Hello friends my name is Vasu Birla and today will discuss third method or idea on which we can divide IP address types. So Let’s start … in previous part we have discussed two methods already   now third method is here  3. Public and Private IP address    Public IP address -    When Classful addresses were introduced , IANA   made available IP address of three classes A B and C   for public  Means these IP addresses  -   Class A   begins 1 to 126   for government   or very big organizations                                                Class B begins 128 to 191   available   for medium size companies         ...

WHAT IS IP ADDRESS ?    Hello friends my name is Vasu Birla and today we will discuss about the IP address so let’s start. Ip address is a address through which we can identify a particular system within the network. IT is a unique identifier. And those systems who follows TCP/IP protocol uses this IP address. IP structure IP address is also known as Logical address. IT is made of 32 bit   for example. 11001000   00001010    00010100    00011110   But generally we see ip address on systems like   172.16.254.1   because it hard to remember that is why these 32 bit kept in grouping and   these 32 bits will be divided in 4 parts and it is in decimal system. We use also dotes between these 4 parts of 32 bits.   These four section also known as Octets. There is also another address known as Physical address also known as MAC address ( Media access control).   This address is in built on NI...

Hello ppl, My name is Vasu Birla and in this part we will know that how can we take backup of cisco switch configuration files and settings and after that how can we restore all backup files ,   so let’s do it .. Here is our topology on which we are going to perform this theory -      In this part our task is   transferring the all configuration files to server -   our all backup will be seen in the server’s configuration   mode   in TFTP files   - as below picture ............ Now go to switch   and run show command -    show run    then we will   show all the configuration files there   Sw1>en Sw1# show run   After this you will see all the configuration files Following commands is for backup files of switch sw1#copy running-config? sw1#copy running-config startup-config Destination filename [startup-config]?
