Product Description
The MXL 10/40GbE Switch is a layer 2/3 blade switch with two fixed 40GbE
ports on the base module and support for two optional plug-in modules. The
switch operates in a PowerEdge M1000e Enclosure, which can support up to
32 servers and six MXL 10/40GbE Switches.
The MXL 10/40GbE Switch runs the Force10 Operating System (FTOS),
providing switching, bridging, and routing functionality for transmitting data,
storage, and server traffic as follows:
•GbE/10GbE connections through the midplane to up to 32 server ports in
the chassis
•GbE, 10GbE or 40GbE connections through uplink ports to top-of-rack
(ToR) switches
•40GbE stacking connections to other
switch stack
In a data center network, the MXL 10/40GbE Switch provides converged
network support and interoperates with Dell and third-party ToR devices.
The switch supports
connectivity between servers and storage devices over Fiber Channel over
Ethernet (FCoE) and iSCSI links.
By providing increased 40GbE bandwidth for device interconnection in a
shared network storage environment, with the possibility of splitting 40GbE
QSFP+ uplinks into 10GbE SFP+ connections, the MXL 10/40GbE Switch
is perfectly positioned to help transition a data center with multiple speed
requirements.

Internal Ports
The MXL 10/40GbE Switch provides 32 1/10-Gigabit Ethernet internal ports.
The internal ports are connected to server blades through the M1000e chassis
midplane. Each port can operate in either 1GbE or 10GbE mode. Internal
ports are numbered 1 to 32.
The MXL 10/40GbE Switch also provides an internal Ethernet interface—the
out-of-band (OOB) interface—which is dedicated to switch management.
The OOB interface is connected to the chassis management controller
(CMC) through the chassis midplane. Traffic on this port is segregated from
operational network traffic on the switch ports and cannot be switched or
routed to the operational network.

Base Module
The MXL 10/40GbE Switch provides two native 40-Gigabit Ethernet fixed ports
on the base module for uplink connections. You can use these ports with 4x10G
breakout cables to operate as 10GbE uplink ports.
In addition, you can configure the native 40GbE ports as stacking ports. You
can connect up to six MXL 10/40GbE Switches (in the same or different
chassis) in a single stack. For more information, refer to "Assembling a Switch
Stack" on page 25.
FlexIOTM Plug-in Modules
The MXL 10/40GbE Switch (Figure 1-2) provides 10/40GbE external
connectivity by using the following FlexIO plug-in modules in the two
expansion slots:
•4-Port 10-Gigabit Ethernet module using SFP+ optics (SR or LR) or
direct-attach cables (1m, 3m, or 5m DAC)
•4-Port 10GBASE-T module using RJ-45 connector (copper) cables
NOTE: The 10Mb speed is not supported on the 4-Port 10GBASE-T module.
Only 100Mb, 1GbE, and 10GbE speeds are supported.
•2-Port 40-Gigabit Ethernet quad form-factor pluggable plus (QSFP+)
module which you can use for 40GbE connections or 10GbE small formfactor pluggable plus (SFP+) connections using 4x10G breakout cables.
By default, the 40GbE ports on a 2-Port 40GbE QSFP+ module come up
in 4x10GbE (quad) mode as eight 10GbE ports. To change a port from
4x10GbE to 40GbE mode of operation, enter the

NOTE: You can only hot-swap plug-in modules of the same type without requiring a
reboot. For example, you can replace a 2-Port 40GbE QSFP+ module only with
another 2-Port 40GbE QSFP+ module.
On the MXL 10/40GbE Switch, you can configure uplink ports of the same
speed on different modules in the same link aggregation group (LAG). You
can also use individual ports for uplink connections.
NOTE: A maximum of 16 ports are supported in a LAG.
For switch stacking, you must use a 40GbE port on the base module or on a
2-Port 40GbE QSFP+ plug-in module. Stacking is not supported on 10GbE
ports.
All FlexIO plug-in modules, transceivers, and attach cables are sold separately.

