Enabling Management Through Data Ports
To
access
and
manage
the
switch
through
external
interfaces,
you
must
enable
the

and
the
ability
to
manage
the
switch
through
them.
Use
the

complete
the
following
steps:
1.

described
in
the
CMM
documentation.
If
necessary,
obtain
the
IP
address
of
the
CMM
from
your
system
administrator.
2.
Set
the
environment
to
the
bay
where
you
installed
the
switch:
3.
Execute
the
ifconfig

to
enable
data
