Tab completion displays allowed properties only
There
are
some
important
principles
to
understand
when
using
tab
completion
for
object
properties:
•
The
properties
of
an
object
are
either
required
or
optional.
When
using
tab
completion,
optional
properties
are
not
displayed
until
all
required
properties
have
been
assigned
a
value.
•
An
optional
property’s
use
can
depend
on
the
value
specified
for
another
property.
For
example,
in
an
IPsecTunnel
object,
the
optional
ProxyARP
property
can
be
used
only
when
the
AddRouteToRemoteNetwork
property
has
been
set
to
Yes
.
The
tab
completion
feature
is
aware
of
these
dependencies
and
will
not
display
a
property
if
it
is
dependent
on
another
property
that
has
not
yet
been
assigned
a
value.
Looking
at
the
IPsecTunnel
example
again,
tab
completion
will
display
the
ProxyARP
property
only
if
the
AddRouteToRemoteNetwork
property
has
been
already
been
assigned
a
value
of
Yes
.
CLI help
The
CLI
help
command
will
show
all
available
command
options.
Typing
help
followed
by
a
command
name
will
show
help
information
for
that
command,
providing
details
about
the
command's
function
and
its
options.
For
example:
Device:/>
help
time
COMMAND
time
(t).
Display
and
set
current
system
time.
"
"
Typing
this
CLI
command
provides
information
about
the
help
command
itself:
Device:/>
help
help
Configuration object help
A
second
help
command,
helpconfig
,
provides
information
about
a
particular
object
type
or
category
of
objects.
CLI command history
Just
like
a
command
console
in
many
versions
of
Microsoft
Windows™,
the
up
and
down
arrow
keys
enable
you
to
move
through
the
list
of
commands
in
the
CLI
command
history
.
For
example,
pressing
the
up
arrow
key
once
will
make
the
last
command
executed
appear
at
the
current
CLI
prompt.
After
a
command
appears,
it
can
be
re
‐
executed
in
its
original
form
or
changed
first
before
execution.
