packet tracer activity basic switch and

anti device configuration before coming

to this activity first if you are

watching our channel first time or if

you like to get this type of technical

videos in future considered subscribing

also don't forget to enable that bill

icon near the subscribe button so that

you will get notification message

whenever we upload a new video also if

you need any technical support or any

help or if you like to get this packet

tracer activity file you can contact our

team using our website link I given in

the description now coming back to our

packet tracer activity here we can see

our a dressing-table devices such as

Class A Class B here we can see those

two switches also we can see two anti

devices to ten to one and their student

two here we can see IP address and

subnet to mask for each devices okay in

this activity we will configure house

names and IP addresses on to cisco

internetwork operating system switches

using the command-line interface then we

will use the Cisco IOS commands to

specify or a limit access to device

configurations also we will use iOS

commands to save the running

configuration then we will configure to

host devices with IP addresses and

finally we will verify connectivity

between these two pieces I mean with

these NT devices pure a recently hired

land technician your network manager has

asked you to demonstrate your ability to

configure a small land our tasks include

configuring initial settings on two

switches using the cisco is and

configuring IP address parameters on

house devices to provide end-to-end

connectivity so you are to use two

switches and two

house two pcs on a cable and pervert

network yes this is what we are going to

do in this packet tracer activity here

we can see the instructions configure

the devices to fulfill the requirements

below here we can see the requirements

use a console connection to access each

switch yes only we done basic

configurations also cancel connection

with our previous a packet tracer

activities

hence this packet tracer activity will

be more easy for us okay first of all we

will connect our switch using console

connection so coming to connections sure

we can see console we will let's select

the console then from switch class a we

will select console port to this student

PC student - 1 you will connect to

rs-232 same way we can connect class - B

switch to our PC student - - sure is our

console cable coming to class - B we

will connect to console port then in

student - - we will connect to rs-232

this connection is obviously for the

basic configuration of these network

devices so next is we are going to set

the hostname class - a and class - B -

these switches now we will access so

this switch class - a using this ng

device piece student - one so we will go

to student - one then we will go to the

stop and here we can see terminal then

click ok and here we can see now we are

in switch class - a we will set the

hostname we'll go to

privileged exit more and then we'll go

to global configuration mode enable

configure terminal press enter so here

we are going to set the hostname as

class - a then press Enter

and here we can see that change in this

prompt next we will go to a class -

beasts which we can access using this

entry device to run - - we'll go to

desktop terminal then ok let's enter

enable configure terminal here we are

going to set the hostname as + - b press

enter and here we can see that change it

is prompt next is a use the r4 xe3 so

this is the password for all lines that

means for a console as well as for VG

vine we will do that we will copy this

password we will let do in this class -

be okay sure first of all we will go to

line console 0 then we will set the

password here as specified it's here we

already copied that then we have to give

a login command now we will exit then we

will go to line vty 0 - we will give all

the lines from 0 to 15 we will give you

the password it's here also we will give

login

now we will go to class - a will go to

the center device or we close that

window so again we will go to terminal

ok here we will go to line console 0

then we will set the password it's here

you will exit and we will go to line vty

all the lines 0 to 15 password it's here

let's it next is they use this password

see for a J a a secret password okay so

we will copy this password we can see

it's the case sensitive it's for scoring

purpose first of all we will do it for

our switch class - a sure we will give

an enable secret and a hurry sort

password press enter now we will go to

you configure in a class - B enable

secret and here is the password know it

gripped all clear text passwords so we

know the command service password

encryption so we will give that here

Servais password encryption then press

enter now we will go to student to one

service password encryption then

configure an appropriate message of the

day that is M or TD banner okay that can

be done we have the commands BA in an ER

banner message of the day M our TD then

we have to give our

banner we will start with the delimiter

and authorized access is strictly

prohibited

presenter no we will do it on glass - be

coming to int device how terminal here

we will give banner motd then our

message warning and authorized access is

strictly prohibited any message right

next is configure addressing for all

devices for these four devices according

to our addressing table so here we can

see our addressing table so as per our

addressing table we are going to set IP

address for these devices first of all

may be the same IP address for this int

devices 2 n - 1

no addressing table we can see IP

address for this NT device we will copy

this address also we can see it's a SATA

mask coming to student 2 1 we will close

this terminal and we will go to IP

configuration and here in this IP

configuration we will give the IP

address then it's a subjective mask so

it's correct here we can see it took the

default something to mask but here we

can we can see they given something to

mask a slash 24 just you will copy this

and we will paste here so it's done now

we will have seen IP address for our

next gen 2 device so that is 2 n - 2 we

will close this a terminal then coming

to

IP configuration in our addressing table

here we can see IP address for this

device will copy and paste here and it's

something to mask it's done next we are

going to and say an IP address for these

devices class - a and class - B for the

interface vlan1 we will copy the IP

address of class - a then we will go to

a student - one terminal ok now we are

in a global configuration mode we have

to go to interface vlan1

and the here we are going to set the IP

address here is the IP address then be

something to mask then we have to give

an ocean command next we will do it on

class - be sure we can see IP address

coming to student - - we'll go to

terminal

ok and here we will go to the interface

vlan1

then we have to set the IP address as

per our dressing table it's here then

it's something to mask then we have to

give an ocean command so we are saying

IP address for all the devices next to

be able to save our configurations we

can do that we will press control sir

the so that we can go to privileged x ik

mode then press Enter here we are going

to copy our u n tab st tab press ENTER

ok now we will go to student that - to

control third presenter copy

running-config startup-config okay

finally we are going to verify a

connectivity between all devices okay we

will ping from student - one - this in

device - run - - you will get the IP

address of a student - - it's your we

will copy that

coming to student - one we will go to

command prompt it's working

sure they're given and not click check

results to see your progress click reset

activity to generate a new set of

requirements if you click on this before

you complete the activity all

configurations will be lost so whenever

you open you may get different

requirements maybe this hostname made

changes or password changes there will

be some number of devices we have to do

all these basic configurations nothing

else here in this activity we can see

our completion status is hundred

percentage and in this activity we have

seen a basic switch and the entry device

configuration now dear friends if you

have any doubt any suggestions please

comment below also if you liked our

video give it thumb and share with all

your friends and if you like to contact

our team you can restore website a link