Assembling a Switch Stack
After you complete the initial switch configuration, the MXL 10/40GbE
Switch is powered up and operational. Stacking is supported on the 40GbE
ports on the base module or a 2-Port 40GbE QSFP+ module to connect up
to six MXL 10/40GbE Switches in a single stack.
Figure 1-9 shows an example using six MXL 10/40GbE Switches in a chassis.
The MXL 10/40GbE Switches are connected to operate as a single stack in a
ring topology using only the 40GbE ports on the base modules. You can use
the 40GbE ports on the base module and plug-in modules to create a stack in
either a ring or daisy-chain topology.
NOTE: All MXL 10/40GbE Switches in the stack should be powered up with the
initial configuration before you attach the cables.

On the leftmost switch, connect the bottom stacking port to the upper
stacking port on the rightmost switch to create a loop.
NOTE: The resulting ring topology allows the entire stack to function as a single
switch with resilient fail-over capabilities.
If you do not connect the leftmost switch to the rightmost switch (Step 4), the stack
operates in a daisy-chain topology with less resiliency. Any failure in a non-edge
stack unit causes a split stack.
Configuring and Bringing Up a Stack
NOTE: Although stacking is supported on 40GbE ports on the base module or a
2-Port 40GbE QSFP+ module, this section shows how to configure stacking only on
the base-module ports (Figure 1-9).
To convert the 40GbE ports on the 2-Port QSFP+ module from their default 4x10GbE
mode of operation to 40GbE mode to configure a stack, refer to "FlexIOTM Plug-in
Modules" on page 7. After the converting the ports to 40GbE, you do not have to
reload the switch because a switch reload is required as part of the stack
configuration procedure.
After you attach the QSFP+ cables in a stack of MXL 10/40GbE Switches, to
configure and bring up the stack, follow these steps:
1
Connect the terminal to the console port on an
Enter the following commands to access the CLI and configure the two
40GbE ports on the base module for stacking mode:

in the stack by
commands and saving the configuration.
4
Reboot each switch by entering the reload command in EXEC Privilege
mode:
FTOS# reload
If the stacked switches all reboot at approximately the same time, the
switch with the highest MAC address is
automatically elected
as the
Master Switch. The switch with the next highest MAC address is elected
as Standby Master.
To configure the stack so that the roles are assigned according to
pre-determined priorities, enter the
stack-unit priority
command as
described in the Note below.
To reload the stack, connect the terminal to the Master Switch and enter the
reload command in EXEC Privilege mode. If you connect the terminal to a
member (non-Master) switch, you will not be able to access the CLI.
To determine which switch is the Stack Master, enter the show system
command at the terminal.
To remove a port from stacking mode, use the no form of the
group
command; for example, no stack-unit 0 stack-group 0. After entering the
stack-unit stack-
command, save the configuration and reload the switch for the change to take
effect. When the reload completes, the port comes up in 40GbE mode if it is
on the base module and in
4x10GbE (quad) mode if the port is on a plug-in
module.
NOTE: You can also manually configure the switch that will be master by entering
the stack-unit

