NE2552E Application Guide for ENOS 8.4
End User Access Control
Lenovo
ENOS
allows
an
administrator
to
define
end
user
accounts
that
permit
end
users
to
perform
operation
tasks
via
the
switch
CLI
commands.
Once
end
user
accounts
are
configured
and
enabled,
the
switch
requires
username/password
authentication.
For
example,
an
administrator
can
assign
a
user,
who
can
then
log
into
the
switch
and
perform
operational
commands
(effective
only
until
the
next
switch
reboot).
Considerations for Configuring End User Accounts
A
maximum
of
20
user
IDs
are
supported
on
the
switch.
Lenovo
ENOS
supports
end
user
support
for
Console,
Telnet,
BBI,
and
SSHv1/v2
access
to
the
switch.
If
RADIUS
authentication
is
used,
the
user
password
on
the
Radius
server
will
override
the
user
password
on
the
NE2552E.
Also
note
that
the
password
change
command
modifies
only
the
user
switch
password
on
the
switch
and
has
no
effect
on
the
user
password
on
the
Radius
server.
Radius
authentication
and
user
password
cannot
be
used
concurrently
to
access
the
switch.
Passwords
can
be
up
to
64
characters
in
length
for
Telnet,
SSH,
Console,
and
Web
access.
Strong Passwords
The
administrator
can
require
use
of
Strong
Passwords
for
users
to
access
the
NE2552E.
Strong
Passwords
enhance
security
because
they
make
password
guessing
more
difficult.
The
following
rules
apply
when
Strong
Passwords
are
enabled:
Minimum
length:
8
characters;
maximum
length:
64
characters
Must
contain
at
least
one
uppercase
alphabet
Must
contain
at
least
one
lowercase
alphabet
Must
contain
at
least
one
number
Must
contain
at
least
one
special
character:
Supported
special
characters:

Cannot
be
same
as
the
username
When
strong
password
is
enabled,
users
can
still
access
the
switch
using
the
old
password
but
will
be
advised
to
change
to
a
strong
password
while
attempting
to
log
in.
The
strong
password
requirement
can
be
enabled
using
the
following
command:
NE2552E(config)#
access user strong-password enable
