The
bonding
function
enables
two
Ethernet
ports
to
operate
as
failover
devices
for
each
other.
v
If
you
are
using
the
AIX
operating
system,
the
Ether
Channel
device
driver
performs
the
bonding
function.
For
additional
information,
see
the
documentation
that
comes
with
your
operating
system.
v
If
you
are
using
one
of
the
Linux
operating
systems,
the
bonding
function
also
enables
two
Ethernet
ports
to
operate
as
one
Ethernet
port
with
twice
as
much
throughput
as
two
individual
Ethernet
ports.
To
use
the
bonding
function
for
Ethernet
ports
through
the
Linux
operating
systems,
you
must
use
the
bonding
device
driver
(for
Linux)
that
comes
with
your
operating
system.
Do
not
use
the
bonding
device
driver
that
comes
with
other
blade
servers.
For
additional
information
about
the
bonding
device
driver
for
Linux,
go
to
the
Linux
on
POWER
Web
site
at
http://techsupport.services.ibm.com/server/lopdiags/.
Depending
on
the
operating
system
that
you
installed,
click
the
SUSE
LINUX
or
Red
Hat
tab.
Then,
select
the
applicable
readme
file
from
the
list
of
files
under
the
Supporting
information
heading
in
the
right
navigation
column.
Review
the
contents
of
this
readme
file
for
instructions.
You
do
not
have
to
set
any
jumpers
or
configure
the
controllers
for
the
blade
server
operating
system.
However,
you
must
install
a
device
driver
to
enable
the
blade
server
operating
system
to
address
the
Ethernet-controller
ports.
For
device
drivers
and
information
about
configuring
your
Ethernet-controller
ports,
see
the
Ethernet
software
documentation
that
comes
with
your
blade
server,
or
contact
your
IBM
marketing
representative
or
authorized
reseller.
For
updated
information
about
configuring
the
controllers,
go

Support
Web

Blade
server
Ethernet
controller
enumeration
The
enumeration
of
the
Ethernet
controllers
or
controller
ports
in
a
blade
server
is
operating-system
dependent.
You
can
verify
the
Ethernet
controller
or
controller
port
designations
that
a
blade
server
uses
through
your
operating-system
settings.
The
routing
of
an
Ethernet
controller
or
controller
port
to
a
particular
BladeCenter
unit
I/O
bay
depends
on
the
type
of
Ethernet
expansion
card
that
is
installed.
You
can
verify
which
Ethernet-controller
port
in
this
blade
server
is
routed
to
which
I/O
bay
by
using
the
following
test:
1.
Install
only
one
Ethernet
switch
module
or
pass-thru
module,
in
I/O
bay
1.
2.
Make
sure
that
the
ports
on
the
switch
module
or
pass-thru
module
are
enabled
(
Switch
Tasks
→
Management
→
Advanced
Switch
Management
in
the
BladeCenter
management-module
Web
interface).
3.
Enable
only
one
of
the
Ethernet-controller
ports
on
the
blade
server.
Note
the
designation
that
the
blade
server
operating
system
has
for
the
controller
port.
4.
Ping
an
external
computer
on
the
network
connected
to
the
Ethernet
switch
module.
If
you
can
ping
the
external
computer,
the
Ethernet-controller
port
that
you
enabled
is
associated
with
the
switch
module
in
I/O
bay
1.
The
other
Ethernet-controller
port
in
the
blade
server
is
associated
with
the
switch
module
in
I/O
bay
2.
Communications
from
optional
Ethernet
adapters
and
other
I/O
expansion
cards
are
routed
to
I/O
bays
3
and
4.
You
can
verify
which
controller
port
on
an
expansion
card
is
routed
to
which
I/O
bay
by
performing
the
same
test,
using
a
controller
on
the
expansion
card
and
a
compatible
switch
module
or
pass-thru
module
in
I/O
bay