Managing a Stack
Master and Member Switches
You can manage a stack of MXL 10/40GbE Switches as a single entity when
connected together. Manage the stack from the CLI through the serial
console connection or a remote Telnet session over the OOB management IP
address.
When a stack is created, one switch automatically becomes the Master
Switch and another switch is elected Standby Master. The Master Switch
maintains stack operation with minimal impact in the event of:
•Switch failure
•Inter-switch stacking link failure
•Switch insertion
•Switch removal
If the Master Switch goes off line, the Standby Master replaces it as the new
master and the switch with the next highest MAC address or priority becomes
Standby Master.
Stack Startup
Topology Discovery
When a stack is formed, a topology discovery process builds up a database
that contains information about all of the switches in the stack, including the
FTOS version, hardware version, management priority, and switch MAC
address. Use the CLI (show system command) to view this information.
28Assembling a Switch Stack
Page 29
Auto Stack Number Assignment
During the stack formation process, a unique stack-unit number is assigned if
the same number is assigned to more than one switch. After assignment is
complete, each switch saves its stack-unit number. To view stack-unit
numbers, enter the show system command.
FTOS Version Checking
Following the stack-unit number assignment, the Master Switch performs a
consistency check to make sure that all switches in the stack are running the
same FTOS version.
If the Master Switch determines that all switches are not running the same
FTOS version, the ports on switches with the incorrect version are disabled.
To download the required FTOS image from the Master Switch and reload a
member switch so that it joins the stack, enter the following command in
EXEC Privilege mode:
FTOS# upgrade system stack-unit unit-numberpartition
Where stack-unitunit-number identifies the switch whose FTOS version
needs to be upgraded; partition identifies the partition on the Master Switch
from which the FTOS image boots up. For example:
FTOS# upgrade system stack-unit 3 a:
To display the boot partition used on the Master Switch, enter the show
version command.
To ensure that a stack unit boots from partition a:, enter the commands:
FTOS# configure
FTOS(conf)# boot system stack-unit unit-number primary system
a:
FTOS(conf)# end
FTOS# write memory
FTOS# power-cycle stack-unit
unit-number
NOTE: When an MXL 10/40GbE Switch is stacked, booting is supported only from
flash memory; it is not supported over the network via an IP address.
NOTE: To upgrade all switches in a stack with the same FTOS version in a specified
partition, enter the following command in EXEC Privilege mode:
FTOS# upgrade system {ftp: | tftp:}
This command uses an interactive CLI that requests the server IP address and
image filename, and prompts you to upgrade all member stack units. After
partition
Assembling a Switch Stack29

upgrading all switches in the stack, save the configuration (using the write memory
command) and reload the stack to activate the new FTOS version (using the reload
command).
System Initialization
The Master Switch initializes the stack using the last saved system
configuration file.
If you change the stack configuration, be sure to save the configuration file.
The Master Switch automatically distributes the configuration file to the
member switches. If the Master Switch later becomes unavailable, the
Standby Master becomes the new Master Switch and configures the stack
with the latest configuration synchronized from the Master Switch.
In case of a split stack in which the Master Switch in one of the new stacks
was previously a member switch, the last saved configuration on the original
stack is used to configure the new stack.
Splitting 40GbE QSFP+ Ports into
10GbE SFP+ Ports
The MXL 10/40GbE Switch supports splitting a 40GbE port on the base
module or a 2-Port 40GbE QSFP+ module into four 10GbE SFP+ ports
using a 4x10G breakout cable.
NOTE: By default, the 40GbE ports on a 2-Port 40GbE QSFP+ module come up in
4x10GbE (quad) mode as eight 10GbE ports. On the base module, you must convert
the 40GbE ports to 4x10GbE mode as described below.
Before you attach a 4x10G breakout cable to a 40GbE QSFP+ port, ensure
that the following requirements are met:
•A 4x10GbE QSFP+ port cannot be used for stacking.
•In order for a 40GbE port to operate in 4x10GbE mode, you must enter
the

Switch Configuration
After you complete the initial switch configuration, the MXL 10/40GbE
Switch is operational. You must manually configure the switch to enable
software features, such as:
•Data Center Bridging Capability Exchange Protocol (DCBX)
•Fiber Channel over Ethernet (FCoE) connectivity
•FCoE Initiation Protocol (FIP) snooping
•iSCSI optimization
•IGMP snooping
•RADIUS support
•TACACS+ client

iSCSI Operation
Support for iSCSI traffic is turned on by default when the MXL 10/40GbE
Switch powers up.
The MXL 10/40GbE Switch monitors known TCP ports for iSCSI
sessions.When a session is detected, an entry is created and monitored as long
as the session is active.
The MXL 10/40GbE Switch also detects EqualLogic 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 EqualLogic
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.
