Telnet
with
CLI
A
command
‐
line
interface
(CLI),
also
known
as
command
‐
line
user
interface,
and
console
user
interface
are
means
of
interacting
with
a
computer
program
where
the
user
(or
client)
issues
commands
to
the
program
in
the
form
of
successive
lines
of
text
(command
lines).
The
interface
is
usually
implemented
with
a
command
line
shell,
which
is
a
program
that
accepts
commands
as
text
input
and
converts
commands
to
appropriate
operating
system
functions.
Programs
with
command
‐
line
interfaces
are
generally
easier
to
automate
via
scripting.
The
device
supports
both
Telnet
and
SSH
(Secure
Shell)
CLI
with
default
service
port
23
and
22,
respectively.
