Now, as soon as we type this command, we see the parameters which we have to enter next. Therefore, now to copy the IOS file from the TFTP server we will use the command: Therefore, when we will reload the router, it will enter ROMMON mode. Now, as the file is deleted still the router is running because the IOS has already been loaded into RAM. Now, we will delete the IOS image from the router: Here, we have named it routerIOS.Īs shown in the above figure, the file has been copied to the TFTP server.

Destination filename – It is the name of the destination file that will be put in the TFTP server.

Address or name of remote host – It is the IP address of the TFTP server.

here, it is named 1.bin (shown in flash).

Source filename – It is the name of the IOS image file.

Now, as we can see in the above image it is asking for source filename, Address of remote host, and destination filename. Source filename? 1.binĪddress or name of remote host ? 10.1.1.2ĭestination filename ? routerios

Now, we will copy this file to our Tftp server by command: The router has IP address 10.1.1.1/24 and the TFTP server has IP address 10.1.1.2/24.īefore taking IOS backup, make sure the Tftp server and router are able to ping each other.Īs shown in the figure, we see an IOS image file in flash (.bin file) by command: Here is a simple topology in which there is a router (for which we will take IOS backup) and a TFTP server. Therefore, according to the need, FTP or TFTP is used. While on the other hand, it is less interactive than FTP. It uses UDP port number 69.īut TFTP is used where no authentication and control are required. TFTP is a simple file transfer protocol that is either used to put or get a file from a remote host. So to ignore conditions like these, a backup should be a must and here we will take a Cisco IOS image backup on the TFTP server.
