Lenovo ThinkSystem NE2552E Flex Switch: Installation Guide
When
configuring
the
switch,
you
must
execute
the
copy
running-config
startup-config
command
if
you
want
the
configuration
change
to
persist
beyond
the
next
reboot
of
the
switch.
This
command
stores
the
current
switch
configuration
and
all
changes
in
nonvolatile
memory.
If
the
switch
restarts
and
the
CMM
cannot
apply
the
saved
configuration,
the
switch
defaults
to
the
configuration
that
was
previously
saved.
If
the
IP
subnet
address
of
the
switch
does
not
match
the
IP
subnet
address
of
the
CMM,
you
can
no
longer
manage
the
switch
from
the
CMM.
For
more
information
about
configuring
the
switch,
see
the
Command
Reference
for
your
specific
switch
and
its
installed
firmware.
When
you
use
the
management
‐
module
Web
interface
to
update
the
switch
configuration,
the
management
‐
module
firmware
saves
the
new
configuration
in
internal
nonvolatile
memory.
If
the
switch
restarts,
the
CMM
applies
the
saved
configuration
to
the
switch.
For
more
information,
see
the
Application
Guide
and
the
Command
Reference
for
your
specific
switch
and
its
installed
firmware.
For
switch
communication
with
a
remote
management
station,
such
as
an
Lenovo
Director
management
server,
through
the
management
‐
module
external
Ethernet
port,
the
switch
internal
‐
network
interface
and
the
management
‐
module
external
interface
must
be
on
the
same
IP
subnet.
For
specific
details
about
configuring
the
switch
and
preparing
for
system
installation,
see
the
documentation
listed
in
.
