Configuring
the
switch
module
through
the
Telnet
interface
The
switch
module
contains
a
Telnet
server.
This
server
enables
a
Telnet
client
to
establish
a
Telnet
session
with
the
Fibre
Channel
switch
module
to
retrieve
information
or
to
configure
parameters
through
the
command-line
interface
(CLI).
You
can
perform
a
variety
of
fabric
and
switch-management
tasks
through
an
Ethernet
connection
by
using
the
CLI.
You
can
access
the
Telnet
interface
in
two
ways:
v
In
the
BladeCenter
unit
management-module
Web
interface
v
In
a
command-line
window
on
a
network-management
workstation
For
you
to
configure
the
switch
module
through
the
Web
interface,
the
Internet
protocol
(IP)
address
and
subnet
masks
must
be
compatible,
and
the
following
configuration
settings
in
the
management
module
must
be
enabled:
v
Switch-module
external
ports
v
External
management
for
external
ports
To
access
a
switch
module
from
a
network-management
workstation,
make
sure
that
it
is
connected
to
an
external
BladeCenter
unit
management-module
Ethernet
port.
To
enable
the
configuration
settings
in
the
management-module
Web
interface,
click
I/O
Module
Tasks
→
Admin/Power/Restart
.
Important:
Before
configuring
the
switch
module,
make
sure
that
the
management
modules
in
the
BladeCenter
unit
are
correctly
configured.
In
addition,
to
access
and
manage
the
switch
module
from
an
external
environment,
you
might
have
to
enable
certain
features,
such
as
the
external
ports
and
external
management
over
all
ports.
See
the
Installation
and
User’s
Guide
for
the
BladeCenter
unit
for
more
information.
