command.
NOTE: If installed servers do not have connectivity to a switch, check the Link Status LED of uplink ports on the aggregator. If all
LEDs are on, to ensure the LACP is correctly congured, check the LACP conguration on the ToR switch that is connected to
the aggregator .
Conguring VLANs
By default, in Standalone mode, all aggregator ports belong to all 4094 VLANs and are members of untagged VLAN 1. To congure only the
required VLANs on a port, use the CLI or CMC interface.
You can congure VLANs only on server ports. The uplink LAG will automatically get the VLANs, based on the server ports VLAN
conguration.
When you congure VLANs on server-facing interfaces (ports from 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 Conguration mode; for example:
Dell(conf)# interface range 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
Uplink LAG
The tagged VLAN membership of the uplink LAG is automatically congured based on the VLAN conguration of all server-facing ports
(ports from 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 congured based on the server-facing ports that are members of
the LAG.
The untagged VLAN of a server-facing LAG is congured based on the untagged VLAN to which the lowest numbered server-facing port
in the LAG belongs.
NOTE
: Dell Networking recommends conguring the same VLAN membership on all LAG member ports.
Where to Go From Here
You can customize the Aggregator for use in your data center network as necessary. To perform additional switch conguration, 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 IP address of the default VLAN and log in to the
switch to access the CLI.
