In
this
configuration,
each
BladeCenter
T
unit
contains
two
Ethernet
switch
modules
and
one
management
module.
The
external
ports
on
the
switch
modules
are
configured
for
multiport
link
aggregation
groups,
or
trunks,
as
are
the
corresponding
ports
on
the
attached
external
LAN
switches.
Additionally,
every
port
in
the
switch
module
in

(switch

in

in
the
BladeCenter
T
units
is

to
the
same
external
LAN
switch,

in
the

(switch
B
in

in
the
BladeCenter
T
units
is
connected
to
another
external
LAN
switch.
Observe
the
following
guidelines
when
creating
this
topology:
1.
The
external
ports
on
the
BladeCenter
T
switch
modules
are
designed
for
point-to-point,
full-duplex
operation
to
a
compatible
LAN
switch
or
router.
Configure
a
corresponding
multiport
link
aggregation
group,
or
trunk,
in
both
the
switch
module
and
the
attached
LAN
switch
before
installing
the
cables.
The
connection
options
are
as
follows,
in
order
of
preference:
v
Multiport
link
aggregation
group
or
trunk,
1
Gbps
(1000
Mbps)
per
port
v
Single-uplink
port,
1
Gbps
v
Multiport
link
aggregation
group
or
trunk,
100
Mbps
per
port
2.
Connect
the
management-module
10/100
Mbps
Ethernet
port
to
a
separate
layer
2
network
for
security.
If
a
separate
network
is
not
available,
you
can
attach
the
Ethernet
ports
of
the
management
module
and
switch
modules
to
the
same
layer
2
network.
3.
Avoid
network
configurations
that
could
lead
to
data
loops,
if
possible.
Loops
will
be
created
if
you
connect
multiple
ports
from
the
same
switch
module
to
the
same
layer
2
network
device
without
first
enabling
link
aggregation.
