hey welcome back i'm sean barnett
looking point we help it organizations
make decisions around collaboration
security and networking today we're
talking about a cisco 9200 series switch
and how to reset the password for those
of you that want to get right into it
don't care about all the gory details
i'll just give you a rundown you're
gonna power up the switch with a console
connected as soon as you power it up
there's gonna be some blinky lights over
here on the right hand side of the
switch you're gonna press this button a
few times it's going to bring you into
the boot loader once there you're going
to tell it to ignore the configuration
and you're going to boot it from flash
once the switch boots up you can get
into enable configuration mode and reset
the password you'll reset the device
again press the mode button again and
tell it to pay attention to the
configuration that's a quick and dirty
on how to reset the password we're going
to go into all the details right after
this let's go
[Music]
all right we're back and we're going to
be resetting a password on a cisco 9200
series switch
in order to do that we need a couple
things we need a console cable which i
have here it's a usb
to console server or usb to console port
actually and then i've connected a cisco
rollover cable which connects to the
back of the switch in the console port
now modern day laptops they have usbc
connections so i have a usbc two usb
port then i've got the usb
console server then our console
connection console cable whatever you
want to call it and then i've got the
cisco rollover cable which goes to the
back of the console port
there's another option which is to use a
usb cable to the back of the switch and
plug it directly into your laptop i
prefer a traditional usb port so
in order to get started what we're going
to do is we're going to power up the
switch as soon as i see some blanky
lights here i'm going to tap this grey
button here on the front of the switch a
number of times it's going to drop us
into boot mode i'm going to issue some
commands and you'll see that on the
screen recording once that happens i'm
going to reboot the switch again and
it's going to or i'm going to continue
booting the switch and then i'm going to
reset the password i'm going to reboot
it again tell it to pay attention to the
configuration but i'll have access to
the switch so let's get started so the
first thing i'm going to do is i'm going
to connect
the
port here
or the power
and we're going to flip over to my
console port which it should start
showing it initializing the switch which
we see i'm going to see some blinky
lights here and i'm just going to press
this button a couple of times as it's
going
and really
what i've noticed through this is the
time to really press it is after it's
kind of it says its current rom on image
and tells you about that i'm going to
press it keep pressing it and then it's
going to eventually drop us in the
switch config
all right
so it's drop descended switch config and
the first thing i'm going to do these
commands we're going to be doing a
setting or we're going to be setting a
setting and the settings themselves are
case sensitive
so if you type them in lowercase they
will not work so we're going to type
switch
underscore ignore
underscore
startup
underscore cfg
equals one
and that is going to tell it to ignore
the switch config and then i can type
just in normal case boot flash
colon packages
[Music]
and it'll start loading so this is going
to take a few minutes and we will cut to
when it finally boots up all right so
now we're here where our switch is
booted up and we've told it to ignore
the configuration i'm going to hit
return
and it's going to bring me right into
the switch prompt so you'll see it
didn't prompt me for any type of
authentication that's because our
command that we put on the switch told
it to ignore the configuration so this
switch in theory well right now it does
not have a configuration loaded on it so
i'm going to type enable
and then i'm going to
i can do two things one is i can copy
the startup configuration to the running
configuration and if i do that it'll
pull back the config that's stored here
and i could reset the password so in my
case i really don't care about the
configuration so i really don't want to
care to see it but for the example i
will i'll actually pull the config in so
if you're trying to save your config you
could see that but if you didn't really
care about the configuration on it you
could just write the configuration right
now as is and it would default the
configuration you could do that
but what i'm going to do is i'm going to
type copy
startup
config to running config and what that's
going to do is copy the startup
configuration that's saved on the on the
flash here and it's going to pull it
into the running so what we're going to
see is it's going to load all the
configurations and syntax and it's going
to ask me the destination name i'm going
to hit return and it's going to do some
things here and we'll probably see some
some stuff and you'll see that i'm in ph
switch 6. and so
now i could actually set the enable
password um i'm going to just do a
configuration mode put it in conf in
configuration mode i'm going to
configure username
i'm going to configure
cisco
privilege level 15
and a secret password of cisco
and hit enter and then i'm going to type
enable
secret
cisco
and that's going to set my to login my
create a user account and password of
cisco cisco and it created the secret of
cisco
and so now i'm going to
write my configuration
and now what i'll do is reboot the
switch press the mode button again to
get back into the configuration mode and
tell it to
not ignore the startup config so i'm
going to unplug it
and we're gonna plug it back in and wait
for the mode button
see some blinky lights
and i'll be watching the
console over here and once i see an
indication that it's loading i'm going
to start pressing the mode button now
what there's a lot of instructions out
there that tell you you got to press the
mode button right away
you're going to see it boot up so it's
not instantaneously that you're pushing
the mode button it's just you'll see it
pop up in the console and you'll start
pressing it and you'll be in good shape
and so right now i'm not even pressing
the mode button now i'm going to press
it
and it dropped me into the switch config
so you saw that there was i don't know
15 20 seconds of time where i was just
waiting to press the mode button and now
i did and now i'm in the switch mode so
again uh this this portion is going to
take
all caps i'm going to say switch
underscore ignore
underscore startup
underscore cfg
equals zero so this is saying
don't
ignore the start of config
and i'm going to type
[Music]
and it's going to be booting and we'll
come back once it's booted up okay so
now the switch is loaded we've told it
to pay attention to the config and it's
telling me return press return to start
so i'm going to press return and it
should prompt me with the username and
we reset ours to cisco
and we set the password to cisco
and here we are we're logged into the
switch and if i type enable we reset the
enable password to cisco and you can see
i logged into the switch so we've
successfully saved the config on the
switch
and reset the username and password so
we have access
to it
to do whatever we need to do
okay so to recap what we did here we got
a console cable we put it into the
console port we powered on the switch we
waited for it to get to the loader
or start booting up the switch and we'll
see that on our console and then we will
tap the button here on the front of the
switch that'll drop us into the switch
bootloader from there we need to make
sure when we set the command to ignore
the configuration that is case sensitive
so we need to make sure that that's all
in uppercase we set that and then we
tell it to continue booting it will
ignore the configuration on that first
boot we go in and copy the startup
config to the running config once we're
at that point we will change the
passwords create a username whatever you
need to do for your particular
configuration in our case we set a
username and password and also set the
enable password
then we are going to save that
configuration reboot go back into the
bootloader tell it to pay attention to
the startup config let it continue to
boot and then we were able to log in
with the switch
so
back to the console port this is a 9600
baud
is the standard console speed for a
console port we just used like i said a
usb to console cable we're using secure
crt as the console um emulator so that
we can get access to the console port
there's a ton of them out there
and those are the key things it's
console and power pretty simple if i
said anything in this video that you're
like hey i'd love to know more about
that make sure you leave a comment make
sure you like and subscribe so you get
